Researchers at Georgia Tech have demonstrated how they were able to spy on what was typed on a regular desktop computers keyboard via the accelerometers of a smartphone placed nearby. It sounds like the stuff of James Bond, but the researchers paint a scenario where a criminal could plant a smartphone on the desk close to the keyboard and use specialist software to analyse vibrations and snoop on what is being typed. It’s a quite beautiful twist on how bad guys could use microphones to hear keystrokes and spy on your passwords.”]
