Reports indicate that hacking group Lulz Security, commonly known as "Lulzsec," has been betrayed by its leader. 28 year-old New Yorker Hector Xavier Monsegur, known online as "Sabu," has apparently been working with the FBI for months to bring down his own buddies. These efforts have culminated in "a string of arrests" today in the United States, England, and Ireland. Lulzsec was responsible for cyber attacks on Sony Pictures, the CIA, and senate.gov, along with a number of video game-related websites. They are an offshoot of the larger worldwide hacking group Anonymous.
