Think viruses are dangerous? Watch out for JitterBugs

By | August 7, 2006

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.Read Full Story
