FIELD: information technology.
SUBSTANCE: method of breaking the keyboard password to a computer inside a room with limited access involves using listening devices from the outside to pick up sounds arising when entering the password on the keyboard during user verification, and decrypting said sounds using a sound-character alphabet, where the software of the computer is deliberately crashed and the password is intercepted when rebooting the software during user verification.
EFFECT: fast password breaking by cutting the time for waiting for password entering.
