          Comment on Integration by long division by Nathan Hannon      Cache   Translate Page      
The method of long division works for solving any system Ax = b for x, where: 1) A is a linear operator (in more familiar forms of long division, this is multiplication by a real number or polynomial), acting on a vector space of which b is an element, and 2) you have some method of choosing y such that Ay = b + r, reducing the problem of solving Ax = b to the problem of solving Ay = r. Long division is just a notation for iterating this process. Of course, for this to do anything meaningful, r has to be "smaller" than b in some way. For long division of real numbers, we choose y such that r < b as numbers; for long division of polynomials, we choose y such that r has a lower degree than b. What I don't understand here is how we choose y in general. In this case (and many other integration by parts cases) there is an easy choice of y that works because we are reducing the power of x in the integral, but is there some more general way to choose y?

(This article was first published on R Curtis Miller's Personal Website , and kindly contributed toR-bloggers)

Introduction

I’ve spent the past few weeks writing about MCHT , my new package for Monte Carlo and bootstrap hypothesis testing. After discussing how to use MCHT safely , I discussed how to use it for maximized Monte Carlo (MMC) testing , then bootstrap testing . One may think I’ve said all I want to say about the package, but in truth, I’ve only barely passed the halfway point!

Today I’m demonstrating how general MCHT is, allowing one to use it for multiple samples and on non-univariate data. I’ll be doing so with two examples: a permutation test and the

test for significance of a regression model.

Permutation Test The idea of the permutation test dates back to Fisher (see [1]) and it forms the basis of computational testing for difference in mean. Let’s suppose that we have two samples with respective means and

, respectively. Suppose we wish to test

against


Beyond Univariate, Single-Sample Data with MCHT

using samples

and

, respectively.

If the null hypothesis is true and we also make the stronger assumption that the two samples were drawn from distributions that could differ only in their means, then the labelling of the two samples is artificial, and if it were removed the two samples would be indistinguishable. Relabelling the data and artificially calling one sample the

sample and the other the

sample would produce highly similar statistics to the one we actually observed. This observation suggests the following procedure:

Generate new datasets by randomly assigning labels to the combined sample of and . Compute copies of the test statistic on each of the new samples; suppose that the test statistic used is the difference in means, . Compute the test statistic on the actual sample and compare to the simulated statistics. If the actual statistic is relatively large compared to the simulated statistics, then reject the null hypothesis in favor of the alternative; otherwise, don’t reject.

In practice step 3 is done by computing a

-value representing the proportion of simulated statistics larger than the one actually computed.

Permutation Tests Using MCHT

The permutation test is effectively a bootstrap test, so it is supported by MCHT , though one may wonder how that’s the case when the parameters test_stat , stat_gen , and rand_gen only accept one parameter, x , representing the dataset (as opposed to, say, t.test() , which has an x and an optional y parameter). But MCHTest() makes very few assumptions about what object x actually is; if your object is either a vector or tabular, then the MCHTest object should not have a problem with it (it’s even possible a loosely structured list would be fine, but I have not tested this; tabular formats should cover most use cases).

In this case, putting our data in long-form format makes doing a permutation test fairly simple. One column will contain the group an observation belongs to while the other contains observation values. The test_stat function will split the data according to group, compute group-wise means, and finally compute the test statistic. rand_gen generates new dataset by permuting the labels in the data frame. stat_gen merely serves as the glue between the two.

The result is the following test.

library(MCHT) library(doParallel) registerDoParallel(detectCores()) ts <- function(x) { grp_means <- aggregate(value ~ group, data = x, FUN = mean) grp_means$value[1] - grp_means$value[2] } rg <- function(x) { x$group <- sample(x$group) x } sg <- function(x) { test_stat(x) } permute.test <- MCHTest(ts, sg, rg, seed = 123, N = 1000, localize_functions = TRUE) df <- data.frame("value" = c(rnorm(5, 2, 1), rnorm(10, 0, 1)), "group" = rep(c("x", "y"), times = c(5, 10))) permute.test(df) ## ## Monte Carlo Test ## ## data: df ## S = 1.3985, p-value = 0.036 Linear Regression F Test

Suppose for each observation in our dataset there is an outcome of interest,

, and there are variables that could together help predict the value of if they are known. Consider then the following linear regression model (with

):

The first question someone should asked when considering a regression model is whether it’s worth anything at all. An alternative approach to predicting

is simply to predict its mean value. That is, the model

is much simpler and should be preferred to the more complicated model listed above if it’s just as good at explaining the behavior of

for all . Notice the second model is simply the first model with all the coefficients

identically equal to zero.

The

-test (described in more detail here

) can help us decide between these two competing models. Under the null hypothesis, the second model is the true model.

The alternative says that at least one of the regressors is helpful in predicting

.

We can use the

statistic to decide between the two models:

and

are the residual sum of squares of models 1 and

2, respectively.

This test is called the

-test because usually the F-distribution is used to compute -values (as this is the distributiont the

statistic should follow when certain conditions hold, at least asymptotically if not exactly). What then would a bootstrap-based procedure look like?

If the null hypothesis is true then the best model for the data is this:

is the sample mean of and

is the residual. This suggests the following procedure:

Shuffle over all rows of the input dataset, with replacement, to generate new datasets. Compute statistics for each of the generated datasets. Compare the statistic of the actual dataset to the generated datasets’ statistics. F Test Using MCHT

Let’s perform the

test on a subset of the iris dataset. We will see if there is a relationship between the sepal length and sepal width among iris setosa

flowers. Below is an initial split and visualization:

library(dplyr) setosa <- iris %>% filter(Species == "setosa") %>% select(Sepal.Length, Sepal.Width) plot(Sepal.Width ~ Sepal.Length, data = setosa)
Beyond Univariate, Single-Sample Data with MCHT

There is an obvious relationship between the variables. Thus we should expect the test to reject the null hypothesis. That is what we would conclude if we were to run the conventional

test:

res <- lm(Sepal.Width ~ Sepal.Length, data = setosa) summary(res) ## ## Call: ## lm(formula = Sepal.Width ~ Sepal.Length, data = setosa) ## ## Residuals: ## Min 1Q Median 3Q Max ## -0.72394 -0.18273 -0.00306 0.15738 0.51709 ## ## Coefficients: ## Estimate Std. Error t value Pr(>|t|) ## (Intercept) -0.5694 0.5217 -1.091 0.281 ## Sepal.Length 0.7985 0.1040 7.681 6.71e-10 *** ## --- ## Signif. codes: 0 '***' 0.001 '**' 0.01 '*' 0.05 '.' 0.1 ' ' 1 ## ## Residual standard error: 0.2565 on 48 degrees of freedom ## Multiple R-squared: 0.5514, Adjusted R-squared: 0.542 ## F-statistic: 58.99 on 1 and 48 DF, p-value: 6.71e-10

Let’s now implement the procedure I described with MCHTest() .

ts <- function(x) { res <- lm(Sepal.Width ~ Sepal.Length, data = x) summary(res)$fstatistic[[1]] # Only way I know to automatically compute the # statistic } # rand_gen's function can use both x and n, and n will be the number of rows of # the dataset rg <- function(x, n) { x$Sepal.Width <- sample(x$Sepal.Width, replace = TRUE, size = n) x } b.f.test.1 <- MCHTest(ts, ts, rg, seed = 123, N = 1000) b.f.test.1(setosa) ## ## Monte Carlo Test ## ## data: setosa ## S = 58.994, p-value < 2.2e-16

Excellent! It reached the correct conclusion.

Conclusion

One may naturally ask whether we can write functions a bit more general than what I’ve shown here at least in the regression context. For example, one may want parameters specifying a formula so that the regression model isn’t hard-coded into the test. In short, the answer is yes; MCHTest objects try to pass as many parameters to the input functions as they can.

Here is the revised example that works for basically any formula:

ts <- function(x, formula) { res <- lm(formula = formula, data = x) summary(res)$fstatistic[[1]] } rg <- function(x, n, formula) { dep_var <- all.vars(formula)[1] # Get the name of the dependent variable x[[dep_var]] <- sample(x[[dep_var]], replace = TRUE, size = n) x } b.f.test.2 <- MCHTest(ts, ts, rg, seed = 123, N = 1000) b.f.test.2(setosa, formula = Sepal.Width ~ Sepal.Length) ## ## Monte Carlo Test ## ## data: setosa ## S = 58.994, p-value < 2.2e-16

This shows that you can have a lot of control over how MCHTest objects handle their inputs, giving you considerable flexibility.

          xts 0.11-2 on CRAN      Cache   Translate Page      
xts version 0.11-2 was published to CRAN yesterday. xts provides data structure and functions to work with time-indexed data.  This is a bug-fix release, with notable changes below: The xts method for shift.time() is now registered. Thanks to Philippe Verspeelt for the report and PR (#268, #273). An if-statement in the xts constructor will no longer try to use a logical vector with length __ 1. Code like if (c(TRUE, TRUE)) will throw a warning in an upcoming R release, and this patch will prevent that warning. Thanks to Hugh Parsonage for the report and PR (#270, #272). Fix subset when index(i) and i contain duplicates. Observations were being incorrectly dropped, and behavior is now consistent with zoo. Thanks to Stack Overflow user scs for the report, and Philippe Verspeelt for the help debugging (#275). Make column names for merge() results with unnamed objects shorter and more like zoo (#248). Previously, column names could be hundreds, even thousands, of characters. This change has the added benefit of making na.fill() much faster (#259). NOTE: This may BREAK existing code for integer unnamed objects. The to.period() family of functions now use the index timezone when converting intraday index values to daily values (or lower frequency). Previously, the dates would be calculated as UTC dates, instead of dates in the local timezone (as they are now). Thanks to Garrett See and Gabor Grothendieck for the reports (#53, #277). As always, I'm looking forward to your questions and feedback! If you have a question, please ask on Stack Overflow and use the [r] and [xts] tags. Or you can send an email to the R-SIG-Finance mailing list (you must subscribe to post). Open an issue on GitHub if you find a bug or want to request a feature, but please read the contributing guide first!
          ‘How do neural nets learn?’ A step by step explanation using the H2O Deep Learning algorithm.      Cache   Translate Page      
In my last blogpost about Random Forests I introduced the codecentric.ai Bootcamp. The next part I published was about Neural Networks and Deep Learning. Every video of our bootcamp will have example code and tasks to promote hands-on learning. While the practical parts of the bootcamp will be using Python, below you will find the English R version of this Neural Nets Practical Example, where I explain how neural nets learn and how the concepts and techniques translate to training neural nets in R with the H2O Deep Learning function. You can find the video on YouTube but as, as before, it is only available in German. Same goes for the slides, which are also currently German only. See the end of this article for the embedded video and slides. Neural Nets and Deep Learning Just like Random Forests, neural nets are a method for machine learning and can be used for supervised, unsupervised and reinforcement learning. The idea behind neural nets has already been developed back in the 1940s as a way to mimic how our human brain learns. That’s way neural nets in machine learning are also called ANNs (Artificial Neural Networks). When we say Deep Learning, we talk about big and complex neural nets, which are able to solve complex tasks, like image or language understanding. Deep Learning has gained traction and success particularly with the recent developments in GPUs and TPUs (Tensor Processing Units), the increase in computing power and data in general, as well as the development of easy-to-use frameworks, like Keras and TensorFlow. We find Deep Learning in our everyday lives, e.g. in voice recognition, computer vision, recommender systems, reinforcement learning and many more. The easiest type of ANN has only node (also called neuron) and is called perceptron. Incoming data flows into this neuron, where a result is calculated, e.g. by summing up all incoming data. Each of the incoming data points is multiplied with a weight; weights can basically be any number and are used to modify the results that are calculated by a neuron: if we change the weight, the result will change also. Optionally, we can add a so called bias to the data points to modify the results even further. But how do neural nets learn? Below, I will show with an example that uses common techniques and principles. Libraries First, we will load all the packages we need: tidyverse for data wrangling and plotting readr for reading in a csv h2o for Deep Learning (h2o.init initializes the cluster) library(tidyverse) library(readr) library(h2o) h2o.init(nthreads = -1) ## Connection successful! ## ## R is connected to the H2O cluster: ## H2O cluster uptime: 3 hours 46 minutes ## H2O cluster timezone: Europe/Berlin ## H2O data parsing timezone: UTC ## H2O cluster version: 3.20.0.8 ## H2O cluster version age: 1 month and 16 days ## H2O cluster name: H2O_started_from_R_shiringlander_jpa775 ## H2O cluster total nodes: 1 ## H2O cluster total memory: 3.16 GB ## H2O cluster total cores: 8 ## H2O cluster allowed cores: 8 ## H2O cluster healthy: TRUE ## H2O Connection ip: localhost ## H2O Connection port: 54321 ## H2O Connection proxy: NA ## H2O Internal Security: FALSE ## H2O API Extensions: XGBoost, Algos, AutoML, Core V3, Core V4 ## R Version: R version 3.5.1 (2018-07-02) Data The dataset used in this example is a customer churn dataset from Kaggle. Each row represents a customer, each column contains customer’s attributes We will load the data from a csv file: telco_data % select_if(is.numeric) %__% gather() %__% ggplot(aes(x = value)) + facet_wrap(~ key, scales = "free", ncol = 4) + geom_density() ## Warning: Removed 11 rows containing non-finite values (stat_density). … and barcharts for categorical variables. telco_data %__% select_if(is.character) %__% select(-customerID) %__% gather() %__% ggplot(aes(x = value)) + facet_wrap(~ key, scales = "free", ncol = 3) + geom_bar() Before we can work with h2o, we need to convert our data into an h2o frame object. Note, that I am also converting character columns to categorical columns, otherwise h2o will ignore them. Moreover, we will need our response variable to be in categorical format in order to perform classification on this data. hf % mutate_if(is.character, as.factor) %__% as.h2o Next, I’ll create a vector of the feature names I want to use for modeling (I am leaving out the customer ID because it doesn’t add useful information about customer churn). hf_X

Spending on security technology continues to soar. Nevertheless, data breaches and cyberattacks continue to make headlines at an incredible rate, with no relief in sight. The Online Trust Alliance reported that attacks in 2017 came from a myriad of vectors, such as phishing and ransomware, and that the number of attacks doubled to nearly 160,000 incidents per year over 2016. What’s worse, estimates for the number of unreported attacks exceed 350,000 annually. While enterprises typically dominate the headlines, organizations of all sizes are affected by cyber incidents.

Smad4-dependent regulation of type I collagen expression in the muscle of grass carp fed with faba bean.

Gene. 2018 Oct 26;685:32-41

Authors: Yu EM, Ma LL, Ji H, Li ZF, Wang GJ, Xie J, Yu DG, Kaneko G, Tian JJ, Zhang K, Gong WB

Abstract
Smad4 is the key regulator in the transforming growth factor β1 (TGF-β1)/Smads signal pathway, and is also the crux of the regulation of type I collagen expression in mammals. In fish, however, the relationship between Smad4 and type I collagen is still unknown. Given the widely accepted importance of type I collagen in fish muscle hardness, we seek to explore this issue by analyzing the expressions of the TGF-β1/Smads pathway molecules and type I collagen in the muscle of crisp grass carp fed with faba bean, which shows increased muscle hardness. The study found that (1) in the process of feeding the grass carp with faba bean, the mRNA and protein expressions of TGF-β1, Smad2 and Smad4 all increased along with the increase of type I collagen expression (Col1α1 and Col1α2); (2) one day after the injection of Smad4 over-expression vector, both mRNA and protein expressions of Col1α1 and Col1α2 significantly increased, reaching the maximum on the 2nd and 5th day, respectively; (3) one day after the injection of Smad4 RNAi interference vector, the mRNA and protein expressions of Col1α1 and Col1α2 decreased, reaching the minimum on the 5th day. These results revealed that Smad4 is the major regulator of type I collagen in the muscle of grass carp fed with faba bean. This study would provide an important mechanistic basis for nutritional regulation of type I collagen in the muscle of fish.

Cloning and functional analysis of the VcCXIP4 and VcYSL6 genes as Cd-regulating genes in blueberry.

Gene. 2018 Oct 31;:

Authors: Chen S, Liu Y, Deng Y, Liu Y, Dong M, Tian Y, Sun H, Li Y

Abstract
Blueberries (Vaccinium ssp.) show relatively high resistance to pollution and have been reported to successfully colonize acid and heavy metal-contaminated soils. Blueberries were subjected to cadmium stress using a simulated pot-culture method. The intact CDS regions of VcCXIP4 and VcYSL6 were obtained, VcCXIP4 was located in the nucleus, while VcYSL6 was located in the chloroplast. Both genes were constructed into a modified plant expression vector pCambia1301 for tobacco transformation with agrobacterium infection methods. Results showed that VcCXIP4 did not function alone in regulating cadmium (Cd) transport. Cd content of Cd in the leaves of VcYSL6 transgenic tobacco by 15.57% under high Cd concentration. Both, VcCXIP4 and VcYSL6 genes were up-regulated under Cd stress. Blueberry primarily accumulated excess Cd in the root, but Cd content in the fruit was almost independent of Cd content in the soil. Further, the effect of soil Cd content on fruit Cd content was not significant. VcCXIP4 is likely to interact with other proteins to regulate excess Cd in blueberry, while VcYSL6 is a Cd transporter required for excess Cd detoxification in blueberry.

