Malicious code in mrmustard (PyPI)
-= Per source details. Do not edit below this line.=-
Versions 0.7.4 were compromised.
Compromised release has embedded code that during import exfiltrates sensitive data (selected environmental variables, credentials to AWS, SSH keys etc.) and ensures persistence via multiple ways: a cron entry, a malicious PTH file, and a shell configuration file. Persistence is diguished as "tensorflow hardware compatibility check" using file placed under ~/.cache/.tf_cache/hw_probe.pyc. The malicious version was uploaded after exfiltrating the PyPI token from the CI environment, likely after compromising the maintainer's Github account.
