A former contractor for Siemens planted logic bombs in projects he designed that caused them to periodically malfunction. Then wait for a call to come fix things.

David A. Tinley, 62, pleaded guilty to a charge of intentional damage to a protected computer.

According to the U.S. District Court for the Western District of Pennsylvania, the logic bombs Tinley surreptitiously planted into his projects caused them to malfunction after a preset amount of time. Because Siemens managers were unaware of the logic bombs and didn't know the cause of the malfunctions, they would call Tinley and ask him to fix the misbehaving projects.

Tinley was sentenced to six months in prison and fined $7,500.
