The Columbus Dispatch reports that US District Judge Peter C. Economus said Miller was a member of the KCUF hacking clan in 2008 when the group organized an attack on the PlayStation Network, potentially compromising user data.
The FBI contacted Miller while investigating another hack in 2011 that resulted in an extended PSN outage. After obtaining a search warrant, the FBI entered Miller's home to find that his computers were smashed and his hard drives were missing. Lacking evidence to bring up Miller and another suspect on hacking charges, the FBI instead charged Miller with obstructing the investigation.
While Miller faced up to 20 years in prison and a $250,000 fine, he was sentenced to three years of probation and a year of house arrest for obstruction of justice. The judge additionally ordered Miller to obtain a high-school equivalence certificate, as part of his sentencing.
