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.

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.

Protecting coral reefs with Nemo-Pi, the underwater monitor

Post Syndicated from Janina Ander original https://www.raspberrypi.org/blog/coral-reefs-nemo-pi/

The German charity Save Nemo works to protect coral reefs, and they are developing Nemo-Pi, an underwater “weather station” that monitors ocean conditions. Right now, you can vote for Save Nemo in the Google.org Impact Challenge.

Nemo-Pi — Save Nemo

Save Nemo

The organisation says there are two major threats to coral reefs: divers, and climate change. To make diving saver for reefs, Save Nemo installs buoy anchor points where diving tour boats can anchor without damaging corals in the process.

In addition, they provide dos and don’ts for how to behave on a reef dive.

The Nemo-Pi

To monitor the effects of climate change, and to help divers decide whether conditions are right at a reef while they’re still on shore, Save Nemo is also in the process of perfecting Nemo-Pi.

Nemo-Pi schematic — Nemo-Pi — Save Nemo

This Raspberry Pi-powered device is made up of a buoy, a solar panel, a GPS device, a Pi, and an array of sensors. Nemo-Pi measures water conditions such as current, visibility, temperature, carbon dioxide and nitrogen oxide concentrations, and pH. It also uploads its readings live to a public webserver.

Long-term goals

Save Nemo aims to install a network of Nemo-Pis at shallow reefs (up to 60 metres deep) in South East Asia. Then diving tour companies can check the live data online and decide day-to-day whether tours are feasible. This will lower the impact of humans on reefs and help the local flora and fauna survive.

Coral reefs with fishes

Nemo-Pi data may also be useful for groups lobbying for reef conservation, and for scientists and activists who want to shine a spotlight on the awful effects of climate change on sea life, such as coral bleaching caused by rising water temperatures.

Hiring a Director of Sales

Post Syndicated from Yev original https://www.backblaze.com/blog/hiring-a-director-of-sales/

Backblaze is hiring a Director of Sales. This is a critical role for Backblaze as we continue to grow the team. We need a strong leader who has experience in scaling a sales team and who has an excellent track record for exceeding goals by selling Software as a Service (SaaS) solutions. In addition, this leader will need to be highly motivated, as well as able to create and develop a highly-motivated, success oriented sales team that has fun and enjoys what they do.

The History of Backblaze from our CEO
In 2007, after a friend’s computer crash caused her some suffering, we realized that with every photo, video, song, and document going digital, everyone would eventually lose all of their information. Five of us quit our jobs to start a company with the goal of making it easy for people to back up their data.

Like many startups, for a while we worked out of a co-founder’s one-bedroom apartment. Unlike most startups, we made an explicit agreement not to raise funding during the first year. We would then touch base every six months and decide whether to raise or not. We wanted to focus on building the company and the product, not on pitching and slide decks. And critically, we wanted to build a culture that understood money comes from customers, not the magical VC giving tree. Over the course of 5 years we built a profitable, multi-million dollar revenue business — and only then did we raise a VC round.

Fast forward 10 years later and our world looks quite different. You’ll have some fantastic assets to work with:

  • A brand millions recognize for openness, ease-of-use, and affordability.
  • A computer backup service that stores over 500 petabytes of data, has recovered over 30 billion files for hundreds of thousands of paying customers — most of whom self-identify as being the people that find and recommend technology products to their friends.
  • Our B2 service that provides the lowest cost cloud storage on the planet at 1/4th the price Amazon, Google or Microsoft charges. While being a newer product on the market, it already has over 100,000 IT and developers signed up as well as an ecosystem building up around it.
  • A growing, profitable and cash-flow positive company.
  • And last, but most definitely not least: a great sales team.

You might be saying, “sounds like you’ve got this under control — why do you need me?” Don’t be misled. We need you. Here’s why:

  • We have a great team, but we are in the process of expanding and we need to develop a structure that will easily scale and provide the most success to drive revenue.
  • We just launched our outbound sales efforts and we need someone to help develop that into a fully successful program that’s building a strong pipeline and closing business.
  • We need someone to work with the marketing department and figure out how to generate more inbound opportunities that the sales team can follow up on and close.
  • We need someone who will work closely in developing the skills of our current sales team and build a path for career growth and advancement.
  • We want someone to manage our Customer Success program.

So that’s a bit about us. What are we looking for in you?

Experience: As a sales leader, you will strategically build and drive the territory’s sales pipeline by assembling and leading a skilled team of sales professionals. This leader should be familiar with generating, developing and closing software subscription (SaaS) opportunities. We are looking for a self-starter who can manage a team and make an immediate impact of selling our Backup and Cloud Storage solutions. In this role, the sales leader will work closely with the VP of Sales, marketing staff, and service staff to develop and implement specific strategic plans to achieve and exceed revenue targets, including new business acquisition as well as build out our customer success program.

Leadership: We have an experienced team who’s brought us to where we are today. You need to have the people and management skills to get them excited about working with you. You need to be a strong leader and compassionate about developing and supporting your team.

Data driven and creative: The data has to show something makes sense before we scale it up. However, without creativity, it’s easy to say “the data shows it’s impossible” or to find a local maximum. Whether it’s deciding how to scale the team, figuring out what our outbound sales efforts should look like or putting a plan in place to develop the team for career growth, we’ve seen a bit of creativity get us places a few extra dollars couldn’t.

Jive with our culture: Strong leaders affect culture and the person we hire for this role may well shape, not only fit into, ours. But to shape the culture you have to be accepted by the organism, which means a certain set of shared values. We default to openness with our team, our customers, and everyone if possible. We love initiative — without arrogance or dictatorship. We work to create a place people enjoy showing up to work. That doesn’t mean ping pong tables and foosball (though we do try to have perks & fun), but it means people are friendly, non-political, working to build a good service but also a good place to work.

Do the work: Ideas and strategy are critical, but good execution makes them happen. We’re looking for someone who can help the team execute both from the perspective of being capable of guiding and organizing, but also someone who is hands-on themselves.

Additional Responsibilities needed for this role:

  • Recruit, coach, mentor, manage and lead a team of sales professionals to achieve yearly sales targets. This includes closing new business and expanding upon existing clientele.
  • Expand the customer success program to provide the best customer experience possible resulting in upsell opportunities and a high retention rate.
  • Develop effective sales strategies and deliver compelling product demonstrations and sales pitches.
  • Acquire and develop the appropriate sales tools to make the team efficient in their daily work flow.
  • Apply a thorough understanding of the marketplace, industry trends, funding developments, and products to all management activities and strategic sales decisions.
  • Ensure that sales department operations function smoothly, with the goal of facilitating sales and/or closings; operational responsibilities include accurate pipeline reporting and sales forecasts.
  • This position will report directly to the VP of Sales and will be staffed in our headquarters in San Mateo, CA.

Requirements:

  • 7 – 10+ years of successful sales leadership experience as measured by sales performance against goals.
    Experience in developing skill sets and providing career growth and opportunities through advancement of team members.
  • Background in selling SaaS technologies with a strong track record of success.
  • Strong presentation and communication skills.
  • Must be able to travel occasionally nationwide.
  • BA/BS degree required

Think you want to join us on this adventure?
Send an email to jobscontact@backblaze.com with the subject “Director of Sales.” (Recruiters and agencies, please don’t email us.) Include a resume and answer these two questions:

  1. How would you approach evaluating the current sales team and what is your process for developing a growth strategy to scale the team?
  2. What are the goals you would set for yourself in the 3 month and 1-year timeframes?

Thank you for taking the time to read this and I hope that this sounds like the opportunity for which you’ve been waiting.

Backblaze is an Equal Opportunity Employer.

