A former prisoner of the Plymouth County Correctional Facility in Massachusetts has been sent back to prison for 18 months for hacking into the correctional facility's computer network and accessing personal data on over 1,100 of its employees.

"Francis G. Janosko, 44, received the sentence earlier this week in federal court in Boston after pleading guilty to the hacking offenses in September," writes The Register's Dan Goodin.

"In addition to the employee database, Janosko was also able to access the internet to download videos and photographs of prison employees, inmates and aerial shots of the prison, according to court papers," Goodin writes. "The hacking took place between October 2006 and February 2007."
