wiredmikey writes "Air Force officials have revealed more details about a malware infection that impacted systems used to manage a fleet of drones at the Creech Air Force Base in Nevada as reported last week. The 24th Air Force first detected the malware – which they characterized as a 'credential stealer' as opposed to a keylogger as originally reported — and notified Creech Air Force Base officials Sept. 15 that malware was found on portable hard drives approved for transferring information between systems. The infected computers were part of the ground control system that supports remotely-piloted aircraft (RPA) operations. The malware is not designed to transmit data or video or corrupt any files, programs or data, according to the Air Force. The ground system is separate from the flight control system used by RPA pilots to fly the aircrafts."