Amazon Neptune Generally Available

Post Syndicated from Randall Hunt original https://aws.amazon.com/blogs/aws/amazon-neptune-generally-available/

Amazon Neptune is now Generally Available in US East (N. Virginia), US East (Ohio), US West (Oregon), and EU (Ireland). Amazon Neptune is a fast, reliable, fully-managed graph database service that makes it easy to build and run applications that work with highly connected datasets. At the core of Neptune is a purpose-built, high-performance graph database engine optimized for storing billions of relationships and querying the graph with millisecond latencies. Neptune supports two popular graph models, Property Graph and RDF, through Apache TinkerPop Gremlin and SPARQL, allowing you to easily build queries that efficiently navigate highly connected datasets. Neptune can be used to power everything from recommendation engines and knowledge graphs to drug discovery and network security. Neptune is fully-managed with automatic minor version upgrades, backups, encryption, and fail-over. I wrote about Neptune in detail for AWS re:Invent last year and customers have been using the preview and providing great feedback that the team has used to prepare the service for GA.

Now that Amazon Neptune is generally available there are a few changes from the preview:

Launching an Amazon Neptune Cluster

Launching a Neptune cluster is as easy as navigating to the AWS Management Console and clicking create cluster. Of course you can also launch with CloudFormation, the CLI, or the SDKs.

You can monitor your cluster health and the health of individual instances through Amazon CloudWatch and the console.

Additional Resources

We’ve created two repos with some additional tools and examples here. You can expect continuous development on these repos as we add additional tools and examples.

  • Amazon Neptune Tools Repo
    This repo has a useful tool for converting GraphML files into Neptune compatible CSVs for bulk loading from S3.
  • Amazon Neptune Samples Repo
    This repo has a really cool example of building a collaborative filtering recommendation engine for video game preferences.

Purpose Built Databases

There’s an industry trend where we’re moving more and more onto purpose-built databases. Developers and businesses want to access their data in the format that makes the most sense for their applications. As cloud resources make transforming large datasets easier with tools like AWS Glue, we have a lot more options than we used to for accessing our data. With tools like Amazon Redshift, Amazon Athena, Amazon Aurora, Amazon DynamoDB, and more we get to choose the best database for the job or even enable entirely new use-cases. Amazon Neptune is perfect for workloads where the data is highly connected across data rich edges.

I’m really excited about graph databases and I see a huge number of applications. Looking for ideas of cool things to build? I’d love to build a web crawler in AWS Lambda that uses Neptune as the backing store. You could further enrich it by running Amazon Comprehend or Amazon Rekognition on the text and images found and creating a search engine on top of Neptune.

As always, feel free to reach out in the comments or on twitter to provide any feedback!

[$] 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.

Project Floofball and more: Pi pet stuff

Post Syndicated from Janina Ander original https://www.raspberrypi.org/blog/project-floofball-pi-pet-stuff/

It’s a public holiday here today (yes, again). So, while we indulge in the traditional pastime of barbecuing stuff (ourselves, mainly), here’s a little trove of Pi projects that cater for our various furry friends.

Project Floofball

Nicole Horward created Project Floofball for her hamster, Harold. It’s an IoT hamster wheel that uses a Raspberry Pi and a magnetic door sensor to log how far Harold runs.

You can follow Harold’s runs in real time on his ThingSpeak channel, and you’ll find photos of the build on imgur. Nicole’s Python code, as well as her template for the laser-cut enclosure that houses the wiring and LCD display, are available on the hamster wheel’s GitHub repo.

A live-streaming pet feeder

JaganK3 used to work long hours that meant he couldn’t be there to feed his dog on time. He found that he couldn’t buy an automated feeder in India without paying a lot to import one, so he made one himself. It uses a Raspberry Pi to control a motor that turns a dispensing valve in a hopper full of dry food, giving his dog a portion of food at set times.

A transparent cylindrical hopper of dry dog food, with a motor that can turn a dispensing valve at the lower end. The motor is connected to a Raspberry Pi in a plastic case. Hopper, motor, Pi, and wiring are all mounted on a board on the wall.

He also added a web cam for live video streaming, because he could. Find out more in JaganK3’s Instructable for his pet feeder.

Shark laser cat toy

Sam Storino, meanwhile, is using a Raspberry Pi to control a laser-pointer cat toy with a goshdarned SHARK (which is kind of what I’d expect from the guy who made the steampunk-looking cat feeder a few weeks ago). The idea is to keep his cats interested and active within the confines of a compact city apartment.

Michel Parreno has written a series of articles to help you monitor and feed your pet with Raspberry Pi.

All of these makers are generous in acknowledging the tutorials and build logs that helped them with their projects. It’s lovely to see the Raspberry Pi and maker community working like this, and I bet their projects will inspire others too.

Now, if you’ll excuse me. I’m late for a barbecue.

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

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

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.

Use Slack ChatOps to Deploy Your Code – How to Integrate Your Pipeline in AWS CodePipeline with Your Slack Channel

Post Syndicated from Rumi Olsen original https://aws.amazon.com/blogs/devops/use-slack-chatops-to-deploy-your-code-how-to-integrate-your-pipeline-in-aws-codepipeline-with-your-slack-channel/

Slack is widely used by DevOps and development teams to communicate status. Typically, when a build has been tested and is ready to be promoted to a staging environment, a QA engineer or DevOps engineer kicks off the deployment. Using Slack in a ChatOps collaboration model, the promotion can be done in a single click from a Slack channel. And because the promotion happens through a Slack channel, the whole development team knows what’s happening without checking email.

In this blog post, I will show you how to integrate AWS services with a Slack application. I use an interactive message button and incoming webhook to promote a stage with a single click.

To follow along with the steps in this post, you’ll need a pipeline in AWS CodePipeline. If you don’t have a pipeline, the fastest way to create one for this use case is to use AWS CodeStar. Go to the AWS CodeStar console and select the Static Website template (shown in the screenshot). AWS CodeStar will create a pipeline with an AWS CodeCommit repository and an AWS CodeDeploy deployment for you. After the pipeline is created, you will need to add a manual approval stage.

You’ll also need to build a Slack app with webhooks and interactive components, write two Lambda functions, and create an API Gateway API and a SNS topic.

As you’ll see in the following diagram, when I make a change and merge a new feature into the master branch in AWS CodeCommit, the check-in kicks off my CI/CD pipeline in AWS CodePipeline. When CodePipeline reaches the approval stage, it sends a notification to Amazon SNS, which triggers an AWS Lambda function (ApprovalRequester).

The Slack channel receives a prompt that looks like the following screenshot. When I click Yes to approve the build promotion, the approval result is sent to CodePipeline through API Gateway and Lambda (ApprovalHandler). The pipeline continues on to deploy the build to the next environment.

Create a Slack app

For App Name, type a name for your app. For Development Slack Workspace, choose the name of your workspace. You’ll see in the following screenshot that my workspace is AWS ChatOps.

After the Slack application has been created, you will see the Basic Information page, where you can create incoming webhooks and enable interactive components.

To add incoming webhooks:

  1. Under Add features and functionality, choose Incoming Webhooks. Turn the feature on by selecting Off, as shown in the following screenshot.
  2. Now that the feature is turned on, choose Add New Webhook to Workspace. In the process of creating the webhook, Slack lets you choose the channel where messages will be posted.
  3. After the webhook has been created, you’ll see its URL. You will use this URL when you create the Lambda function.

If you followed the steps in the post, the pipeline should look like the following.

Write the Lambda function for approval requests

This Lambda function is invoked by the SNS notification. It sends a request that consists of an interactive message button to the incoming webhook you created earlier.  The following sample code sends the request to the incoming webhook. WEBHOOK_URL and SLACK_CHANNEL are the environment variables that hold values of the webhook URL that you created and the Slack channel where you want the interactive message button to appear.

