Flight Sim Company Threatens Reddit Mods Over “Libelous” DRM Posts

Post Syndicated from Andy original https://torrentfreak.com/flight-sim-company-threatens-reddit-mods-over-libellous-drm-posts-180604/

Earlier this year, in an effort to deal with piracy of their products, flight simulator company FlightSimLabs took drastic action by installing malware on customers’ machines.

The story began when a Reddit user reported something unusual in his download of FlightSimLabs’ A320X module. A file – test.exe – was being flagged up as a ‘Chrome Password Dump’ tool, something which rang alarm bells among flight sim fans.

As additional information was made available, the story became even more sensational. After first dodging the issue with carefully worded statements, FlightSimLabs admitted that it had installed a password dumper onto ALL users’ machines – whether they were pirates or not – in an effort to catch a particular software cracker and launch legal action.

It was an incredible story that no doubt did damage to FlightSimLabs’ reputation. But the now the company is at the center of a new storm, again centered around anti-piracy measures and again focused on Reddit.

Just before the weekend, Reddit user /u/walkday reported finding something unusual in his A320X module, the same module that caused the earlier controversy.

“The latest installer of FSLabs’ A320X puts two cmdhost.exe files under ‘system32\’ and ‘SysWOW64\’ of my Windows directory. Despite the name, they don’t open a command-line window,” he reported.

“They’re a part of the authentication because, if you remove them, the A320X won’t get loaded. Does someone here know more about cmdhost.exe? Why does FSLabs give them such a deceptive name and put them in the system folders? I hate them for polluting my system folder unless, of course, it is a dll used by different applications.”

Needless to say, the news that FSLabs were putting files into system folders named to make them look like system files was not well received.

“Hiding something named to resemble Window’s “Console Window Host” process in system folders is a huge red flag,” one user wrote.

“It’s a malware tactic used to deceive users into thinking the executable is a part of the OS, thus being trusted and not deleted. Really dodgy tactic, don’t trust it and don’t trust them,” opined another.

With a disenchanted Reddit userbase simmering away in the background, FSLabs took to Facebook with a statement to quieten down the masses.

“Over the past few hours we have become aware of rumors circulating on social media about the cmdhost file installed by the A320-X and wanted to clear up any confusion or misunderstanding,” the company wrote.

“cmdhost is part of our eSellerate infrastructure – which communicates between the eSellerate server and our product activation interface. It was designed to reduce the number of product activation issues people were having after the FSX release – which have since been resolved.”

The company noted that the file had been checked by all major anti-virus companies and everything had come back clean, which does indeed appear to be the case. Nevertheless, the critical Reddit thread remained, bemoaning the actions of a company which probably should have known better than to irritate fans after February’s debacle. In response, however, FSLabs did just that once again.

In private messages to the moderators of the /r/flightsim sub-Reddit, FSLabs’ Marketing and PR Manager Simon Kelsey suggested that the mods should do something about the thread in question or face possible legal action.

“Just a gentle reminder of Reddit’s obligations as a publisher in order to ensure that any libelous content is taken down as soon as you become aware of it,” Kelsey wrote.

Noting that FSLabs welcomes “robust fair comment and opinion”, Kelsey gave the following advice.

“The ‘cmdhost.exe’ file in question is an entirely above board part of our anti-piracy protection and has been submitted to numerous anti-virus providers in order to verify that it poses no threat. Therefore, ANY suggestion that current or future products pose any threat to users is absolutely false and libelous,” he wrote, adding:

“As we have already outlined in the past, ANY suggestion that any user’s data was compromised during the events of February is entirely false and therefore libelous.”

Noting that FSLabs would “hate for lawyers to have to get involved in this”, Kelsey advised the /r/flightsim mods to ensure that no such claims were allowed to remain on the sub-Reddit.

But after not receiving the response he would’ve liked, Kelsey wrote once again to the mods. He noted that “a number of unsubstantiated and highly defamatory comments” remained online and warned that if something wasn’t done to clean them up, he would have “no option” than to pass the matter to FSLabs’ legal team.

Like the first message, this second effort also failed to have the desired effect. In fact, the moderators’ response was to post an open letter to Kelsey and FSLabs instead.

“We sincerely disagree that you ‘welcome robust fair comment and opinion’, demonstrated by the censorship on your forums and the attempted censorship on our subreddit,” the mods wrote.

“While what you do on your forum is certainly your prerogative, your rules do not extend to Reddit nor the r/flightsim subreddit. Removing content you disagree with is simply not within our purview.”

The letter, which is worth reading in full, refutes Kelsey’s claims and also suggests that critics of FSLabs may have been subjected to Reddit vote manipulation and coordinated efforts to discredit them.

What will happen next is unclear but the matter has now been placed in the hands of Reddit’s administrators who have agreed to deal with Kelsey and FSLabs’ personally.

It’s a little early to say for sure but it seems unlikely that this will end in a net positive for FSLabs, no matter what decision Reddit’s admins take.

When Joe Public Becomes a Commercial Pirate, a Little Knowledge is Dangerous

Post Syndicated from Andy original https://torrentfreak.com/joe-public-becomes-commercial-pirate-little-knowledge-dangerous-180603/

Back in March and just a few hours before the Anthony Joshua v Joseph Parker fight, I got chatting with some fellow fans in the local pub. While some were intending to pay for the fight, others were going down the Kodi route.

Soon after the conversation switched to IPTV. One of the guys had a subscription and he said that his supplier would be along shortly if anyone wanted a package to watch the fight at home. Of course, I was curious to hear what he had to say since it’s not often this kind of thing is offered ‘offline’.

The guy revealed that he sold more or less exclusively on eBay and called up the page on his phone to show me. The listing made interesting reading.

In common with hundreds of similar IPTV subscription offers easily findable on eBay, the listing offered “All the sports and films you need plus VOD and main UK channels” for the sum of just under £60 per year, which is fairly cheap in the current market. With a non-committal “hmmm” I asked a bit more about the guy’s business and surprisingly he was happy to provide some details.

Like many people offering such packages, the guy was a reseller of someone else’s product. He also insisted that selling access to copyrighted content is OK because it sits in a “gray area”. It’s also easy to keep listings up on eBay, he assured me, as long as a few simple rules are adhered to. Right, this should be interesting.

First of all, sellers shouldn’t be “too obvious” he advised, noting that individual channels or channel lists shouldn’t be listed on the site. Fair enough, but then he said the most important thing of all is to have a disclaimer like his in any listing, written as follows:

“PLEASE NOTE EBAY: THIS IS NOT A DE SCRAMBLER SERVICE, I AM NOT SELLING ANY ILLEGAL CHANNELS OR CHANNEL LISTS NOR DO I REPRESENT ANY MEDIA COMPANY NOR HAVE ACCESS TO ANY OF THEIR CONTENTS. NO TRADEMARK HAS BEEN INFRINGED. DO NOT REMOVE LISTING AS IT IS IN ACCORDANCE WITH EBAY POLICIES.”

