Скачать или смотреть Keytap3: acoustic eavesdropping test for keyboards

A web page that allows you to perform a test on your mechanical keyboard to see if it is vulnerable to acoustic eavesdropping attacks:

The phone captures the sounds that the keyboard makes while typing on it and tries to recover the text by analyzing the recorded audio. If it succeeds to recover the text, it means that the keyboard can be easily spied on through a nearby microphone.

"this is a short demonstration of using this tool to test a mechanical keyboard thanks for watching"

Keyboard: QPAD MK-75 Cherry MX Switches
Phone: iPhone 13 Mini

Edit: A user requested that I made another example with plugged keyboard and compare the recovered and actually typed text. Here it is:    • Keytap3: another example