# This function is invoked via SNS when the CodePipeline manual approval action starts.
# It will take the details from this approval notification and sent an interactive message to Slack that allows users to approve or cancel the deployment.

import os

# This is passed as a plain-text environment variable for ease of demonstration.
# Consider encrypting the value with KMS or use an encrypted parameter in Parameter Store for production deployments.
SLACK_WEBHOOK_URL = os.environ['SLACK_WEBHOOK_URL']
SLACK_CHANNEL = os.environ['SLACK_CHANNEL']

                    {
                        "name": "deployment",

                        "type": "button",
                        "value": json.dumps({"approve": True, "codePipelineToken": token, "codePipelineName": codepipeline_name}),
                        "confirm": {
                            "title": "Are you sure?",
                            "text": "This will deploy the build to production",
                            "ok_text": "Yes",
                            "dismiss_text": "No"
                        }
                    },
                    {
                        "name": "deployment",
                        "text": "No",
                        "type": "button",
                        "value": json.dumps({"approve": False, "codePipelineToken": token, "codePipelineName": codepipeline_name})
                    }  
                ]
            }
        ]
    }

    req = Request(SLACK_WEBHOOK_URL, json.dumps(slack_message).encode('utf-8'))

    response = urlopen(req)
    response.read()
    
    return None

 

Create a SNS topic

Create a topic and then create a subscription that invokes the ApprovalRequester Lambda function. You can configure the manual approval action in the pipeline to send a message to this SNS topic when an approval action is required. When the pipeline reaches the approval stage, it sends a notification to this SNS topic. SNS publishes a notification to all of the subscribed endpoints. In this case, the Lambda function is the endpoint. Therefore, it invokes and executes the Lambda function. For information about how to create a SNS topic, see Create a Topic in the Amazon SNS Developer Guide.

Write the Lambda function for handling the interactive message button

This Lambda function is invoked by API Gateway. It receives the result of the interactive message button whether or not the build promotion was approved. If approved, an API call is made to CodePipeline to promote the build to the next environment. If not approved, the pipeline stops and does not move to the next stage.

The Lambda function code might look like the following. SLACK_VERIFICATION_TOKEN is the environment variable that contains your Slack verification token. You can find your verification token under Basic Information on Slack manage app page. When you scroll down, you will see App Credential. Verification token is found under the section.

# This function is triggered via API Gateway when a user acts on the Slack interactive message sent by approval_requester.py.

from urllib.parse import parse_qs
import json
import os
import boto3

SLACK_VERIFICATION_TOKEN = os.environ['SLACK_VERIFICATION_TOKEN']

#Triggered by API Gateway
#It kicks off a particular CodePipeline project
def lambda_handler(event, context):
	#print("Received event: " + json.dumps(event, indent=2))
	body = parse_qs(event['body'])
	payload = json.loads(body['payload'][0])

	# Validate Slack token
	if SLACK_VERIFICATION_TOKEN == payload['token']:
		send_slack_message(json.loads(payload['actions'][0]['value']))
		
		# This will replace the interactive message with a simple text response.
		# You can implement a more complex message update if you would like.
		return  {
			"isBase64Encoded": "false",
			"statusCode": 200,
			"body": "{\"text\": \"The approval has been processed\"}"
		}
	else:
		return  {
			"isBase64Encoded": "false",
			"statusCode": 403,
			"body": "{\"error\": \"This request does not include a vailid verification token.\"}"
		}


def send_slack_message(action_details):
	codepipeline_status = "Approved" if action_details["approve"] else "Rejected"
	codepipeline_name = action_details["codePipelineName"]
	token = action_details["codePipelineToken"] 

	client = boto3.client('codepipeline')
	response_approval = client.put_approval_result(
							pipelineName=codepipeline_name,
							stageName='Approval',
							actionName='ApprovalOrDeny',
							result={'summary':'','status':codepipeline_status},
							token=token)
	print(response_approval)

 

Create the API Gateway API

  1. In the Amazon API Gateway console, create a resource called InteractiveMessageHandler.
  2. Create a POST method.
    • For Integration type, choose Lambda Function.
    • Select Use Lambda Proxy integration.
    • From Lambda Region, choose a region.
    • In Lambda Function, type a name for your function.
  3.  Deploy to a stage.

For more information, see Getting Started with Amazon API Gateway in the Amazon API Developer Guide.

Now go back to your Slack application and enable interactive components.

To enable interactive components for the interactive message (Yes) button:

  1. Under Features, choose Interactive Components.
  2. Choose Enable Interactive Components.
  3. Type a request URL in the text box. Use the invoke URL in Amazon API Gateway that will be called when the approval button is clicked.

Now that all the pieces have been created, run the solution by checking in a code change to your CodeCommit repo. That will release the change through CodePipeline. When the CodePipeline comes to the approval stage, it will prompt to your Slack channel to see if you want to promote the build to your staging or production environment. Choose Yes and then see if your change was deployed to the environment.

Conclusion

That is it! You have now created a Slack ChatOps solution using AWS CodeCommit, AWS CodePipeline, AWS Lambda, Amazon API Gateway, and Amazon Simple Notification Service.

Now that you know how to do this Slack and CodePipeline integration, you can use the same method to interact with other AWS services using API Gateway and Lambda. You can also use Slack’s slash command to initiate an action from a Slack channel, rather than responding in the way demonstrated in this post.

Working with the Scout Association on digital skills for life

Post Syndicated from Philip Colligan original https://www.raspberrypi.org/blog/working-with-scout-association-digital-skills-for-life/

Today we’re launching a new partnership between the Scouts and the Raspberry Pi Foundation that will help tens of thousands of young people learn crucial digital skills for life. In this blog post, I want to explain what we’ve got planned, why it matters, and how you can get involved.

This is personal

First, let me tell you why this partnership matters to me. As a child growing up in North Wales in the 1980s, Scouting changed my life. My time with 2nd Rhyl provided me with countless opportunities to grow and develop new skills. It taught me about teamwork and community in ways that continue to shape my decisions today.

As my own kids (now seven and ten) have joined Scouting, I’ve seen the same opportunities opening up for them, and like so many parents, I’ve come back to the movement as a volunteer to support their local section. So this is deeply personal for me, and the same is true for many of my colleagues at the Raspberry Pi Foundation who in different ways have been part of the Scouting movement.

That shouldn’t come as a surprise. Scouting and Raspberry Pi share many of the same values. We are both community-led movements that aim to help young people develop the skills they need for life. We are both powered by an amazing army of volunteers who give their time to support that mission. We both care about inclusiveness, and pride ourselves on combining fun with learning by doing.

Raspberry Pi

Raspberry Pi started life in 2008 as a response to the problem that too many young people were growing up without the skills to create with technology. Our goal is that everyone should be able to harness the power of computing and digital technologies, for work, to solve problems that matter to them, and to express themselves creatively.

In 2012 we launched our first product, the world’s first $35 computer. Just six years on, we have sold over 20 million Raspberry Pi computers and helped kickstart a global movement for digital skills.

The Raspberry Pi Foundation now runs the world’s largest network of volunteer-led computing clubs (Code Clubs and CoderDojos), and creates free educational resources that are used by millions of young people all over the world to learn how to create with digital technologies. And lots of what we are able to achieve is because of partnerships with fantastic organisations that share our goals. For example, through our partnership with the European Space Agency, thousands of young people have written code that has run on two Raspberry Pi computers that Tim Peake took to the International Space Station as part of his Mission Principia.

