I'm interested in figuring out what happened and more information on the contributor behind the attack.
Everybody keeps saying it was found by luck, but this seems like it was found by a guy who maintains his repository properly and monitors his CPU cycles diligently just to prevent this sort of thing. I guess I would call it lucky he found it so quickly, but it was definitely not found by luck.
It's more so lucky that there was someone diligently doing that. It could've easily gone unnoticed had there not been someone like him.
