LulzSec—the notorious hacking group responsible for breaching government and corporate security systems—called it quits on Saturday, PC World reports. The group relayed a message to its 281, 870 Twitter followers, saying that their hacking operations were finished, before releasing private data obtained in the last two months from the CIA, U.S. Senate, Sony, and AOL. LulzSec encouraged followers to shift their attention to former rival hackers, Anonymous, who are also implicated in the Sony PlayStation Service hack that occurred earlier this year.
