U Vlad bro? Docker accidentally cuts off Ukraine

Did you know that US sanctions extend to the digital world too?


DevOps darling Docker accidentally cut off the entire country of Ukraine earlier this week following an overzealous effort to enforce US sanctions against Russia.

On Tuesday, the open platform's users based in the Eastern European country started posting to Docker's support forums complaining that they were hitting a block to Docker's AWS-powered download service. "The Amazon CloudFront distribution is configured to block access from your country," read a pop-up on one person's screen.

Others quickly figured out it was a geo-location ban targeting Ukrainian IP addresses and got around the block by using proxies reporting from outside the country. But the question remained as to why Docker had blocked its service in Ukraine.

And the answer, it emerged a few hours later, was renewed sanctions placed against Russia for its annexation of Crimea in 2014.

Late last month, the US Congress voted to expand existing sanctions and it appears as though those started being applied following the meeting between US president Trump and Russian president Putin at the recent G20 summit.

Trump has previously suggested he would lift the sanctions, but following the meeting it was clear that no agreement had been reached and Russian foreign minister Sergei Lavrov threatened that Russia would take its own actions against the US.

Reach

When it comes to sanctions, most people imagine it is only the refusal to sell weapons or fuel to a specific country, or freezing the accounts of individuals. But in reality they often extend much farther than that, and in the internet era often oblige companies under US legal control – ie, most internet services companies – to withdraw their services as well.

The only effective way of doing that is through geo-blocking, typically by identifying local ISPs and blacklisting their IP addresses. And so it was in this case, except that in trying to cut off Crimea, Docker's over-zealous tech team also managed to cut off the entire rest of the country – probably by relying too heavily on Amazon's blocking technology.

To its credit, Docker realized the error within a few hours of receiving the complaints, lifted the block and posted to its tech forum with an apology.

"Hey everyone, sorry for the trouble. The IP restrictions put in place per US embargo rules were too extensive. We've unblocked Ukraine now and I'm glad to see it's working properly again. Thanks for raising the issue!," wrote one employee. ®

  • Ransomware encrypts files, demands three good deeds to restore data
    Shut up and take ... poor kids to KFC?

    In what is either a creepy, weird spin on Robin Hood or something from a Black Mirror episode, we're told a ransomware gang is encrypting data and then forcing each victim to perform three good deeds before they can download a decryption tool.

    The so-called GoodWill ransomware group, first identified by CloudSEK's threat intel team, doesn't appear to be motivated by money. Instead, it is claimed, they require victims to do things such as donate blankets to homeless people, or take needy kids to Pizza Hut, and then document these activities on social media in photos or videos.

    "As the threat group's name suggests, the operators are allegedly interested in promoting social justice rather than conventional financial reasons," according to a CloudSEK analysis of the gang.

  • Microsoft Azure to spin up AMD MI200 GPU clusters for 'large scale' AI training
    Windows giant carries a PyTorch for chip designer and its rival Nvidia

    Microsoft Build Microsoft Azure on Thursday revealed it will use AMD's top-tier MI200 Instinct GPUs to perform “large-scale” AI training in the cloud.

    “Azure will be the first public cloud to deploy clusters of AMD's flagship MI200 GPUs for large-scale AI training,” Microsoft CTO Kevin Scott said during the company’s Build conference this week. “We've already started testing these clusters using some of our own AI workloads with great performance.”

    AMD launched its MI200-series GPUs at its Accelerated Datacenter event last fall. The GPUs are based on AMD’s CDNA2 architecture and pack 58 billion transistors and up to 128GB of high-bandwidth memory into a dual-die package.

  • Cheers ransomware hits VMware ESXi systems
    Now we can say extortionware has jumped the shark

    Another ransomware strain is targeting VMware ESXi servers, which have been the focus of extortionists and other miscreants in recent months.

    ESXi, a bare-metal hypervisor used by a broad range of organizations throughout the world, has become the target of such ransomware families as LockBit, Hive, and RansomEXX. The ubiquitous use of the technology, and the size of some companies that use it has made it an efficient way for crooks to infect large numbers of virtualized systems and connected devices and equipment, according to researchers with Trend Micro.

    "ESXi is widely used in enterprise settings for server virtualization," Trend Micro noted in a write-up this week. "It is therefore a popular target for ransomware attacks … Compromising ESXi servers has been a scheme used by some notorious cybercriminal groups because it is a means to swiftly spread the ransomware to many devices."

  • Twitter founder Dorsey beats hasty retweet from the board
    As shareholders sue the social network amid Elon Musk's takeover scramble

    Twitter has officially entered the post-Dorsey age: its founder and two-time CEO's board term expired Wednesday, marking the first time the social media company hasn't had him around in some capacity.

    Jack Dorsey announced his resignation as Twitter chief exec in November 2021, and passed the baton to Parag Agrawal while remaining on the board. Now that board term has ended, and Dorsey has stepped down as expected. Agrawal has taken Dorsey's board seat; Salesforce co-CEO Bret Taylor has assumed the role of Twitter's board chair. 

    In his resignation announcement, Dorsey – who co-founded and is CEO of Block (formerly Square) – said having founders leading the companies they created can be severely limiting for an organization and can serve as a single point of failure. "I believe it's critical a company can stand on its own, free of its founder's influence or direction," Dorsey said. He didn't respond to a request for further comment today.