Digital makers

Today we’re launching the new Digital Maker Staged Activity Badge to help tens of thousands of young people learn how to create with technology through Scouting. Over the past few months, we’ve been working with the Scouts all over the UK to develop and test the new badge requirements, along with guidance, project ideas, and resources that really make them work for Scouting. We know that we need to get two things right: relevance and accessibility.

Relevance is all about making sure that the activities and resources we provide are a really good fit for Scouting and Scouting’s mission to equip young people with skills for life. From the digital compass to nature cameras and the reinvented wide game, we’ve had a lot of fun thinking about ways we can bring to life the crucial role that digital technologies can play in the outdoors and adventure.

Compass Coding with Raspberry Pi

We are beyond excited to be launching a new partnership with the Raspberry Pi Foundation, which will help tens of thousands of young people learn digital skills for life.

We also know that there are great opportunities for Scouts to use digital technologies to solve social problems in their communities, reflecting the movement’s commitment to social action. Today we’re launching the first set of project ideas and resources, with many more to follow over the coming weeks and months.

Accessibility is about providing every Scout leader with the confidence, support, and kit to enable them to offer the Digital Maker Staged Activity Badge to their young people. A lot of work and care has gone into designing activities that require very little equipment: for example, activities at Stages 1 and 2 can be completed with a laptop without access to the internet. For the activities that do require kit, we will be working with Scout Stores and districts to make low-cost kit available to buy or loan.

We’re producing accessible instructions, worksheets, and videos to help leaders run sessions with confidence, and we’ll also be planning training for leaders. We will work with our network of Code Clubs and CoderDojos to connect them with local sections to organise joint activities, bringing both kit and expertise along with them.




Get involved

Today’s launch is just the start. We’ll be developing our partnership over the next few years, and we can’t wait for you to join us in getting more young people making things with technology.

Take a look at the brand-new Raspberry Pi resources designed especially for Scouts, to get young people making and creating right away.

Raspberry Jam Cameroon #PiParty

Post Syndicated from Ben Nuttall original https://www.raspberrypi.org/blog/raspberry-jam-cameroon-piparty/

Earlier this year on 3 and 4 March, communities around the world held Raspberry Jam events to celebrate Raspberry Pi’s sixth birthday. We sent out special birthday kits to participating Jams — it was amazing to know the kits would end up in the hands of people in parts of the world very far from Raspberry Pi HQ in Cambridge, UK.

The Raspberry Jam Camer team: Damien Doumer, Eyong Etta, Loïc Dessap and Lionel Sichom, aka Lionel Tellem

Preparing for the #PiParty

One birthday kit went to Yaoundé, the capital of Cameroon. There, a team of four students in their twenties — Lionel Sichom (aka Lionel Tellem), Eyong Etta, Loïc Dessap, and Damien Doumer — were organising Yaoundé’s first Jam, called Raspberry Jam Camer, as part of the Raspberry Jam Big Birthday Weekend. The team knew one another through their shared interests and skills in electronics, robotics, and programming. Damien explains in his blog post about the Jam that they planned ahead for several activities for the Jam based on their own projects, so they could be confident of having a few things that would definitely be successful for attendees to do and see.

Show-and-tell at Raspberry Jam Cameroon

Loïc presented a Raspberry Pi–based, Android app–controlled robot arm that he had built, and Lionel coded a small video game using Scratch on Raspberry Pi while the audience watched. Damien demonstrated the possibilities of Windows 10 IoT Core on Raspberry Pi, showing how to install it, how to use it remotely, and what you can do with it, including building a simple application.

Loïc Dessap, wearing a Raspberry Jam Big Birthday Weekend T-shirt, sits at a table with a robot arm, a laptop with a Pi sticker and other components. He is making an adjustment to his set-up.

Loïc showcases the prototype robot arm he built

There was lots more too, with others discussing their own Pi projects and talking about the possibilities Raspberry Pi offers, including a Pi-controlled drone and car. Cake was a prevailing theme of the Raspberry Jam Big Birthday Weekend around the world, and Raspberry Jam Camer made sure they didn’t miss out.

A round pink-iced cake decorated with the words "Happy Birthday RBP" and six candles, on a table beside Raspberry Pi stickers, Raspberry Jam stickers and Raspberry Jam fliers

Yay, birthday cake!!

A big success

Most visitors to the Jam were secondary school students, while others were university students and graduates. The majority were unfamiliar with Raspberry Pi, but all wanted to learn about Raspberry Pi and what they could do with it. Damien comments that the fact most people were new to Raspberry Pi made the event more interactive rather than creating any challenges, because the visitors were all interested in finding out about the little computer. The Jam was an all-round success, and the team was pleased with how it went:

What I liked the most was that we sensitized several people about the Raspberry Pi and what one can be capable of with such a small but powerful device. — Damien Doumer

The Jam team rounded off the event by announcing that this was the start of a Raspberry Pi community in Yaoundé. They hope that they and others will be able to organise more Jams and similar events in the area to spread the word about what people can do with Raspberry Pi, and to help them realise their ideas.

Raspberry Jam Camer gets the thumbs-up

The Raspberry Pi community in Cameroon

In a French-language interview about their Jam, the team behind Raspberry Jam Camer said they’d like programming to become the third official language of Cameroon, after French and English; their aim is to to popularise programming and digital making across Cameroonian society. Neither of these fields is very familiar to most people in Cameroon, but both are very well aligned with the country’s ambitions for development. The team is conscious of the difficulties around the emergence of information and communication technologies in the Cameroonian context; in response, they are seizing the opportunities Raspberry Pi offers to give children and young people access to modern and constantly evolving technology at low cost.

Thanks to Lionel, Eyong, Damien, and Loïc, and to everyone who helped put on a Jam for the Big Birthday Weekend! Remember, anyone can start a Jam at any time — and we provide plenty of resources to get you started. Check out the Guidebook, the Jam branding pack, our specially-made Jam activities online (in multiple languages), printable worksheets, and more.

ISP Telenor Will Block The Pirate Bay in Sweden Without a Shot Fired

Post Syndicated from Andy original https://torrentfreak.com/isp-telenor-will-block-the-pirate-bay-in-sweden-without-a-shot-fired-180520/

Back in 2014, Universal Music, Sony Music, Warner Music, Nordisk Film and the Swedish Film Industry filed a lawsuit against Bredbandsbolaget, one of Sweden’s largest ISPs.

The copyright holders asked the Stockholm District Court to order the ISP to block The Pirate Bay and streaming site Swefilmer, claiming that the provider knowingly facilitated access to the pirate platforms and assisted their pirating users.

Soon after the ISP fought back, refusing to block the sites in a determined response to the Court.

“Bredbandsbolaget’s role is to provide its subscribers with access to the Internet, thereby contributing to the free flow of information and the ability for people to reach each other and communicate,” the company said in a statement.

“Bredbandsbolaget does not block content or services based on individual organizations’ requests. There is no legal obligation for operators to block either The Pirate Bay or Swefilmer.”

In February 2015 the parties met in court, with Bredbandsbolaget arguing in favor of the “important principle” that ISPs should not be held responsible for content exchanged over the Internet, in the same way the postal service isn’t responsible for the contents of an envelope.

But with TV companies SVT, TV4 Group, MTG TV, SBS Discovery and C More teaming up with the IFPI alongside Paramount, Disney, Warner and Sony in the case, Bredbandsbolaget would need to pull out all the stops to obtain victory. The company worked hard and initially the news was good.

In November 2015, the Stockholm District Court decided that the copyright holders could not force Bredbandsbolaget to block the pirate sites, ruling that the ISP’s operations did not amount to participation in the copyright infringement offenses carried out by some of its ‘pirate’ subscribers.