          Your Client Engagement Program Isn't Doing What You Think It Is.      Cache   Translate Page      

Amazing products without engaged clients are bound to fail, and companies claiming to have found the single best solution to client engagement are only fooling themselves.

What seems to work today to keep your clients engaged won't necessarily work tomorrow. The "optimal" client engagement tactic for your product will change over time and companies must be fluid and adaptable to accommodate ever-changing client needs and business strategies. Becoming complacent by settling for a strategy that works "for now" or "well enough" leads to risk aversion and unrealized potential. Constant recalibration is crucial, yet exploration can be costly and may lead nowhere. A principled approach to finding the right client engagement tactics at any point in time is essential.

Enter, Bandits!

Here at Stitch Fix, we prioritize personalization in every communication, interaction, and outreach opportunity we have with clients. Contextual bandits are one of the ways we enable this personalization.

In a nutshell, a contextual bandit is a framework that allows you to use algorithms to learn the most effective strategy for each individual client, while simultaneously using randomization to continuously track how successful each of your different action choices are.

Implementing a contextual-bandit-based client engagement program will allow you to:

  1. Understand how the performance of your tactics change over time;
  2. Select a personalized tactic for each client based on his or her unique characteristics;
  3. Introduce new tactics relevant to subpopulations of clients in a systematic manner; and
  4. Continuously refine and improve your algorithms.

Part 1: There are Significant Limitations to Typical Client Engagement Approaches.

Let's set up a simple, clear example.

Current state: There are a group of individuals who have used your product in the past, but are no longer actively engaged. You want to remind them about your great product.

Proposed idea: We'll do an email campaign. Clients who haven't interacted with you for a while will be eligible to receive this email, and the purpose is to get them to visit your website. (Note that instead of email, we could just as easily use a widget on a website, a letter in the mail, or any other method of communicating with clients.)

The One Size Fits All Method

Your team brainstorms several tactics and decides to run a test to see which one works best. Let's use a simple three-tactic example here:

  1. Tactic A: no email. This is our control, which we can use to establish a baseline for client behavior;
  2. Tactic B: an emailed invitation to work 1-on-1 with (in our case) an expert stylist via email to make sure we get you exactly what you want; and
  3. Tactic C: an emailed promotional offer.

You run this test and find that Tactic B works the best. As such, you decide to scale Tactic B out to all clients, since it is expected to maximize return.

This is an endpoint in many marketing and product pipelines. The team celebrates the discovery of the "best" strategy and now it's time to move on to the next project; Case closed.

Main Limitations with this Approach

  1. You have no idea how long Tactic B will continue to be the best. Let's say over the next year your product improves and expands, leading to a change in the demographics of your client base. How confident are you that Tactic B is still the best?
  2. There is no personalization. All clients are receiving Tactic B. Some subsegment of clients likely would have performed better with Tactic C, but by scaling out Tactic B to all clients, these clients did not receive their optimal tactic.
  3. You are not taking advantage of key pieces of information. Since everyone in this audience was a previous client, you have information on how they interacted with you in the past! To address this, teams frequently build out a decision tree that groups their clients into broad categories (such as by age or tenure with the company). However…
  4. Using decision trees to group clients into categories leads to unoptimized outreach programs. Each category of clients might get a different tactic, and as new tactics or categories are created, these trees can grow larger and larger. Many of you have seen it: 10+ branch decision trees that try to segment a client base into different categories. When these trees grow too large, not only do they become difficult to manage, but it becomes more and more questionable whether or not you are actually doing what you think you are doing.
Does this look like your program?

Part 2: Multi-Armed Bandits Allows Continuous Monitoring

The above situation is common, suboptimal, and headache-inducing. Developing a testing and implementation strategy with bandits can remove or reduce many of these limitations.

A standard multi-armed bandit is the most basic bandit implementation. It allows us to allocate a small amount of clients to continuously explore how different tactics are performing, while giving the majority of clients the current one-size-fits-all best-performing tactic. The standard implementation updates which tactic is best after every client interaction, allowing you to quickly settle on the most effective large-scale tactic.

To get into more technical detail, a multi-armed bandit is a system where you must select one action from a set of possible actions for a given 'resource' (in our example, the 'resource' is a client). The 'reward' (if a client responds to the offer or not) for the selected action is exposed, but the reward for all other actions remains unknown (we don't know what a specific client would have done if we had sent them a different offer!).

The reward for a given action can be thought of as a random reward drawn from a probability distribution specific to that action. Because these probability distributions may not be known or may change over time, we want this system to allocate some resources to improving our understanding of the different choices ('exploration') while simultaneously maximizing our expected gains based on our historical knowledge ('exploitation'). Our goal is to minimize "regret," defined as the difference between the sum of rewards if we used an optimal strategy and the actual sum of rewards realized.

Mathematically, if we have a bandit with K choices (K arms), we can define a reward for 1 ≤ i ≤ K and n ≥ 1, where i is an arm of the bandit and n is the round we are currently considering.

Each round yields a reward The reward of each round is a function of which arm was selected for the client, and is assumed to be independent of both the rewards from previous rounds and the distributions of the other arms, and only dependent upon the probability distribution associated with the selected arm.

We thus want to minimized our regret, defined as:

, where total number of rounds, maximum reward, and is the reward in round n from selecting arm i.

There are numerous strategies that can be utilized to select how clients are allocated to either exploitation or exploration in order to minimize the regret of your bandit. For this article, we will consider the simplest, called the epsilon-greedy algorithm. In the epsilon-greedy algorithm, the best action is selected for 1−ϵ of your audience entering your program, and a random action is selected for the remaining ϵ of your audience. ϵ can be set to any value, depending on how many resources you want to allocate to exploration. For example, if ϵ is set to 0.1, then 10% of your audience is being directed to exploration, and 90% of your audience is being directed to your best tactic. If desired, ϵ can be decreased over time to reduce the total regret of your system. Other popular allocation strategies that can reduce the overall regret of your system include Thompson sampling and UCB1[1][2].

Back to our Example

Let’s get back to our 3-tactic email test, and set up a standard multi-armed bandit. We need to decide to reach out to a client with either Tactic A, B, or C. We are going to use an epsilon-greedy approach and set ϵ=0.1. 10% of our clients will randomly be presented with one of the three tactics. The other 90% will receive whichever tactic is the current top-performer. Each time we give a client a tactic, we update the score for that tactic. We then examine the performance of the different tactics, and re-assign the best-performing tactic to the one with the highest score.

In the early stages of a standard multi-armed bandit, switching may occur frequently in the first few passes, but the pipeline will quickly stabalize.

The above animation demonstrates a simple, standard multi-armed bandit to help get you started thinking about how a bandit implementation might look. This example already allows us to continuously monitor how tactics are performing and actively redirects most of our audience to the current "best" tactic, but there is plenty more we can do to improve performance! For example, if we want to further minimize regret, we would want to use a more powerful regret-minimization technique (UCB1, Thompson Sampling, etc.) If we are nervous about our client population changing over time, we can implement a forgetting factor to down-weight older data points. New tactics can be added to this framework in a similar manner.

Part 3: Personalize Outreach with Contextual Bandits

While we have already improved upon our original example, let's take this a step further to get to true personalization.

Contextual bandits provide an extension to the bandit framework where a context (feature-vector) is associated with each client.[3] This allows us to personalize the action taken on each individual client, rather than simply applying the overall best tactic. For example, while Tactic B might perform the best if applied to all clients, there are certainly some clients who would respond better to Tactic C.

What this means in terms of our example is that instead of 90% of our clients being sent the one-size-fits-all best email, these clients instead enter our "selection algorithm." We then read in relevant features of these clients to decide which outreach tactic best suits each client’s needs and results in the best outcomes. We continue to assign 10% clients to a random tactic, because this lets us know the unbiased performance of each tactic and provides us with data to periodically retrain our selection algorithm.

To get started, we need to take some unbiased data and train a machine learning model. Let’s assume we have been running the multi-arm bandit above: because we randomly assigned clients to our different tactics, we can use this data to train our algorithm! The point here is to understand which clients we should be assigning to each tactic, or, for a given client, which tactic gives this client the highest probability of having a positive outcome.

In a Contextual Bandit, we use client features to select the best tactic for the majority of our clients and continue to pull in data from our randomly allocated clients to retrain our algorithm.

While a multi-armed bandit can be relatively quick to implement, a contextual bandit adds a decent amount of complexity to our problem. In addition to training and applying a machine learning model to the majority of clients, there are a number of additional behind-the-scenes steps that must be taken: for example, we need to establish a cadence for retraining this model as we continue to acquire more data, as well as build out significantly more logging in order to track from which pathway clients are being assigned to different tactics.

Why do we care about which pathway clients received an offer from? If we use an algorithm to assign a tactic to a client, clients with certain characteristics are more likely to be assigned to certain tactics. This is why it is important to have some clients assigned randomly: we can be confident that, in the random assignments, the underlying client distributions are the same for all tactics.

Contextual Considerations

Depending on the regret-minimization strategy, there may be restrictions on the type of model you can build. For example, using an epsilon-greedy strategy allows you to use any model you like. However, with Thompson sampling, using a non-linear model introduces significant additional challenges.[5] When deciding how to approach regret minimization, make sure to take your desired modeling approach into account.

No implementation is perfect, and bandits are no exception. Both multi-armed bandits and contextual bandits are best utilized when we have a clear, well-defined 'reward' – maybe this is clicking on a webpage banner, or clicking through an email, or purchasing something. If you can't concretely define a reward, you can't say whether or not a tactic was successful, let alone train a model. In addition, if you have significantly delayed feedback you will have to do some additional work to get everything running smoothly[4]. Contextual bandits also lead to more complex code, which gives more room for things to break when compared to implementing simpler strategies.

Finally, think carefully about real-world restrictions: for example, while a contextual bandit can support a large number of tactics, if you have very few clients entering the program you are not going to be gaining much information from your random test group ϵ . In this case, it may be wise to restrict the number of tactics to something manageable. Remember though, you can always remove tactics to make room for new ones!

Part 4: Summary and Final Thoughts

Expanding your program from using business-logic-driven decision making to model-based decision making can significantly improve the performance of your client engagement strategies, and bandits can be a great tool to facilitate this transition.

While the example we used involved email, this same pipeline can be applied in a variety of different domains. Other examples include prioritizing widgets on a webpage, modifying the flow clients experience as they click through forms on your website, or many other situations where you are performing client outreach.

If you currently have a single tactic scaled out to all clients and are not gathering any unbiased data, one viable approach to improve this situation would be to first transition to a multi-armed bandit, and then at a later timepoint transition to a contextual bandit. A basic multi-armed bandit can be quick to implement and allow you to begin gathering unbiased data. Eventually, utilizing a contextual bandit in your client engagement strategy will allow you to active adjust to changing client climates and needs, continuously test strategies, and personalize, personalize, personalize!

          BMW Z4 M40i 2018 review      Cache   Translate Page      
BMW Z4 M40i BMW’s Porsche Boxster rival is better to drive than ever, although it still makes a better high-day open-top cruiser than a true sports car The BMW Z4 has brought stability to its maker’s sports car offering. For more than a decade before it arrived, Munich seemed only to be experimenting with various executions of two-seat good-time cars. The Z1, Z3 and Z8 had plenty of novelty value, but none won enough commercial success to survive beyond one model generation (although that latter fact seems a bit bonkers when you think that secondhand values of Z8s have now risen well north of £200,000).The Z4, on the other hand, has been successful enough to convince BMW to directly replace it not once but twice. The latest, third-generation version drops the folding metal hard-top of the second, but it's still slightly longer, wider and heavier than its immediate predecessor. Chunkier or otherwise, though, BMW will tell you that this is an attempt to reverse the move made by its predecessor away from uncompromising driver appeal – to represent BMW’s traditional sporting DNA as best a modern front-engined, rear-wheel-drive roadster can and maybe even give owners of the four-cylinder Porsche 718 Boxster S greater pause for a silken six-pot reverie than it has managed before.This is the car Munich has been developing in tandem with industry giant Toyota since 2013, of course – the platform sibling of the incoming Supra. That fact, more than anything, might be the reason why Munich hasn’t shrunk it down or changed it around too much, because doing so would only have made engineering the car on a common platform harder.What BMW has done, however, is to entirely redesign the car’s suspension (struts featuring up front and, for the first time in a Z4, a five-link system at the rear). Lightweight aluminium components have been adopted to save on unsprung mass, while new subframe mounting techniques have been used at both ends and the tracks are wider – by a significant 98mm at the front.At launch, buyers will be able to choose between 194bhp and 255bhp turbocharged 2.0-litre petrol engines in the 20i and 30i respectively. A 3.0-litre turbo straight six (M40i), with M Performance derivative status, glitters away temptingly at the top of the range and is endowed with 335bhp and 369lb ft of torque (which, Z4 fans will note, is actually no more grunt than the outgoing Z4 sDrive35iS had). The headline version of the new car gets lightweight 18in alloy wheels as standard, as well as an eight-speed automatic gearbox, lowered and adaptively damped sport suspension, uprated brakes and a torque-vectoring electronic locking differential.
          Esports vs. pro sports: Jeremy Lin is betting on both       Cache   Translate Page      

Gaming companies control the games and therefore own the intellectual property on which eSports are based on. They have the scope to control the evolution of the esports sector in a way that was never open to conventional sports. That represents two important revenue vectors. The first is that the shelf-life of games is extended. Historically games have been discounted within about 12 months of release and once a player gets about 40 hours of game time they set the title aside. However, with an eSport constantly boosting visibility the legacy game has the potential to continue to attract new players well after its release date.

          Deep Self-Paced Residual Network for Multispectral Images Classification Based on Feature-Level Fusion      Cache   Translate Page      
The classification methods based on fusion techniques of multisource multispectral (MS) images have been studied for a long time. However, it may be difficult to classify these data based on a feature level while avoiding the inconsistency of data caused by multisource and multiple regions or cities. In this letter, we propose a deep learning structure called 2-branch SPL-ResNet which combines the self-paced learning with deep residual network to classify multisource MS data based on the feature-level fusion. First, a 2-D discrete wavelet is used to obtain the multiscale features and sparse representation of MS data. Then, a 2-branch SPL-ResNet is established to extract respective characteristics of the two satellites. Finally, we implement the feature-level fusion by cascading the two feature vectors and then classify the integrated feature vector. We conduct the experiments on Landsat_8 and Sentinel_2 MS images. Compared with the commonly used classification methods such as support vector machine and convolutional neural networks, our proposed 2-branch SPL-ResNet framework has higher accuracy and more robustness.
          Feasibility Study of Ore Classification Using Active Hyperspectral LiDAR      Cache   Translate Page      
Recently, a major effort has been made to develop methods or tools for rock characterization and mineral content mapping. Light detection and ranging (LiDAR) is an efficient active remote sensing technique for collecting geometry information about rock surfaces. However, traditional LiDAR sensors work with a single-wavelength laser source, and it is unfeasible to obtain spectral information using one LiDAR sensor. The combination of hyperspectral imaging and LiDAR techniques is an emerging method for acquiring spatial and spectral information simultaneously that allows remote mapping of high-resolution mineral content and distributions and identifies subtle chemical variations. Unfortunately, spatial and spectral data registration, which introduces additional complicated data processing, is an inevitable and essential issue for this method. In this letter, first, we investigate the feasibility of ore classification applications with hyperspectral LiDAR (HSL). HSL consists of 17 spectral channels covering the visible–shortwave infrared (SWIR) spectral range. Spatial and spectral information about seven different ore samples is obtained under a controlled laboratory environment using HSL. The standard deviation of the distance measurements is less than 1.1 cm for different spectral channels, and the classification accuracy can reach 100% if all 17 spectral measurements are used. To optimize the system design with lower cost and system complexity, a spectral band selection criterion is built based on the feature contribution degree (FCD), which is calculated using the normalized variance of the reflectance values for different ore samples at each wavelength. Two different strategies of FCD selection are tested to generate vectors: ascending sequences and descending sequences. Feature vectors with descending sequences have better classification accuracy. In addition, the results show that the classification accuracy can reach 100&#- 0025; with the feature vector of the seven largest FCD values compared to 59.57% for the feature vector with the seven smallest FCD values. Moreover, we find that the channels with high FCD values are primarily centered in SWIR bands. This result could be a reference for optimizing the hardware design of HSL for ore classification or mineral identification.

