Fox is reporting that key memebrs of the group were arrested earlier today. It seems that the hacker in charge, Hector Xavier Monsegur - better known as "Sabu" - of New York led the FBI to the other leading members of the organization.
Earlier today, Ryan Ackroyd ("Kayla") and Jake Davis ("Topiary") were arrested in London, Darren Martyn ("Pwnsauce") and Donncha O’Cearrbhail ("Palladium") were arrested in Ireland and Jeremy Hammond ("Anarchaos") was arrested in Chicago. The FBI filed conspiracy charges against all five suspects. Sabu pleaded guilty to 12 related hacking charges in August of last year.
“This is devastating to the organization,” an FBI official told Fox. “We’re chopping off the head of LulzSec.”
The loosely organized hacker group is believed to potentially include thousands of hackers.
In a somewhat surprising event, Fox reports that Sabu has turned against his former co-hackers, has become a "cooperating witness" and "now works for the FBI". As a result, the FBI was able to file additional charges against the five hackers arrested earlier today. Jeremy Hammond was hit with access device fraud and hacking charges, as he is believed to be the main hacker behind hack on Stratfor. Ryan Ackroyd is described as Monsegur's deputy and the person who found vulnerabilities in the U.S. Senate’s computer systems.