Apparently, this paragraph is crucial to keeping listings up on eBay and is the equivalent of kryptonite when it comes to deflecting copyright holders, police, and Trading Standards. Sure enough, a few seconds with Google reveals the same wording on dozens of eBay listings and those offering IPTV subscriptions on external platforms.

It is, of course, absolutely worthless but the IPTV seller insisted otherwise, noting he’d sold “thousands” of subscriptions through eBay without any problems. While a similar logic can be applied to garlic and vampires, a second disclaimer found on many other illicit IPTV subscription listings treads an even more bizarre path.

“THE PRODUCTS OFFERED CAN NOT BE USED TO DESCRAMBLE OR OTHERWISE ENABLE ACCESS TO CABLE OR SATELLITE TELEVISION PROGRAMS THAT BYPASSES PAYMENT TO THE SERVICE PROVIDER. RECEIVING SUBSCRIPTION/BASED TV AIRTIME IS ILLEGAL WITHOUT PAYING FOR IT.”

This disclaimer (which apparently no sellers displaying it have ever read) seems to be have been culled from the Zgemma site, which advertises a receiving device which can technically receive pirate IPTV services but wasn’t designed for the purpose. In that context, the disclaimer makes sense but when applied to dedicated pirate IPTV subscriptions, it’s absolutely ridiculous.

It’s unclear why so many sellers on eBay, Gumtree, Craigslist and other platforms think that these disclaimers are useful. It leads one to the likely conclusion that these aren’t hardcore pirates at all but regular people simply out to make a bit of extra cash who have received bad advice.

What is clear, however, is that selling access to thousands of otherwise subscription channels without permission from copyright owners is definitely illegal in the EU. The European Court of Justice says so (1,2) and it’s been backed up by subsequent cases in the Netherlands.

While the odds of getting criminally prosecuted or sued for reselling such a service are relatively slim, it’s worrying that in 2018 people still believe that doing so is made legal by the inclusion of a paragraph of text. It’s even more worrying that these individuals apparently have no idea of the serious consequences should they become singled out for legal action.

Even more surprisingly, TorrentFreak spoke with a handful of IPTV suppliers higher up the chain who also told us that what they are doing is legal. A couple claimed to be protected by communication intermediary laws, others didn’t want to go into details. Most stopped responding to emails on the topic. Perhaps most tellingly, none wanted to go on the record.

The big take-home here is that following some important EU rulings, knowingly linking to copyrighted content for profit is nearly always illegal in Europe and leaves people open for targeting by copyright holders and the authorities. People really should be aware of that, especially the little guy making a little extra pocket money on eBay.

Of course, people are perfectly entitled to carry on regardless and test the limits of the law when things go wrong. At this point, however, it’s probably worth noting that IPTV provider Ace Hosting recently handed over £600,000 rather than fight the Premier League (1,2) when they clearly had the money to put up a defense.

Given their effectiveness, perhaps they should’ve put up a disclaimer instead?

Storing Encrypted Credentials In Git

Post Syndicated from Bozho original https://techblog.bozho.net/storing-encrypted-credentials-in-git/

We all know that we should not commit any passwords or keys to the repo with our code (no matter if public or private). Yet, thousands of production passwords can be found on GitHub (and probably thousands more in internal company repositories). Some have tried to fix that by removing the passwords (once they learned it’s not a good idea to store them publicly), but passwords have remained in the git history.

Knowing what not to do is the first and very important step. But how do we store production credentials. Database credentials, system secrets (e.g. for HMACs), access keys for 3rd party services like payment providers or social networks. There doesn’t seem to be an agreed upon solution.

I’ve previously argued with the 12-factor app recommendation to use environment variables – if you have a few that might be okay, but when the number of variables grow (as in any real application), it becomes impractical. And you can set environment variables via a bash script, but you’d have to store it somewhere. And in fact, even separate environment variables should be stored somewhere.

This somewhere could be a local directory (risky), a shared storage, e.g. FTP or S3 bucket with limited access, or a separate git repository. I think I prefer the git repository as it allows versioning (Note: S3 also does, but is provider-specific). So you can store all your environment-specific properties files with all their credentials and environment-specific configurations in a git repo with limited access (only Ops people). And that’s not bad, as long as it’s not the same repo as the source code.

Such a repo would look like this:

project
└─── production
|   |   application.properites
|   |   keystore.jks
└─── staging
|   |   application.properites
|   |   keystore.jks
└─── on-premise-client1
|   |   application.properites
|   |   keystore.jks
└─── on-premise-client2
|   |   application.properites
|   |   keystore.jks

Since many companies are using GitHub or BitBucket for their repositories, storing production credentials on a public provider may still be risky. That’s why it’s a good idea to encrypt the files in the repository. A good way to do it is via git-crypt. It is “transparent” encryption because it supports diff and encryption and decryption on the fly. Once you set it up, you continue working with the repo as if it’s not encrypted. There’s even a fork that works on Windows.

You simply run git-crypt init (after you’ve put the git-crypt binary on your OS Path), which generates a key. Then you specify your .gitattributes, e.g. like that:

secretfile filter=git-crypt diff=git-crypt
*.key filter=git-crypt diff=git-crypt
*.properties filter=git-crypt diff=git-crypt
*.jks filter=git-crypt diff=git-crypt

And you’re done. Well, almost. If this is a fresh repo, everything is good. If it is an existing repo, you’d have to clean up your history which contains the unencrypted files. Following these steps will get you there, with one addition – before calling git commit, you should call git-crypt status -f so that the existing files are actually encrypted.

You’re almost done. We should somehow share and backup the keys. For the sharing part, it’s not a big issue to have a team of 2-3 Ops people share the same key, but you could also use the GPG option of git-crypt (as documented in the README). What’s left is to backup your secret key (that’s generated in the .git/git-crypt directory). You can store it (password-protected) in some other storage, be it a company shared folder, Dropbox/Google Drive, or even your email. Just make sure your computer is not the only place where it’s present and that it’s protected. I don’t think key rotation is necessary, but you can devise some rotation procedure.

git-crypt authors claim to shine when it comes to encrypting just a few files in an otherwise public repo. And recommend looking at git-remote-gcrypt. But as often there are non-sensitive parts of environment-specific configurations, you may not want to encrypt everything. And I think it’s perfectly fine to use git-crypt even in a separate repo scenario. And even though encryption is an okay approach to protect credentials in your source code repo, it’s still not necessarily a good idea to have the environment configurations in the same repo. Especially given that different people/teams manage these credentials. Even in small companies, maybe not all members have production access.

The outstanding questions in this case is – how do you sync the properties with code changes. Sometimes the code adds new properties that should be reflected in the environment configurations. There are two scenarios here – first, properties that could vary across environments, but can have default values (e.g. scheduled job periods), and second, properties that require explicit configuration (e.g. database credentials). The former can have the default values bundled in the code repo and therefore in the release artifact, allowing external files to override them. The latter should be announced to the people who do the deployment so that they can set the proper values.

