That’s impossible to prevent. If you have that level of hardware access and sophistication of modifying the device, you have already lost if you leave the computer alone.
The only way to prevent this in any way would be a light sensor on the other side of the case which you could use to check the Indicator when the laptop is closed. But if you can’t trust your hardware to that level, there are thousands of other attacks you can do.
- nebula8804 2y agoWell you have a point and I was thinking about it. Only thing I can think of is eliminating the LED in favor of software (which is what they have done in some products) or putting silicon in the LED to verify it. Ugh have we now reached the point where we have to put some crypto in everything including our LEDs?
- echoangle 2y agoI think that’s just a too advanced threat you want to handle. If you are facing such an opponent, you shouldn’t let your hardware out of your hands at any time. You can probably replace the battery by a smaller model and put a keylogger in the remaining space. There’s just no way to prevent hardware modification without using tamper evident seals on all openings, and even that probably isn’t 100% safe.
