Glowworm: An Attack Technique that Recovers Sound via LED

A team of researchers at Ben-Gurion University came up with a new attack vector called Glowworm that can enable eavesdropping on Zoom and other virtual meetings by analyzing optical emission from a LED of a device. Glowworm is a similar attack as Lamphone that allowed the recovery of sound from a victim’s room having a light bulb. As complicated as the Glowworm attack sounds, researchers have suggested an easy and unconventional solution for users.