The whole process of having versioned environment-speific configurations is actually quite simple and logical, even with the encryption added to the picture. And I think it’s a good security practice we should try to follow.

Some quick thoughts on the public discussion regarding facial recognition and Amazon Rekognition this past week

Post Syndicated from Dr. Matt Wood original https://aws.amazon.com/blogs/aws/some-quick-thoughts-on-the-public-discussion-regarding-facial-recognition-and-amazon-rekognition-this-past-week/

We have seen a lot of discussion this past week about the role of Amazon Rekognition in facial recognition, surveillance, and civil liberties, and we wanted to share some thoughts.

Amazon Rekognition is a service we announced in 2016. It makes use of new technologies – such as deep learning – and puts them in the hands of developers in an easy-to-use, low-cost way. Since then, we have seen customers use the image and video analysis capabilities of Amazon Rekognition in ways that materially benefit both society (e.g. preventing human trafficking, inhibiting child exploitation, reuniting missing children with their families, and building educational apps for children), and organizations (enhancing security through multi-factor authentication, finding images more easily, or preventing package theft). Amazon Web Services (AWS) is not the only provider of services like these, and we remain excited about how image and video analysis can be a driver for good in the world, including in the public sector and law enforcement.

There have always been and will always be risks with new technology capabilities. Each organization choosing to employ technology must act responsibly or risk legal penalties and public condemnation. AWS takes its responsibilities seriously. But we believe it is the wrong approach to impose a ban on promising new technologies because they might be used by bad actors for nefarious purposes in the future. The world would be a very different place if we had restricted people from buying computers because it was possible to use that computer to do harm. The same can be said of thousands of technologies upon which we all rely each day. Through responsible use, the benefits have far outweighed the risks.

Customers are off to a great start with Amazon Rekognition; the evidence of the positive impact this new technology can provide is strong (and growing by the week), and we’re excited to continue to support our customers in its responsible use.

GoDaddy to Suspend ‘Pirate’ Domain Following Music Industry Complaints

Post Syndicated from Andy original https://torrentfreak.com/godaddy-to-suspend-pirate-domain-following-music-industry-complaints-180601/

Most piracy-focused sites online conduct their business with minimal interference from outside parties. In many cases, a heap of DMCA notices filed with Google represents the most visible irritant.

Others, particularly those with large audiences, can find themselves on the end of a web blockade. Mostly court-ordered, blocking measures restrict the ability of Internet users to visit a site due to ISPs restricting traffic.

In some regions, where copyright holders have the means to do so, they choose to tackle a site’s infrastructure instead, which could mean complaints to webhosts or other service providers. At times, this has included domain registries, who are asked to disable domains on copyright grounds.

This is exactly what has happened to Fox-MusicaGratis.com, a Spanish-language music piracy site that incurred the wrath of IFPI member UNIMPRO – the Peruvian Union of Phonographic Producers.

Pirate music, suspended domain

In a process that’s becoming more common in the region, UNIMPRO initially filed a complaint with the Copyright Commission (Comisión de Derecho de Autor (CDA)) which conducted an investigation into the platform’s activities.

“The CDA considered, among other things, the irreparable damage that would have been caused to the legitimate rights owners, taking into account the large number of users who could potentially have visited said website, which was making available endless musical recordings for commercial purposes, without authorization of the holders of rights,” a statement from CDA reads.

The administrative process was carried out locally with the involvement of the National Institute for the Defense of Competition and the Protection of Intellectual Property (Indecopi), an autonomous public body tasked with handling anti-competitive behavior, unfair competition, and intellectual property matters.

Indecopi HQ

The matter was decided in favor of the rightsholders and a subsequent ruling included an instruction for US-based domain name registry GoDaddy to suspend Fox-MusicaGratis.com. According to the copyright protection entity, GoDaddy agreed to comply, to prevent further infringement.

This latest action involving a music piracy site registered with GoDaddy follows on the heels of a similar enforcement process back in March.

Mp3Juices-Download-Free.com, Melodiavip.net, Foxmusica.site and Fulltono.me were all music sites offering MP3 content without copyright holders’ permission. They too were the subject of an UNIMPRO complaint which resulted in orders for GoDaddy to suspend their domains.

In the cases of all five websites, GoDaddy was given the chance to appeal but there is no indication that the company has done so. GoDaddy did not respond to a request for comment.

New – Pay-per-Session Pricing for Amazon QuickSight, Another Region, and Lots More

Post Syndicated from Jeff Barr original https://aws.amazon.com/blogs/aws/new-pay-per-session-pricing-for-amazon-quicksight-another-region-and-lots-more/

Amazon QuickSight is a fully managed cloud business intelligence system that gives you Fast & Easy to Use Business Analytics for Big Data. QuickSight makes business analytics available to organizations of all shapes and sizes, with the ability to access data that is stored in your Amazon Redshift data warehouse, your Amazon Relational Database Service (RDS) relational databases, flat files in S3, and (via connectors) data stored in on-premises MySQL, PostgreSQL, and SQL Server databases. QuickSight scales to accommodate tens, hundreds, or thousands of users per organization.

Today we are launching a new, session-based pricing option for QuickSight, along with additional region support and other important new features. Let’s take a look at each one:

Pay-per-Session Pricing
Our customers are making great use of QuickSight and take full advantage of the power it gives them to connect to data sources, create reports, and and explore visualizations.

However, not everyone in an organization needs or wants such powerful authoring capabilities. Having access to curated data in dashboards and being able to interact with the data by drilling down, filtering, or slicing-and-dicing is more than adequate for their needs. Subscribing them to a monthly or annual plan can be seen as an unwarranted expense, so a lot of such casual users end up not having access to interactive data or BI.

In order to allow customers to provide all of their users with interactive dashboards and reports, the Enterprise Edition of Amazon QuickSight now allows Reader access to dashboards on a Pay-per-Session basis. QuickSight users are now classified as Admins, Authors, or Readers, with distinct capabilities and prices:

Authors have access to the full power of QuickSight; they can establish database connections, upload new data, create ad hoc visualizations, and publish dashboards, all for $9 per month (Standard Edition) or $18 per month (Enterprise Edition).

Readers can view dashboards, slice and dice data using drill downs, filters and on-screen controls, and download data in CSV format, all within the secure QuickSight environment. Readers pay $0.30 for 30 minutes of access, with a monthly maximum of $5 per reader.

Admins have all authoring capabilities, and can manage users and purchase SPICE capacity in the account. The QuickSight admin now has the ability to set the desired option (Author or Reader) when they invite members of their organization to use QuickSight. They can extend Reader invites to their entire user base without incurring any up-front or monthly costs, paying only for the actual usage.

To learn more, visit the QuickSight Pricing page.

