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.

    ...especially if they solve them in less time than the duration of the audio. (Only half kidding: They solved millions of eight second long captchas in a second and a half each and Recaptcha didn't even blink.)
