So they generated training data from one laptop and microphone then generated test data with the exact same laptop and microphone in the same setup, possibly one person pressing the keys too. For the Zoom model they trained a new model with data gathered from Zoom. They call it a practical side channel attack but they didnt do anything to see if this approach could generalize at all

I believe that is the generalisable version of the attack. You're not looking to learn the sound of arbitrary keyboards with this attack, rather you're looking to learn the sound of specific targets.

For example, a Twitch streamer enters responses into their stream-chat with a live mic. Later, the streamer enters their Twitch password. Someone employing this technique could reasonably be able to learn the audio from the first scenario, and apply the findings in the second scenario.

Finally, a real security weakness to cite when making fun of people for their mechanical keyboard. Time to start recording the audio of Zoom calls with some particularly loud typers...

I'll just have to add significantly more background clickity clacks as obfuscation.

My thought was to run psyops all the time.

"Just need to type in my password." He says a little too loudly to nobody. Then just type in the honeypot password and login with the real one that you entered with a virtual keyboard a few minutes ago.

Meanwhile you've got a prerecorded keyboard going concurrently that decodes to "I know what you're trying to do. Clever but not clever enough."

And I guess you might as well have a special keyboard that you only use for typing in passwords while you're at it.
