Boffins convert typing sounds into text with 95% accuracy (www.theregister.com)

Researchers in the UK claim to have translated the sound of laptop keystrokes into their corresponding letters with 95 percent accuracy in some cases.

That 95 percent figure was achieved with nothing but a nearby iPhone. Remote methods are just as dangerous: over Zoom, the accuracy of recorded keystrokes only dropped to 93 percent, while Skype calls were still 91.7 percent accurate.

In other words, this is a side channel attack with considerable accuracy, minimal technical requirements, and a ubiquitous data exfiltration point: Microphones, which are everywhere from our laptops, to our wrists, to the very rooms we work in.

Can we normalise good but quiet keyboards. Like, I like the tactile feel of using a mechanical, but I hate the sound. Quieter mechanical keyboards aren't a thing but they should be. Now as a security measure if nothing else.

Also Dvorak keyboards I guess

There are tons of quiet mechanical keyboards. I'm using a low profile optical switch that's quieter than my mouse clicks

Are those optical switches expensive though?
