Researchers Hack Siri Alexa And Google Home By Shining Lasers

Dan Goodin writing for Ars Technica:

The attack exploits a vulnerability in microphones that use micro-electro-mechanical systems, or MEMS. The microscopic MEMS components of these microphones unintentionally respond to light as if it were sound. While the researchers tested only Siri, Alexa, Google Assistant, Facebook Portal, and a small number of tablets and phones, the researchers believe all devices that use MEMS microphones are susceptible to Light Commands attacks.
