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.

    I think I might have achieved security through obscurity. My custom keyboard is a unique shape and almost all the keys are one unit. Not only is it different enough from a traditional keyboard that the neural network probably won’t understand it, the function layers I use obscure whether I’m typing a letter at all.

        What keyboard is it, corne? I have to admit that your keycaps are incredibly cursed, how you have mixed caps from different layers

          It’s a chocofi.

          CTGAP on the base layer, and 6 layers on top of it, using a heavily modified version of Miryoku.

          Most of the keycaps are correct, just for different layers. It helps prevent key peeking, plus I like the cursed aesthetic.

            that’s a surprisingly cheap keyboard. I ended up ordering a zsa voyager a couple days ago because I wanted keys, but I couldn’t find any prebuilt split keyboards that had a base configuration below like $350. I might end up going with cursed keys on mine, it looks pretty cool
