As a hacker, Hector Xavier Monsegur Monsegur led an Anonymous splinter group called Lulz Security, or LulzSec. They hacked the computer systems of Fox television, Nintendo, PayPal and other businesses and stole private information. After his arrest, the FBI estimated that he helped detect at least 300 separate hacks, preventing millions of dollars in losses. The U.S. District Judge Loretta Preska, who decided Tuesday to stop Xavier’s detention appreciated his”extraordinary cooperation”. If it was inflicted, the primary sentence ,under United States Sentencing Guidelines, should be about 21 to 26 years. Monsegur “provided crucial, detailed information regarding computer intrusions committed by [hacking groups associated with Anonymous]“, the memo presented now by the prosecutors said and this helped him to be free.