          Michael Snoyman: Iterators and Errors - Rust Crash Course lesson 3      Cache   Translate Page      

Last time, we finished off with a bouncy ball implementation with some downsides: lackluster error handling and ugly buffering. It also had another limitation: a static frame size. Today, we’re going to address all of these problems, starting with that last one: let’s get some command line arguments to control the frame size.

This post is part of a series based on teaching Rust at FP Complete. If you’re reading this post outside of the blog, you can find links to all posts in the series at the top of the introduction post. You can also subscribe to the RSS feed.

Like last time, I’m going to expect you, the reader, to be making changes to the source code along with me. Make sure to actually type in the code while reading!

Command line arguments

We’re going to modify our application as follows:

  • Accept two command line arguments: the width and the height
  • Both must be valid u32s
  • Too many or too few command line arguments will result in an error message

Sounds easy enough. In a real application, we would use a proper argument-handling library, like clap. But for now, we’re going lower level. Like we did for the sleep function, let’s start by searching the standard library docs for the word args. The first two entries both look relevant.

  • std::env::Args An iterator over the arguments of a process, yielding a String value for each argument.
  • std::env::args Returns the arguments which this program was started with (normally passed via the command line).

Now’s a good time to mention that, by strong convention:

  • Module names (like std and env) and function names (like args) are snake_cased
  • Types (like Args) are PascalCased
    • Exception: primitives like u32 and str are lower case

The std module has an env module. The env module has both an Args type and a args function. Why do we need both? Even more strangely, let’s look at the type signature for the args function:

pub fn args() -> Args

The args function returns a value of type Args. If Args was a type synonym for, say, a vector of Strings, this would make sense. But that’s not the case. And if you check out its docs, there aren’t any fields or methods exposed on Args, only trait implementations!

The extra datatype pattern

Maybe there’s a proper term for this in Rust, but I haven’t seen it myself yet. (If someone has, please let me know so I can use the proper term.) There’s a pervasive pattern in the Rust ecosystem, which in my experience starts with iterators and continues to more advanced topics like futures and async I/O.

  • We want to have composable interfaces
  • We also want high performance
  • Therefore, we define lots of helper data types that allow the compiler to perform some great optimizations
  • And we define traits as an interface to let these types compose nicely with each other

Sound abstract? Don’t worry, we’ll make that concrete in a bit. Here’s the practical outcome of all of this:

  • We end up programming quite a bit against traits, which provide a common abstractions and lots of helper functions
  • We get a matching data type for many common functions
  • Often times, our type signatures will end up being massive, representing all of the different composition we performed (though the new-ish -> impl Iterator style helps with that significantly, see the announcement blog post for more details)

Alright, with that out of the way, let’s get back to command line arguments!

CLI args via iterators

Let’s play around in an empty file before coming back to bouncy. (Either use cargo new and cargo run, or use rustc directly, your call.) If I click on the expand button next to the Iterator trait on the Args docs page, I see this function:

fn next(&mut self) -> Option<String>

Let’s play with that a bit:

use std::env::args;

fn main() {
    let mut args = args(); // Yes, that name shadowing works
    println!("{:?}", args.next());
    println!("{:?}", args.next());
    println!("{:?}", args.next());
    println!("{:?}", args.next());
}

Notice that we had to use let mut, since the next method will mutate the value. Now I’m going to run this with cargo run foo bar:

$ cargo run foo bar
   Compiling args v0.1.0 (/Users/michael/Desktop/tmp/args)
    Finished dev [unoptimized + debuginfo] target(s) in 1.60s
     Running `target/debug/args foo bar`
Some("target/debug/args")
Some("foo")
Some("bar")
None

Nice! It gives us the name of our executable, followed by the command line arguments, returning None when there’s nothing left. (For pedants out there: command line arguments aren’t technically required to have the command name as the first argument, it’s just a really strong convention most tools follow.)

Let’s play with this some more. Can you write a loop that prints out all of the command line arguments and then exits? Take a minute, and then I’ll provide some answers.

Alright, done? Cool, let’s see some examples! First, we’ll loop with return.

use std::env::args;

fn main() {
    let mut args = args();
    loop {
        match args.next() {
            None => return,
            Some(arg) => println!("{}", arg),
        }
    }
}

We also don’t need to use return here. Instead of returning from the function, we can just break out of the loop:

use std::env::args;

fn main() {
    let mut args = args();
    loop {
        match args.next() {
            None => break,
            Some(arg) => println!("{}", arg),
        }
    }
}

Or, if you want to save on some indentation, you can use the if let.

use std::env::args;

fn main() {
    let mut args = args();
    loop {
        if let Some(arg) = args.next() {
            println!("{}", arg);
        } else {
            break;
            // return would work too, but break is nicer
            // here, as it is more narrowly scoped
        }
    }
}

You can also use while let. Try to guess what that would look like before checking the next example:

use std::env::args;

fn main() {
    let mut args = args();
    while let Some(arg) = args.next() {
        println!("{}", arg);
    }
}

Getting better! Alright, one final example:

use std::env::args;

fn main() {
    for arg in args() {
        println!("{}", arg);
    }
}

Whoa, what?!? Welcome to one of my favorite aspects of Rust. Iterators are a concept built into the language directly, via for loops. A for loop will automate the calling of next(). It also hides away the fact that there’s some mutable state at play, at least to some extent. This is a powerful concept, and allows a lot of code to end up with a more functional style, something I happen to be a big fan of.

Skipping

It’s all well and good that the first arguments in the name of the executable. But we typically don’t care about that. Can we somehow skip that in our output? Well, here’s one approach:

use std::env::args;

fn main() {
    let mut args = args();
    let _ = args.next(); // drop it on the floor
    for arg in args {
        println!("{}", arg);
    }
}

That works, but it’s a bit clumsy, especially compared to our previous version that had no mutable variables. Maybe there’s some other way to skip things. Let’s search the standard library again. I see the first results as std::iter::Skip and std::iter::Iterator::skip. The former is a data type, and the latter is a method on the Iterator trait. Since our Args type implements the Iterator trait, we can use it. Nice!

Side note Haskellers: skip is like drop in most Haskell libraries, like Data.List or vector. drop has a totally different meaning in Rust (dropping owned data), so skip is a better name in Rust.

Let’s look at some signatures from the docs above:

pub struct Skip<I> { /* fields omitted */ }
fn skip(self, n: usize) -> Skip<Self>

Hmm… deep breaths. Skip is a data type that is parameterized over some data type, I. This is a common pattern in iterators: Skip wraps around an existing data type and adds some new functionality to how it iterates. The skip method will consume an existing iterator, take the number of arguments to skip, and return a new Skip<OrigDataType> value. How do I know it consumes the original iterator? The first parameter is self, not &self or &mut self.

That seemed like a lot of concepts. Fortunately, usage is pretty easy:

use std::env::args;

fn main() {
    for arg in args().skip(1) {
        println!("{}", arg);
    }
}

Nice!

Exercise 1 Type inference lets the program above work just fine without any type annotations. However, it’s a good idea to get used to the generated types, since you’ll see them all too often in error messages. Get the program below to compile by fixing the type signature. Try to do it without using compiler at first, since the error messages will almost give the answer away.

use std::env::{args, Args};
use std::iter::Skip;

fn main() {
    let args: Args = args().skip(1);
    for arg in args {
        println!("{}", arg);
    }
}

This layering-of-datatypes approach, as mentioned above, is a real boon to performance. Iterator-heavy code will often compile down to an efficient loop, comparable with the best hand-rolled loop you could have written. However, iterator code is much higher level, more declarative, and easy to maintain and extend.

There’s a lot more to iterators, but we’re going to stop there for the moment, since we still want to process our command line parameters, and we need to learn one more thing first.

Parsing integers

If you search the standard library for parse, you’ll find the str::parse method. The documentation does a good job of explaining things, I won’t repeat that here. Please go read that now.

OK, you’re back? Turbofish is a funny name, right?

Take a crack at writing a program that prints the result of parsing each command line argument as a u32, then check my version:

fn main() {
    for arg in std::env::args().skip(1) {
        println!("{:?}", arg.parse::<u32>());
    }
}

And let’s try running it:

$ cargo run one 2 three four 5 6 7
Err(ParseIntError { kind: InvalidDigit })
Ok(2)
Err(ParseIntError { kind: InvalidDigit })
Err(ParseIntError { kind: InvalidDigit })
Ok(5)
Ok(6)
Ok(7)

When the parse is successful, we get the Ok variant of the Result enum. When the parse fails, we get the Err variant, with a ParseIntError telling us what went wrong. (The type signature on parse itself uses some associated types to indicate this type, we’re not going to get into that right now.)

This is a common pattern in Rust. Rust has no runtime exceptions, so we track potential failure at the type level with actual values.

Side note You may think of panics as similar to runtime exceptions, and to some extent they are. However, you’re not able to properly recover from panics, making them different in practice from how runtime exceptions are used in other languages like Python.

Parse our command line

We’re finally ready to get started on our actual command line parsing! We’re going to be overly tedious in our implementation, especially with our data types. After we finish implementing this in a blank file, we’ll move the code into the bouncy implementation itself. First, let’s define a data type to hold a successful parse, which will contain the width and the height.

Challenge Will this be a struct or an enum? Can you try implementing this yourself first?

Since we want to hold onto multiple values, we’ll be using a struct. I’d like to use named fields, so we have:

struct Frame {
    width: u32,
    height: u32,
}

Next, let’s define an error type to represent all of the things that can go wrong during this parse. We have:

  • Too few arguments
  • Too many arguments
  • Invalid integer

Challenge Are we going to use a struct or an enum this time?

This time, we’ll use an enum, because we’ll only detect one of these problems (whichever we notice first). Officianados of web forms and applicative parsing may scoff at this and say we should detect all errors, but we’re going to be lazy.

enum ParseError {
    TooFewArgs,
    TooManyArgs,
    InvalidInteger(String),
}

Notice that the InvalidInteger variant takes a payload, the String it failed parsing. This is what makes enums in Rust so much more powerful than enumerations in most other languages.

Challenge We’re going to write a parse_args helper function. Can you guess what its type signature will be?

Combining all of the knowledge we established above, here’s an implementation:

#[derive(Debug)]
struct Frame {
    width: u32,
    height: u32,
}

#[derive(Debug)]
enum ParseError {
    TooFewArgs,
    TooManyArgs,
    InvalidInteger(String),
}

fn parse_args() -> Result<Frame, ParseError> {
    use self::ParseError::*; // bring variants into our namespace

    let mut args = std::env::args().skip(1);

    match args.next() {
        None => Err(TooFewArgs),
        Some(width_str) => {
            match args.next() {
                None => Err(TooFewArgs),
                Some(height_str) => {
                    match args.next() {
                        Some(_) => Err(TooManyArgs),
                        None => {
                            match width_str.parse() {
                                Err(_) => Err(InvalidInteger(width_str)),
                                Ok(width) => {
                                    match height_str.parse() {
                                        Err(_) => Err(InvalidInteger(height_str)),
                                        Ok(height) => Ok(Frame {
                                            width,
                                            height,
                                        }),
                                    }
                                }
                            }
                        }
                    }
                }
            }
        }
    }
}

fn main() {
    println!("{:?}", parse_args());
}

Holy nested blocks Batman, that is a lot of indentation! The pattern is pretty straightforward:

  • Pattern match
  • If we got something bad, stop with an Err
  • If we got something good, keep going

Haskellers at this point are screaming about do notation and monads. Ignore them. We’re in the land of Rust, we don’t take kindly to those things around here. (Someone please yell at me for that terrible pun.)

Exercise 2 Why didn’t we need to use the turbofish on the call to parse above?

What we want to do is return early from our function. You know what keyword can help with that? That’s right: return!

fn parse_args() -> Result<Frame, ParseError> {
    use self::ParseError::*;

    let mut args = std::env::args().skip(1);

    let width_str = match args.next() {
        None => return Err(TooFewArgs),
        Some(width_str) => width_str,
    };

    let height_str = match args.next() {
        None => return Err(TooFewArgs),
        Some(height_str) => height_str,
    };

    match args.next() {
        Some(_) => return Err(TooManyArgs),
        None => (),
    }

    let width = match width_str.parse() {
        Err(_) => return Err(InvalidInteger(width_str)),
        Ok(width) => width,
    };

    let height = match height_str.parse() {
        Err(_) => return Err(InvalidInteger(height_str)),
        Ok(height) => height,
    };

    Ok(Frame {
        width,
        height,
    })
}

Much nicer to look at! However, it’s still a bit repetitive, and littering those returns everywhere is subjectively not very nice. In fact, while typing this up, I accidentally left off a few of the returns and got to stare at some long error messages. (Try that for yourself.)

Question mark

Side note The trailing question mark we’re about to introduce used to be the try! macro in Rust. If you’re confused about the seeming overlap: it’s simply a transition to new syntax.

The pattern above is so common that Rust has built in syntax for it. If you put a question mark after an expression, it basically does the whole match/return-on-Err thing for you. It’s more powerful than we’ll demonstrate right now, but we’ll get to that extra power a bit later.

To start off, we’re going to define some helper functions to:

  • Require another argument
  • Require that there are no more arguments
  • Parse a u32

All of these need to return Result values, and we’ll use a ParseError for the error case in all of them. The first two functions need to take a mutable reference to our arguments. (As a side note, I’m going to stop using the skip method now, because if I do it will give away the solution to exercise 1.)

use std::env::Args;

fn require_arg(args: &mut Args) -> Result<String, ParseError> {
    match args.next() {
        None => Err(ParseError::TooFewArgs),
        Some(s) => Ok(s),
    }
}

fn require_no_args(args: &mut Args) -> Result<(), ParseError> {
    match args.next() {
        Some(_) => Err(ParseError::TooManyArgs),
        // I think this looks a little weird myself.
        // But we're wrapping up the unit value ()
        // with the Ok variant. You get used to it
        // after a while, I guess
        None => Ok(()),
    }
}

fn parse_u32(s: String) -> Result<u32, ParseError> {
    match s.parse() {
        Err(_) => Err(ParseError::InvalidInteger(s)),
        Ok(x) => Ok(x),
    }
}

Now that we have these helpers defined, our parse_args function is much easier to look at:

fn parse_args() -> Result<Frame, ParseError> {
    let mut args = std::env::args();

    // skip the command name
    let _command_name = require_arg(&mut args)?;

    let width_str = require_arg(&mut args)?;
    let height_str = require_arg(&mut args)?;
    require_no_args(&mut args)?;
    let width = parse_u32(width_str)?;
    let height = parse_u32(height_str)?;

    Ok(Frame { width, height })
}

Beautiful!

Forgotten question marks

What do you think happens if you forget the question mark on the let width_str line? If you do so:

  • width_str will contain a Result<String, ParseError> instead of a String
  • The call to parse_u32 will not type check
error[E0308]: mismatched types
  --> src/main.rs:50:27
   |
50 |     let width = parse_u32(width_str)?;
   |                           ^^^^^^^^^ expected struct `std::string::String`, found enum `std::result::Result`
   |
   = note: expected type `std::string::String`
              found type `std::result::Result<std::string::String, ParseError>`

That’s nice. But what will happen if we forget the question mark on the require_no_args call? We never use the output value there, so it will type check just fine. Now we have the age old problem of C: we’re accidentally ignoring error codes!

Well, not so fast. Check out this wonderful warning from the compiler:

warning: unused `std::result::Result` which must be used
  --> src/main.rs:49:5
   |
49 |     require_no_args(&mut args);
   |     ^^^^^^^^^^^^^^^^^^^^^^^^^^^
   |
   = note: #[warn(unused_must_use)] on by default
   = note: this `Result` may be an `Err` variant, which should be handled

That’s right: Rust will detect if you’ve ignored a potential failure. There is a hole in this in the current code sample:

let _command_name = require_arg(&mut args);

That doesn’t trigger the warning, since in let _name = blah;, the leading underscore says “I know what I’m doing, I don’t care about this value.” Instead, it’s better to write the code without the let:

require_arg(&mut args);

Now we get a warning, which can be solved with the added trailing question mark.

Exercise 3

It would be more convenient to use method call syntax. Let’s define a helper data type to make this possible. Fill in the implementation of the code below.