A New Region
QuickSight is now available in the Asia Pacific (Tokyo) Region:

The UI is in English, with a localized version in the works.

Hourly Data Refresh
Enterprise Edition SPICE data sets can now be set to refresh as frequently as every hour. In the past, each data set could be refreshed up to 5 times a day. To learn more, read Refreshing Imported Data.

Access to Data in Private VPCs
This feature was launched in preview form late last year, and is now available in production form to users of the Enterprise Edition. As I noted at the time, you can use it to implement secure, private communication with data sources that do not have public connectivity, including on-premises data in Teradata or SQL Server, accessed over an AWS Direct Connect link. To learn more, read Working with AWS VPC.

Parameters with On-Screen Controls
QuickSight dashboards can now include parameters that are set using on-screen dropdown, text box, numeric slider or date picker controls. The default value for each parameter can be set based on the user name (QuickSight calls this a dynamic default). You could, for example, set an appropriate default based on each user’s office location, department, or sales territory. Here’s an example:

To learn more, read about Parameters in QuickSight.

URL Actions for Linked Dashboards
You can now connect your QuickSight dashboards to external applications by defining URL actions on visuals. The actions can include parameters, and become available in the Details menu for the visual. URL actions are defined like this:

You can use this feature to link QuickSight dashboards to third party applications (e.g. Salesforce) or to your own internal applications. Read Custom URL Actions to learn how to use this feature.

Dashboard Sharing
You can now share QuickSight dashboards across every user in an account.

Larger SPICE Tables
The per-data set limit for SPICE tables has been raised from 10 GB to 25 GB.

Upgrade to Enterprise Edition
The QuickSight administrator can now upgrade an account from Standard Edition to Enterprise Edition with a click. This enables provisioning of Readers with pay-per-session pricing, private VPC access, row-level security for dashboards and data sets, and hourly refresh of data sets. Enterprise Edition pricing applies after the upgrade.

Available Now
Everything I listed above is available now and you can start using it today!

You can try QuickSight for 60 days at no charge, and you can also attend our June 20th Webinar.

Majority of Canadians Consume Online Content Legally, Survey Finds

Post Syndicated from Andy original https://torrentfreak.com/majority-of-canadians-consume-online-content-legally-survey-finds-180531/

Back in January, a coalition of companies and organizations with ties to the entertainment industries called on local telecoms regulator CRTC to implement a national website blocking regime.

Under the banner of Fairplay Canada, members including Bell, Cineplex, Directors Guild of Canada, Maple Leaf Sports and Entertainment, Movie Theatre Association of Canada, and Rogers Media, spoke of an industry under threat from marauding pirates. But just how serious is this threat?

The results of a new survey commissioned by Innovation Science and Economic Development Canada (ISED) in collaboration with the Department of Canadian Heritage (PCH) aims to shine light on the problem by revealing the online content consumption habits of citizens in the Great White North.

While there are interesting findings for those on both sides of the site-blocking debate, the situation seems somewhat removed from the Armageddon scenario predicted by the entertainment industries.

Carried out among 3,301 Canadians aged 12 years and over, the Kantar TNS study aims to cover copyright infringement in six key content areas – music, movies, TV shows, video games, computer software, and eBooks. Attitudes and behaviors are also touched upon while measuring the effectiveness of Canada’s copyright measures.

General Digital Content Consumption

In its introduction, the report notes that 28 million Canadians used the Internet in the three-month study period to November 27, 2017. Of those, 22 million (80%) consumed digital content. Around 20 million (73%) streamed or accessed content, 16 million (59%) downloaded content, while 8 million (28%) shared content.

Music, TV shows and movies all battled for first place in the consumption ranks, with 48%, 48%, and 46% respectively.

Copyright Infringement

According to the study, the majority of Canadians do things completely by the book. An impressive 74% of media-consuming respondents said that they’d only accessed material from legal sources in the preceding three months.

The remaining 26% admitted to accessing at least one illegal file in the same period. Of those, just 5% said that all of their consumption was from illegal sources, with movies (36%), software (36%), TV shows (34%) and video games (33%) the most likely content to be consumed illegally.

Interestingly, the study found that few demographic factors – such as gender, region, rural and urban, income, employment status and language – play a role in illegal content consumption.

“We found that only age and income varied significantly between consumers who infringed by downloading or streaming/accessing content online illegally and consumers who did not consume infringing content online,” the report reads.

“More specifically, the profile of consumers who downloaded or streamed/accessed infringing content skewed slightly younger and towards individuals with household incomes of $100K+.”

Licensed services much more popular than pirate haunts

It will come as no surprise that Netflix was the most popular service with consumers, with 64% having used it in the past three months. Sites like YouTube and Facebook were a big hit too, visited by 36% and 28% of content consumers respectively.

Overall, 74% of online content consumers use licensed services for content while 42% use social networks. Under a third (31%) use a combination of peer-to-peer (BitTorrent), cyberlocker platforms, or linking sites. Stream-ripping services are used by 9% of content consumers.

“Consumers who reported downloading or streaming/accessing infringing content only are less likely to use licensed services and more likely to use peer-to-peer/cyberlocker/linking sites than other consumers of online content,” the report notes.

Attitudes towards legal consumption & infringing content

In common with similar surveys over the years, the Kantar research looked at the reasons why people consume content from various sources, both legal and otherwise.

Convenience (48%), speed (36%) and quality (34%) were the most-cited reasons for using legal sources. An interesting 33% of respondents said they use legal sites to avoid using illegal sources.

On the illicit front, 54% of those who obtained unauthorized content in the previous three months said they did so due to it being free, with 40% citing convenience and 34% mentioning speed.

Almost six out of ten (58%) said lower costs would encourage them to switch to official sources, with 47% saying they’d move if legal availability was improved.

Canada’s ‘Notice-and-Notice’ warning system

People in Canada who share content on peer-to-peer systems like BitTorrent without permission run the risk of receiving an infringement notice warning them to stop. These are sent by copyright holders via users’ ISPs and the hope is that the shock of receiving a warning will turn consumers back to the straight and narrow.

The study reveals that 10% of online content consumers over the age of 12 have received one of these notices but what kind of effect have they had?

“Respondents reported that receiving such a notice resulted in the following: increased awareness of copyright infringement (38%), taking steps to ensure password protected home networks (27%), a household discussion about copyright infringement (27%), and discontinuing illegal downloading or streaming (24%),” the report notes.

While these are all positives for the entertainment industries, Kantar reports that almost a quarter (24%) of people who receive a notice simply ignore them.

Stream-ripping

Once upon a time, people obtaining music via P2P networks was cited as the music industry’s greatest threat but, with the advent of sites like YouTube, so-called stream-ripping is the latest bogeyman.

According to the study, 11% of Internet users say they’ve used a stream-ripping service. They are most likely to be male (62%) and predominantly 18 to 34 (52%) years of age.