However, the case subsequently went to appeal, with the brand new Patent and Market Court of Appeal hearing arguments. In February 2017 it handed down its decision, which overruled the earlier ruling of the District Court and ordered Bredbandsbolaget to implement “technical measures” to prevent its customers accessing the ‘pirate’ sites through a number of domain names and URLs.

With nowhere left to go, Bredbandsbolaget and owner Telenor were left hanging onto their original statement which vehemently opposed site-blocking.

“It is a dangerous path to go down, which forces Internet providers to monitor and evaluate content on the Internet and block websites with illegal content in order to avoid becoming accomplices,” they said.

In March 2017, Bredbandsbolaget blocked The Pirate Bay but said it would not give up the fight.

“We are now forced to contest any future blocking demands. It is the only way for us and other Internet operators to ensure that private players should not have the last word regarding the content that should be accessible on the Internet,” Bredbandsbolaget said.

While it’s not clear whether any additional blocking demands have been filed with the ISP, this week an announcement by Bredbandsbolaget parent company Telenor revealed an unexpected knock-on effect. Seemingly without a single shot being fired, The Pirate Bay will now be blocked by Telenor too.

The background lies in Telenor’s acquisition of Bredbandsbolaget back in 2005. Until this week the companies operated under separate brands but will now merge into one entity.

“Telenor Sweden and Bredbandsbolaget today take the final step on their joint trip and become the same company with the same name. As a result, Telenor becomes a comprehensive provider of broadband, TV and mobile communications,” the company said in a statement this week.

“Telenor Sweden and Bredbandsbolaget have shared both logo and organization for the last 13 years. Today, we take the last step in the relationship and consolidate the companies under the same name.”

Up until this final merger, 600,000 Bredbandsbolaget broadband customers were denied access to The Pirate Bay. Now it appears that Telenor’s 700,000 fiber and broadband customers will be affected too. The new single-brand company says it has decided to block the notorious torrent site across its entire network.

“We have not discontinued Bredbandsbolaget, but we have merged Telenor and Bredbandsbolaget and become one,” the company said.

“When we share the same network, The Pirate Bay is blocked by both Telenor and Bredbandsbolaget and there is nothing we plan to change in the future.”

TorrentFreak contacted the PR departments of both Telenor and Bredbandsbolaget requesting information on why a court order aimed at only the latter’s customers would now affect those of the former too, more than doubling the blockade’s reach. Neither company responded which leaves only speculation as to its motives.

On the one hand, the decision to voluntarily implement an expanded blockade could perhaps be viewed as a little unusual given how much time, effort and money has been invested in fighting web-blockades in Sweden.

On the other, the merger of the companies may present legal difficulties as far as the court order goes and it could certainly cause friction among the customer base of Telenor if some customers could access TPB, and others could not.

In any event, the legal basis for web-blocking on copyright infringement grounds was firmly established last year at the EU level, which means that Telenor would lose any future legal battle, should it decide to dig in its heels. On that basis alone, the decision to block all customers probably makes perfect commercial sense.

UK soldiers design Raspberry Pi bomb disposal robot

Post Syndicated from Helen Lynn original https://www.raspberrypi.org/blog/uk-soldiers-design-raspberry-pi-bomb-disposal-robot/

Three soldiers in the British Army have used a Raspberry Pi to build an autonomous robot, as part of their Foreman of Signals course.

Meet The Soldiers Revolutionising Bomb Disposal

Three soldiers from Blandford Camp have successfully designed and built an autonomous robot as part of their Foreman of Signals Course at the Dorset Garrison.

Autonomous robots

Forces Radio BFBS carried a story last week about Staff Sergeant Jolley, Sergeant Rana, and Sergeant Paddon, also known as the “Project ROVER” team. As part of their Foreman of Signals training, their task was to design an autonomous robot that can move between two specified points, take a temperature reading, and transmit the information to a remote computer. The team comments that, while semi-autonomous robots have been used as far back as 9/11 for tasks like finding people trapped under rubble, nothing like their robot and on a similar scale currently exists within the British Army.

The ROVER buggy

Their build is named ROVER, which stands for Remote Obstacle aVoiding Environment Robot. It’s a buggy that moves on caterpillar tracks, and it’s tethered; we wonder whether that might be because it doesn’t currently have an on-board power supply. A demo shows the robot moving forward, then changing its path when it encounters an obstacle. The team is using RealVNC‘s remote access software to allow ROVER to send data back to another computer.

Applications for ROVER

Dave Ball, Senior Lecturer in charge of the Foreman of Signals course, comments that the project is “a fantastic opportunity for [the team] to, even only halfway through the course, showcase some of the stuff they’ve learnt and produce something that’s really quite exciting.” The Project ROVER team explains that the possibilities for autonomous robots like this one are extensive: they include mine clearance, bomb disposal, and search-and-rescue campaigns. They point out that existing semi-autonomous hardware is not as easy to program as their build. In contrast, they say, “with the invention of the Raspberry Pi, this has allowed three very inexperienced individuals to program a robot very capable of doing these things.”

We make Raspberry Pi computers because we want building things with technology to be as accessible as possible. So it’s great to see a project like this, made by people who aren’t techy and don’t have a lot of computing experience, but who want to solve a problem and see that the Pi is an affordable and powerful tool that can help.

Police Arrest Suspected Member of TheDarkOverlord Hacking Group

Post Syndicated from Andy original https://torrentfreak.com/police-arrest-suspected-member-of-the-dark-overlord-hacking-group-180517/

In April 2017, the first episode of the brand new season of Netflix’s Orange is the New Black was uploaded to The Pirate Bay, months ahead of its official release date.

The leak was the work of a hacking entity calling itself TheDarkOverlord (TDO). One of its members had contacted TorrentFreak months earlier claiming that the content was in its hands but until the public upload, nothing could be confirmed.

TDO told us it had obtained the episodes after hacking the systems of Hollywood-based Larson Studios, an ADR (additional dialogue recorded) studio, back in 2016. TDO had attempted to blackmail the company into paying a bitcoin ransom but when it wasn’t forthcoming, TDO pressed the nuclear button.

Netflix responded by issuing a wave of takedown notices but soon TDO moved onto a new target. In June 2017, TDO followed up on an earlier threat to leak content owned by ABC.

But while TDO was perhaps best known for its video-leaking exploits, the group’s core ‘business’ was hacking what many perceived to be softer targets. TDO ruthlessly slurped confidential data from weakly protected computer systems at medical facilities, private practices, and businesses large and small.

In each case, the group demanded ransoms in exchange for silence and leaked sensitive data to the public if none were paid. With dozens of known targets, TDO found itself at the center of an international investigation, led by the FBI. That now appears to have borne some fruit, with the arrest of an individual in Serbia.

Serbian police say that members of its Ministry of Internal Affairs, Criminal Police Directorate (UCC), in coordination with the Special Prosecution for High-Tech Crime, have taken action against a suspected member of TheDarkOverlord group.

Police say they tracked down a Belgrade resident, who was arrested and taken into custody. Identified only by the initials “S.S”, police say the individual was born in 1980 but have released no further personal details. A search of his apartment and other locations led to the seizure of items of digital equipment.

“According to the order of the Special Prosecutor’s Office for High-Tech Crime, criminal charges will be brought against him because of the suspicion that he committed the criminal offense of unauthorized access to a protected computer, computer networks and electronic processing, and the criminal offense of extortion,” a police statement reads.

In earlier correspondence with TF, the TDO member always gave the impression of working as part of a team but we only had a single contact point which appeared to be the same person. However, Serbian authorities say the larger investigation is aimed at uncovering “a large number of people” who operate under the banner of “TheDarkOverlord”.

Since June 2016, the group is said to have targeted at least 50 victims while demanding bitcoin ransoms to avoid disclosure of their content. Serbian authorities say that on the basis of available data, TDO received payments of more than $275,000.

