Apple Exclaves and the Secure Design of the MacBook Neo’s On-Screen Camera Indicator

“What that means in practice is that even a kernel-level exploit would not be able to turn on the camera without the light appearing on screen.”

@daringfireball The one concern I'll still have about an onscreen indicator vs an indicator inside a notch or inside a bezel, is that you can manipulate the pixels *around* that area (background or menu bar background). So, sure, you might not be able to (easily) prevent that green indicator from being shown, but presumably cleverly crafted apps (especially ones running in full screen mode) or socially engineered attempts to convince people to install "pretty" looking backgrounds can change the background around that area to make the indicator very hard to *see*?

@leoncowle I propose you try to mock up such a thing, that wouldn't look really weird, ugly, and suspicious.

@ahltorp @leoncowle Do you think people wouldn’t notice that?

@gruber @leoncowle I do think most people would not be suspicious, yes.

It is also what I had time to do in a couple of hours. This pattern is secure against them having a quite large black border around the dot, which I got the impression they don’t, so it’s probably unnecessarily conservative.

I don’t have access to the hardware and thus the exact behaviour of the dot, so that limits me somewhat.
