Stealing passwords with a microphone

Anyone can launch a keystoke logger to steal computer info, but the truly talented can do it via a mic.

Researchers at UC Berkeley found that after audio taping a person typing for 10 minutes, they could figure out 90% of the words typed and guess the person's password in fewer than 20 attempts.

"Primarily this is a message to the security community saying we need to change our thinking on authentication," said Doug Tygar, a professor of computer science and information management at UC Berkeley and the principal investigator of the study. "This is not very exotic attack in that the equipment used is dirt cheap and the software is readily available."
