After FBI agents raided a home in Hamilton, Ohio, on Monday, it came out that they were searching for a hacker associated with Lulz Security, the hactivist collective that disbanded last weekend after a 50-day campaign of mischief. The raid comes as flickers of tension and infighting among the group's former members have surfaced publicly online. It also follows the arrest and subsequent release on bail of a teenager said to be a key member of LulzSec, but whom the group says was "at best, a mild associate." Meanwhile, LulzSec itself has tried to out some of its former members who it says wronged it, while others online try to identify the group's key players. In other words: LulzSec's enemies are becoming a problem. The story lines of the group's many detractors are a bit tricky to unravel, but here's a partial list of outside enemies trying to expose LulzSec members as well as insiders who have turned on them:

The Jester: Known on Twitter as @th3J35t3r, he is a former military hacker who has been feuding with LulzSec on Twitter since the group first became active. Last week, the Jester claimed on Twitter to have outed the group in a pastebin posting. He also has a Wordpress blog where he details evidence of the identities of its members. He works alone and LulzSec hates his guts. The group posted a screed against him on Pastebin before it ceased operation. The Jester usually targets higher-profile terrorists, and is suspected in yesterday's takedown of al Qaeda's Web site.