“Among Canadians who have used a service to stream-rip music or entertainment, nearly half (48%) have used stream-ripping sites, one-third have used downloader apps (38%), one-in-seven (14%) have used a stream-ripping plug-in, and one-in-ten (10%) have used stream-ripping software,” the report adds.

Set-Top Boxes and VPNs

Few general piracy studies would be complete in 2018 without touching on set-top devices and Virtual Private Networks and this report doesn’t disappoint.

More than one in five (21%) respondents aged 12+ reported using a VPN, with the main purpose of securing communications and Internet browsing (57%).

A relatively modest 36% said they use a VPN to access free content while 32% said the aim was to access geo-blocked content unavailable in Canada. Just over a quarter (27%) said that accessing content from overseas at a reasonable price was the main motivator.

One in ten (10%) of respondents reported using a set-top box, with 78% stating they use them to access paid-for content. Interestingly, only a small number say they use the devices to infringe.

“A minority use set-top boxes to access other content that is not legal or they are unsure if it is legal (16%), or to access live sports that are not legal or they are unsure if it is legal (11%),” the report notes.

“Individuals who consumed a mix of legal and illegal content online are more likely to use VPN services (42%) or TV set-top boxes (21%) than consumers who only downloaded or streamed/accessed legal content.”

Kantar says that the findings of the report will be used to help policymakers evaluate how Canada’s Copyright Act is coping with a changing market and technological developments.

“This research will provide the necessary information required to further develop copyright policy in Canada, as well as to provide a foundation to assess the effectiveness of the measures to address copyright infringement, should future analysis be undertaken,” it concludes.

FCC Asks Amazon & eBay to Help Eliminate Pirate Media Box Sales

Post Syndicated from Andy original https://torrentfreak.com/fcc-asks-amazon-ebay-to-help-eliminate-pirate-media-box-sales-180530/

Over the past several years, anyone looking for a piracy-configured set-top box could do worse than search for one on Amazon or eBay.

Historically, people deploying search terms including “Kodi” or “fully-loaded” were greeted by page after page of Android-type boxes, each ready for illicit plug-and-play entertainment consumption following delivery.

Although the problem persists on both platforms, people are now much less likely to find infringing devices than they were 12 to 24 months ago. Under pressure from entertainment industry groups, both Amazon and eBay have tightened the screws on sellers of such devices. Now, however, both companies have received requests to stem sales from a completetey different direction.

In a letter to eBay CEO Devin Wenig and Amazon CEO Jeff Bezos first spotted by Ars, FCC Commissioner Michael O’Rielly calls on the platforms to take action against piracy-configured boxes that fail to comply with FCC equipment authorization requirements or falsely display FCC logos, contrary to United States law.

“Disturbingly, some rogue set-top box manufacturers and distributors are exploiting the FCC’s trusted logo by fraudulently placing it on devices that have not been approved via the Commission’s equipment authorization process,” O’Rielly’s letter reads.

“Specifically, nine set-top box distributors were referred to the FCC in October for enabling the unlawful streaming of copyrighted material, seven of which displayed the FCC logo, although there was no record of such compliance.”

While O’Rielly admits that the copyright infringement aspects fall outside the jurisdiction of the FCC, he says it’s troubling that many of these devices are used to stream infringing content, “exacerbating the theft of billions of dollars in American innovation and creativity.”

As noted above, both Amazon and eBay have taken steps to reduce sales of pirate boxes on their respective platforms on copyright infringement grounds, something which is duly noted by O’Rielly. However, he points out that devices continue to be sold to members of the public who may believe that the devices are legal since they’re available for sale from legitimate companies.

“For these reasons, I am seeking your further cooperation in assisting the FCC in taking steps to eliminate the non-FCC compliant devices or devices that fraudulently bear the FCC logo,” the Commissioner writes (pdf).

“Moreover, if your company is made aware by the Commission, with supporting evidence, that a particular device is using a fraudulent FCC label or has not been appropriately certified and labeled with a valid FCC logo, I respectfully request that you commit to swiftly removing these products from your sites.”

In the event that Amazon and eBay take action under this request, O’Rielly asks both platforms to hand over information they hold on offending manufacturers, distributors, and suppliers.

Amazon was quick to respond to the FCC. In a letter published by Ars, Amazon’s Public Policy Vice President Brian Huseman assured O’Rielly that the company is not only dedicated to tackling rogue devices on copyright-infringement grounds but also when there is fraudulent use of the FCC’s logos.

Noting that Amazon is a key member of the Alliance for Creativity and Entertainment (ACE) – a group that has been taking legal action against sellers of infringing streaming devices (ISDs) and those who make infringing addons for Kodi-type systems – Huseman says that dealing with the problem is a top priority.

“Our goal is to prevent the sale of ISDs anywhere, as we seek to protect our customers from the risks posed by these devices, in addition to our interest in protecting Amazon Studios content,” Huseman writes.

“In 2017, Amazon became the first online marketplace to prohibit the sale of streaming media players that promote or facilitate piracy. To prevent the sale of these devices, we proactively scan product listings for signs of potentially infringing products, and we also invest heavily in sophisticated, automated real-time tools to review a variety of data sources and signals to identify inauthentic goods.

“These automated tools are supplemented by human reviewers that conduct manual investigations. When we suspect infringement, we take immediate action to remove suspected listings, and we also take enforcement action against sellers’ entire accounts when appropriate.”

Huseman also reveals that since implementing a proactive policy against such devices, “tens of thousands” of listings have been blocked from Amazon. In addition, the platform has been making criminal referrals to law enforcement as well as taking civil action (1,2,3) as part of ACE.

“As noted in your letter, we would also appreciate the opportunity to collaborate further with the FCC to remove non-compliant devices that improperly use the FCC logo or falsely claim FCC certification. If any FCC non-compliant devices are identified, we seek to work with you to ensure they are not offered for sale,” Huseman concludes.

Hong Kong Customs Arrest Pirate Streaming Device Vendors

Post Syndicated from Andy original https://torrentfreak.com/hong-kong-customs-arrest-pirate-streaming-device-vendors-180529/

As Internet-capable set-top boxes pour into homes across all populated continents, authorities seem almost powerless to come up with a significant response to the growing threat.

In standard form these devices, which are often Android-based, are entirely legal. However, when configured with specialist software they become piracy powerhouses providing access to all content imaginable, often at copyright holders’ expense.

A large proportion of these devices come from Asia, China in particular, but it’s relatively rare to hear of enforcement action in that part of the world. That changed this week with an announcement from Hong Kong customs detailing a series of raids in the areas of Sham Shui Po and Wan Chai.

After conducting an in-depth investigation with the assistance of copyright holders, on May 25 and 26 Customs and Excise officers launched Operation Trojan Horse, carrying out a series of raids on four premises selling suspected piracy-configured set-top boxes.

