If your smartphones, tablets, smart refrigerators, smart TVs and other smart devices are smart enough to make your life easier, their smart behavior could also be leveraged by hackers to steal data, invade your privacy or spy on you, if not secured properly.

One such experiment has recently been performed by a team of student hackers, demonstrating a new attack method to turn smart devices into spying tools that could track your every move, including inferring sexual activity.

Dubbed CovertBand, the attack has been developed by four researchers at the University of Washington’s Paul G. Allen School of Computer Science & Engineering, and is so powerful that it can record what a person is doing through a wall.

The CovertBand tracking system makes use of the built-in microphones and speakers—found in smartphones, laptops, tablets, smart assistant and other smart devices—as a receiver to pick up reflected sound waves, tracking the movements of anyone near the audio source.
