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.

    Quite scary considering the accuracy and how many open mics everyone is surrounded by without even realizing it. Not to mention if any content creator types their password while live streaming or recording they could get their accounts stolen.

      One more reason to switch to a password manager, even though they could still find out the master password…

        Probably still have some safety if you’re using two-factor, or have a master key in addition to a password (e.g. 1Password).

          That’s the whole point though. The louder your keypresses the better.

      This has been a known attack vector for years, and I wonder how no livestreamer has been (publicly) attacked in this way.

      I guess in large part this can be attributed to 2FA, passwords just aren’t worth much by themselves anymore (well I guess if someone is quick enough they can snipe the OTP as well, but streamers are rarely entering their 2FA while streaming since they’re on a trusted device).

      In fact the biggest attack vector I’d worry about is the infamous SMS 2FA, which is actually 1FA for password resets, which is actually 0FA “yes dear phone operator I am indeed Mister Beast please move my phone number to this new SIM”.
