Turning off camera LEDs and recording video is an old hack and old news. This is for a specific firmware and computer model and attack surface via USB to update the webcam's firmware, so I am assuming that makes it news?

EDIT: I keep a piece of black electric tape over any of my notebook's webcams.

This.

Some of the linux webcam drivers drivers have had the option to specify the behavior of the LED via a parameter since way back, including turning it completely off.

I remember this was the case ~20 years ago.

One example (look for the led-option) https://www.kernel.org/doc/html/v5.1/media/v4l-drivers/phili...

This is straight from the documentation:

"But with: `leds=0,0`the LED never goes on, making it suitable for silent surveillance"

Many assume that led indicators are tied to hardware rather than firmware. And this just proves that it is still not always the case.
