Hackers compromised one of the GitHub accounts used by the Gentoo Linux distribution and planted a malicious code. Hackers replaced the portage and musl-dev trees with malicious ebuilds intended to delete all files from a system. The malicious software could not work on GitHub and the development team has already removed it. GitHub has suspended the hacked account, users can verify the signature of the commits to stay secure. The code hosted on its own infrastructure is not impacted. The Gentoo repository mirrors are hosted in a separate GitHub account that were not affected.”]
