Security researchers at Israels Ben Gurion University have created a proof-of-concept exploit that lets them turn headphones into microphones to secretly record conversations. Malware that turn Headphone as Microphone converted the vibrations in air into electromagnetic signals to capture audio from across a room. Researchers managed to switch the output sound channel as an input one, where intelligible audio can be acquired through earphones and can then be transmitted distances up to several meters away. The attack works on practically any desktop computer, whether it runs Windows or MacOS.”]