During the operation, officers arrested seven men and one woman aged between 18 and 45. Four of them were shop owners and the other four were salespeople. Around 354 suspected ‘pirate’ boxes were seized with an estimated market value of HK$320,000 (US$40,700).

“In the past few months, the department has stepped up inspections of hotspots for TV set-top boxes,” a statement from authorities reads.

“We have discovered that some shops have sold suspected illegal set-top boxes that bypass the copyright protection measures imposed by copyright holders of pay television programs allowing people to watch pay television programs for free.”

Some of the devices seized by Hong Kong Customs

During a press conference yesterday, a representative from the Customs Copyright and Trademark Investigations (Action) Division said that in the run up to the World Cup in 2018, measures against copyright infringement will be strengthened both on and online.

The announcement was welcomed by the Cable and Satellite Broadcasting Association of Asia’s (CASBAA) Coalition Against Piracy, which is back by industry heavyweights including Disney, Fox, HBO Asia, NBCUniversal, Premier League, Turner Asia-Pacific, A&E Networks, Astro, BBC Worldwide, National Basketball Association, TV5MONDE, Viacom International, and others.

“We commend the great work of Hong Kong Customs in clamping down on syndicates who profit from the sale of Illicit Streaming Devices,” said General Manager Neil Gane.

“The prevalence of ISDs in Hong Kong and across South East Asia is staggering. The criminals who sell ISDs, as well as those who operate the ISD networks and pirate websites, are profiting from the hard work of talented creators, seriously damaging the legitimate content ecosystem as well as exposing consumers to dangerous malware.”

Malware warnings are very prevalent these days but it’s not something the majority of set-top box owners have a problem with. Indeed, a study carried by Sycamore Research found that pirates aren’t easily deterred by such warnings.

Nevertheless, there are definite risks for individuals selling devices when they’re configured for piracy.

Recent cases, particularly in the UK, have shown that hefty jail sentences can hit offenders while over in the United States (1,2,3), lawsuits filed by the Alliance for Creativity and Entertainment (ACE) have the potential to end in unfavorable rulings for multiple defendants.

Although rarely reported, offenders in Hong Kong also face stiff sentences for this kind of infringement including large fines and custodial sentences of up to four years.

[$] Stratis: Easy local storage management for Linux

Post Syndicated from jake original https://lwn.net/Articles/755454/rss

Stratis is a new local
storage-management solution for Linux. It can be compared to
ZFS, Btrfs, or LVM. Its focus is on simplicity of concepts and ease of use,
while giving users access to advanced storage features. Internally,
Stratis’s implementation favors tight integration of existing
components instead of the fully-integrated, in-kernel approach that ZFS and
Btrfs use. This has benefits and drawbacks for Stratis, but also greatly
decreases the overall time needed to develop a useful and stable initial
version, which can then be a base for further improvement in later
versions. Subscribers can read on for an introduction to Stratis, by guest
author (and Stratis team lead at Red Hat) Andy Grover.

Kidnapping Fraud

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2018/05/kidnapping_frau.html

Fake kidnapping fraud:

“Most commonly we have unsolicited calls to potential victims in Australia, purporting to represent the people in authority in China and suggesting to intending victims here they have been involved in some sort of offence in China or elsewhere, for which they’re being held responsible,” Commander McLean said.

The scammers threaten the students with deportation from Australia or some kind of criminal punishment.

The victims are then coerced into providing their identification details or money to get out of the supposed trouble they’re in.

Commander McLean said there are also cases where the student is told they have to hide in a hotel room, provide compromising photos of themselves and cut off all contact.

This simulates a kidnapping.

“So having tricked the victims in Australia into providing the photographs, and money and documents and other things, they then present the information back to the unknowing families in China to suggest that their children who are abroad are in trouble,” Commander McLean said.

“So quite circular in a sense…very skilled, very cunning.”

Protecting your API using Amazon API Gateway and AWS WAF — Part I

Post Syndicated from Chris Munns original https://aws.amazon.com/blogs/compute/protecting-your-api-using-amazon-api-gateway-and-aws-waf-part-i/

This post courtesy of Thiago Morais, AWS Solutions Architect

When you build web applications or expose any data externally, you probably look for a platform where you can build highly scalable, secure, and robust REST APIs. As APIs are publicly exposed, there are a number of best practices for providing a secure mechanism to consumers using your API.

Amazon API Gateway handles all the tasks involved in accepting and processing up to hundreds of thousands of concurrent API calls, including traffic management, authorization and access control, monitoring, and API version management.

In this post, I show you how to take advantage of the regional API endpoint feature in API Gateway, so that you can create your own Amazon CloudFront distribution and secure your API using AWS WAF.

AWS WAF is a web application firewall that helps protect your web applications from common web exploits that could affect application availability, compromise security, or consume excessive resources.

As you make your APIs publicly available, you are exposed to attackers trying to exploit your services in several ways. The AWS security team published a whitepaper solution using AWS WAF, How to Mitigate OWASP’s Top 10 Web Application Vulnerabilities.

Regional API endpoints

Edge-optimized APIs are endpoints that are accessed through a CloudFront distribution created and managed by API Gateway. Before the launch of regional API endpoints, this was the default option when creating APIs using API Gateway. It primarily helped to reduce latency for API consumers that were located in different geographical locations than your API.

When API requests predominantly originate from an Amazon EC2 instance or other services within the same AWS Region as the API is deployed, a regional API endpoint typically lowers the latency of connections. It is recommended for such scenarios.

For better control around caching strategies, customers can use their own CloudFront distribution for regional APIs. They also have the ability to use AWS WAF protection, as I describe in this post.

Edge-optimized API endpoint

The following diagram is an illustrated example of the edge-optimized API endpoint where your API clients access your API through a CloudFront distribution created and managed by API Gateway.

Regional API endpoint

For the regional API endpoint, your customers access your API from the same Region in which your REST API is deployed. This helps you to reduce request latency and particularly allows you to add your own content delivery network, as needed.

Walkthrough

In this section, you implement the following steps:

  • Create a regional API using the PetStore sample API.
  • Create a CloudFront distribution for the API.
  • Test the CloudFront distribution.
  • Set up AWS WAF and create a web ACL.
  • Attach the web ACL to the CloudFront distribution.
  • Test AWS WAF protection.

Create the regional API

For this walkthrough, use an existing PetStore API. All new APIs launch by default as the regional endpoint type. To change the endpoint type for your existing API, choose the cog icon on the top right corner:

After you have created the PetStore API on your account, deploy a stage called “prod” for the PetStore API.

On the API Gateway console, select the PetStore API and choose Actions, Deploy API.

For Stage name, type prod and add a stage description.

Choose Deploy and the new API stage is created.