#[derive(Debug)]
struct Frame {
    width: u32,
    height: u32,
}

#[derive(Debug)]
enum ParseError {
    TooFewArgs,
    TooManyArgs,
    InvalidInteger(String),
}

struct ParseArgs(std::env::Args);

impl ParseArgs {
    fn new() -> ParseArgs {
        unimplemented!()
    }


    fn require_arg(&mut self) -> Result<String, ParseError> {
        match self.0.next() {
        }
    }
}

fn parse_args() -> Result<Frame, ParseError> {
    let mut args = ParseArgs::new();

    // skip the command name
    args.require_arg()?;

    let width_str = args.require_arg()?;
    let height_str = args.require_arg()?;
    args.require_no_args()?;
    let width = parse_u32(width_str)?;
    let height = parse_u32(height_str)?;

    Ok(Frame { width, height })
}

fn main() {
    println!("{:?}", parse_args());
}

Updating bouncy

This next bit should be done as a Cargo project, not with rustc. Let’s start a new empty project:

$ cargo new bouncy-args --bin
$ cd bouncy-args

Next, let’s get the old code and place it in src/main.rs. You can copy-paste manually, or run:

$ curl https://gist.githubusercontent.com/snoyberg/5307d493750d7b48c1c5281961bc31d0/raw/8f467e87f69a197095bda096cbbb71d8d813b1d7/main.rs > src/main.rs

Run cargo run and make sure it works. You can use Ctrl-C to kill the program.

We already wrote fully usable argument parsing code above. Instead of putting it in the same source file, let’s put it in its own file. In order to do so, we’re going to have to play with modules in Rust.

For convenience, you can view the full source code as a Gist. We need to put this in src/parse_args.rs:

$ curl https://gist.githubusercontent.com/snoyberg/568899dc3ae6c82e54809efe283e4473/raw/2ee261684f81745b21e571360b1c5f5d77b78fce/parse_args.rs > src/parse_args.rs

If you run cargo build now, it won’t even look at parse_args.rs. Don’t believe me? Add some invalid content to the top of that file and run cargo build again. Nothing happens, right? We need to tell the compiler that we’ve got another module in our project. We do that by modifying src/main.rs. Add the following line to the top of your file:

mod parse_args;

If you put in that invalid line before, running cargo build should now result in an error message. Perfect! Go ahead and get rid of that invalid line and make sure everything compiles and runs. We won’t be accepting command line arguments yet, but we’re getting closer.

Use it!

We’re currently getting some dead code warnings, since we aren’t using anything from the new module:

warning: struct is never constructed: `Frame`
 --> src/parse_args.rs:2:1
  |
2 | struct Frame {
  | ^^^^^^^^^^^^
  |
  = note: #[warn(dead_code)] on by default

warning: enum is never used: `ParseError`
 --> src/parse_args.rs:8:1
  |
8 | enum ParseError {
  | ^^^^^^^^^^^^^^^

warning: function is never used: `parse_args`
  --> src/parse_args.rs:14:1
   |
14 | fn parse_args() -> Result<Frame, ParseError> {
   | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Let’s fix that. To start off, add the following to the top of your main module, just to prove that we can, in fact, use our new module:

println!("{:?}", parse_args::parse_args());
return; // don't start the game, our output will disappear

Also, add a pub in front of the items we want to access from the main.rs file, namely:

  • struct Frame
  • enum ParseError
  • fn parse_args

Running this gets us:

$ cargo run
   Compiling bouncy-args v0.1.0 (/Users/michael/Desktop/tmp/bouncy-args)
warning: unreachable statement
   --> src/main.rs:115:5
    |
115 |     let mut game = Game::new();
    |     ^^^^^^^^^^^^^^^^^^^^^^^^^^^
    |
    = note: #[warn(unreachable_code)] on by default

warning: variable does not need to be mutable
   --> src/main.rs:115:9
    |
115 |     let mut game = Game::new();
    |         ----^^^^
    |         |
    |         help: remove this `mut`
    |
    = note: #[warn(unused_mut)] on by default

    Finished dev [unoptimized + debuginfo] target(s) in 0.67s
     Running `target/debug/bouncy-args`
Err(TooFewArgs)

It’s nice that we get an unreachable statement warning. It’s also a bit weird that game is no longer required to be mutable. Strange. But most importantly: our argument aprsing is working!

Let’s try to use this. We’ll modify the Game::new() method to accept a Frame as input:

impl Game {
    fn new(frame: Frame) -> Game {
        let ball = Ball {
            x: 2,
            y: 4,
            vert_dir: VertDir::Up,
            horiz_dir: HorizDir::Left,
        };
        Game {frame, ball}
    }

    ...
}

And now we can rewrite our main function as:

fn main () {
    match parse_args::parse_args() {
        Err(e) => {
            // prints to stderr instead of stdout
            eprintln!("Error parsing args: {:?}", e);
        },
        Ok(frame) => {
            let mut game = Game::new(frame);
            let sleep_duration = std::time::Duration::from_millis(33);
            loop {
                println!("{}", game);
                game.step();
                std::thread::sleep(sleep_duration);
            }
        }
    }
}

Mismatched types

We’re good, right? Not quite:

error[E0308]: mismatched types
   --> src/main.rs:114:38
    |
114 |             let mut game = Game::new(frame);
    |                                      ^^^^^ expected struct `Frame`, found struct `parse_args::Frame`
    |
    = note: expected type `Frame`
               found type `parse_args::Frame`

We now have two different definitions of Frame: in our parse_args module, and in main.rs. Let’s fix that. First, delete the Frame declaration in main.rs. Then add the following after our mod parse_args; statement:

use self::parse_args::Frame;

self says we’re finding a module that’s a child of the current module.

Public and private

Now everything will work, right? Wrong again! cargo build will vomit a bunch of these errors:

error[E0616]: field `height` of struct `parse_args::Frame` is private
  --> src/main.rs:85:23
   |
85 |         for row in 0..self.frame.height {
   |

By default, identifiers are private in Rust. In order to expose them from one module to another, you need to add the pub keyword. For example:

pub width: u32,

Go ahead and add pub as needed. Finally, if you run cargo run, you should see Error parsing args: TooFewArgs. And if you run cargo run 5 5, you should see a much smaller frame than before. Hurrah!

Exercise 4

What happens if you run cargo run 0 0? How about cargo run 1 1? Put in some better error handling in parse_args.

Exit code

Alright, one final irritation. Let’s provide some invalid arguments and inspect the exit code of the process:

$ cargo run 5
Error parsing args: TooFewArgs
$ echo $?
0

For those not familiar: a 0 exit code means everything went OK. That’s clearly not the case here! If we search the standard library, it seems the std::process::exit can be used to address this. Go ahead and try using that to solve the problem here.

However, we’ve got one more option: we can return a Result straight from main!

fn main () -> Result<(), self::parse_args::ParseError> {
    match parse_args::parse_args() {
        Err(e) => {
            return Err(e);
        },
        Ok(frame) => {
            let mut game = Game::new(frame);
            let sleep_duration = std::time::Duration::from_millis(33);
            loop {
                println!("{}", game);
                game.step();
                std::thread::sleep(sleep_duration);
            }
        }
    }
}

Exercise 5 Can you do something to clean up the nesting a bit here?

Better error handling

The error handling problem we had in the last lesson involved the call to top_bottom. I’ve already included a solution to that in the download of the code provided. Guess what I changed since last time and then check the code to confirm that you’re right.

If you’re following very closely, you may be surprised that there aren’t more warnings about unused Result values coming from other calls to write!. As far as I can tell, this is in fact a bug in the Rust compiler.

Still, it would be good practice to fix up those calls to write!. Take a stab at doing so.

Next time

We still didn’t fix our double buffering problem, we’ll get to that next time. We’re also going to introduce some more error handling from the standard library. And maybe we’ll get to play a bit more with iterators as well.

          Superpixel Guided Deep-Sparse-Representation Learning for Hyperspectral Image Classification      Cache   Translate Page      
This paper presents a new technique for hyperspectral image (HSI) classification by using superpixel guided deep-sparse-representation learning. The proposed technique constructs a hierarchical architecture by exploiting the sparse coding to learn the HSI representation. Specifically, a multiple-layer architecture using different superpixel maps is designed, where each superpixel map is generated by downsampling the superpixels gradually along with enlarged spatial regions for labeled samples. In each layer, sparse representation of pixels within every spatial region is computed to construct a histogram via the sum-pooling with $l_{1}$ normalization. Finally, the representations (features) learned from the multiple-layer network are aggregated and trained by a support vector machine classifier. The proposed technique has been evaluated over three public HSI data sets, including the Indian Pines image set, the Salinas image set, and the University of Pavia image set. Experiments show superior performance compared with the state-of-the-art methods.
          Effective Data Driven Coding Unit Size Decision Approaches for HEVC INTRA Coding      Cache   Translate Page      
High Efficiency Video Coding (HEVC) INTRA coding improves compression efficiency by adopting advanced coding technologies, such as multi-level quad-tree block partitioning and up to 35-mode INTRA prediction. However, it significantly increases the coding complexity, memory access, and power consumption, which goes against its widely applications, especially for ultra-high definition and/or mobile video applications. To tackle this problem, we propose effective data driven coding unit (CU) size decision approaches for HEVC INTRA coding, which consists of two stages of support vector machine-based fast INTRA CU size decision schemes at four CU decision layers. At the first stage classification, a three output classifier with offline learning is developed to early terminate the CU size decision or early skip checking the current CU depth. As for the samples that neither early skipped nor early terminated, the second stage of binary classification, which learns online from previous coded frames, is proposed to further refine the CU size decision. Representative features for the CU size decision are explored at different decision layers and stages of classifications. Finally, the optimal parameters derived from the training data are achieved to reasonably allocate complexity among different CU layers at given total rate-distortion degradation constraint. Extensive experiments show that the proposed overall algorithm can achieve 27.95%–80.53% and 52.48% on average complexity reduction for the CU size decision as compared with the original HM16.7 model. Meanwhile, the average Bjonteggard delta peak-signal-to-noise ratio degradation is only −0.08 dB, which is negligible. The overall performance of the proposed algorithm outperforms the state-of-the-art benchmark schemes.

背景

360企业安全威胁情报中心近期捕获到了一例使用Flash 0day漏洞配合微软Office文档发起的APT攻击案例,攻击使用的样本首次使用了无Flash文件内置技术(Office文档内不包含Flash实体文件)。我们在确认漏洞以后第一时间通知了厂商Adobe,成为国内第一个向厂商报告此攻击及相关漏洞的组织,Adobe在昨日发布的安全通告中致谢了360威胁情报中心。


Hacking Team卷土重来?CVE-2018-5002 Flash 0day漏洞APT攻击分析与关联

Adobe反馈确认漏洞存在并公开致谢

整个漏洞攻击过程高度工程化:攻击者将Loader(第一阶段用于下载Exploit的Flash文件)、Exploit(第二阶段漏洞利用代码)、Payload(第三阶段ShellCode)分别部署在服务器上,只有每一阶段的攻击/检测成功才会继续下载执行下一阶段的代码,这样导致还原整个攻击流程和漏洞利用代码变得非常困难。360威胁情报中心通过样本的特殊构造分析、大数据关联、域名分析,发现本次使用的相关漏洞攻击武器疑似与Hacking Team有关。

由于此漏洞及相应的攻击代码极有可能被黑产和其他APT团伙改造以后利用来执行大规模的攻击,构成现实的威胁,因此,360威胁情报中心提醒用户采取应对措施。

如下图所示漏洞的关键触发利用代码发生在replace函数中,漏洞触发成功后可以通过交换vector中的两个对象以转换为类型混淆来实现代码执行,函数执行前声明了两个SafeStr_5,SafeStr_7类型的对象实例,并将这两个对象实例作为参数交替传入函数SafeStr_61中,一共256个参数,SafeStr_5,SafeStr_7类型各占128个:

SafeStr_5类如下所示:

SafeStr_7类如下所示:

Jit代码中生成对应的SafeStr_5类实例:

最终进入SafeStr_61前生成的SafeStr_5,SafeStr_7类实例如下所示,其中前两个是全局声明的实例,后两个是replace中声明的实例,之后作为SafeStr_61参数传入:

进入SafeStr_61函数前:

SafeStr_61函数如下所示,首先创建了一个SafeStr_6的类实例(用于触发漏洞),及SafeStr_5,_SafeStr_7类型的vector,之后将参数交叉传入两个vector中:

接着开始vector赋值:

赋值之后如下所示:

漏洞成因

现在来看看用于触发漏洞的_SafeStr_6类实例,AS代码如下:


Hacking Team卷土重来?CVE-2018-5002 Flash 0day漏洞APT攻击分析与关联

可以看到,由于Flash解析器处理对应的Try-Catch代码块时没有合理处理好异常处理代码的作用范围,解析器误认为不会有代码可以执行到Catch语句内,因此没有对Catch中代码对应的字节码进行检测,而该函数中的li8(123456)操作由于会触发异常并被Catch捕获,这样由于对Catch代码块中的代码缺乏检查,那么代码中的字节码通过setlocal,getlocal操作就可以实现对栈上数据的非法修改,最终将栈上两个对象指针的位置进行的替换,从而转化为类型混淆来实现任意代码执行!

漏洞利用

再来看看触发漏洞的代码上下文,其中_SafeStr_6即为上图所示触发漏洞的类实例代码:


Hacking Team卷土重来?CVE-2018-5002 Flash 0day漏洞APT攻击分析与关联

如下所示可以看到对应SafeStr_5类型的vector中的一个对象的指针被修改为了SaftStr的对象指针,其寻址标记为0x1c1=449,即为上图中getlocal操作的变量:


Hacking Team卷土重来?CVE-2018-5002 Flash 0day漏洞APT攻击分析与关联

之后将SafeStr_7类型的vector中的一个对象的指针修改为了SaftSt_5r的对象指针:


Hacking Team卷土重来?CVE-2018-5002 Flash 0day漏洞APT攻击分析与关联

接着遍历SafeStr_5中的每个对象的m_p1成员变量,获取对应修改成SafeStr_7指针的成员:


Hacking Team卷土重来?CVE-2018-5002 Flash 0day漏洞APT攻击分析与关联

由于SafeStr_5对象被混淆成SafeStr_7,因此对该混淆的SafeStr_5对象的操作,实际上作用的是SafeStr_7的内存空间,此时通过设置SafeStr_5对象的m_p1变量,即可实现对SafeStr_7对象对应内存偏移的操作,而该偏移在SafeStr_7对象中指向了对应的SafeStr_5对象,此时相当于SafeStr_7.SafeStr_5.m_p1的操作受_SafeStr_5对象的m_p1对象的控制,从而实现指定地址读写,之后转化为任意代码执行:

溯源与关联 相似样本

结合该漏洞投递文件(Excel文档)插入Flash ActiveX控件的技巧(复合二进制bin+远程Flash加载),360威胁情报中心通过大数据关联到另外一个使用相同技巧的投递Flash漏洞利用的文档控件文件(MD5:5b92b7f4599f81145080aa5c3152dfd9):

其内置的用于加载远程Flash漏洞攻击的URL如下:

域名分析

该域名在2015年到2016年初用于下载多个SWF Payload文件:


Hacking Team卷土重来?CVE-2018-5002 Flash 0day漏洞APT攻击分析与关联

而该域名mynewsfeeds.info历史曾由 marchaopn@gmail.com 注册,在HackingTeam 2015年7月的泄露事件后,该域名做了隐私保护:


Hacking Team卷土重来?CVE-2018-5002 Flash 0day漏洞APT攻击分析与关联

结合360威胁情报平台,该域名也关联到CVE-2015-5119的漏洞利用样本,该漏洞同样也是Hacking Team泄露事件曝光的Flash 0day漏洞!


Hacking Team卷土重来?CVE-2018-5002 Flash 0day漏洞APT攻击分析与关联
域名为Hacking Team所属

其中 marchaopn@gmail.com 邮箱注册的签名证书正是Hacking Team所属:


Hacking Team卷土重来?CVE-2018-5002 Flash 0day漏洞APT攻击分析与关联

以及HackingTeam与客户的交流邮件中提到该域名和邮箱的信息:


Hacking Team卷土重来?CVE-2018-5002 Flash 0day漏洞APT攻击分析与关联

至此,360威胁情报中心通过本次泄露的0day漏洞利用样本的特殊构造方式找到一个高度相似的样本,而该样本则指向Hacking Team。

自Hacking Team泄露事件以来,其新的相关活动及其开发的间谍木马也被国外安全厂商和资讯网站多次披露,证明其并没有完全销声匿迹。

关于Hacking Team

360威胁情报中心结合多方面的关联,列举本次0day攻击事件和历史Hacking Team之间的一些对比:

l Hacking Team长期向多个情报机构或政府部门销售其网络间谍武器

l 在过去HackingTeam泄露资料中表明其对Flash 0day漏洞和利用技术有深厚的基础;而本次0day漏洞中的利用手法实现也是非常通用

l 本次0day漏洞的EXP制作方式和漏洞利用上也与HackingTeam过去的一些利用相似

防护建议

360威胁情报中心提醒各单位/企业用户,谨慎打开来源不明的文档,并尽快通过修复及升级地址下载安装最新版Adobe Flash Player,也可以安装360安全卫士/天擎等防病毒软件工具以尽可能降低风险。

          Restriction of domain of vector field      Cache   Translate Page      
I was trying to plot a field of normal vectors to a given implicit graph. What I got so far is: x, y = var('x y') f(x,y) = 2*x*y^3 g(x,y) = x^2*3*y^2 d = plot_vector_field((f(x,y)/sqrt(f(x,y)^2+g(x,y)^2),g(x,y)/sqrt(f(x,y)^2+g(x,y)^2)), (x,-5,5), (y,-5,5)) s = implicit_plot(x^2*y^3-1 , (x,-5,5), (y,-5,5)) show(s+d) And it works like a charm, however, is there a way to "restrict" a domain of plot_vector_field so it doesn't plot all the vectors in a given range, but only for point (x,y) lying on my graph? That is such points that x^2*y^3=1. I tried to just put it instead (y,-5,5) (in a y=(1/x^2)^(1/3) form), but it obviously doesn't work. Thx for any help as I'm new to Sage.

