Multitasking while on a work-related Skype call may be good for productivity, but perhaps not so much for privacy. Typing while using Skype or over other Voice over Internet Protocol (VoIP) services presents an opportunity for an attacker to record the conversation, separate out the emanations from the typing, and use previous work in this field to analyze the sounds and accurately guess what’s being typed.
The research was presented in a paper published this week called “Don’t Skype & Type! Acoustic Eavesdropping in Voice-Over-IP,” written by Alberto Compagno of the University of Rome, Mauro Conti and Daniele Lain of the University of Padua, and Gene Tsudik of the University of California Irvine.
