Notorious hackers collectives LulzSec (Lulz Security) and Anonymous have teamed up, promising to attack corrupt and oppressive governments and expose them via Operation Anti-Security.

The two groups announced, Sunday, that they said they will attack any government websites or systems. At the same time, they invited other hacker groups, no matter white, black or gray, to join in this assault.

...the government and whitehat security terrorists across the world continue to dominate and control our Internet ocean. Sitting pretty on cargo bays full of corrupt booty, they think it's acceptable to condition and enslave all vessels in sight. Our Lulz Lizard battle fleet is now declaring immediate and unremitting war on the freedom-snatching moderators of 2011, LulzSec said in a statement posted on Pastebin.

“Welcome to Operation Anti-Security,” the statement, widely publicized in Tweeter, said. “We encourage any vessel, large or small, to open fire on any government or agency that crosses their path. We fully endorse the flaunting of the word 'AntiSec' on any government website defacement or physical graffiti art.”

To intensify efforts and make the operation a success, LulzSec said they are now teaming up with the Anonymous collective and all affiliated battleships.

About their goals, the statement read “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.”

If they try to censor our progress, we will obliterate the censor with cannon fire anointed with lizard blood, the group said.

LulzSec hasn't forgotten to clarify their motivation: the groups said their attacks are not motivated by financial gains or reason. Just simply “to have fun by causing mayhem,” they said.

This is the first time perhaps a cyber attack on a global scale has been publicly announced. Incidentally, the announcement came just days after the U.S. government said it will take steps to crush cyberterrorism, which it views as an act of war. If the new law is passed by the government, hackers who are caught and convicted of damaging government systems, can face prison for up to 20 years.

Recently, LulzSec had claimed credit for recent attacks on Sony, Nintendo, Bethesda, The Escapist, PBS, Fox.com, the US Senate, the CIA, and a slew of gaming sites including EVE Online, Minecraft and League of Legends.

Anonymous is an infamous hacker group, which routinely has taken up politically- and morally-charged causes.
