Hackers collective LulzSec, after terrorizing the Internet community and giving top companies and government agencies sleepless nights, has finally called it quits even as rival hack group TeaMp0isoN has reared its head.

The group, which carried on a hacking assault for the last 50 days, in a Pastebin.com post said it's time to say bon voyage.

Today marks something meaningful to us. 50 days ago, we set sail with our humble ship on an uneasy and brutal ocean: the Internet. The hate machine, the love machine, the machine powered by many machines. We are all part of it, helping it grow, and helping it grow on us, LulzSec wrote.

For the past 50 days we've been disrupting and exposing corporations, governments, often the general population itself, and quite possibly everything in between, just because we could. All to selflessly entertain others - vanity, fame, recognition, all of these things are shadowed by our desire for that which we all love. The raw, uninterrupted, chaotic thrill of entertainment and anarchy. It's what we all crave, even the seemingly lifeless politicians and emotionless, middle-aged self-titled failures. You are not failures. You have not blown away. You can get what you want and you are worth having it, believe in yourself.

While we are responsible for everything that The Lulz Boat is, we are not tied to this identity permanently. Behind this jolly visage of rainbows and top hats, we are people. People with a preference for music, a preference for food; we have varying taste in clothes and television, we are just like you. Even Hitler and Osama Bin Laden had these unique variations and style, and isn't that interesting to know? The mediocre painter turned supervillain liked cats more than we did.

Again, behind the mask, behind the insanity and mayhem, we truly believe in the AntiSec movement. We believe in it so strongly that we brought it back, much to the dismay of those looking for more anarchic lulz. We hope, wish, even beg, that the movement manifests itself into a revolution that can continue on without us. The support we've gathered for it in such a short space of time is truly overwhelming, and not to mention humbling. Please don't stop. Together, united, we can stomp down our common oppressors and imbue ourselves with the power and freedom we deserve.

So with those last thoughts, it's time to say bon voyage. Our planned 50 day cruise has expired, and we must now sail into the distance, leaving behind - we hope - inspiration, fear, denial, happiness, approval, disapproval, mockery, embarrassment, thoughtfulness, jealousy, hate, even love. If anything, we hope we had a microscopic impact on someone, somewhere. Anywhere.

Thank you for sailing with us. The breeze is fresh and the sun is setting, so now we head for the horizon.

Let it flow...

Lulz Security - our crew of six wishes you a happy 2011, and a shout-out to all of our battlefleet members and supporters across the globe, the hack group wrote.

LulzSec's latest message came as a shock to the Internet community because everybody had expected LulzSec to carry out Operation: Anti-Security as it had announced last week.

The group, which had recently infiltrated the websites and networks of Sony, PBS, the US Senate, the CIA, and a slew of gaming sites popular with 4Chan users including EVE Online, Minecraft and League of Legends, had teamed up with another hacker group Anonymous, which is an infamous hacker group, which routinely has taken up politically- and morally-charged causes, to launch 'Operation Anti-Security' or 'AntiSec' to expose corrupt, abusive governments by protesting and combating any and all institutions' or governments' attempts to censor or moderate the Internet.

“Top priority is to steal and leak any classified government information, including email spools and documentation. Prime targets are banks and other high-ranking establishments,” the group's operation statement read.

The first casualty was Arizona police website as LulzSec leaked dozens of internal documents over the Internet with the headlineChinga La Migra, Spanish for a more profane way of saying Screw the Immigration Service. The group said the leak was retaliation for Arizona’s controversial immigration bill that requires Arizona immigrants to carry registration documents at all times.

LulzSec also hacked into 2 Brazilian government websites - Brasil.gov.br and Presidencia.gov.br - that were both down after the hack.

Meanwhile, Anonymous posted the names of 2800 of the right-wing Columbian Black Eagles Special Police Unit's members online. The published data has been credited as part of it and LulzSec's ongoing Operation Anti-Security.

However, it seems not everybody shared LulzSec's philosophy.

Rival hack group TeaMp0isoN hacked into the website of an alleged LulzSec member Swen Slootweg (who goes by the handle Joepie91) and warned LulzSec to back down, telling them: you will_NEVER_represent the real hacking scene.

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 a part 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, TeaMp0isoN said.

TeaMp0isoN, which compose of TriCk aka Saywhat? & iN^SaNe, also warned that unless LulzSec backs down, it will make public all the information on LulzSec members. On Friday, TeaMp0isoN posted in Pastebin what appeared to be the address book and other private data of former British Prime Minister Tony Blair. The leak includes the names, phone numbers and addresses of numerous British politicians and personal contacts, as well as Blair’s National Insurance number, the equivalent of a Social Security Number in the US.

TeaMp0isoN said the trove of private data was originally stolen via a private exploit in December 2010.

When a Blair spokesman said the data was not obtained from Blair himself, but rather the personal email account of a former staffer, TeaMp0isoN member TriCk said “Blairs [sic] sheep are lying about how we got the info.”

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? Let’s hope that you can swim because the lulzboat just got titanic’d, it taunted.

Another hacker who goes by the alias Red_Penguin, told the hackers community not to heed LulzSec's 'AntiSec' call.

I am not promoting the purity and perfection of this government…But this Anti-Security operation is not the right answer. I suggest a #ProSec operation which does not damage the reputation of the Internet as a whole. Do not take up the Lulz Lizard banner and show how bad the Internet can be, but instead stand against those who are only damaging our interwebs which we live on and think for yourselves, Red_Penguin said.

Red_Penguin has posted a chat log between alleged LulzSec members and has provided a link to the infamous Th3j35t3r's website. Th3j35t3r is allegedly a hackers group with anti-LulzSec sentiments.

Earlier, Web Ninjas, a supposed hacker vigilantes with possible ties to Th3j35t3r, had exposed the alleged identities of LulzSec members by posting up the IRC chat logs and personal information on many LulzSec members including Kayla, Topiary, Joepie and many others.

Web Ninjas said they also have the information of the LulzSec leader, including his name, address, location, photo, etc and are waiting for the right time to hand over the sensitive data to the FBI. “Game over for you Guys,” Web Ninjas boasted, adding that we have shown them that they are not the ‘Internet Gods’ they think they are.

The government authorities were also hot on LulzSec's trial.

On Tuesday, a 19-year old man called Ryan Cleary, with alleged links to LulzSec, was arrested by the London Metropolitan Police's Central e-Crime Unit. LulzSec, however, has denied that Cleary is part of the group. Ryan Cleary is not part of LulzSec; we house one of our many legitimate chatrooms on his IRC server, but that's it, the hack group tweeted last night. We use Ryan's server, we also use Efnet, 2600, Rizon and AnonOps IRC servers. That doesn't mean they're all part of our group.

Is this the end of LulzSec's dream run? Has the Lulz boat finally sailed into the sunset? Is TeaMp0isoN the new hack group that will terrorize the Internet community? Leave your comments below.
