By the way, some (most?) videoconferencing software removes keyboard sounds from the audio, because it's particularly a distracting problem with laptops where the microphone is right next to the keys.

I'm pretty sure Zoom does this by default as part of its noise cancellation (it's potentially even easier since you can use keydown events to help identify, not just the audio stream).

So as long as basic default noise cancellation is on, that would at least prevent this over regular videoconferencing. And because of this, I'm having a hard time thinking of when else this would be a realistic threat, where the attacker wouldn't already have enough physical access to either install a regular keylogger or else a hidden camera.

Meetings between organizations, multi-office cafeterias, or coffee shops, perhaps.
