Ars Technica:

Siri, Alexa, and Google Assistant are vulnerable to attacks that use lasers to inject inaudible—and sometimes invisible—commands into the devices and surreptitiously cause them to unlock doors, visit websites, and locate, unlock, and start vehicles, researchers report in a research paper published on Monday. Dubbed Light Commands, the attack works against Facebook Portal and a variety of phones.

The article is fascinating, no doubt. But I had to laugh at the idea of shining a laser at Siri. She’s both immortal and invincible.

Kidding aside, the exploitable tech here is the MEMS mic. Interesting read, not a thing to worry about, at least for most mortals.
