Air Force says drone system was infected by common malware

Air Force officials said the virus infected ground systems that are separate from drone flight controls and did not affect operations.

An Air Force Space Command spokeswoman, Col. Kathleen Cook, says the infection was found on a small, portable hard drive used to transfer information between systems at Creech Air Force Base in Nevada.

The Air Force says the virus did not log computer keystrokes, but instead was designed to steal passwords from people who gamble or play games like Mafia Wars online.
