Ransomware scripts in PyPI

Three of the listed packages are typosquatting attacks in Python. In this case, the attacker is mimicking the name of a widely known library called 'Requests', expecting that developers will accidentally download the malicious packages instead of the legitimate ones. If you're a developer and you don't type the correct name, there's a possibility that you end up downloading packages that contain ransomware scripts.

Read our blog post for more details.

For reference, here are the names of the malicious packages:

Sonatype's automated malware detection system that's offered as a part of Sonatype Platform products, including Sonatype Repository Firewall, helped us discover these packages.

Turn on Sonatype Repository Firewall for automatic protection

As a DevSecOps organization, we remain committed to identifying and halting attacks against open source developers and the wider software supply chain, like the ones discussed above.

Users of Sonatype Repository Firewall can rest easy knowing that such malicious packages would automatically be blocked from reaching their development builds.
