The US military's large fleet of Predator and Reaper drones stationed in Afghanistan has been hit with a computer virus which logs every keystroke of the pilots flying their missions. The virus was first detected at Creech Air Force Base in Nevada (where the vast majority of military drones are controlled from) about two weeks ago, and while the military has been unable to remove it from its computers, no missions have been stalled because of the infection.

A source close to the situation told Wired that the virus seems to be benign, as no confidential information has leaked in spite of the fact that each time the virus is removed, it returns. It is also unclear whether the virus is just an unintentional, accidentally acquired piece of malware or not, and they do not know how far the malware has spread, though machines with both classified and unclassified information have been affected. The US military has, so far, not commented officially on the situation.
