At the large public housing project in New York City where he lived, outsiders knew him as a quiet family man. But federal prosecutors say Hector Xavier Monsegur was an internet saboteur known as Sabu.

During the Arab spring, prosecutors say he hacked into government websites in Tunisia, Yemen and Algeria. He helped coordinate attacks on credit card companies after they refused to accept donations to Wikileaks. Then, they said, he added another layer to the subterfuge by informing on his accomplices after he was caught by the FBI last spring.

Did the FBI know in advance of the Stratfor hack, but let it happen in order to gather evidence?

Soon after the news broke yesterday (March 6) about the arrest and cooperation of turncoat Anonymous and Lulzsec hacker Hector Xavier Monsegur, known online as "Sabu," the Justice Department released chatroom transcripts that imply the FBI knew in advance of the devastating attack in December upon the Austin, Texas geopolitical analysis firm Strategic Forecasting, Inc.

All those computer users whose Internet access was about to be cut off by the FBI can breathe a bit easier.

Late yesterday (March 5), federal Judge Denise Cote granted the federal government another 120 days to keep running several Domain Name System servers that were keeping hundreds of thousands, and possibly millions, of infected computers online.

According to the FBI, you're looking at Sabu, the head of LulzSec, and the de facto King of Anonymous—easily the most notorious and influential hacker alive today. One thing: he just turned in his people to the police.

Businesses are not taking Anonymous and hacktivism seriously enough, according to an FBI special agent.