REMEMBER...A Tornado Watch means conditions are favorable for tornadoes and severe thunderstorms in and close to the watch area. Persons in these areas should be on the lookout for threatening weather conditions and listen for later statements and possible warnings.

&&

OTHER WATCH INFORMATION...CONTINUE...WW 423...WW 424...

AVIATION...Tornadoes and a few severe thunderstorms with hail surface and aloft to 0.5 inches. Extreme turbulence and surface wind gusts to 65 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 24045.






DAY SPONSOR





Hey, Bryan Carpenter here!!
I encourage you to pray before you vote.

A vote for Carpenter is going to help MAKE MACON SAFE AGAIN for all families and individuals old and young. We need to stop playing checkers and start playing chess with the issues that we are facing. We need to better educate ALL Macon County citizens about the dangers and consequences of Drugs, Bullying, and crimes in general.
I am determined to lower crime rates and am dedicated to bringing down the number of overdoses that are becoming more common. We have become complacent with the issues we are facing in Macon County.
I would also like to expand the K-9 unit in an effort to better utilize the potential that in my own experience know is there.
I wish to MAKE MACON SAFE AGAIN, and I would be grateful for the opportunity.

Your voice matters.
Your Vote is Your Voice.

Thank you and God Bless!!
CARPENTER for SHERIFF
MAKE MACON SAFE AGAIN!!!!!

Arc's electric Vector cafe racer throws the kitchen sink at cutting-edge tech and performance#source%3Dgooglier%2Ecom#https%3A%2F%2Fgooglier%2Ecom%2Fpage%2F%2F10000

If you want to know what the absolute state of the art in electric motorcycles is, Arc Vehicle reckons its Vector, just launched at EICMA, is a leap ahead. It's a hard-accelerating 120mph cafe racer with a monster 225-mile range, 30-minute charging, a matching haptic jacket and HUD helmet, and an eye-bleeding price tag.

          Decomposing functions of two variables      Cache   Translate Page      

A small part of Marc ten Bosch's guide to rotors and bivectors observes that:

it is possible to split a product (or any function that takes two arguments) into the sum of a part that does not change if we swap the arguments and one that does change, in the following way:

$$\begin{align} ab & =\frac12(ab+ab+ba−ba) \\&= \frac12(ab+ba)+\frac12(ab−ba)\end{align}$$

He means that in general we can decompose any as $$ f(a,b) = f_M(a, b) + f_N(a, b)$$

where $$\begin{align} f_M(a, b) & = \phantom{-} f_M(b, a) \\ f_N(a, b) & = - f_N(b, a) \end{align} $$

I never thought of this before. Compare Decomposing a function into even and odd parts.

          使用 Flink 解救多线程 Scala 应用      Cache   Translate Page      

要想应用能处理一天的大流量 api 的 traces, 自然直接的想法当然是找一个 MapReduce 的 Cluster 将一天的数据 map 成多份来进行处理, 最后 reduce 到一起来算 pXX.

 1: lazy val env = ExecutionEnvironment.getExecutionEnvironment // <= 1
 2: 
 3: lazy val rawSources = (ZipkinClient.datasources foldMap interp) unsafeRunSync ()
 4: 
 5: lazy val datasources =
 6:   env.fromCollection(rawSources.toList) // <= 2
 7: 
 8: lazy val program: DataSet[Vector[String]] = datasources
 9:   .faltMap(splitByHour _)        // <= 3
10:   .rebalance()                   // <= 4
11:   .map(source =>
12:     (ZipkinClient.fetchTraces(source) foldMap interp) unsafeRunSync ()) // <= 5
13:   .groupBy(_._1.endpoint.id)   // <= 6
14:   .reduce((s1, s2) => s1 |+| s2) // <= 7
15:   .map((traces: (DataSource, Vector[Trace])) =>
16:     (ZipkinClient.aggregate(traces) foldMap interp) unsafeRunSync ())  // <= 8
17:   .map((metrics: (Vector[LatencyMetrics], DataSource)) =>
18:     (CollectorService
19:       .writeMetrics(metrics._1, Vector(metrics._2)) foldMap interp) unsafeRunSync ())
20: 
  1. 当前执行环境, 例如跑在 cluster 上, 还是 jvm 里
  2. 初始化DataSet, DataSet是 flink batch job 的数据结果, DataSet 中的数据意味着可以并行跑在 cluster 中
  3. 拆分数据源, 类似大数据的 helloworld 计算字符个数例子, 你得先把句子拆成字符
  4. 负载均衡
  5. 合并, 类似于把同样的字符都归到一组, 方便下来计算
  6. reduce, 把每一组数据合并成一条数据
  7. 计算pXX
46709689-8d226a80-cc90-11e8-9f7c-5c110d48302c.png

有意思的是, 你是可以本地直接sbt run的, 此时 flink 的 cluster 会跑在 jvm 中.

但是 跑cluster 在单个 jvm 中会耗费大量资源, 所以最佳实践其实是根据运行环境, 选择不同的ExecutionEnvironment

lazy val env = envOrNone("EXECUTION_IN_LOCAL")
  .map(_ => ExecutionEnvironment.createCollectionsEnvironment)
  .getOrElse(ExecutionEnvironment.getExecutionEnvironment)

若是在本地运行, 比如跑功能测试或集成测试, 使用CollectionsEnvironment会省不少资源

          Jaguar Land Rover invierte en un nuevo fabricante de motos eléctricas      Cache   Translate Page      
jaguar-land-rover-arc-201851658_4.jpg

La nueva Arc Vector.

Jaguar Land Rover diversifica sus intereses en la industria de la movilidad gracias a su reciente inversión en el nuevo fabricante de motos eléctricas Arc, que precisamente acaba de desvelar su primer modelo en la feria EICMA de Milán 2018, que junto con Intermot en Colonia, es uno de los mayores eventos del mundo de las dos ruedas.

Esta inversión ha tenido lugar a través del fondo InMotion Ventures de Jaguar Land Rover y no ha sido de manera casual, ya que esta nueva compañía ha sido fundada precisamente por Mark Truman, un ex ejecutivo de Jaguar Land Rover.

Por el momento, ha sido presentado el primer prototipo de este modelo, aunque la marca ya ha confirmado el precio del modelo, ya que este dispone de su configuración definitiva (o al menos en gran medida), a pesar de contar con un aspecto más propio de un concept. Pues además de su estilizada silueta, de momento no monta los habituales y obligatorios retrovisores.

jaguar-land-rover-arc-201851658_6.jpg

La Arc Vector será fabricada en edición limitada.

La inversión de Jaguar Land Rover en una nueva start-up de motos eléctricas tiene mucho sentido, ya que la compañía británica está invirtiendo fuertemente en las nuevas tecnologías de movilidad eléctrica como solución o alternativa a las mecánicas tradicionales de combustión.

Si el segmento eléctrico del mundo del automóvil se encuentra en un momento álgido, con la llegada de numerosas nuevas marcas y modelos, el segmento eléctrico de las dos ruedas hace ya mucho tiempo que explotó y encontramos muchas más alternativas y protagonistas que en el sector del automóvil.

Al contrario que en el mundo de las 4 ruedas, las mecánicas eléctricas han tenido una sencilla implantación y rápida aceptación en la industria de la moto, ya que son vehículos que no son empleados habitualmente para recorrer largas distancias y que pueden ser estacionados prácticamente en cualquier sitio, lo que facilita enormemente la tarea de recarga. Por tamaño y peso no necesitan baterías de gran tamaño, a lo que se suma un precio evidentemente más contenido que el de un automóvil.

jaguar-land-rover-arc-201851658_5.jpg

103.000 € cada una.

La nueva Arc Vector será fabricada en formato de edición limitada, 355 unidades a 103.000 € la pieza. Aunque su nivel tecnológico justifica sobradamente el precio. Su mecánica eléctrica de 129 CV (95 kW) es curiosamente lo menos llamativo de su planteamiento técnico, pues tanto el chasis como el basculante trasero están realizados en fibra de carbono y su software interactúa con el usuario a través del casco y la chaqueta, especialmente desarrollados para esta moto. En el casco contamos con un sistema Head-Up Display y en la chaqueta se ofrecen avisos mediante vibración.

          Más de 15.000 sitios web que usan Wordpress han sido hackeados      Cache   Translate Page      

Worpress es un objetivo popular por que la mayoría de las webs lo usa para manejar y publicar su contenido. Esto de acuerdo a un informe por parte de Sucuri de sitios web comprometidos, hay un 78% de los 21.821 sitios estudiados que usan este gestor de contenidos.

Wordpress, con el paso del tiempo, continua a la cabeza con un amplio porcentaje de sitios web comprometidos, con una tasa del 74%.

El informe se centra en cuatro populares gestores de contenidos Open Source: se cubre también Joomla con un 14% de sitios comprometidos, Magento con un 5% y Drupal con un 2%.
Cuando se trata de software sin actualizar, un vector común para los ciberdelincuentes, el informe encontró que el 55% de las instalaciones de Wordpress estaban sin actualizar, mientras que Joomla, con un 86% de sitios sin actualizar, Drupal con un 84% y Magento con un 96%, continúan siendo líderes indiscutibles en sitios web sin actualizar o con versiones vulnerables.

Año tras año, Wordpress vio un decremento de un 1% en sitios web sin actualizar o infectados, mientras que Drupal tuvo un aumento de un 3%. Joomla y Magento siguen mostrando las versiones más desactualizadas de cada plataforma.

Las extensiones con poca seguridad dan a los cibercriminales un acceso inicial la mayor parte del tiempo. Sucuri encontró que, de media, las instalaciones de Wordpress tenían instaladas 12 plugins en cualquier momento. 

El top tres de vulnerabilidades de plugins de Wordpress que han contribuido al hackeo de los sitios con Wordpress: Gravity Forms, TimThumb y RevSlider.

Preocupantemente, solo el 18% de los sitios web infectados han sido metidos en una Blacklist por los principales motores de búsqueda y de protección de servicios web, dejando un 82% de los sitios web infectados sin marcar y presentando un potencial riesgo a los usuarios.

El esfuerzo más satisfactorio por bloquear estos sitios fue de Google Safe Browsing, con un 52% de sitios bloqueados. Norton Safeweb consiguió encontrar un 38%, mientras que McAfee SiteAdvisor encontró solo el 11% de sitios web hackeados.

          Relationship network structure and organizational competitiveness : evidence from BIM implementation practices in the construction industry      Cache   Translate Page      
Title: Relationship network structure and organizational competitiveness : evidence from BIM implementation practices in the construction industry Authors: Cao, DP; Li, H; Wang, GB; Luo, XC; Tan, D Abstract: Using the structural social capital perspective and a longitudinal data set on building information modeling (BIM) implementation practices in the construction industry in Shanghai, China, from 2007 to 2015, this study explores how the structural characteristics of the project-based interfirm collaboration networks within which design and construction organizations are embedded relate to their long-term organizational competitiveness. Hierarchical regression results provide evidence that after controlling for related organizational characteristics (including organizational experience in participating in large and influential projects, organizational ownership type, organization age, and organization size), degree and eigenvector centrality in relationship networks in an earlier period as a group significantly predicts organizational success in winning new project contracts in a later period. The results also provide evidence that due to their differences in BIM capability and innovation reputation, the competitiveness of designers and general contractors relate differently to the structure of their project-based interfirm relationship networks, with the competitiveness of designers more associated with the quantity of collaborative ties, whereas the competitiveness of general contractors relates more to the collaborative ties with high-status partners. As an exploratory effort at using longitudinal data to investigate the associations between interfirm relationship network structure and organizational competitiveness in the construction industry, this study contributes to the construction literature not only by validating the value of project-based interfirm relationships in generating social capital and thus relating to organizational competitiveness, but also by providing evidence for how the specific association between project-based relationship network structure and organizational competitiveness is contingent on the attributes of the network actors.

          Holographic RG flows and $AdS_5$ black strings from 5D half-maximal gauged supergravity      Cache   Translate Page      
arXiv:1811.01608

by: Dao, H.L.
Abstract:
We study five-dimensional $N=4$ gauged supergravity coupled to five vector multiplets with compact and non-compact gauge groups $U(1)\times SU(2)\times SU(2)$ and $U(1)\times SO(3,1)$. For $U(1)\times SU(2)\times SU(2)$ gauge group, we identify $N=4$ $AdS_5$ vacua with $U(1)\times SU(2)\times SU(2)$ and $U(1)\times SU(2)_{\textrm{diag}}$ symmetries and analytically construct the corresponding holographic RG flow interpolating between these two critical points. The flow describes a deformation of the dual $N=2$ SCFT driven by vacuum expaction values of dimension-two operators. In addition, we study $AdS_3\times S^2$ geometries dual to twisted compactifications of $N=2$ SCFTs with flavor symmetry $SU(2)$ and without flavor symmetry. We find a number of $AdS_3\times S^2$ solutions preserving eight supercharges for different twists from $U(1)\times U(1)\times U(1)$ and $U(1)\times U(1)_{\textrm{diag}}$ gauge fields. We numerically construct various RG flow solutions interpolating between $N=4$ $AdS_5$ ciritcal points and these $AdS_3\times S^2$ geometries in the IR. The solutions can also be interpreted as supersymmetric black strings in asymptotically $AdS_5$ space. These types of holographic solutions are also studied in non-compact $U(1)\times SO(3,1)$ gauge group. In this case, only one $N=4$ $AdS_5$ vacuum exists, and we give RG flows solutions from this $AdS_5$ to a singular geometry in the IR corresponding to an $N=2$ non-conformal field theory. An $AdS_3\times H^2$ solution together with an RG flow between this vacuum and the $N=4$ $AdS_5$ are also given for this gauge group. \end{abstract}

Results in the Lion Air Crash?



I'm receiving many emails and comments from people who participated in my research in response to the Lion Air accident. Now the FAA reports that the airspeed indicator was the problem. As we all know, technology is not infallible and components will break. Pilots should know how to fly.  

The question is, why couldn't they fly their aircraft? 



PILOT COMMENTS:

"Can we agree that any captain should be able to maintain aircraft control using standby instruments and power, safely fly an ILS on radar vectors, and land without incident..." 

"I'll be very surprised if there was something mechanically wrong about this airplane that made it un-flyable. I hate to think that it was pilot error, but that's exactly what I will expect to hear. I hope to be proven wrong."



My research is complete! 

Thanks to pilots worldwide who cared enough to assist in this research. I had 7490 pilots respond. While some surveys were incomplete, and some aircraft did not have autopilot, autothrust, or an EICAS, those were removed from the structural equation model (SEM), but all data was gathered to evaluate opinions. The final data analysis (SEM) was with 5661 surveys. I only needed 1599 to validate the model. 

What the results identified was that statistically aircraft and systems understanding has the greatest and positive impact on a pilots willingness to fly their aircraft. Statistically pilot training has the greatest impact on the level of understanding. That pilot training has a negative impact on pilots choice to manually fly their aircraft. Meaning the more training the pilot has, the the less the pilot is willing to fly their aircraft. Safety Culture has the greatest impact on pilot training. And finally when a mediating hypothesis was analyzed to see the impact of Safety Culture on Pilot Training and how that impacted a pilots willingness to manually fly, we found a negative relationship. I think my stats guru best explains this relationship with his statement: 


"Wow! Safety Culture is sucking 
the benefit out of pilot training!


Pilot error does not happen in isolation. If pilots are not given the tools to do the job, then what can we expect when the aircraft breaks?

I believe we found the underlying variables 
contributing to pilot error: 
Safety Culture and Pilot Training. 

Two things that are fixable. 
Hopefully that will be sooner than later.

