Hector Xavier Monsegur, a.k.a. Sabu, pleaded guilty to 12 counts of computer hacking conspiracies. The former leader of LulzSec pleaded guilty in exchange for assisting the FBI in catching other members of the group. He will now be sentenced on Feb. 22, 2013, instead, according to a new court filing from the U.S. District Attorney. Sabu has been out of the public view for months after his cover was blown as a federal informant.”]
