Lamphone - Real-Time Passive Reconstruction of Speech Using Light Emitted from Lamps

Explore a novel side-channel attack called "Lamphone" in this Black Hat conference talk. Discover how this real-time, external, and passive eavesdropping technique analyzes a hanging light bulb's frequency response to sound using a remote electro-optical sensor. Learn about the limitations of previous side-channel attacks and how Lamphone overcomes these constraints. Gain insights into the potential privacy threats posed by this innovative method of reconstructing speech from light emissions. Presented by Ben Nassi, this 37-minute talk delves into the technical aspects and implications of this cutting-edge eavesdropping technique.
