I didnt find an article about actual hacks carried out with that technique, but here’s a HN discussion [1] from this month about a paper on the topic.

From that discussion it sounds like you need to train on data captured from the actual target. Same physical keyboard in the same physical space with the same typer.

Pretty wild despite those specific conditions. Very interested to know if people have actually been attacked in the wild with this and if the attackers were able to generalize it down to just make and model of a keyboard, or if they could gather enough data from a stream.
