After a spring of hacking and disruptive attacks on the likes of the CIA, BioWare, Sony, Nintendo, and Minecraft, LulzSec's reign of anonymity has ended in the high profile arrests of ringleader Sabu and five other leaders in Europe and the United States.
Apparently Sabu, IRL Hector Xavier Monsegur, was arrested last June by the FBI. Following his arrest Sabu gave up Ryan Ackroyd and Jake Davis of London, Darren Martyn and Donncha O'Cearrbhail of Ireland, and Jeremy Hammond of the US.
According to the FBI and FoxNews who broke the story, Sabu now works for the FBI. Who's going to tell them that LulzSec basically just went on a spree of DDoS attacks? How long will it take for the FBI to figure how to do that themselves?
