Abstract
With recent developments in deep learning, the ubiquity of microphones and the rise in online services via personal devices, acoustic side channel attacks present a greater threat to keyboards than ever. This paper presents a practical implementation of a state-of-the-art deep learning model in order to classify laptop keystrokes, using a smartphone integrated microphone. When trained on keystrokes recorded by a nearby phone, the classifier achieved an accuracy of 95%, the highest accuracy seen without the use of a language model. When trained on keystrokes recorded using the video-conferencing software Zoom, an accuracy of 93% was achieved, a new best for the medium. Our results prove the practicality of these side channel attacks via off-the-shelf equipment and algorithms. We discuss a series of mitigation methods to protect users against these series of attacks.

- Macht eure Mikrofone aus, wenn ihr in einem Videocall nicht sprecht. Tippt keine Passwörter, wenn euer Mikro an ist. Und packt das Handy weg.

- This is a bit concerning especially for streamers. It may be a good idea to learn a habit of muting your mic when entering passwords in the future.
