Researchers at Israel’s Ben-Gurion University of the Negev have devised a way to turn any computer into an eavesdropping device by surreptitiously getting connected headphones or earphones to function like microphones.
In a paper titled "SPEAKE(a)R: Turn Speakers to Microphones for Fun and Profit," the researchers this week described malware they have developed for re-configuring a headphone jack from a line-out configuration to a line-in jack, thereby enabling connected headphones to work as microphones.
The exploit works with most off-the-shelf headphones and even when the computer doesn’t have a connected microphone or has a microphone that has been disabled, according to the researchers. more