My dissertation is in the final review phase now. As soon as it is approved and published, I will update the research website and provide a link to the full dissertation for everyone. Standby for a book from this research as well, that will be a gift to all participants! 

Thank you for caring enough to participate
in the interest of safety!

Enjoy the Journey!

“I am not actuality paid to do this. I accept this is a advantageous endeavour and I anticipate as architects we accept a lot to offer,” he said. “By agreeable a accessible chat about this, we can try to accept how the accessible ability brainstorm a bigger market.”



Wien, 1. Bezirk (the art of very renowned palace and museum buildings at the historic center of Vienna), Palais Erzherzog-Albrecht (Albertina), Albertinaplatz/Hanuschgasse – architectural design floor plans | architectural design floor plans

Dreessen’s proposed plan would be phased in gradually, starting with barring vehicular admission to ByWard Bazaar Square and William Street, which run beside the bazaar building.

York, Clarence and George streets would additionally lose their on-street parking, leaving more amplitude for pedestrians and cyclists. The streets would be redesigned into traffic-calmed “woonerfs” — where cars, cyclists and pedestrians allotment the aforementioned space.

If that succeeds, he proposes authoritative those changes permanent, abolition the parking barn on York Street, creating a multi-floor underground parking barn instead, and authoritative York Artery a woonerf, too.

“[The parking garage] really sticks out from the band of all the added barrio on York Street,” he said. “We acquiesce a parking barn to boss the skyline.”​

The burghal is accomplishing a analysis of the ByWard Market belt and has afresh invested in overhauls of the George Artery and York Artery plazas.

          En San Pedro, tres casos sospechosos de dengue      Cache   Translate Page      

Hay tres casos sospechosos de contagio de dengue en San Pedro, confirmó la titular de la Jurisdicción Sanitaria número siete, Rocío Quiroz Flores.

Agregó que en el municipio hay seis vegas (brazos del río) que durante la temporada de lluvia se acumula agua, además se utilizan para la descarga de aguas residuales, debido a los problemas que se tienen con la red de drenaje, por lo que se crean las condiciones para la proliferación del mosquito transmisor del dengue.

"Nosotros tenemos que estarlas tratando, es decir aplicar abate y fumigar para evitar que se reproduzca el vector (mosquito)", afirmó

La doctora mencionó que se aplicó el Espinosad, que es el químico que resultó más efectivo para terminar con la larva o los huevecillos y las aplicaciones se hacen en un periodo de 8 a 10 días, hasta matar completamente los mosquitos.

Agregó que también personal de algunos departamentos acuden a desaguar las vegas, pero subrayó que la parte más difícil para contrarrestar la proliferación del mosquito, es crear conciencia en la ciudadanía para que se abstengan de arrojar basura, que también contribuye a la proliferación del mosco.

En relación al probable contagio de las tres personas, dijo que, todavía no les entregan los resultados de los exámenes de laboratorio de Saltillo, para su confirmación.

"De esos casos las personas están en sus domicilios, con tratamiento y hasta ahorita no hemos tenido casos disparados (sic), aún y con la situación de como estaba en la vegas, con las lluvias y pues se sigue vertiendo el agua del drenaje, estamos al pendiente", finalizó la titular de la jurisdicción sanitaria.

A la espera

Esperan resultados de el laboratorio de Saltillo para confirmar el contagio de tres personas de dengue.

=> La Secretaría de Salud cataloga a San Pedro como "foco rojo", en ese padecimiento.

=> Mientras que en la Jurisdicción, afirman que no se han "disparado" el número de casos

How house design affects malaria mosquito density, temperature, and relative humidity: an experimental study in rural Gambia.

Lancet Planet Health. 2018 Nov;2(11):e498-e508

Authors: Jatta E, Jawara M, Bradley J, Jeffries D, Kandeh B, Knudsen JB, Wilson AL, Pinder M, D'Alessandro U, Lindsay SW

Abstract
INTRODUCTION: Unprecedented improvements in housing are occurring across much of rural sub-Saharan Africa, but the consequences of these changes on malaria transmission remain poorly explored. We examined how different typologies of rural housing affect mosquito house entry and indoor climate.
METHODS: Five typologies of mud-block houses were constructed in rural Gambia: four were traditional designs with poorly fitted doors and one was a novel design with gable windows to improve ventilation. In each house, one male volunteer slept under a bednet and mosquitoes were collected indoors with a light trap. Typologies were rotated between houses weekly. Indoor conditions were monitored with data loggers and the perceived comfort of sleepers recorded with questionnaires. We used pyschrometric modelling to quantify the comfort of the indoor climate using the logger data. Primary measurements were mean number of Anopheles gambiae and mean temperature for each house typology.
FINDINGS: In thatched-roofed houses, closing the eaves reduced A gambiae house entry by 94% (95% CI 89-97) but increased the temperature compared with thatched-roofed houses with open eaves. In houses with closed eaves, those with metal roofs had more A gambiae, were hotter (1·5°C hotter [95% CI 1·3-1·7]) between 2100h and 2300 h, and had 25% higher concentrations of carbon dioxide (211·1 ppm higher [117·8-304·6]) than those with thatched roofs. In metal-roofed houses with closed eaves, mosquito house entry was reduced by 96% (91-98) by well fitted screened doors. Improved ventilation of metal-roofed houses made them as cool as thatched houses with open eaves. Metal-roofed houses with closed eaves were considered more uncomfortable than thatched ones with closed eaves. In metal-roofed houses, ventilated houses were more comfortable than unventilated houses before midnight, when people retired to bed.
INTERPRETATION: Closing the eaves reduced vector entry in thatched houses but increased entry in metal-roofed houses. Metal-roofed houses with closed eaves were, however, protected against malaria vectors by well fitted screened doors and were made comfortable by increasing ventilation. House designs that exclude mosquitoes and are comfortable to live in should be a priority in sub-Saharan Africa.

          Caleap (AIICB): În realitate, aproximativ 7 milioane de români sunt plecaţi în străinătate; nu cred că se vor mai întoarce 10%      Cache   Translate Page      
Numărul românilor plecaţi în străinătate este, în realitate, de aproximativ 7 milioane, din care nu cred că se vor mai întoarce 10% în România, a declarat, miercuri, Cezar Caleap, director executiv al Asociaţiei Internaţionale a Întreprinderilor Creative din Belgia (AIICB), în cadrul unui workshop cu tema "Bruxelles şi calea spre succes". "Interesul nostru (al antreprenorilor, n.r.) este să ieşim din şablonul unei comunicări oficiale, iar eu, din punctul meu de vedere, cred că e nevoie să comunicăm deschis, să interacţionăm. Belgia poate fi pentru noi un prim proiect pe care să-l creionăm. Sunt convins că există multe alte zone de interes din punct de vedere al business-ului. E adevărat că Belgia sau Bruxelles-ul nu sunt atât de ofertante din punct de vedere al business-ului, dar ce vreau să spun este că avem acolo diaspora românească, este prima comunitate după belgieni. Nu ştiu dacă este o bucurie. Diaspora românească este prima comunitate şi în Italia, şi în Spania, şi în Anglia şi începe să nu mai fie în România. Ce ştiu este că, în realitate, avem aproape 7 milioane de români plecaţi în străinătate, din care nu cred că se vor mai întoarce 10% în România, să fim conştienţi de asta. În statisticile de la Ministerul de Externe am fost surprins să văd că avem români în Japonia, America de Sud şi vorbesc despre cifre reale, ale celor cu rezidenţă, în număr de 5 milioane, lucru care nu se comunică la noi corect. De asemenea, cel puţin două milioane de români sunt într-un du-te vino", a spus Caleap. La rândul său, Viorel Stoica, preşedintele executiv al Asociaţiei Internaţionale a Întreprinderilor Creative din Belgia, a menţionat că, la ora actuală, în Belgia, comunitatea românească numără 170.000 de persoane, din care 48.000 în capitala Bruxelles. "În Belgia vorbim despre o comunitate de români de 170.000 de persoane. Există acolo foarte multe familii mixte. Eu sunt mai optimist şi spun că din totalul românilor plecaţi în străinătate se vor întoarce 50% în ţară, dacă ştim să-i atragem, dacă ştim să ne plimbăm prin satele din Belgia şi să construim în România astfel de sate. Avem foarte mulţi români care sunt în Belgia şi trebuie să ştim să folosim acest suport financiar. Acum, Asociaţia Întreprinderilor Creative din Belgia sădeşte, iar roadele vor apărea în timp", a menţionat Stoica. În privinţa rolului pe care capitala Belgiei îl poate avea asupra viitoarelor iniţative creative, Costin Lianu, general manager al USH Pro Business, a subliniat faptul că Bruxelles-ul nu are numai un renume de capitală europeană, ci este şi locul se pot dezvolta foarte multe afaceri şi unde sunt reprezentate interesele. "Bruxelles-ul nu este prin el însuşi o piaţă extrem de dezvoltată, o concentrare pentru distribuitori pe diverse pieţe care ne pot duce spre canale de distribuţie europene, cum mulţi exportatori şi firme din România caută. În acelaşi timp, Bruxelles are o vocaţie de loc în care se pot reprezenta interesele şi poate crea acel lobby sau branding necesar pentru ca producătorii să îşi poată dezvolta afacerile. Consider că, în momentul de faţă, capitala Belgiei este puţin valorificată din punct de vedere a reprezentării intereselor mediilor de afaceri din România. Principalul atu al Bruxelles-ului este concentrarea mare de experţi, diplomaţi şi persoane care pot fi vectori pentru prezentarea şi dezvoltarea afacerii", a susţinut Lianu. Asociaţia Internaţională a Întreprinderilor Creative din Belgia ((L&#39;Association Internationale des Entreprises Créatives) a fost înfiinţată în luna august 2018 şi îşi propune ca anul viitor să organizeze, la Bruxelles, în perioada 22 - 24 februarie, o expoziţie de produse şi servicii, care sunt aşteptate circa 150 de firme din România şi alte aproape 150 de firme ale românilor din Belgia, alături de companii belgiene. Asociaţia îşi propune să devină un centru de reprezentare cu antreprenorii români care vor să se dezvolte sau au dezvoltat deja afaceri în Belgia. De asemenea, un alt plan al noii Asociaţii este să creeze în Belgia un magazin românesc de tip "ancoră" care să deservească mai multe firme din România.

          Ensō: A PS Vita bootloader exploit      Cache   Translate Page      

HENkaku Ensō, the first ever permanent jailbreak (also known as a custom firmware) for all PlayStation Vita devices running home menu version 3.6 was released by molecule on 2017-29-07.

In this blog post I’ll explain how I found the vulnerability and how the exploit was developed and debugged. The rest, i.e. actually loading the jailbroken CFW, is covered in this follow-up article by Yifan Lu.

You might notice how in the linked post Yifan refers to Ensō as “one of the first vulnerabilities we found was in the bootloader”. This is an obvious lie, I found this vulnerability all by myself, trust me. Now that we’re clear on that, please carry on reading.

Introduction

Bootloaders are a great target to exploit. Taking over the boot process early on lets us execute our code before the system has finished initializing, allowing for much more control compared to a more traditional exploit chain such as HENkaku. In some cases it might be possible to create a future-proof exploit, i.e. being able to keep the exploit working and having latest firmware’s features (for example, support for newer games) at the same time. Unfortunately, this is not the case with Vita and Ensō, but hacking the bootloader is still worth it.

Terminology

  • ASLR: Address space layout randomization. The important thing here is that Vita bootloader doesn’t have it, so a memory corruption can be turned into an exploit fairly easily.
  • ARM: The main Vita processor is a quad core Cortex-A9. In addition, Vita has a security processor, which is a Toshiba MeP, a MIPS processor used for PSP compatibility, a bunch of PowerVR GPU cores using two custom assembly languages, syscon: an external Renesas chip, and more.
  • TrustZone: The CPU supports ARM TrustZone technology, which isolates so-called “trusted” code from the rest of the system. For the purposes of this article, however, you just need to know that it is somewhat of a one side barrier between trusted (aka secure) and untrusted code, allowing trusted code to gain control over untrusted but not vice-versa. Execution starts from secure mode and transfers to non-secure.
  • SBL: secure boot loader. This is the first code that runs on ARM. It sets up NSBL (see below) and transfers control to it after dropping out of the secure mode.
  • NSBL: non-secure boot loader. This is the first code that runs on ARM in non-secure mode (outside of TrustZone).
  • eMMC: This is the primary persistent storage on Vita. It’s where the operating system, bootloaders, and system data are all stored.

Sidenote: Unlike most embedded devices, Vita implements device unique eMMC block level encryption that is transparent to the processor. This means that if you dump the data from the chip (or sniff data lines), you’ll get encrypted data. At the same time, Vita operating system will always see the decrypted data, even at the most privileged level of its operation. One consequence of this is that you have to dump and restore the data the same way. For example, if you dump the data using an eMMC adapter, you can’t restore it in software as it will have a layer of encryption unaccounted for, and vice-versa.

  • Block: data is read from eMMC in blocks. The physical block size is 0x200 bytes, so reading a single block from eMMC means reading 512 bytes.

Attack vectors

SBL is the first code to execute on the ARM processor. Unfortunately, it takes no controlled input whatsoever, so it is not possible to attack in any way.

The obvious next target is NSBL. Because it reads and loads the kernel, it is also the first code running on ARM where we can affect the execution flow. An example of affecting its execution flow is removing all kernel modules from os0:, which would turn your Vita into a useless paperweight.

The very first step of loading kernel modules is reading and parsing the filesystem they are stored on. Let’s dig deeper into the process.

Partition table

The eMMC storage on Vita is divided into multiple partitions that have different responsibilities. In this post I’ll only look at os0:, however, if you’re interested in the full list, check out the wiki article on the subject.

A partition table stores partitions’ locations, sizes and other miscellaneous information. For example, on Vita we have os0: and vs0: partitions; on Linux you may have /dev/sda1 and /dev/sda2. The partition table is usually stored in the first blocks of the physical device. Common partition table formats used on PC are MBR (also called DOS) and GPT.

On Vita, however, a custom partition table format is used. The first physical block, i.e. bytes [0x000; 0x200), contain the partition table. The structure is documented on the wiki. While not completely accurate, I’ll refer to this block as MBR throughout this article. In pseudocode Vita’s MBR would be:

typedef struct {
    uint32_t off;
    uint32_t sz;
    uint8_t code;
    uint8_t type;
    uint8_t active;
    uint32_t flags;
    uint16_t unk;
} __attribute__((packed)) partition_t;    // Size = 17 bytes

typedef struct {
    char magic[0x20];
    uint32_t version;
    uint32_t device_size;
    char unk1[0x28];
    partition_t partitions[0x10];
    char unk2[0x5E];
    char unk3[0x10 * 4];
    uint16_t sig;
} __attribute__((packed)) master_block_t;  // Size = 512 bytes

Vita supports up to 16 partitions and each partition entry is 17 bytes. For example:

Yellow: idstorage; Cyan: active SLB2; Pink: inactive SLB2.

Note that the partition table is not aware of partitions’ contents. As such, there is a disconnect between for example how large a partition is in the partition table and how large the target filesystem is. The filesystem itself also isn’t aware of where it’s placed on the disk, so all offsets are relative to its first block.

Some important partitions, for example, os0: where kernel modules and other system files are stored, have a shadow copy. This is done so that a system update doesn’t brick your console if you lose power in the middle of it. The updater first overwrites the inactive os0 with the new version and then flips the active bit around. Since flipping the active bit is very fast, it is very unlikely that you’d lose power at that exact millisecond.

FAT file system

The os0: partition uses the FAT file system. The first block of the partition, called FAT boot sector, stores system data such as number of bytes per sector, number of sectors per head and number of heads per cylinder. For flash memory, like Vita uses, the concepts of cyliders or heads don’t make sense, but they are still present.

Normally, the boot sector looks like this:

The vulnerability

At offset 0xB in the FAT boot sector there is a 16-bit value called BytesPerSector (marked in red). On Vita it is set to 0x200 to match the physical sector size.

The function that parses the boot sector is located at 0x5101FD18 in 3.60 NSBL. At some point it reads the field:

fat_bytes_per_sector = *(unsigned __int16 *)&fat_cache_2.magic[0xB];
fat_bytes_per_sector_minus_1 = *(unsigned __int16 *)&fat_cache_2.magic[0xB] - 1;

And then there’s a check at the end of the function:

if ( fat_bytes_per_sector_minus_1 >= 0x200 )
  return 0x803FF003;

It seems that if we set BytesPerSector to a large value, e.g. 0x400 it would error out and Vita would refuse to boot.

