Hacker-Turned-Informant Helps FBI with Arrests

One of the world's most-wanted cyber hackers secretly became an FBI informant last year and helped bring in five other suspected leaders of the loose-knit international Anonymous group who were charged with computer crimes. In a major blow to Anonymous, which has hacked the websites of government agencies and companies around the world, U.S. authorities said the hacker, Hector Xavier Monsegur, was arrested at his small apartment in a Manhattan housing complex last June.
