Optical Sound Recovery from Lightweight Reflective Objects

Explore an innovative optical side-channel attack called "the little seal bug" in this 38-minute Black Hat conference talk. Discover how eavesdroppers can passively recover speech from lightweight reflective objects commonly found in home offices by exploiting air pressure fluctuations on shiny surfaces. Learn about the potential security implications of this technique, which uses equipment not typically associated with spying, especially relevant in the context of increased remote work during the COVID-19 pandemic. Presented by Ben Nassi, Raz Swissa, and Boris Zadov, this talk delves into the intricacies of optical sound recovery and its potential impact on privacy and security in modern work environments.
