Meet Hector Xavier Monsegur, better known as “Sabu,” the defacto leader of the hacking collective LulzSec, which made a name for itself with a number of high-profile incidents last year. Monsegur, a New York City resident, was actually pinpointed by the FBI in June. However, he did something pretty major — fearing jail time would separate him from his two young children, he reluctantly agreed to work with the FBI to take down other members of the LulzSec group, going so far as to reportedly work out of FBI offices to help. The takedown happened today, with five arrests taking place. Pretty crazy, right? You said it.
