Today 28 June at approximately 20:20 UTC unknown individuals have gained
control of the Github Gentoo organization, and modified the content of
repositories as well as pages there. We are still working to determine the
exact extent and to regain control of the organization and its
All Gentoo code hosted on github should for the moment be considered
compromised. This does NOT affect any code hosted on the Gentoo
infrastructure. Since the master Gentoo ebuild repository is hosted on our
own infrastructure and since Github is only a mirror for it, you are fine
as long as you are using rsync or webrsync from gentoo.org.
Also, the gentoo-mirror repositories including metadata are hosted under a
separate Github organization and likely not affected as well.
All Gentoo commits are signed, and you should verify the integrity of the
signatures when using git.
More updates will follow.
