Please change the title to the actual paper: "Light Commands: Laser-Based Audio Injection Attacks on Voice-Controllable Systems"

The paper is about sending voice commands using lasers, not sound. There's also no mention of "root access", the paper is just about replaying audio-converted-to-light rather than having any kind of interactive "root" shell prompt. The only feedback to know whether the exploit succeeded would be sending commands (e.g. unlock a door), which the victim might notice.

Agreed, this title is amazingly inaccurate.

Agreed, it has nothing new beside the YouTube video demoed a few months ago by exploiting MEMS microphone on voice assistants. The pictures in the paper is hilarious, an oscilloscope showing two Sin waves from the internal calibration source, seriously?
