New acoustic attack steals data from keystrokes with 95% accuracy

This is a most excellent place for technology news and articles.
The room is important to the training of the model as well. So even if you know the make and model of the keyboard, the exact acoustic environment it is in will still require training data.
Also if you can install a keyboard of your choosing, you can just put the keylogger inside the keyboard. If you're actually getting your own peripherals installed on your target machine, training a model to acoustically compromise your target is the most difficult option available to you.
good point about the room.
as for an installed keylogger, there are organizations that will inspect for that and catch it. My point is this is a way to get an actually unmolested USB device into play.
But I hear you, this isn't likely an ideal option right now, but it is an option for maybe some niche case. And these are early days, put enough funding behind it and it might become more viable. Or not. Mostly I'm just offering the thought that there ARE use cases if someone puts even a moment's creative thought into trade craft and the problems it might solve like breaking the air gap, emplacement, avoiding detection, and data exfil. Each of those are problems to be solved at various levels of difficulty depending on the exact target.
