93% - 95% accuracy and it wasn't even a good quality recording > 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. https://arxiv.org/abs/2308.01074

> Passwords Which reminds me, to strengthen your point, it doesn't have 100% keystroke recognition, but there are works[1] on keylogging via audio, and 93% via Zoom-quality audio streams is concerning enough for me. [1] https://arxiv.org/abs/2308.01074

No details about what specific study they are referring to. These attacks are possible for several years now. 2016 - "Don't Skype & Type! Acoustic Eavesdropping in Voice-Over-IP" - https://arxiv.org/abs/1609.09359 2020 - "Behavioral Acoustic Emanations: Attack and Verification of PIN Entry Using Keypress Sounds" - https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7309150/ Maybe they mean this one... 2023 - "A Practical Deep Learning-Based Acoustic Side Channel Attack on Keyboards" - https://arxiv.org/abs/2308.01074

Keystroke timing attacks have been known for quite a while - heres a highly cited paper from over 20 years ago: https://www.usenix.org/conference/10th-usenix-security-sympo... Recently there has been some work on using audio of keypresses to determine what's been typed: https://arxiv.org/pdf/2308.01074.pdf . The statistical analysis described earlier works better when you have samples of a person's typing to try and learn whats been sent, but the acoustic work has raised some concerns that ML techniques can be used on just packet timings to determine what's been typed without a pre-determined…

Another reason for using a password manager is the fact of keyboard-related attacks getting more widespread. Case in point: A Practical Deep Learning-Based Acoustic Side Channel Attack on Keyboards (https://arxiv.org/pdf/2308.01074.pdf)