Use the following AWS CLI command to update your API from edge-optimized to regional:

aws apigateway update-rest-api \
--rest-api-id {rest-api-id} \
--patch-operations op=replace,path=/endpointConfiguration/types/EDGE,value=REGIONAL

A successful response looks like the following:

{
    "description": "Your first API with Amazon API Gateway. This is a sample API that integrates via HTTP with your demo Pet Store endpoints", 
    "createdDate": 1511525626, 
    "endpointConfiguration": {
        "types": [
            "REGIONAL"
        ]
    }, 
    "id": "{api-id}", 
    "name": "PetStore"
}

After you change your API endpoint to regional, you can now assign your own CloudFront distribution to this API.

Create a CloudFront distribution

To make things easier, I have provided an AWS CloudFormation template to deploy a CloudFront distribution pointing to the API that you just created. Click the button to deploy the template in the us-east-1 Region.

For Stack name, enter RegionalAPI. For APIGWEndpoint, enter your API FQDN in the following format:

{api-id}.execute-api.us-east-1.amazonaws.com

After you fill out the parameters, choose Next to continue the stack deployment. It takes a couple of minutes to finish the deployment. After it finishes, the Output tab lists the following items:

  • A CloudFront domain URL
  • An S3 bucket for CloudFront access logs
Output from CloudFormation

Output from CloudFormation

Test the CloudFront distribution

To see if the CloudFront distribution was configured correctly, use a web browser and enter the URL from your distribution, with the following parameters:

https://{your-distribution-url}.cloudfront.net/{api-stage}/pets

You should get the following output:

[
  {
    "id": 1,
    "type": "dog",
    "price": 249.99
  },
  {
    "id": 2,
    "type": "cat",
    "price": 124.99
  },
  {
    "id": 3,
    "type": "fish",
    "price": 0.99
  }
]

Set up AWS WAF and create a web ACL

With the new CloudFront distribution in place, you can now start setting up AWS WAF to protect your API.

For this demo, you deploy the AWS WAF Security Automations solution, which provides fine-grained control over the requests attempting to access your API.

For more information about deployment, see Automated Deployment. If you prefer, you can launch the solution directly into your account using the following button.

For CloudFront Access Log Bucket Name, add the name of the bucket created during the deployment of the CloudFormation stack for your CloudFront distribution.

The solution allows you to adjust thresholds and also choose which automations to enable to protect your API. After you finish configuring these settings, choose Next.

To start the deployment process in your account, follow the creation wizard and choose Create. It takes a few minutes do finish the deployment. You can follow the creation process through the CloudFormation console.

After the deployment finishes, you can see the new web ACL deployed on the AWS WAF console, AWSWAFSecurityAutomations.

Attach the AWS WAF web ACL to the CloudFront distribution

With the solution deployed, you can now attach the AWS WAF web ACL to the CloudFront distribution that you created earlier.

To assign the newly created AWS WAF web ACL, go back to your CloudFront distribution. After you open your distribution for editing, choose General, Edit.

Select the new AWS WAF web ACL that you created earlier, AWSWAFSecurityAutomations.

Save the changes to your CloudFront distribution and wait for the deployment to finish.

Test AWS WAF protection

To validate the AWS WAF Web ACL setup, use Artillery to load test your API and see AWS WAF in action.

To install Artillery on your machine, run the following command:

$ npm install -g artillery

After the installation completes, you can check if Artillery installed successfully by running the following command:

$ artillery -V
$ 1.6.0-12

As the time of publication, Artillery is on version 1.6.0-12.

One of the WAF web ACL rules that you have set up is a rate-based rule. By default, it is set up to block any requesters that exceed 2000 requests under 5 minutes. Try this out.

First, use cURL to query your distribution and see the API output:

$ curl -s https://{distribution-name}.cloudfront.net/prod/pets
[
  {
    "id": 1,
    "type": "dog",
    "price": 249.99
  },
  {
    "id": 2,
    "type": "cat",
    "price": 124.99
  },
  {
    "id": 3,
    "type": "fish",
    "price": 0.99
  }
]

Based on the test above, the result looks good. But what if you max out the 2000 requests in under 5 minutes?

Run the following Artillery command:

artillery quick -n 2000 --count 10  https://{distribution-name}.cloudfront.net/prod/pets

What you are doing is firing 2000 requests to your API from 10 concurrent users. For brevity, I am not posting the Artillery output here.

After Artillery finishes its execution, try to run the cURL request again and see what happens:

 

$ curl -s https://{distribution-name}.cloudfront.net/prod/pets

As you can see from the output above, the request was blocked by AWS WAF. Your IP address is removed from the blocked list after it falls below the request limit rate.

Conclusion

In this first part, you saw how to use the new API Gateway regional API endpoint together with Amazon CloudFront and AWS WAF to secure your API from a series of attacks.

In the second part, I will demonstrate some other techniques to protect your API using API keys and Amazon CloudFront custom headers.

C is to low level

Post Syndicated from Robert Graham original https://blog.erratasec.com/2018/05/c-is-too-low-level.html

I’m in danger of contradicting myself, after previously pointing out that x86 machine code is a high-level language, but this article claiming C is a not a low level language is bunk. C certainly has some problems, but it’s still the closest language to assembly. This is obvious by the fact it’s still the fastest compiled language. What we see is a typical academic out of touch with the real world.

The author makes the (wrong) observation that we’ve been stuck emulating the PDP-11 for the past 40 years. C was written for the PDP-11, and since then CPUs have been designed to make C run faster. The author imagines a different world, such as where CPU designers instead target something like LISP as their preferred language, or Erlang. This misunderstands the state of the market. CPUs do indeed supports lots of different abstractions, and C has evolved to accommodate this.


The author criticizes things like “out-of-order” execution which has lead to the Spectre sidechannel vulnerabilities. Out-of-order execution is necessary to make C run faster. The author claims instead that those resources should be spent on having more slower CPUs, with more threads. This sacrifices single-threaded performance in exchange for a lot more threads executing in parallel. The author cites Sparc Tx CPUs as his ideal processor.

But here’s the thing, the Sparc Tx was a failure. To be fair, it’s mostly a failure because most of the time, people wanted to run old C code instead of new Erlang code. But it was still a failure at running Erlang.

Time after time, engineers keep finding that “out-of-order”, single-threaded performance is still the winner. A good example is ARM processors for both mobile phones and servers. All the theory points to in-order CPUs as being better, but all the products are out-of-order, because this theory is wrong. The custom ARM cores from Apple and Qualcomm used in most high-end phones are so deeply out-of-order they give Intel CPUs competition. The same is true on the server front with the latest Qualcomm Centriq and Cavium ThunderX2 processors, deeply out of order supporting more than 100 instructions in flight.

The Cavium is especially telling. Its ThunderX CPU had 48 simple cores which was replaced with the ThunderX2 having 32 complex, deeply out-of-order cores. The performance increase was massive, even on multithread-friendly workloads. Every competitor to Intel’s dominance in the server space has learned the lesson from Sparc Tx: many wimpy cores is a failure, you need fewer beefy cores. Yes, they don’t need to be as beefy as Intel’s processors, but they need to be close.

