In the world of information security, there are many cutting-edge attacks. Like the one out of Israel, researchers from Ben-Gurion University and the Weizmann Institute created a technique for long-distance eavesdropping they call lamphone.
The lamphone attack allows anyone with a laptop, telescope, and a $400 electro-optical sensor, to listen in on any sounds in a room that’s hundreds of feet away in real-time by merely observing the minuscule vibrations those sounds create on the glass surface of a light bulb inside.
