SkiifGeek writes "Early in March, Wintercore Labs published proof of a generic approach to defeating audio CAPTCHAs, using Google's as the case study for their demonstration. With claims of over 90% success rate and expectations that this can be significantly improved with the right mix of filtering algorithms, the in-house tool remains unreleased. But it shouldn't take long for other developers to create their own tools and start targeting not only Google, but other sites that use audio CAPTCHAs for the vision-impaired. It isn't the first time that major sites (significantly major webmail providers) have had their CAPTCHAs broken, but it is the first reporting of defeating an audio CAPTCHA using a generic software approach. News about the discovery is slowly starting to spread."
