Investigated by the FBI and prosecuted by the Computer Hacking and Intellectual Property (CHIP) Unit of the United States Attorney's Office, the case against the perpetrator of a Trojan virus attack against Microsoft WebTV subscribers, David Jeansonne, was sentenced on Monday to six months in prison and another six months of home detention.

44 year-old David Jeansonne, from Louisiana, pleaded guilty to intentionally damaging computers and causing a public safety threat.

The $27,200 is payable to Microsoft. Microsoft's WebTV has since been renamed MSN TV. 

Jeansonne sent the e-mails to at least 20 subscribers. Half of them activated the virus, unknowingly placing 911 calls that resulted in the wasteful and unnecessary arrival of officers at their homes.