AWS IoT 1-Click – Use Simple Devices to Trigger Lambda Functions

Post Syndicated from Jeff Barr original https://aws.amazon.com/blogs/aws/aws-iot-1-click-use-simple-devices-to-trigger-lambda-functions/

We announced a preview of AWS IoT 1-Click at AWS re:Invent 2017 and have been refining it ever since, focusing on simplicity and a clean out-of-box experience. Designed to make IoT available and accessible to a broad audience, AWS IoT 1-Click is now generally available, along with new IoT buttons from AWS and AT&T.

I sat down with the dev team a month or two ago to learn about the service so that I could start thinking about my blog post. During the meeting they gave me a pair of IoT buttons and I started to think about some creative ways to put them to use. Here are a few that I came up with:

Help Request – Earlier this month I spent a very pleasant weekend at the HackTillDawn hackathon in Los Angeles. As the participants were hacking away, they occasionally had questions about AWS, machine learning, Amazon SageMaker, and AWS DeepLens. While we had plenty of AWS Solution Architects on hand (decked out in fashionable & distinctive AWS shirts for easy identification), I imagined an IoT button for each team. Pressing the button would alert the SA crew via SMS and direct them to the proper table.

Camera ControlTim Bray and I were in the AWS video studio, prepping for the first episode of Tim’s series on AWS Messaging. Minutes before we opened the Twitch stream I realized that we did not have a clean, unobtrusive way to ask the camera operator to switch to a closeup view. Again, I imagined that a couple of IoT buttons would allow us to make the request.

Remote Dog Treat Dispenser – My dog barks every time a stranger opens the gate in front of our house. While it is great to have confirmation that my Ring doorbell is working, I would like to be able to press a button and dispense a treat so that Luna stops barking!

Homes, offices, factories, schools, vehicles, and health care facilities can all benefit from IoT buttons and other simple IoT devices, all managed using AWS IoT 1-Click.

All About AWS IoT 1-Click
As I said earlier, we have been focusing on simplicity and a clean out-of-box experience. Here’s what that means:

Architects can dream up applications for inexpensive, low-powered devices.

Developers don’t need to write any device-level code. They can make use of pre-built actions, which send email or SMS messages, or write their own custom actions using AWS Lambda functions.

Installers don’t have to install certificates or configure cloud endpoints on newly acquired devices, and don’t have to worry about firmware updates.

Administrators can monitor the overall status and health of each device, and can arrange to receive alerts when a device nears the end of its useful life and needs to be replaced, using a single interface that spans device types and manufacturers.

I’ll show you how easy this is in just a moment. But first, let’s talk about the current set of devices that are supported by AWS IoT 1-Click.

Who’s Got the Button?
We’re launching with support for two types of buttons (both pictured above). Both types of buttons are pre-configured with X.509 certificates, communicate to the cloud over secure connections, and are ready to use.

The AWS IoT Enterprise Button communicates via Wi-Fi. It has a 2000-click lifetime, encrypts outbound data using TLS, and can be configured using BLE and our mobile app. It retails for $19.99 (shipping and handling not included) and can be used in the United States, Europe, and Japan.

The AT&T LTE-M Button communicates via the LTE-M cellular network. It has a 1500-click lifetime, and also encrypts outbound data using TLS. The device and the bundled data plan is available an an introductory price of $29.99 (shipping and handling not included), and can be used in the United States.

We are very interested in working with device manufacturers in order to make even more shapes, sizes, and types of devices (badge readers, asset trackers, motion detectors, and industrial sensors, to name a few) available to our customers. Our team will be happy to tell you about our provisioning tools and our facility for pushing OTA (over the air) updates to large fleets of devices; you can contact them at [email protected].

AWS IoT 1-Click Concepts
I’m eager to show you how to use AWS IoT 1-Click and the buttons, but need to introduce a few concepts first.

Device – A button or other item that can send messages. Each device is uniquely identified by a serial number.

Placement Template – Describes a like-minded collection of devices to be deployed. Specifies the action to be performed and lists the names of custom attributes for each device.

Placement – A device that has been deployed. Referring to placements instead of devices gives you the freedom to replace and upgrade devices with minimal disruption. Each placement can include values for custom attributes such as a location (“Building 8, 3rd Floor, Room 1337”) or a purpose (“Coffee Request Button”).

Action – The AWS Lambda function to invoke when the button is pressed. You can write a function from scratch, or you can make use of a pair of predefined functions that send an email or an SMS message. The actions have access to the attributes; you can, for example, send an SMS message with the text “Urgent need for coffee in Building 8, 3rd Floor, Room 1337.”

Getting Started with AWS IoT 1-Click
Let’s set up an IoT button using the AWS IoT 1-Click Console:

If I didn’t have any buttons I could click Buy devices to get some. But, I do have some, so I click Claim devices to move ahead. I enter the device ID or claim code for my AT&T button and click Claim (I can enter multiple claim codes or device IDs if I want):

The AWS buttons can be claimed using the console or the mobile app; the first step is to use the mobile app to configure the button to use my Wi-Fi:

Then I scan the barcode on the box and click the button to complete the process of claiming the device. Both of my buttons are now visible in the console:

I am now ready to put them to use. I click on Projects, and then Create a project:

I name and describe my project, and click Next to proceed:

Now I define a device template, along with names and default values for the placement attributes. Here’s how I set up a device template (projects can contain several, but I just need one):

The action has two mandatory parameters (phone number and SMS message) built in; I add three more (Building, Room, and Floor) and click Create project:

I’m almost ready to ask for some coffee! The next step is to associate my buttons with this project by creating a placement for each one. I click Create placements to proceed. I name each placement, select the device to associate with it, and then enter values for the attributes that I established for the project. I can also add additional attributes that are peculiar to this placement:

I can inspect my project and see that everything looks good:

I click on the buttons and the SMS messages appear:

I can monitor device activity in the AWS IoT 1-Click Console:

And also in the Lambda Console:

The Lambda function itself is also accessible, and can be used as-is or customized:

As you can see, this is the code that lets me use {{*}}include all of the placement attributes in the message and {{Building}} (for example) to include a specific placement attribute.

Now Available
I’ve barely scratched the surface of this cool new service and I encourage you to give it a try (or a click) yourself. Buy a button or two, build something cool, and let me know all about it!

Pricing is based on the number of enabled devices in your account, measured monthly and pro-rated for partial months. Devices can be enabled or disabled at any time. See the AWS IoT 1-Click Pricing page for more info.

To learn more, visit the AWS IoT 1-Click home page or read the AWS IoT 1-Click documentation.

From Framework to Function: Deploying AWS Lambda Functions for Java 8 using Apache Maven Archetype

Post Syndicated from Ryosuke Iwanaga original https://aws.amazon.com/blogs/compute/from-framework-to-function-deploying-aws-lambda-functions-for-java-8-using-apache-maven-archetype/

As a serverless computing platform that supports Java 8 runtime, AWS Lambda makes it easy to run any type of Java function simply by uploading a JAR file. To help define not only a Lambda serverless application but also Amazon API Gateway, Amazon DynamoDB, and other related services, the AWS Serverless Application Model (SAM) allows developers to use a simple AWS CloudFormation template.

AWS provides the AWS Toolkit for Eclipse that supports both Lambda and SAM. AWS also gives customers an easy way to create Lambda functions and SAM applications in Java using the AWS Command Line Interface (AWS CLI). After you build a JAR file, all you have to do is type the following commands:

aws cloudformation package 
aws cloudformation deploy

To consolidate these steps, customers can use Archetype by Apache Maven. Archetype uses a predefined package template that makes getting started to develop a function exceptionally simple.

