Security News > 2020 > June > ‘Lamphone’ Hack Uses Lightbulb Vibrations to Eavesdrop on Homes

The hack stems simply from a lightbulb hanging in the home.

In November, researchers discovered a new way to hack Alexa and Siri by pointing a laser light beam at the smart speakers' microphones to send them remote, inaudible commands.

Researchers tested the hack by placing multiple telescopes around 80 feet away from the lightbulb in a target office.

While researchers performed the hack from 80 feet away from the target bulb, they said that the range can be amplified with proper equipment - such as a bigger telescope or a different analog-to-digital converter.

Regardless, researchers stressed that leveraging electro-optical sensors in privacy-busting hacks will continue to undergo innovation in future attacks, making it even easier to eavesdrop in on sensitive conversations behind closed doors.
