One late-night visit by the FBI was all it took for the notorious hacker known as “Sabu” to switch sides and become a valued snitch. Hector Xavier Monsegur cooperated immediately in June, helping investigators close a net around five other leaders of the international hacking group Anonymous, according to court documents made public on Thursday. Monsegur sometimes stayed up all night, talking with co-conspirators to help the government build its case, Assistant U.S. Attorney James Pastore told a Manhattan federal court judge at a secret hearing days before Monsegur's August 15 guilty plea, the court papers showed. Monsegur, 28, was arrested at his small apartment in a Manhattan housing complex on June 7, U.S. authorities said on Tuesday in announcing charges against him and five others. The precise time, 10:15 p.m., was revealed in Thursday's court papers. “Since literally the day he was arrested, the defendant has been cooperating with the government proactively,” Pastore told Judge Loretta Preska.

Monsegur was freed on $50,000 bond the day after his arrest. He later pleaded guilty to each of the 12 computer crimes he was charged with in cases brought in four different states. The cases were later consolidated in New York. Federal prosecutors said Monsegur had confessed in court after signing a cooperation agreement with the government. Details of the deal and any reduction in prison time that he hopes to receive will not be known until the court makes the information public. Monsegur and the five others were senior members of Lulz Security (LulzSec), an offshoot of Anonymous that took credit for hacking attacks on government and private sector websites, U.S. authorities said on Tuesday. Targets included the CIA, Britain's Serious Organised Crime Agency, Japan's Sony Corp
Among those publicly charged this week was Jeremy Hammond, known as “Anarchaos,” who was arrested in Chicago on Monday on suspicion of hacking into Strategic Forecasting Inc, or “Stratfor,” a global intelligence and research firm, in December 2011. Federal prosecutors also brought U.S. cases against Donncha O'Cearrbhail, 19, and Darren Martyn, 25, of Ireland as well as Jake Davis, 19, and Ryan Ackroyd, 23, of Britain. Anonymous and its offshoots such as LulzSec and AntiSec were initially focused on fighting attempts at Internet regulation and blocking free illegal downloads, but have since taken on other targets including Scientology and the global banking system. Anonymous – and LulzSec in particular – became notorious in late 2010 when they launched what they called the “first cyber war” in retaliation for attempts to shut down the Wikileaks website. They attacked websites such as MasterCard.com that tried to block payments to Wikileaks after apparent pressure from the U.S. government following the release of thousands of diplomatic cables.

At the time of his arrest in June, Monsegur was unmarried and collecting a $400 unemployment check every month, a court document showed. He had been living in a small apartment on the sixth floor of a 14-story brick housing project on Manhattan's Lower East Side, overlooking a busy highway.
The document, which detailed his bail conditions and was made publicly available on Thursday, also showed that Monsegur was paid $6,000 a month at his last job, which he said he held until April 2010. Monsegur also stated that he had parental custody over his two nieces, aged 4 and 5. The case is U.S. v. Hector Monsegur, U.S. District Court, Southern District of New York, no. 11-666.
