How Hackers Can Use Pop Songs To 'Watch' You (fastcompany.com) 33

An anonymous reader quotes a report from Fast Company: Forget your classic listening device: Researchers at the University of Washington have demonstrated that phones, smart TVs, Amazon Echo-like assistants, and other devices equipped with speakers and microphones could be used by hackers as clandestine sonar "bugs" capable of tracking your location in a room. Their system, called CovertBand, emits high-pitched sonar signals hidden within popular songs -- their examples include songs by Michael Jackson and Justin Timberlake -- then records them with the machine's microphone to detect people's activities. Jumping, walking, and "supine pelvic tilts" all produce distinguishable patterns, they say in a paper. (Of course, someone who hacked the microphone on a smart TV or computer could likely listen to its users, as well.)
