Meet Francis Janosko, a former inmate at the Plymouth County Correctional Facility in Massachusetts who was arrested by the last week in North Carolina for allegedly accessing systems on the prison's computer network without authorization and , including the Social Security numbers and other personal information of about 1,100 current and former prison workers.

Janosko, 42, was charged with one count of intentional damage to a protected computer and one count of aggravated . If convicted on both charges, he faces up to 12 years in prison and a fine of up to US$250,000.

An announcement about Janosko's arrest that was released last Thursday by the U.S. attorney's office in Boston didn't say why Janosko was serving time before nor when he was released from the correctional facility. A spokeswoman for U.S. Attorney Michael Sullivan declined to provide those details and also wouldn't disclose how or when law enforcement authorities learned of Janosko's alleged intrusions into the prison's IT systems.

According to indictment papers that were unsealed last week, Janosko was allowed to use a thin-client device for accessing a server containing legal research while he was an inmate at the Plymouth County correctional center.

The system was configured to prevent inmates from accessing other applications on the server as well as the Internet, e-mail and other computers on the prison's network. But the server was connected to the Internet via the same physical network as the other prison systems in order to download Windows as needed.
