Welcome to the latest edition of The Week in Security, which brings you the newest headlines from both the world and our team across the full stack of security: application security, cybersecurity, and beyond. This week: another open-source platform is being used by cybercriminals. Also: the Black Basta ransomware gang takes credit for the attack on Maple Leaf Foods. 

This Week’s Top Story

Typosquatting and secrets leaks are plaguing Docker Hub repositories

Docker Hub, a cloud-based container library, has become another example of an open-source platform being taken advantage of cybercriminals. Bleeping Computer reports that the library has over 1,600 images hiding malicious behavior. The malicious properties hidden include cryptocurrency miners, secrets leaks being used as backdoors, DNS hijackers, and website redirectors, according to researchers at Sysdig. 

Many rely on Docker Hub to freely search for and download Docker images — templates for the simple creation of containers — from the platform’s public library. It also allows anyone to upload their creations to the public library, which is what these malicious actors have capitalized on. These cybercriminals have also used typosquatting — slightly changing the spelling of legitimate, safe images — to trick unaware users into downloading a malicious Docker image. 

Sysdig scanned 250,000 unverified Linux images, yielding 1,652 malicious results. Among the malicious images, the majority of them were crypto-miners, with the second largest category being hidden, embedded secrets. Images with the purpose of crypto-mining were designed with malicious intent by threat actors, meanwhile images containing secrets leaks could have been a result of an organization posting them publicly on accident. 

Similar to the security issues of open-source software repositories such as npm and PyPI, Docker Hub is struggling to keep an eye on its growing threat landscape. With the majority of images on the platform coming from public repositories, Docker Hub is unable to scrutinize every upload, leaving gaps in managing these kinds of threats.