Sidenote: Notice how it compares not the original BytesPerSector, but rather a calculated BytesPerSector - 1. This is likely an optimization made by the compiler. The original code probably looked like:

if (BytesPerSector == 0 || BytesPerSector > 0x200) { error out }

In our case, if BytesPerSector is zero, then BytesPerSector - 1 would be 0xFFFFFFFF, and would also fail the optimized check.

But let’s look deeper. The function with the check described above, which I’m going to call fat_buggy_func, is called from another function located at 0x5100124C that I’ll name setup_emmc. This one does:

// ...
v8 = &os0_dev;
result = fat_buggy_func(v8, 0x110000, v9, v10);
// ...
return result;

Further, setup_emmc itself is called from the function responsible for loading the modules, located at 0x5100163C:

// ...
cpu_barrier_start2(0);
if ( !get_cpu_aff() ) { // if executed on CPU0
  setup_emmc();
// ...

Oops! Turns out, this one doesn’t use the return value at all! Therefore, NSBL will proceed even though BytesPerSector is now 0x400.

Since fat_buggy_func had returned early with an error, some code inside it did not execute and some variables were left uninitialized. Fortunatelly, it doesn’t matter for our exploit.

Looking for code that would use our BytesPerSector I found a function at 0x5101F56C. This is what I’ll call exploited_fat_func. It has the following loop:

while ( 1 )
{
  if ( *v73 )
  {
    v12 = (*v73)(dword_511673A0, v69, blocks_per_sector >> 9, temp_store);
  }
  else
  {
    raw_block_read = *(int (__fastcall **)(_DWORD, int, unsigned int, char *))(v68 + 84);
    if ( !raw_block_read )
      goto LABEL_42;
    // we'll exploit this call below
    v12 = raw_block_read(*(_DWORD *)(v68 + 88), v69, blocks_per_sector >> 9, temp_store);
  }
  if ( v12 < 0 )
    goto LABEL_42;
  blocks_per_sector = *(_DWORD *)(v68 + 80);
  v13 = blocks_per_sector >> 5;
  if ( blocks_per_sector >> 5 )
    break;
LABEL_49:
  if ( ++v69 == v77 )
  {
    v8 = v11;
    goto LABEL_51;
  }
}

raw_block_read is a function pointer. It reads 0x200-sized blocks from the flash. blocks_per_sector >> 9 is equivalent to blocks_per_sector / 0x200, so it calculates how many blocks a sector is made of and reads that much from the flash memory.

The data is read into temp_store which is a global array 0x200 bytes in size. Now that we’ve managed to set blocks_per_sector to 0x400, it will overflow the array and corrupt the data after it.

The function pointer, raw_block_read, is loaded from v68 + 84. v68 is a pointer to os0_dev, which is also a global variable. It is located at 0x51167784, while temp_store is located at 0x511671A0. As such, we can corrupt the whole structure including this function pointer by setting blocks_per_sector to e.g. 0x800.

Exploit process

Now if the loop executes at least twice, on the first iteration it will corrupt the function pointer and on the second it will execute our code!

Debugging the exploit

Since any mistake here would result in a permanently bricked console, testing the exploit requires a modified Vita system so that one can restore eMMC contents at any time. At the time I didn’t have access to one, so the initial testing was done on QEMU.

By mapping bootloader image to 0x51000000, stubbing some functions (e.g. changing raw_block_read to read from file instead of implementing the HW interface), we created a test environment that allowed for rapid prototyping of the exploit.

Sidenote: Vita has 4 ARM cores. You can think of it as 4 separate CPUs. When the non-secure world starts, all CPUs start executing NSBL from the first instruction at the same time.

The cpu_barrier_start and cpu_barrier_end functions make sure that different CPUs execute same code sequentially. For example, in pseudocode:

cpu_barrier_start()
some_function()
cpu_barrier_end()

some_function() would be called sequentially by CPU0, CPU1, CPU2, CPU3, and only a single CPU would execute it at a time.

However, there is a bug in these barrier functions. Can you find it? This bug never shows on real hardware, but on old QEMU it prevents us from going past the first barrier so I had to fix it. Here’s the code listing, including supporting functions.

What’s the best part about using QEMU? You get console output!

QEMU window

What’s even better? You get debugging too!

gdb window

It turns out that in addition to having no ASLR in the bootloader, it is also entirely mapped as RWX. At this point developing the rest of the exploit was a breeze. What I did was overwrite the function pointer with a pointer to the global buffer, then write our shellcode to the buffer. Soon I had a payload which did a printf (that you cannot see on real hardware) and another one which blinked the PS button led.

Exploit attempt 01

Testing on real hardware

I had davee help me test the payload on a real Vita which had a eMMC hardware mod implemented. Unfortunately, it did not work at all. The reason for that is that ARM is not instruction/data cache coherent. (which I really should’ve remembered but at the time was blinded by the excitement of having a boot time hack)

What that means is that you cannot just write code into RWX memory and jump into it – you have to writeback the data cache first and then flush the instruction cache. So even though there’s RWX memory and we have our code already there, we still have to implement a ROP chain to perform cache maintenance.

Fortunately, we have all the pieces already. We control the function pointer and also R0 (it is the first argument to the function, it’s loaded from v68 + 88 and we control data around v68). We also have our controlled data put at a known address, and NSBL has all the gadgets and cache maintenance functions we might ever need.

Exploit attempt 02

To kick off the ROP chain I used this LDM gadget that loads both PC and SP from R0 as a pivot:

0x51014f10 e890b672 ldm r0, {r1, r4, r5, r6, r9, sl, ip, sp, pc}

From there, the ROP chain calls data cache clean (also known as writeback on other architectures), instruction cache flush, and finally jumps to the payload. You can find the full ROP chain here.

Payload

Ultimately, we want Vita to boot. However, since 0x800 bytes of data section are corrupted, the bootloader now is in a weird state with a completely broken os0_dev. Not only is it overwritten, but there’s no actual “filesystem” in place, it’s just our hacked up boot sector. We have to restore it before the boot can proceed:

  1. Patch the partition read function. We redirect block 0 to block 1 and in Ensō installer write the original pristine partition table into block 1. We need to do this so that the rest of the system doesn’t use our broken os0 “partition”.

Sidenote: We’re redirecting all reads of block 0 to block 1, but not writes. This means if you read block 0 and then write it back, you’ll implicitly uninstall Ensō. One tool that does this is Sony firmware updater (when flipping active os0 bit), which is also the reason we’ve designed Ensō this way.

However, this results in unintutive and dangerous interactions. For example, if you uninstall Ensō, we restore block 0 and overwrite other blocks used by our payload (including block 1) with empty data. But this also means that if the system tries to read block 0 after the uninstall, it’d get garbage data. Which is why it’s important that any modification to Ensō operation is followed by a reboot.

eMMC state vs what the kernel sees

Another failure of our design is that we didn’t provide a way to detect whether Ensō is installed. To make sure we don’t uninstall what’s not installed, the original uninstaller checked block 1 to see if it’s a valid MBR. It then read it and wrote it to block 0. However, if instead of uninstalling Ensō through the application you upgraded your firmware and “implicitly” got rid of it, the block 1 would remain. At this point if you run the uninstaller again (never mind that there’s no reason to do that as Ensō is no longer installed), even if not on 3.60 anymore, it would see valid MBR in block 1, overwrite your real MBR with it and likely brick your console.

Why this bricked

The solution is simple yet perfect – just get rid of that logic. Instead, always read block 0 and write it back.

  1. Reinitialize os0_dev so that it points to the correct partition and can be read from.
  2. Restore the data we accidentally corrupted with the buffer overflow.

Sidenote: This was one of the show-stoppers during the development of Ensō. One of the more important things we overwrite is sysroot which stores a ton of console-specific information. Initially, I developed the exploit on an earlier firmware where the different layout of NSBL ensured that nothing important is overwritten. On 3.60, however, we were stuck. Without a valid sysroot the console wouldn’t get very far in the boot process. The sysroot is also generated by an earlier boot stage, so there’s no way to recreate it. Fortunately, Yifan has found out that just before our vulnerable code is executed, the sysroot is copied by NSBL to a different place, and we can easily copy it back. Crisis averted!

  1. Load the larger payload. It does some magic to make sure HENkaku and taihen are loaded on boot. Yifan wrote that one so it’s probably full of bugs, but you can check out his writeup here if you care.
  2. Restore the context and resume boot, as if nothing had happened.

When we enter the executable payload, sp is somewhere inside our ROP chain (which is somewhere inside the data section, near the os0_dev structure). The very first thing the payload does is change sp to unused scratch area so that our C code doesn’t turn the data section into garbage.

Once we’re done with our hooking and patching though, we want Vita to continue its boot process. But remember that our payload got called in the first place because of the exploit – while executing an NSBL function the bootloader just jumped into our code! And there’s nowhere for our payload to return, as it’s using a separate stack set up by the pivot gadget.

There’re multiple solutions to this problem. For example, one could reimplement NSBL from scratch, or clean it up and trigger a soft-reboot. However, I’ve solved this issue by “restarting” the exploited_fat_func from the point we took over. I did that by restoring corrupted registers to their original values, including the original SP. It is similar to how setjmp and longjmp work, although I never bothered to explicitly save the original values, instead, they are recalculated. Here’s the code:

// restore context and resume boot
uint32_t *sp = *(uint32_t**)(0x51030100 + 0x220); // sp top for core 0
uint32_t *old_sp = sp - 0x11d;
// r0: 0x51167784 os0_dev
// r1: 0xfffffffe
// r2: sp - 0x110
// r3: 0
__asm__ volatile (
    "movw r0, #0x7784\n"
    "movt r0, #0x5116\n"
    "movw r1, #0xfffe\n"
    "movt r1, #0xffff\n"
    "mov r2, %0\n"
    "mov r3, #0\n"
    "mov sp, %1\n"
    "mov r4, %2\n"
    "bx r4\n"
    :
    : "r" (sp - 0x110), "r" (old_sp), "r" (0x5101F571)
    : "r0", "r1", "r2", "r3", "r4"
);

And from that point the boot continues normally and your Vita boots straight into HENkaku. Isn’t that great?

Bricks & lessons learned

There were two bricks during the private testing period and ~3 bricks because of the uninstaller bug described above. Unfortunately, we didn’t learn about the brick bug fast enough because people reported it on various forums instead of using our issue tracker (which is also our fault as we didn’t provide a clearly visible URL pointing to it).

Having said that, with over 270,000 downloads as reported by GitHub, I consider this release a huge success. At the same time, there are still things we could’ve done better. The obvious one is lack of a way to detect whether Ensō is installed, but there’re also other ideas I’ve been thinking about such as auto-uploading installer logs to our server, checking for installer updates at startup, and a user-friendly way to update taiHEN and HENkaku kernel modules.

Hopefully, our experience will serve as a great example of why dangerous code like the installer cannot be too safe. While we did have a ton of safety checks, including reading back blocks after they are written and checking they’re intact, we still missed a bug that resulted in a few bricks. Fortunately, as it is fixed now, there are no more bugs left and Ensō installer is the first ever example of bug-free C code!

How Sony fixed it

The vulnerability was fixed by Sony in firmware 3.67, which means firmwares 3.60 to 3.65 (and potentially everything before 3.60) are exploitable. They added the missing return value check and a panic call inside setup_emmc after fat_buggy_func is called.

result = fat_buggy_func(/* ... */);
os0_ret = result;
// ...
if ( os0_ret )
  panic(/* ... */);

In addition, they sprinkled BytesPerSector checks over various read-related functions, so even if by some miracle one manages to bypass the panic call, the moment e.g. sceIoRead is called, your Vita would explode.

Epilogue

The vulnerability here conceptually is way simpler than the HENkaku one, just a trivial global buffer overflow. The lack of the usual mitigations (ASLR, read-only code, etc) also makes it really easy to exploit. On the other hand, there’s way less attack surface (i.e. zero syscalls) compared to the whole kernel and you kind of need to be good at soldering to attempt the hardware mod.

Existence of another vulnerability in NSBL is mathematically impossible in this new paradigm. In a sense, we got very lucky with the Ensō one as other than this really obvious issue (sabotage by a disgruntled Sony employee? ヽ(°〇°)ノ) there’s not much left in NSBL.

That’s all for today, thanks for reading!

Look out for the cyber threats hiding in your backups

Spending on security technology continues to soar. Nevertheless, data breaches and cyberattacks continue to make headlines at an incredible rate, with no relief in sight. The Online Trust Alliance reported that attacks in 2017 came from a myriad of vectors, such as phishing and ransomware, and that the number of attacks doubled to nearly 160,000 incidents per year over 2016. What’s worse, estimates for the number of unreported attacks exceed 350,000 annually.

While enterprises typically dominate the headlines, organizations of all sizes are affected by cyber incidents. A recent Ponemon study showed that two-thirds of small and mid-sized businesses reported that threats evaded their intrusion detection systems, and more than half of the companies said they were attacked by ransomware more than twice during the last year. There is no dispute that the number of vulnerable endpoints and the complexity of threats will continue to increase, and limited IT budgets and overstretched staff will remain an industry-wide problem. It’s clear that companies need to adopt new approaches to stay ahead of cyberattacks.

Traditional approaches aren’t enough

Firewalls and antivirus solutions are the norm in most IT shops, and they do thwart security attacks daily. Despite being very widely deployed, industry trends clearly show the need for more innovative approaches to threat detection.

Larger organizations have the resources to implement security incident & event management (SIEM) solutions, which are effective in collecting vast amounts of data from endpoints. Arrays of sensors can be integrated to provide rich and comprehensive security data for many types of cyber analytics. But big data platforms are complex to deploy and manage, and even the most advanced IT shops admit to not being able to keep up with the sheer volume of flags and false positives. Unfortunately, hidden in the sea of alerts are numerous threats that do get through, untriaged and undetected.

Whether or not a company has the resources for the most advanced cybersecurity tools and specialized personnel to support them, the fact remains that traditional solutions are not stopping threats from compromising critical network systems.

Gaps in the armor

Backup and disaster recovery systems are the go-to resources as insurance policies to protect against cyberattacks. Successful recovery from the last known good configuration is a reasonable and sound approach, but this assumes knowing exactly when the attack occurred, as well as discipline with ongoing backup testing. A 2018 benchmark study sponsored by IBM revealed that a mean time to identify a data breach incident climbed to a staggering 197 days with another 69 days to contain it. Backups are being contaminated during this lengthy timeframe. Thus, the recovery process following a cyber incident will not only be highly labor-intensive but also a protracted affair, if it is even possible at all.

Compounding matters, breaches rarely remain confined and often spread across a corporate network, compromising a variety of systems and databases, making the recovery effort even more complex. As malware continues to increase in sophistication, the level of manual effort required to unravel the intricate cybersecurity maze and restore all system components of a production environment can be immense.

Looking forward

In the future, we will see intelligent and automated tools that use granular backup and replication data sets to continuously detect latent security breaches, irregular behavior and patterns or other unusual backup attributes that may pose a risk to a quick recovery. Offline backup and replication files and their metadata are an untapped wealth of context-rich cybersecurity data, which opens a new door to proactively identifying cyber threats without impacting production workloads. With the right tools, organizations of all sizes could leverage this data to improve their security posture and decrease the labor-intensive manual effort currently required in recovery efforts.

Soon, security fingerprinting, data transformation, machine learning and advanced analytics will all be brought to bear to automatically analyze backup and replication data for cybersecurity issues in near real-time. By integrating with threat intelligence feeds, verified cyber infections can be readily detected and confirmed. Malware and other anomalous behavior can be surfaced and resolved long before the backups or replicas are needed following a disaster. These next-generation cyber tools will enable data protection systems to deliver the speedy recovery that’s both needed and expected.

Compared to current solutions, this new approach will dramatically improve security analysis and remediation, since backup data is offline, every restore point can be tested automatically and analysis does not impact production environments. Utilizing backup and replication data sets for cybersecurity purposes is a completely new methodology for attaining a multi-layered security program at a cost that’s practical for all IT shops, not just enterprises with enormous budgets.

New approaches can provide dramatic improvements in the security posture of an organization by examining a previously inaccessible, but endlessly rich data source for advance threat detection, analysis and remediation. It’s widely agreed that every organization would benefit from more effective cybersecurity tools. Forward-looking IT shops will begin turning to the very backup and replication data sets already being captured to create a more robust, cost-effective cybersecurity strategy.

Unauthorized users accessed HSBC accounts between Oct. 4 and 14, the bank reports in a letter to customers.

HSBC Bank has informed account holders of a data breach affecting an undisclosed number of users, the organization reported this week. In a letter sent to customers and the California Attorney General's Office, it states online accounts were compromised from Oct. 4to 14.

The bank reports compromised information may include full names, mailing and email addresses, phone numbers, birthdates, transaction histories, payee account data, statement histories, and account numbers, types, and balances.

