Abstract
CAPTCHA tests aim at preventing attackers from performing automatic website registration. In this paper we show that our prototype Decaptcha is able to successfully break 75% of eBay audio captchas. We compare its performance with the state of the art, readily available speech recognition system Sphinx and discuss the implications for eBay security.
