But as for how we can be fairly sure (not certain, granted) that this was the US government, well I think Occam's razor works here.
A php forum gets hacked and the simplest explanation you can think of is "NSA did it"? William of Ockham is facepalming in his grave.
Grow up. But as for how we can be fairly sure (not certain, granted) that this was the US government, well I think Occam's razor works here. Though another possibility is: we all know that the forum admins will have had to cooperate with the USG in some form to bring DPR down. Presumably some peeps with leet haxxor skillz won't have been happy with this, and possibly it was some form of retaliation. But I still think USG is most likely.
