NEW YORK (AP) — A group of expert hackers who attacked governments and corporations around the globe has been busted after its ringleader — one of the world’s most-wanted and most-feared computer vandals — turned against his comrades and secretly became an informant for the FBI months ago, authorities said Tuesday.
Five people, including a Chicago man, were charged in court papers unsealed in federal court in New York, and authorities revealed that a sixth person, Hector Xavier Monsegur, a legendary figure known in the hacking underworld as “Sabu,” has pleaded guilty in New York, where he lives.
Authorities said it marked the first significant prosecution of major Internet hackers.
According to court papers, members of the group got their start as part of a large worldwide hacking organization known as Anonymous, which authorities said has been operating at least since 2008. Court papers accused Anonymous of a “deliberate campaign of online destruction, intimidation and criminality.”
In chat rooms and on Twitter, Anonymous supporters erupted into a chorus of disappointment, confusion, and anger. Some wondered whether the news was an elaborate fraud. Others revisited earlier suspicions that Sabu was a government agent.
As members of Anonymous surveyed the damage Tuesday, one of its most popular Twitter feeds assured its followers that it was still OK. “We’re sailing close to the wind,” the feed read. “Our crew is complete and doing fine.”
Monsegur was portrayed in court papers as the ringleader of some of the group’s more infamous deeds. Authorities said he formed an elite hacking organization last May — a spinoff of Anonymous — and named it “Lulz Security” or “LulzSec.” “Lulz” is Internet slang that can mean “laughs” or “amusement.”
Despite the organization’s lighthearted name, authorities said Monsegur and his followers embarked on a dastardly stream of deeds against business and government entities in the U.S. and around the world, resulting in the theft of confidential information, the defacing of websites and victims being temporarily put out of business. Authorities said their crimes affected nearly 1 million people.
Their exploits included attacks on cyber-security firms and the posting of a fake story that slain rapper Tupac Shakur was alive in New Zealand. As their exploits became known, some hackers associated with the group boasted about their prowess.
Monsegur, free on $50,000 bail, was charged with conspiracy to engage in computer hacking, among other offenses. Authorities said he pleaded guilty Aug. 15. Word of his cooperation was contained in court records.
According to the court papers, he was an influential member of three hacking organizations — Anonymous, Internet Feds and Lulz Security. Court papers said he acted as a “rooter,” a hacker who identified vulnerabilities in computer systems. The court papers said he participated in attacks over the past few years on Visa, MasterCard and PayPal; government computers in Tunisia, Algeria, Yemeni and Zimbabwe; Fox Broadcasting Co. and the Tribune Co.; PBS; and the U.S. Senate.
Also charged in court papers with conspiracy to commit computer hacking were Ryan Ackroyd, Jake Davis, Darren Martyn, Donncha O’Cearrbhail and Jeremy Hammond. Three were arrested Tuesday; Davis and Martin were previously arrested. Hammond, who is from Chicago, appeared before a federal judge there and was ordered transferred to New York. Martyn and O’Cearrbhail lived in Ireland, Ackroyd and Davis in Britain.
LulzSec members attained notoriety last May by attacking the PBS website and planting the false story about Shakur. According to court papers Tuesday, Monsegur and others did it in retaliation for what they perceived to be unfavorable news coverage of Wikileaks on the PBS news program “Frontline.”
In July, when LulzSec’s attacks were grabbing world headlines, an unknown person alleged that Sabu was Monsegur, publishing his personal details on the Internet. Sabu took to Twitter to deny that he had been exposed, and as Anonymous’s attacks continued, suspicions eased.
Barrett Brown, a former journalist who became closely associated with Anonymous, said Sabu’s betrayal would have a serious effect on Anonymous. “He was an admired Anon,” he said. “He’s been a leader. People came to him with information. God knows what else he told them.”
