Vibrations in Lightbulbs allowing Individuals to Eavesdrop

A new hack allowed researchers to discern sound — including “Let it Be” by the Beatles, and audio from a Donald Trump speech — from lightbulb vibrations.

Researchers have discovered a novel way to spy on conversations that are happening in houses from almost a hundred feet away. The hack stems simply from a lightbulb hanging in the home.

The hack, dubbed “lamphone,” is performed by analyzing the tiny vibrations of a hanging lightbulb, which are caused by nearby sounds. All an attacker would need is a laptop, as well as a telescope and an electro-optical sensor (altogether costing less than $1,000). They would also need to set up near the window of a room that contains the hanging lightbulb.
