Real-Time Passive Sound Recovery from Light Bulb Vibrations
Spies Can Listen to Your Conversations by Watching a Light Bulb in the Room
You might not believe it, but it's possible to spy on secret conversations happening in a room from a nearby remote location just by observing a light bulb hanging in there—visible from a window—and measuring the amount of light it emits.
A team of cybersecurity researchers has developed and demonstrated a novel side-channel attacking technique that can be applied by eavesdroppers to recover full sound from a victim's room that contains an overhead hanging bulb.
The findings were published in a new paper by a team of academics—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, which will also be presented at the Black Hat USA 2020 conference later this August.
The technique for long-distance eavesdropping, called "Lamphone," works by capturing minuscule sound waves optically through an electro-optical sensor directed at the bulb and using it to recover speech and recognize music.

Recent studies have suggested various side-channel attacks for eavesdropping sound by analyzing the side effects of sound waves on nearby objects (e.g., a bag of chips and window) and devices (e.g., motion sensors). These methods pose a great threat to privacy…
