This seems like an entirely academic, theoretical technique with literally zero real world risk, and without any path forward to ever turn it into a practical attack.

I think the last paragraph OP posted really highlights the niche risk it poses. Nobody is going to use it against you, but a state actor could use it against a specific target like a politician or military to develop a more accurate assessment of information they already have been collecting.

The GrapheneOS part of things feels a little baity. I switched from Brave to LibreWolf a year ago over similar privacy concerns, but ultimately all my biggest risks come from breaches that happened before I was even using Brave.

  I read the whole article and I think even that is a ludicrous stretch. In order to get a vague image of your hand it requires either several minutes of projecting a precise black and white bright checkered pattern on the screen, or over an hour of subtly embedding varied brightness in a video. The checkered pattern represents a best/worst case scenario for this kind of attack, and even that is completely impractical for anything in the real world. This is literally zero risk for everybody. Forever.

  Indeed, it does.

  I am not affiliated with GrapheneOS in any way. I have mentioned GrapheneOS because it is the only Android-based, open source, privacy and security-focused mobile operating system I’m aware of which offers the functionality to disable sensors for each app while also happening to be recommended by PrivacyGuides as the best choice when it comes to privacy and security. If you happen to know of better alternatives, please provide your reasoning and I will gladly list them too.
