FOX News: 'Lamphone' technique allows spies to target victims using lightbulbs for real-time eavesdropping
Researchers turn lightbulbs into microphones
Forget wiretapping -- researchers have developed a new way for spies to eavesdrop on targets using lightbulbs.
The technique is called “lamphone” and was developed by researchers at Israeli's Ben-Gurion University of the Negev and the Weizmann Institute of Science. It uses a special sensor to analyze a hanging lightbulb’s frequency response to sound through fluctuations in air pressure that cause vibrations.
Using lamphone, attackers can recover speech and sounds from an individual in another location. The tactic, first reported by Wired, is said to only require a laptop, a telescope and an electro-optical sensor to carry out.
