This is cool research, but I hope people aren't viewing this as a real-world worry. By the time someone is breaking into my house to set up hundreds of dollars worth of laser equipment, I probably have bigger problems.
If you'd actually read the paper, you can see that they were able to inject commands through double pane glass from 75 meters away.
I know, but I have a fence around my house. Once someone is setting up equipment around my house, why not just smash a window and steal my stuff directly?
Huh? I mean we have seen the WiFi person detection hacks through walls that need a lot of calibration, careful setup and so on, but this was pretty straightforward. Modulate your sound signal onto the laser current and it reproduced more or less directly.
They triggered the device from across the street.
For this attack nobody needs to break into your home. It can be executed from a distance (100m) and through "clear glass windows."
The hardware can be much cheaper. Furthermore, stealing very expensive cars would pay off the cost very quickly.
and, the attack may be "open the front door / garage door" ...