HSBC suspended access to affected accounts and is contacting victims about changing their online credentials. It says it has improved its authentication process for HSBC Personal Internet Banking and is offering customers a complimentary, year-long subscription to Identity Guard, which they can use to monitor accounts for credit fraud and malicious activity.

Data leaks caused by negligent third-party providers are increasingly common, says High-Tech Bridge founder and CEO Ilia Kolochenko. Oftentimes, large businesses deploy demo systems to production and forget about them, leaving data and systems vulnerable. Abandoned US-based Web systems containing customer data could be a possible attack vector.

HSBC's response has been prompt and technically adequate, he explains, but there is still potential for consequences. "This will, however, unlikely exonerate them from private lawsuits and, perhaps, even a class action by disgruntled customers and privacy watchdogs,"Kolochenko says.

          Negative Impact of Incorrect CSP Implementations      Cache   Translate Page      

Content Security Policy (CSP) is an effective client-side security measure that is designed to prevent vulnerabilities such as Cross-Site Scripting (XSS) and Clickjacking. Following the regular discovery of bypass techniques, a group of researchers led by Google managed to fix these weaknesses in CSP version 3.0. With each new bypass that surfaces, browser developers continue to strengthen CSP.


Negative Impact of Incorrect CSP Implementations

However, bypasses aren’t the only issue with CSP. Incorrect CSP implementations can also pose critical problems. Keeping in mind that security is not a one time fix, but a process, we’re convinced that a significant portion of a secure CSP policy lies in understanding and implementing it correctly.

Incorrect CSP Implementations

Useless CSP reports all websites that have incorrectly implemented CSPs. Let’s take a look at some examples.

Incorrect CSP Implementation on The New Yorker

In our first example, let’s look at the CSP header from the HTTP response of The New Yorker of August 31, 2018:

Content-Security-Policy: default-src https: data: 'unsafe-inline' 'unsafe-eval';
child-src https: data: blob:;
connect-src https: data: blob:;
font-src https: data:;
img-src https: blob: data:;
media-src blob: data: https:;
object-src https:;
script-src https: data: blob: 'unsafe-inline' 'unsafe-eval';
style-src https: 'unsafe-inline';
block-all-mixed-content;
upgrade-insecure-requests;
report-uri
https://capture.condenastdigital.com/csp/the-new-yorker

A quick analysis reveals the following:

The CSP commands unsafe-inline and unsafe-eval allow inline scripts and scripts from event attributes to execute, something that is highly damaging to the website’s client-site security Really, the only good thing about the header above is that it enforces HTTPS Incorrect CSP Implementation on Blogger

Another incorrectly implemented CSP header reported on Useless CSP was found on Google’s blog service, Blogger:

content-security-policy: script-src 'self' *.google.com *.google-analytics.com 'unsafe-inline' 'unsafe-eval' *.gstatic.com *.googlesyndication.com *.blogger.com *.googleapis.com uds.googleusercontent.com https://s.ytimg.com https://i18n-cloud.appspot.com www-onepick-opensocial.googleusercontent.com www-bloggervideo-opensocial.googleusercontent.com www-blogger-opensocial.googleusercontent.com https://www.blogblog.com; report-uri /cspreport

Yet again, note the unsafe-inline and unsafe-eval keywords, which effectively disable any script execution restrictions that were put in place by the whitelisting of certain websites. This was an eye-watering discovering, considering Google is among the leading companies promoting the development of CSP.

Conclusions These errors demonstrate the fact that everyone makes mistakes, showing how important it is to use an automated web application security scanner which will detect them for you. It’s not always easy to add CSP to an existing website. There are many factors developers need to consider when they need to decide from where external resources should be loaded. This involves caching, available bandwidth and general performance. Security often ranks low on the list of considerations. In order to effectively implement CSP, you either need to consider it before writing the application (the easiest option) or find a way add it on top of your existing applications with the tools CSP provides, most notably nonces and hashes. The problem with these examples are the commands unsafe-inline and unsafe-eval , which remove most of the protections CSP provides against Cross Site Scripting. How to Ensure a Good CSP Setup

CSP version 3.0 introduced the option to whitelist code blocks using the strict-dynamic directive. Strict-dynamic (covered in detail later in the post) allows some unsafe options such as unsafe-inline and unsafe-eval to be overridden in CSP 3.0. Whitelisting the data: protocol in script-src and default-src directives lays the grounds for attacks such as the following:

www.victim.com/index.php?jsfile=data:,alert(1) <script src="data:,alert(1);"></script>

You can find more examples on the Useless CSP website.

Common Issues in CSP Implementations and Solutions

An incorrect CSP header implementation not only impacts the security of your website, but can also affect its operation. Websites today rely heavily on third-party sources. These resources are often loaded from the subdomains of the same website (e.g. static.example.com , scripts.example.com).

The use of inline scripts and javascript code in event handlers of HTML elements is quite popular among developers, but that habit isn’t really compatible with CSP. It’s clever to move inline scripts to a subdomain instead, and load them as an external script. Additionally, the host of all the external scripts must be whitelisted in your Content Security Policy, even if you own the subdomains from which the scripts are loaded.

How To Determine Whether Your CSP Implementation is Problematic

In practice, there are only three ways to find out whether you’ll have a problem in the implementation of CSP:

You could visit every page and check for errors in your browser’s developer console You could wait for the customer complains that your site doesn’t work correctly You could use the CSP Report-Only mode

Naturally, we recommend the third option.

Testing CSP Implementation with the Report-Only CSP Monitoring Mode

But how does the report-only mode work? Before publishing the CSP headers on your website, you can try them in Report-Only mode. In Report-Only mode, the CSP directives are not enforced. Instead the browser reports issues regarding the CSP to an end-point specified in the report-uri attribute. This way, you can find any missing directives, the changes you need to implement and the links you have to whitelist in the CSP header before you enforce these rules. In addition, it helps you to detect inline JavaScript codes and styles and move them into their respective external file.

Here is an example:

Content-Security-Policy-Report-Only: script-src 'self'; report-uri /my_amazing_csp_report_parser;

This sample script-src directive exclusively whitelists its own origin. All script loadings, inline scripts and script codes in event attributes coming from any other origin will trigger the CSP to send a notification to the end-point specified in the report-uri attribute.

After the testing is complete and you’re ready to push your CSP commands live, you’ll have to disable the Report-Only mode for them to be effective.

This is what the code would look like:

Content-Security-Policy: script-src 'self'; report-uri /my_amazing_csp_report_parser;

Note that even though some CSP directives can be set using HTML’s meta tags, when in Report-Only mode you cannot do that and have to use an HTTP response header instead. This screenshot shows how Netsparker reports ineffective Report-Only CSP directives in an HTML meta tag.


Negative Impact of Incorrect CSP Implementations
Content Security Policy Directives

In addition to the CSP header, Content Security Policy has many directives that allow you to configure the security of your websites.

This table lists and explains the directives that can be used to further limit and define the use of resources.

Directive Description base-uri: The base HTML element contains the absolute URL that is prepended to all the relative URLs on the page. This directive helps us restrict the URLs that are allowed to be used in the base HTML element, and therefore prevent Base Tag Hijacking attacks. child-src: This directive allows us to define which websites are permitted to be loaded in frames located on the page. We can use it as an extra precaution to protect our page from Frame Injection attacks. connect-src: This directive restricts the resources that can be loaded via script interfaces such as XHR or WebSockets. This prevents attackers from stealing data from the site. font-src: This directive specifies the font sources that can be loaded using @font-face . It is mostly used to prevent attackers from sending extracted data back to their server using the @font-face src directive. form-action: This directive specifies the URLs that can be used as targets for form submissions. It can be used as an extra precaution to protect pages from Form Tag Hijacking and Cross-Site Scripting attacks. frame-ancestors: This directive specifies the sites that have the authority to load the current page in a frame, iframe, object, embed, and applet tag. It is a substitute for X-Frame-Options, since it can also help prevent Clickjacking and UI Redressing attacks. img-src: This directive defines the sources from which images can be loaded. media-src: This directive defines or restricts the sources from which video and audio can be loaded. object-src: This directive defines or restricts the sources from <object> , <embed> , and <applet> , which helps preventing Cross-Site Scripting attacks. plugin-types: This directive defines or restricts the plugin types that can be loaded. report-uri: This directive specifies the URLs that will receive the report when a CSP directive is violated. style-src: This directive defines or restricts the sources for CSS files. This allows you to avoid data exfiltration via CSS . upgrade-insecure-requests: This directive converts the HTTP requests to HTTPS. Examples of How to Use CSP Directives Correctly

Here are a few examples of how to use CSP directives effectively.

default-src Directive Example

By default, these directives are unrestrictive, meaning that if they are not declared in the CSP header, any request will be allowed through. So, if style-src is not set, this will be interpreted as style-src: * , allowing styles from all sources.

You can use the default-src directive to change this. The specified value will override most directives ending with -src by setting a default value for them. If you set default-src to http://www.example.com , and don’t set a value for font-src , the fonts can only be loaded from http://www.example.com .

However, default-src cannot override these directives:

base-uri form-action frame-ancestors plugin-types report-uri Sandbox

This is how Netsparker reminds you that default-src does not affect certain directives.


Negative Impact of Incorrect CSP Implementations
object-src to Block Plugins

We stated above that CSP is a major mechanism in client-based security against various vulnerabilities like XSS . XSS attacks are generally carried out by script executions, so it would seem that limiting the script and style resources as a precaution might be the best way to mitigate against it. However, there are other HTML elements that can run JavaScript code, such as <embed> , <object> and <applet> .

This is how Netsparker shows that missing the object-src directive in CSP can lead to XSS.


Negative Impact of Incorrect CSP Implementations

You might not want to set the default-src since it’s a fallback mechanism and for the reasons stated above. You’ll probably never want to set it to none . However, you might want to block plugin loadings. In this case you can set object-src to none regardless of whatever you set for default-src .

Example:

Content-Security-Policy: default-src 'self'; object-src 'none';

This option will block plugins from loading on your webpage.

The Keywords That Shape the CSP Directives

Aside from specifying origins from which resources can be loaded, CSP also offers you a few keywords that allow you to further refine your CSP.

Keywords Description ‘none’: As the name suggests, nothing is allowed towill be embedded. For example, the object-src: ‘none’ command will not embed any objects on the page. ‘self’: This matches the origin of the current webpage. Resources from other origins including subdomains will not be loaded. ‘unsafe-inline’: This allows the use of inline JavaScript and CSS. ‘unsafe-eval’: This allows the use of text-to-JavaScript functions like eval(). Setting CSP in Meta Tags

Even though CSP is mostly used to define the directives in HTTP responses, you can set CSP in meta tags, too. This is ideal for situations in which you can’t set HTTP response headers:

<meta http-equiv="Content-Security-Policy" content="default-src https://cdn.example.net; child-src 'none'; object-src 'none'">

Unfortunately the following directives cannot be used when setting CSP between meta tags:

frame-ancestors, sandbox, report-uri
Negative Impact of Incorrect CSP Implementations
Getting Around the eval Function

Use of the functions eval , new Function() , setTimeOut and setInterval , which run the text inputs within the document context, is automatically blocked by CSP. To mitigate this, you must make a few changes to the code:

If the JSON parsing is carried out using the eval function, you should use the JSON.parse function The strings used in setTimeout or setInterval functions have to be changed to inline functions:

Instead of:

setTimeout("document.querySelector('a').style.display = 'none';", 10);

use:

setTimeout(() => document.querySelector('a').style.display = 'none', 10); If your template system uses generic functions such as new Function() , you can use a system that supports CSP out-of-the-box, such as Angular. You can also use pre-compilation if your template system supports it.

You can use the unsafe-eval keyword if you really have to use text-to-Javascript functions like eval. However, be warned that you’ll be creating a huge security gap in the CSP mechanism.

script-src: 'unsafe-eval' Benefits of Reorganizing the Code

An origin-based limitation mechanism could have solved a lot of problems. However, even if an origin-based mechanism was implemented, there’s would still be a large void in the XSS side, Inline Injection:

<script>alert(123);</script> <a href= onclick="javascript:alert(123)">Click me!</a> <img src=1 onerror="alert(1);"/>

CSP fixes this problem by blocking inline scripts. Not only does CSP block the codes found between the script codes, but it also blocks the script in event attributes and javascript: URLs.

Therefore you should reorganize the code within the script tags as external files on your website. Doing so has a few benefits:

Having the external files cached by the browser will improve the website performance The code will be cleaner Since you will need to minimize the JavaScript code in order to allow fast loading times, this will also make it slightly harder for attackers to find out what it does and how to exploit it

If you still insist on using inline Javascript and CSS, you must specify it within the appropriate directives:

script-src: <strong>'unsafe-inline';</strong> style-src: <strong>'unsafe-inline'</strong> Should You Use nonce or hack in the Whitelist?

When using CSP to whitelist script or style sources, you’re not limited to origin-based whitelisting the safe resources. You can also use nonce or hash functions to whitelist code blocks.

Let’s assume you have a code block as below:

<script nonce=EDNnf03nceIOfn39fn3e9h3sdfa>
//Some inline code I cant remove yet, but need to asap.
</script>
Content-Security-Policy: script-src 'nonce-EDNnf03nceIOfn39fn3e9h3sdfa'

You can whitelist the entire code block with a nonce value. As a security measure, for each request, a new nonce value has to be generated, it cannot be reused and has to be random and long.

On the other hand, while using hash instead of a nonce attribute, you can obtain a hash for the script and whitelist it in the respective header.

<script> alert('Hello, world.'); </script> Content-Security-Policy: script-src 'sha256-qznLcsROx4GACP2dm0UCKCzCG-HiZ1guq6ZZDob_Tng='

CSP supports SHA256, SHA384, and SHA512 hash algorithms.

Deprecated CSP Directives

Like any other technology, CSP has developed over time and some directives have been deprecated. You should know that the X-Content-Security-Policy and X-Webkit-CSP directives have been deprecated. Instead you can use the Content-Security-Policy directive.

Summary of a Research on CSP 3.0

A few years ago, researchers from Google released CSP is Dead, Long Live CSP , a risk analysis report on frequently used CSP headers. The research was one of the most comprehensive of its kind, covering 1,687,000 hostnames and 26,000 CSP HTTP headers. It also analyzed the three popular methods used to bypass CSP. These are Open Redirection, Insecure JSONP Endpoint, and AngularJS CSP Compatibility Mode .

Insecure Endpoint Vulnerabilities Due to Loose CSP Configuration

The report stated that in the script loadings, 14 out of 15 whitelisted domains have insecure endpoint vulnerabilities and attacks targeting them will deactivate the CSP policies.

Here are a few examples of the famous CSP bypassing methods listed in the research.

Bypassing CSP path restrictions:

Open Redirection: Content-Security-Policy: script-src example.org partially-trusted.org/foo/bar.js // Allows loading of untrusted resources via: <script src="https://www.netsparker.com//example.org?redirect=partially-trusted.org/evil/script.js">

XSS CSP whitelist bypasses

Insecure JSONP Endpoint <script src="https://www.netsparker.com/api/jsonp?callback=evil"></script> AngularJS CSP Compatibility Mode <script src="angular.js"></script> <div ng-app>{{ executeEvilCodeInUnsafeSandbox() }} </div> Using nonce-based CSP for Dynamic Uploads

Google suggests taking control of CSP policies by using nonce-based policies with dynamic uploads instead of whitelist-based policies. Google started supporting the strict-dynamic method to implement the policy it suggests to users on its own browsers. Let’s take a closer view at how this method works.

You’ll load a script over example.com/map.js . So you specify a CSP for it:

Content-Security-Policy: script-src example.com;

You trust example.com, but you also use the unsafe-inline directive to avoid the objects loaded to DOM from being stuck at the CSP barrier a small concession for you but a large weakness for the attackers.

Content-Security-Policy: script-src example.com 'unsafe-inline';

Besides, by whitelisting the example.com domain in the beginning, we cracked the door open for CSP bypasses from various attack parameters on example.com. Now let’s assume that there’s an open redirection in example.com (note this example below only works in older browsers):

example.com/redirectme.php?go=http://attacker.com/bad.js

If you used nonce-based CSP instead, you would’ve gotten rid of any potential attack vector:

Content-Security-Policy: script-src 'nonce-random-123' 'strict-dynamic'; <script src="https://example.com/map.js" nonce=random-123></script>

The above only trusts the script from example.com/map.js by assigning a nonce value to the code block where the script is loaded. By using strict-dynamic , you allow DOM manipulations to be made from this block and even allow scripts to be loaded by the whitelisted JavaScript code. By doing so, you didn’t have to whitelist the entire example.com domain nor use unsafe-inline or unsafe-eval for the loading of dynamic resources, which protects your website from various attacks.
