Hacker of Sacramento Company HBGary Pleads Guilty

SACRAMENTO—United States Attorney Benjamin B. Wagner announced today the unsealing of the guilty plea of Hector Xavier Monsegur, aka “Sabu,” aka “Xavier DeLeon,” aka “Leon,” of New York City. Monsegur pleaded guilty to a 12-count information, which included the allegation that Monsegur conspired to carry out a hacking attack on HBGary, Inc. and HBGary Federal LLC. Monsegur entered his guilty plea in the Southern District of New York on August 15, 2011, but the plea was maintained under seal until today.

The broad case against six hackers, including Monsegur, is the product of an extensive investigation by the Southern District of New York, the New York Field Office of the FBI, and authorities in foreign countries. The attack on HBGary was carefully investigated by the FBI in Sacramento and the case was transferred to New York for Monsegur’s plea. Importantly, the Sacramento investigation greatly benefited from the assistance of HBGary itself.