Even Intel’s “Xeon Phi” custom chip learned this lesson. This is their GPU-like chip, running 60 cores with 512-bit wide “vector” (sic) instructions, designed for supercomputer applications. Its first version was purely in-order. Its current version is slightly out-of-order. It supports four threads and focuses on basic number crunching, so in-order cores seems to be the right approach, but Intel found in this case that out-of-order processing still provided a benefit. Practice is different than theory.

As an academic, the author of the above article focuses on abstractions. The criticism of C is that it has the wrong abstractions which are hard to optimize, and that if we instead expressed things in the right abstractions, it would be easier to optimize.

This is an intellectually compelling argument, but so far bunk.

The reason is that while the theoretical base language has issues, everyone programs using extensions to the language, like “intrinsics” (C ‘functions’ that map to assembly instructions). Programmers write libraries using these intrinsics, which then the rest of the normal programmers use. In other words, if your criticism is that C is not itself low level enough, it still provides the best access to low level capabilities.

Given that C can access new functionality in CPUs, CPU designers add new paradigms, from SIMD to transaction processing. In other words, while in the 1980s CPUs were designed to optimize C (stacks, scaled pointers), these days CPUs are designed to optimize tasks regardless of language.

The author of that article criticizes the memory/cache hierarchy, claiming it has problems. Yes, it has problems, but only compared to how well it normally works. The author praises the many simple cores/threads idea as hiding memory latency with little caching, but misses the point that caches also dramatically increase memory bandwidth. Intel processors are optimized to read a whopping 256 bits every clock cycle from L1 cache. Main memory bandwidth is orders of magnitude slower.

The author goes onto criticize cache coherency as a problem. C uses it, but other languages like Erlang don’t need it. But that’s largely due to the problems each languages solves. Erlang solves the problem where a large number of threads work on largely independent tasks, needing to send only small messages to each other across threads. The problems C solves is when you need many threads working on a huge, common set of data.

For example, consider the “intrusion prevention system”. Any thread can process any incoming packet that corresponds to any region of memory. There’s no practical way of solving this problem without a huge coherent cache. It doesn’t matter which language or abstractions you use, it’s the fundamental constraint of the problem being solved. RDMA is an important concept that’s moved from supercomputer applications to the data center, such as with memcached. Again, we have the problem of huge quantities (terabytes worth) shared among threads rather than small quantities (kilobytes).

The fundamental issue the author of the the paper is ignoring is decreasing marginal returns. Moore’s Law has gifted us more transistors than we can usefully use. We can’t apply those additional registers to just one thing, because the useful returns we get diminish.

For example, Intel CPUs have two hardware threads per core. That’s because there are good returns by adding a single additional thread. However, the usefulness of adding a third or fourth thread decreases. That’s why many CPUs have only two threads, or sometimes four threads, but no CPU has 16 threads per core.

You can apply the same discussion to any aspect of the CPU, from register count, to SIMD width, to cache size, to out-of-order depth, and so on. Rather than focusing on one of these things and increasing it to the extreme, CPU designers make each a bit larger every process tick that adds more transistors to the chip.

The same applies to cores. It’s why the “more simpler cores” strategy fails, because more cores have their own decreasing marginal returns. Instead of adding cores tied to limited memory bandwidth, it’s better to add more cache. Such cache already increases the size of the cores, so at some point it’s more effective to add a few out-of-order features to each core rather than more cores. And so on.

The question isn’t whether we can change this paradigm and radically redesign CPUs to match some academic’s view of the perfect abstraction. Instead, the goal is to find new uses for those additional transistors. For example, “message passing” is a useful abstraction in languages like Go and Erlang that’s often more useful than sharing memory. It’s implemented with shared memory and atomic instructions, but I can’t help but think it couldn’t better be done with direct hardware support.

Of course, as soon as they do that, it’ll become an intrinsic in C, then added to languages like Go and Erlang.

Summary

Academics live in an ideal world of abstractions, the rest of us live in practical reality. The reality is that vast majority of programmers work with the C family of languages (JavaScript, Go, etc.), whereas academics love the epiphanies they learned using other languages, especially function languages. CPUs are only superficially designed to run C and “PDP-11 compatibility”. Instead, they keep adding features to support other abstractions, abstractions available to C. They are driven by decreasing marginal returns — they would love to add new abstractions to the hardware because it’s a cheap way to make use of additional transitions. Academics are wrong believing that the entire system needs to be redesigned from scratch. Instead, they just need to come up with new abstractions CPU designers can add.

AWS GDPR Data Processing Addendum – Now Part of Service Terms

Post Syndicated from Chad Woolf original https://aws.amazon.com/blogs/security/aws-gdpr-data-processing-addendum/

Today, we’re happy to announce that the AWS GDPR Data Processing Addendum (GDPR DPA) is now part of our online Service Terms. This means all AWS customers globally can rely on the terms of the AWS GDPR DPA which will apply automatically from May 25, 2018, whenever they use AWS services to process personal data under the GDPR. The AWS GDPR DPA also includes EU Model Clauses, which were approved by the European Union (EU) data protection authorities, known as the Article 29 Working Party. This means that AWS customers wishing to transfer personal data from the European Economic Area (EEA) to other countries can do so with the knowledge that their personal data on AWS will be given the same high level of protection it receives in the EEA.

As we approach the GDPR enforcement date this week, this announcement is an important GDPR compliance component for us, our customers, and our partners. All customers which that are using cloud services to process personal data will need to have a data processing agreement in place between them and their cloud services provider if they are to comply with GDPR. As early as April 2017, AWS announced that AWS had a GDPR-ready DPA available for its customers. In this way, we started offering our GDPR DPA to customers over a year before the May 25, 2018 enforcement date. Now, with the DPA terms included in our online service terms, there is no extra engagement needed by our customers and partners to be compliant with the GDPR requirement for data processing terms.

The AWS GDPR DPA also provides our customers with a number of other important assurances, such as the following:

  • AWS will process customer data only in accordance with customer instructions.
  • AWS has implemented and will maintain robust technical and organizational measures for the AWS network.
  • AWS will notify its customers of a security incident without undue delay after becoming aware of the security incident.
  • AWS will make available certificates issued in relation to the ISO 27001 certification, the ISO 27017 certification, and the ISO 27018 certification to further help customers and partners in their own GDPR compliance activities.

Customers who have already signed an offline version of the AWS GDPR DPA can continue to rely on that GDPR DPA. By incorporating our GDPR DPA into the AWS Service Terms, we are simply extending the terms of our GDPR DPA to all customers globally who will require it under GDPR.

AWS GDPR DPA is only part of the story, however. We are continuing to work alongside our customers and partners to help them on their journey towards GDPR compliance.

If you have any questions about the GDPR or the AWS GDPR DPA, please contact your account representative, or visit the AWS GDPR Center at: https://aws.amazon.com/compliance/gdpr-center/
