Hackers took control of Gentoo Linux distribution’s GitHub account last week. Hackers gained administrative privileges for the project’s GitHub organisation after guessing the account password. Gentoo developers were unable to use GitHub for five days after the attack. The project got lucky that the attack was “loud,” as knocking all other developers out of the targeted account caused them to be emailed. It is not known who was behind the attack, but Gentoo has taken many actions to prevent such attacks in the future.
