UPDATE2: It transpires that the outed member of Lulzsec isn't actually from Lulzsec - just as the person arrested in the UK, is only loosely related to the group (runs a messaging service that Lulzsec uses). While the announcements coincided with a communications blackout from Lulzsec, it now looks like the group is operating as normal and is bemused at all the media claims. Meanwhile TeamPoison hasn't yet released any details on Lulzsec's identities.

UPDATE1: One of the last known actions of Lulzsec has been added at the base of this article.

Hacking group TeamPoison has claimed it has hacked the notorious Lulzsec hacking group. A message was posted on an alleged Dutch Lulzsec member's website which has since been taken down. The group says it is planning to release names, addresses and pictures of the Lulzsec team.

The following was posted on this website:-

BREAKING NEWS: TEH LULZBOAT HAS OFFICALY SANK WITH 100S OF ANON MEMBERS ON BOARD!

No matter how many bots you gather, no matter how much people you lie to, no matter how much pre-made tools you use, you will _NEVER_ represent the real hacking scene, we warned you, we told you we do not make empty threats, we gave u 48hrs to secure your ircs yet u failed to do so, instead u posted hashes from public forums and then claimed you doxed us and laughed at the fact that i was 17years old. stop telling yourself that u are hackers, putting a ip into a irc is NOT hacking nor is using pre-made tools and scripts to grab databases... you do not represent the anti-sec movement, u are not allowed to greet underground groups like zf0, ab, h0n0, el8 like your member "AnonSabu" was doing, you will never be apart of the underground scene, if anyone thinks you are underground and can actually hack they have no idea about what happens in the underground scene. oh and TeaMp0isoN Issue 2 is coming out VERY soon exposing lulzsec members (pictures, addresses, passwords, ips, phone numbers etc). . . . not so anonymous anymore are you? lets hope that you can swim because the lulzboat just got titanic'd...

According to the report, "it seems they are taking down Lulzsec's IRC servers which means it wont be able to ddos anymore. It also appears anonnews' irc server is also down."

The following screen shot was also posted along with a video of Celine Dion singing the Titanic theme song.

Lulzsec were unavailable for comment.

UPDATE

Meanwhile, one of the last known actions of Lulzsec was apparently to hand over details of 'snitches' to the FBI. They said the following in a post on another site (names have been removed):

Hi FBI & other law enforcement clowns,

LulzSec here with some juicy gossip.

This is ****, also known as **** in the "#pure-elite" IRC logs you no doubt have enjoyed. He was involved in the hacking of the game "Dues Ex" and was/is involved in countless other cybercrimes.

Also, he tried to snitch on us. Therefore we just did your job for you with great ease.

This moron is trying to flee the country in order to avoid serious punishment. Hunt him down:

...

These goons begged us for mercy after they apologized to us all night for leaking some of our affiliates' logs. There is no mercy on The Lulz Boat.

Snitches get stitches,

Lulz Security
