JitterBugs could turn your keyboard against you


Researchers from the University of Pennsylvania School of Engineering and Applied Science warn against an entirely new threat to computer security: peripheral devices such as keyboards, mice or microphones which could be physically bugged in an attempt to steal data. Penn graduate student Gaurav Shah has identified a class of devices that could covertly transmit data across an existing network connection without the user's knowledge.

They are called JitterBugs, named by Shah's advisor, Penn Associate Professor Matthew Blaze, for both the way they transmit stolen data in "jittery" chunks by adding nearly imperceptible processing delays after a keystroke and for the "jitters" such a bug could inspire in anyone with secure data to safeguard.
