How Hackers Listened Their Way Around Google's Recaptcha

Posted by timothy on from the listen-to-what-the-flower-children-scream dept.

An anonymous reader writes with this story at Ars Technica: "Three self-taught hackers from the DC949 hacker collective managed to use a combination of techniques to beat ReCaptcha with 99.1% accuracy (better than most humans!)" In short, the hackers skipped the visual part of the Recaptcha system entirely, focusing on the audio alternative, which gave them a few convenient angles of attack. Google responded with changes to the system, but that doesn't minimize their accomplishment.

    That's it! Make all users do a SERIES of incredibly hard recaptchas. Those who get too many correct are machines! Brilliant!

    If they can solve captchas at 99% accuracy, I hope they develop a browser toolbar or plugin I can use.