In this post, I introduce a Maven archetype that allows you to create a skeleton of AWS SAM for a Java function. Using this archetype, you can generate a sample Java code example and an accompanying SAM template to deploy it on AWS Lambda by a single Maven action.

Prerequisites

Make sure that the following software is installed on your workstation:

  • Java
  • Maven
  • AWS CLI
  • (Optional) AWS SAM CLI

Install Archetype

After you’ve set up those packages, install Archetype with the following commands:

git clone https://github.com/awslabs/aws-serverless-java-archetype
cd aws-serverless-java-archetype
mvn install

These are one-time operations, so you don’t run them for every new package. If you’d like, you can add Archetype to your company’s Maven repository so that other developers can use it later.

With those packages installed, you’re ready to develop your new Lambda Function.

Start a project

Now that you have the archetype, customize it and run the code:

cd /path/to/project_home
mvn archetype:generate \
  -DarchetypeGroupId=com.amazonaws.serverless.archetypes \
  -DarchetypeArtifactId=aws-serverless-java-archetype \
  -DarchetypeVersion=1.0.0 \
  -DarchetypeRepository=local \ # Forcing to use local maven repository
  -DinteractiveMode=false \ # For batch mode
  # You can also specify properties below interactively if you omit the line for batch mode
  -DgroupId=YOUR_GROUP_ID \
  -DartifactId=YOUR_ARTIFACT_ID \
  -Dversion=YOUR_VERSION \
  -DclassName=YOUR_CLASSNAME

You should have a directory called YOUR_ARTIFACT_ID that contains the files and folders shown below:

├── event.json
├── pom.xml
├── src
│   └── main
│       ├── java
│       │   └── Package
│       │       └── Example.java
│       └── resources
│           └── log4j2.xml
└── template.yaml

The sample code is a working example. If you install SAM CLI, you can invoke it just by the command below:

cd YOUR_ARTIFACT_ID
mvn -P invoke verify

Maven automatically creates a shaded JAR file, uploads it to your S3 bucket, replaces template.yaml, and creates and updates the CloudFormation stack.

To customize the process, modify the pom.xml file. For example, to avoid typing values for awsRegion, s3Bucket or stackName, write them inside pom.xml and check in your VCS. Afterward, you and the rest of your team can deploy the function by typing just the following command:

mvn deploy

Options

Lambda Java 8 runtime has some types of handlers: POJO, Simple type and Stream. The default option of this archetype is POJO style, which requires to create request and response classes, but they are baked by the archetype by default. If you want to use other type of handlers, you can use handlerType property like below:

## POJO type (default)
mvn archetype:generate \
 ...
 -DhandlerType=pojo

## Simple type - String
mvn archetype:generate \
 ...
 -DhandlerType=simple

### Stream type
mvn archetype:generate \
 ...
 -DhandlerType=stream

See documentation for more details about handlers.

Also, Lambda Java 8 runtime supports two types of Logging class: Log4j 2 and LambdaLogger. This archetype creates LambdaLogger implementation by default, but you can use Log4j 2 if you want:

## LambdaLogger (default)
mvn archetype:generate \
 ...
 -Dlogger=lambda

## Log4j 2
mvn archetype:generate \
 ...
 -Dlogger=log4j2

If you use LambdaLogger, you can delete ./src/main/resources/log4j2.xml. See documentation for more details.

Conclusion

So, what’s next? Develop your Lambda function locally and type the following command: mvn deploy !

With this Archetype code example, available on GitHub repo, you should be able to deploy Lambda functions for Java 8 in a snap. If you have any questions or comments, please submit them below or leave them on GitHub.

Solving Complex Ordering Challenges with Amazon SQS FIFO Queues

Post Syndicated from Christie Gifrin original https://aws.amazon.com/blogs/compute/solving-complex-ordering-challenges-with-amazon-sqs-fifo-queues/

Contributed by Shea Lutton, AWS Cloud Infrastructure Architect

Amazon Simple Queue Service (Amazon SQS) is a fully managed queuing service that helps decouple applications, distributed systems, and microservices to increase fault tolerance. SQS queues come in two distinct types:

  • Standard SQS queues are able to scale to enormous throughput with at-least-once delivery.
  • FIFO queues are designed to guarantee that messages are processed exactly once in the exact order that they are received and have a default rate of 300 transactions per second.

As customers explore SQS FIFO queues, they often have questions about how the behavior works when messages arrive and are consumed. This post walks through some common situations to identify the exact behavior that you can expect. It also covers the behavior of message groups in depth and explains why message groups are key to understanding how FIFO queues work.

The simple case

Suppose that you run a major auction platform where people buy and sell a wide range of products. Your platform requires that transactions from buyers and sellers get processed in exactly the order received. Here’s how a FIFO queue helps you keep all your transactions in one straight flow.

A seller currently is holding an auction for a laptop, and three different bids are received for the same price. Ties are awarded to the first bidder at that price so it is important to track which arrived first. Your auction platform receives the three bids and sends them to a FIFO queue before they are processed.

Now observe how messages leave the queue. When your consumer asks for a batch of up to 10 messages, SQS starts filling the batch with the oldest message (bid A1). It keeps filling until either the batch is full or the queue is empty. In this case, the batch contains the three messages and the queue is now empty. After a batch has left the queue, SQS considers that batch of messages to be “in-flight” until the consumer either deletes them or the batch’s visibility timer expires.

 

When you have a single consumer, this is easy to envision. The consumer gets a batch of messages (now in-flight), does its processing, and deletes the messages. That consumer is then ready to ask for the next batch of messages.

The critical thing to keep in mind is that SQS won’t release the next batch of messages until the first batch has been deleted. By adding more messages to the queue, you can see more interesting behaviors. Imagine that a burst of 11 bids is sent to your FIFO queue, with two bids for Auction A arriving last.

The FIFO queue now has at least two batches of messages in it. When your single consumer requests the first batch of 10 messages, it receives a batch starting with B1 and ending with A1. Later, after the first batch has been deleted, the consumer can get the second batch of messages containing the final A2 message from the queue.

Adding complexity with multiple message groups

A new challenge arises. Your auction platform is getting busier and your dev team added a number of new features. The combination of increased messages and extra processing time for the new features means that a single consumer is too slow. The solution is to scale to have more consumers and process messages in parallel.

To work in parallel, your team realized that only the messages related to a single auction must be kept in order. All transactions for Auction A need to be kept in order and so do all transactions for Auction B. But the two auctions are independent and it does not matter which auctions transactions are processed first.

FIFO can handle that case with a feature called message groups. Each transaction related to Auction A is placed by your producer into message group A, and so on. In the diagram below, Auction A and Auction B each received three bid transactions, with bid B1 arriving first. The FIFO queue always keeps transactions within a message group in the order in which they arrived.

How is this any different than earlier examples? The consumer now gets the messages ordered by message groups, all the B group messages followed by all the A group messages. Multiple message groups create the possibility of using multiple consumers, which I explain in a moment. If FIFO can’t fill up a batch of messages with a single message group, FIFO can place more than one message group in a batch of messages. But whenever possible, the queue gives you a full batch of messages from the same group.

The order of messages leaving a FIFO queue is governed by three rules:

  1. Return the oldest message where no other message in the same message group is currently in-flight.
  2. Return as many messages from the same message group as possible.
  3. If a message batch is still not full, go back to rule 1.

To see this behavior, add a second consumer and insert many more messages into the queue. For simplicity, the delete message action has been omitted in these diagrams but it is assumed that all messages in a batch are processed successfully by the consumer and the batch is properly deleted immediately after.

