Everybody suggest users to cover webcams since they can be activate remotely and check our keyboard for passwords or spy our personal life.
But how about microphone? It is less dangerous? Looks it isn't. Microphone in combination with keyboard can reveal your password. How? Every keyboard button has specfic sound. If you mic is close enough and can detect such difference, typing password somebody from other side with proper tools can convert keyboard sound into letters.
What do you think about this way of attack? How any perifer device is safe for us?
