OK: After talking to two people with direct knowledge of how TLOU2 leaked as well as some Naughty Dog employees, I have a good idea of what happened. Short version: hackers found a security vulnerability in a patch for an older ND game and used it to get access to ND's servers.

“Okay, after talking to a couple of people with direct knowledge about TLOU2 leaks, as well as some Naughty Dog employees, I have a plausible idea of what happened. Short version: hackers found a vulnerability in a patch of an old Naughty Dog game and through that they managed to gain access to the ND servers " reads in post by Schreier.
“I think the leaked footage is from developers who were playing one of the game's initial builds (I haven't seen it). The most important thing is that the rumors relating to the fact that it was an act of protest of an employee who had been denied his salary, are not true. "