In this example, there are 11 Group A and 11 Group B transactions arriving in interleaved order and a second consumer has been added. Consumer 1 asks for a group of 10 messages and receives 10 Group A messages. Consumer 2 then asks for 10 messages but SQS knows that Group A is in flight, so it releases 10 Group B messages. The two consumers are now processing two batches of messages in parallel, speeding up throughput and then deleting their batches. When Consumer 1 requests the next batch of messages, it receives the remaining two messages, one from Group A and one from Group B.

Consider this nuanced detail from the example above. What would happen if Consumer 1 was on a faster server and processed its first batch of messages before Consumer 2 could mark its messages for deletion? See if you can predict the behavior before looking at the answer.

If Consumer 2 has not deleted its Group B messages yet when Consumer 1 asks for the next batch, then the FIFO queue considers Group B to still be in flight. It does not release any more Group B messages. Consumer 1 gets only the remaining Group A message. Later, after Consumer 2 has deleted its first batch, the remaining Group B message is released.

Pirate IPTV Service Goes Bust After Premier League Deal, Exposing Users

Post Syndicated from Andy original https://torrentfreak.com/pirate-iptv-service-goes-bust-after-premier-league-deal-exposing-users-180913/

For those out of the loop, unauthorized IPTV services offering many thousands of unlicensed channels have been gaining in popularity in recent years. They’re relatively cheap, fairly reliable, and offer acceptable levels of service.

They are, however, a huge thorn in the side of rightsholders who are desperate to bring them to their knees. One such organization is the UK’s Premier League, which has been disrupting IPTV services over the past year, hoping they’ll shut down.

Most have simply ridden the wave of blocks but one provider, Ace Hosting in the UK, showed signs of stress last year, revealing that it would no longer sell new subscriptions. There was little doubt in most people’s minds that the Premier League had gotten uncomfortably close to the IPTV provider.

Now, many months later, the amazing story can be told. It’s both incredible and shocking and will leave many shaking their heads in disbelief. First up, some background.

Doing things ‘properly’ – incorporation of a pirate service…

Considering how most operators of questionable services like to stay in the shade, it may come as a surprise to learn that Ace Hosting Limited is a proper company. Incorporated and registered at Companies House on January 3, 2017, Ace has two registered directors – family team Ian and Judith Isaac.

In common with several other IPTV operators in the UK who are also officially registered with the authorities, Ace Hosting has never filed any meaningful accounts. There’s a theory that the corporate structure is basically one of convenience, one that allows for the handling of large volumes of cash while limiting liability. The downside, of course, is that people are often more easily identified, in part due to the comprehensive paper trail.

Thanks to what can only be described as a slow-motion train wreck, the Ace Hosting debacle is revealing a bewildering set of circumstances. Last December, when Ace said it would stop signing up new members due to legal pressure, a serious copyright threat had already been filed against it.

Premier League v Ace Hosting

Documents seen by TorrentFreak reveal that the Premier League sent legal threats to Ace Hosting on December 15, 2017, just days before the subscription closure announcement. Somewhat surprisingly, Ace apparently felt it could pay the Premier League a damages amount and keep on trading.

But early March 2018, with the Premier League threatening Ace with all kinds of bad things, the company made a strange announcement.

“The ISPs in the UK and across Europe have recently become much more aggressive in blocking our service while football games are in progress,” Ace said in a statement.

“In order to get ourselves off of the ISP blacklist we are going to black out the EPL games for all users (including VPN users) starting on Monday. We believe that this will enable us to rebuild the bypass process and successfully provide you with all EPL games.”

It seems doubtful that Ace really intended to thumb its nose at the Premier League but it had continued to sell subscriptions since receiving threats in December, so all things seemed possible. But on March 24 that all changed, when Ace effectively announced its closure.

Premier League 1, Ace Hosting 0

“It is with sorrow that we announce that we are no longer accepting renewals, upgrades to existing subscriptions or the purchase of new credits. We plan to support existing subscriptions until they expire,” the team wrote.

“EPL games including highlights continue to be blocked and are not expected to be reinstated before the end of the season.”

Indeed, just days later the Premier League demanded a six-figure settlement sum from Ace Hosting, presumably to make a lawsuit disappear. It was the straw that broke the camel’s back.

“When the proposed damages amount was received it was clear that the Company would not be able to cover the cost and that there was a very high probability that even with a negotiated settlement that the Company was insolvent,” documents relating to Ace’s liquidation read.

At this point, Ace says it immediately ceased trading but while torrent sites usually shut down and disappear into the night, Ace’s demise is now a matter of record.

Creditors – the good, the bad, and the ugly

On April 11, 2018, Ace’s directors contacted business recovery and insolvency specialists Begbies Traynor (Central) LLP to obtain advice on the company’s financial position. Begbies Traynor was instructed by Ace on April 23 and on May 8, Ace Hosting director Ian Isaac determined that his company could not pay its debts.

First the good news. According to an official report, Ace Hosting has considerable cash in the bank – £255,472.00 to be exact. Now the bad news – Ace has debts of £717,278.84. – the details of which are intriguing to say the least.

First up, Ace has ‘trade creditors’ to whom it owes £104,356. The vast majority of this sum is a settlement Ace agreed to pay to the Premier League.

“The directors entered into a settlement agreement with the Football Association Premier League Limited prior to placing the Company into liquidation as a result of a purported copyright infringement. However, there is a residual claim from the Football Association Premier League Limited which is included within trade creditors totaling £100,000,” Ace’s statement of affairs reads.

Bizarrely (given the nature of the business, at least) Ace also owes £260,000 to Her Majesty’s Revenue and Customs (HMRC) in unpaid VAT and corporation tax, which is effectively the government’s cut of the pirate IPTV business’s labors.

Former Ace Hosting subscriber? Your cash is as good as gone

Finally – and this is where things get a bit sweaty for Joe Public – there are 15,768 “consumer creditors”, split between ‘retail’ and ‘business’ customers of the service. Together they are owed a staggering £353,000.

Although the documentation isn’t explicit, retail customers appear to be people who have purchased an Ace IPTV subscription that still had time to run when the service closed down. Business customers seem likely to be resellers of the service, who purchased ‘credits’ and didn’t get time to sell them before Ace disappeared.

The poison chalice here is that those who are owed money by Ace can actually apply to get some of it back, but that could be extremely risky.

“Creditor claims have not yet been adjudicated but we estimate that the majority of customers who paid for subscription services will receive less than £3 if there is a distribution to unsecured creditors. Furthermore, customer details will be passed to the relevant authorities if there is any suggestion of unlawful conduct,” documentation reads.

We spoke with a former Ace customer who had this to say about the situation.

“It was generally a good service notwithstanding their half-arsed attempts to evade the EPL block. At its heart there were people who seemed to know how to operate a decent service, although the customer-facing side of things was not the greatest,” he said.

“And no, I won’t be claiming a refund. I went into it with my eyes fully open so I don’t hold anyone responsible, except myself. In any case, anyone who wants a refund has to complete a claim form and provide proof of ID (LOL).”

The bad news for former subscribers continues…potentially

While it’s likely that most people will forgo their £3, the bad news isn’t over for subscribers. Begbies Traynor is warning that the liquidators will decide whether to hand over subscribers’ personal details to the Premier League and/or the authorities.

In any event, sometime in the next couple of weeks the names and addresses of all subscribers will be made “available for inspection” at an address in Wiltshire for two days, meaning that any interested parties could potentially gain access to sensitive information.

The bottom line is that Ace Hosting is in the red to the tune of £461,907 and will eventually disappear into the bowels of history. Whether its operators will have to answer for their conduct will remain to be seen but it seems unimaginable at this stage that things will end well.

Subscribers probably won’t get sucked in but in a story as bizarre as this one, anything could yet happen.
