The FBI has used celebrity hacker “Sabu” to imprison his friends and prevent prevent more than 300 cyber attacks against the U.S. military, NASA and media companies in the past three years, CNN reports.
Hector Monsegur, who used the Sabu moniker online, helped crack down on hacking collectives Anonymous and LulzSec.
In exchange for his help, the government is seeking leniency. Monsegur previously faced up to 26 years in prison for identity theft and credit card fraud.
“Working sometimes literally around the clock, at the direction of law enforcement, Monsegur engaged his co-conspirators in online chats that were critical to confirming their identities and whereabouts,” prosecutors said. “During some of the online chats, at the direction of law enforcement, Monsegur convinced LulzSec members to provide him digital evidence of the hacking activities they claimed to have previously engaged in, such as logs regarding particular criminal hacks.”
