Virus Infects Drone Network

A few weeks ago, at Creech Air Force base in Nevada, computer security experts came upon a virus in their network. The virus was recording every keystroke made by Air Force pilots who remotely operate Predator and Reaper drones that fly over war zones. And so far, they can't seem to wipe the virus from the system. Guy Raz talks to Noah Shachtman, contributing editor at Wired magazine, who first reported the story.
