UNSEALED COURT DOCUMENTS show that Anonymous hacktivist Sabu cooperated with the authorities from the moment he was arrested.
Sabu, or Hector Xavier Monsegur, is the Anonymous/Lulzsec member that is widely credited with bringing down the latter hacking operation and helping the authorities bring in the rest of the team. According to the court papers he was a willing participant and a good worker.
The day after he was arrested he had already coughed information on other hackers and soon after was working hard to patch FBI computers with vulnerabilities that he knew could be exploited,
By August, two months after he had first met the authorities, he had patched as many as 150 vulnerabilities in computer systems.
According to the San Francisco Gate, part of the San Francisco Chronicle, he worked "round the clock" with the FBI, putting in full nights for his new paymasters.
The court papers, which we have not seen yet, show that Assistant US Attorney James Pastore gave Sabu a glowing reference in front of US District Judge Loretta Preska at a hearing in early August.
"Since literally the day he was arrested, the defendant has been cooperating with the government proactively," said Pastore.
"The defendant has literally worked around the clock with federal agents. He has been staying up sometimes all night engaging in conversations with co- conspirators that are helping the government to build cases against those co-conspirators." µ
