As it marks 1,000 tweets with a declaration of what it has and wants to achieve, there is no doubt that the actions of LulzSec are to be taken very seriously.

However it seems that over the weekend the mask of LulzSec has dropped slightly to reveal its members. A blog site appeared, named http://lulzsecexposed.blogspot.com/ that named the various members as Sabu, Nakomis, Topiary, Tflow, Kayla, Joepie91, Avunit and BarrettBrown.

According to an Imperva blog, Sabu was responsible for the hacking of HBGary and is the leader, Nakomis is a coder, Topiary handles donations and payment for services including botnets. Tflow and Kayla are rumoured hackers; Joepie91 is responsible for website administration, while BarrettBrown is the spokesperson, although he later denied this and said that he does not approve of Lulzsec's activities.. Full details can be found on the members from the exposed website.

Interestingly, Nakomis has also used the Twitter handle ‘real_j35t3r', as opposed to hacker ‘The Jester' (th3j35t3r) and has been exposed as Casey Gardiner. A social networking profile from 2004 also seemed to confirm this.

The Jester, who posted a detailed investigation blog on Nakomis/Gardner, said: “I am merely presenting relentless observations, having myself been hounded by these f***wits for months. As you will see if you read everything from the top.

“Let's not forget they went from lulz (mal-nourished basement dwellers) to terrorists around this time when they attacked CIA.gov and tried to extort Karim. You draw your own conclusions.”

LulzSec responded with a statement that acknowledged the logs, saying that the logs are primarily from a channel called ‘pure-elite', which is not the LulzSec core chatting channel.

“Pure-elite is where we gather potential backup/subcrew research and development battle fleet members, i.e. we were using that channel only to recruit talent for side-operations. Our core chatting channel remains unaffected. Our core LulzSec team is at full strength. The Lulz Boat sails stronger than ever, nice try though,” it said.

So even if those behind LulzSec have been identified, will it make much difference? Arguably not, as with any global online collective, those involved can assume new identities quickly and easily and new members and supporters will be drawn in constantly.
