Ditto. Or even an old-school LED that indicates data transmission like the HDD LED in old computer cases. Make it in hardware so that if any data is sent through the wire, it lights up.
Old? I'll admit I haven't changed my case in a couple years, but mine currently has one, and I can't remember the last time I've used a desktop computer that didn't have one.
I think you are confusing this with data tx/rx lights for exfil[0]? I've never heard of a tempest attack (that is, revealing the data written via a side channel) on a hard drive light.
Yeah it's type II in the Loughry schema. Still unfortunate if you're operating a high security air gapped network, but not squirting out secrets without being compromised first.
It seems almost quaint to worry about this when so much software has web spyware baked into it -- but maybe we need a virtual spyware led that lights up every time something talks to Facebook/Google/etc tracking. The light would be blinking non-stop for many people.
Having it in the status bar would defeat the purpose as ill behaving actors could possibly circumvent this, having it in the hardware as a led would make this if not impossible most likely infeasible. I’ve only heard one instance where someone were able to go around the led and if I recall correctly that was on the old PowerBook and required physical access to flash the firmware on the camera hardware module with custom malicious firmware.
I never understood how an expensive device like a camera was added to literally every laptop in existence without any option to remove (save for a few). I can only think manufacturers were pressured.
Supply chain/production complexity. It's more expensive for them to make the option customizable than it is to ship it for everyone. If there was an appreciable market for consumer-level camera-less machines the math to justify it might look different but there isn't. The vast VAST majority of the demand for hardware without cameras comes from the NatSec type people, and they're all doing bulk orders so they get more leverage to have niche production runs done for them. And even then they don't always get devices without the cameras. They end up having to do awkward things like physically disabling the hardware after the fact or locking out the functionality with custom firmware.
