An unrepentant self-described “hacktivist” was sentenced Friday to 10 years in prison for illegally accessing computer systems of law enforcement agencies and government contractors.

Before hearing his sentence, Jeremy Hammond, 28, told Southern District Judge Loretta Preska (See Profile) that his goal was to expose injustices by the private intelligence industry when he joined forces with Anonymous, the loosely organized worldwide hacking group that has stolen confidential information, defaced websites and temporarily put some victims out of business.
