Threat Actors Can Eavesdrop Using a Light Bulb’s Vibrations: Research

A group of cybersecurity researchers discovered a novel side-channel attacking technique that allows eavesdroppers to spy on conversations happening in a room from a nearby location by watching a light bulb hanging in that room. In a research report , security researchers Ben Nassi, Yaron Pirutin, Adi Shamir, Yuval Elovici, and Boris Zadov from the Israeli’s Ben-Gurion University of the Negev and the Weizmann Institute of Science stated that a technique called “Lamphone Attack” works by capturing microscopic sound waves via an electro-optical sensor focused at the bulb and using it to recover speech and recognize music. “Any sound in the room can be recovered from the room with no requirement to hack anything and no device in the room.
