Just after the hacker collectives LulzSec and Anonymous announced Operation Anti-Security, two groups of cyber-vigilantes have claimed to have unmasked several of LulzSec's members.

The reveals come from a self-described ex-miltary hacker working under the codename Th3j35t3r and a new group calling itself the Web Ninjas.

The two reportedly outed the code-names of certain LulzSec members after an unedited chat-log of a conversation between LulzSec members was posted to the Full Disclosure computer security mailing list.

LulzSec subsequently responded to the post on its Twitter feed indicating that the log was authentic. LulzSec reported that the log came from a compromised channel that was only used "to recruit talent for side-operations". It later clarified that its main channel was still secure.

The hacking collective went on to highlight how certain handles in the log were not actually those of LulzSec members -- meaning that those not mentioned probably are LulzSec members.

Cyber vigilante groups have since targeted those not mentioned. Specifically they have latched onto the "Kayla" handle that appeared in the log.

Kayla is the name of the former Anonymous contributer that gave an interview to Forbes magazine about his/her involvement in the group's attack on the security firm HBGary.

The user handle Topiary has also garnered significant attention. The handle is linked to an Anonymous contributor suspected of aiding the group's attacks on the Westboro Baptist Church.

The member is also believed to be the Anonymous representative that debated a church leader on the David Pakman show.

Many of the cyber vigilantes have pointed out that the voice on LulzSec's request line is remarkably similar to Topiary's voice, even having a similar European accent.

Web Ninjas have since posted photos and information regarding several other persons it believes to be LulzSec members.

On its website it has promised to shortly reveal the name, address and work location of a LulzSec member operating under the moniker "Sabu".

The news comes after LulzSec and Anonymous announced Operation Anti-Security. The new campaign is set to see the groups work together to target "any and all" government agencies and departments it comes across.

No law enforcement agency has yet commented on the cyber vigilante groups claims.

UPDATE: LulzSec has since hacked the U.K.'s Serious Organised Crime Agency.
