A new acoustic side-channel attack that can reconstruct text typed on a laptop by analyzing nothing more than the sound of keystrokes.

    I don’t know how the existing solutions work, but the article mentions it being possible without training on the specific keyboard first and with 99% accuracy. And that would be frightening, especially combined with that sentence:

    The researchers describe three realistic attack scenarios, where an attacker could:

    • …
    • Recover keystroke sounds transmitted as background noise during online meetings

    How would I write shit about the idiots presenting in the meeting without them knowing?

      Luckily software like Teams has noise cancellation, so keyboard sounds generally get filtered out.

        The researchers further tested the attack against audio transmitted over Google Meet, Microsoft Teams, and Zoom. With noise suppression disabled, keystroke sounds carried through meeting audio were often sufficient to reconstruct typed text with high accuracy after a few hundred keystrokes, although results varied depending on the conferencing platform and laptop model. The paper notes that some users may still be exposed because advanced noise cancellation features are not always available or enabled.

        Not so fast…
