Is this confirmed? There is the message from somebody claiming to be the original contributer claiming to have been hacked, but that was weird (1 h old github account) so other scenarios seem possible
a) really a agent going off the rails
b) the contributer trying to cover up that he let an agent run wild and now made more misstakes along the way
So yes, it seems like an attack to me, but it is far from clear what really happened.

Without identifying and interviewing the attacker we can't confirm that's what they intended, and there's a possibility that it was just incompetence/ignorance/whatever, but we should probably treat it as an attempted attack even if it wasn't.
Someone's bug tracker account was hacked.
BTW, any idea what are the current requirements for creating a new GitHub account ? That could provide some information about if there was actually a person controlling thing thing at that moment to say provide wahtever was necessary to get the new GitHub account.
