ReCAPTCHA.net Now Vulnerable to Algorithmic Attack

Posted by timothy on from the bless-you! dept.

n3ond4x writes "reCAPTCHA.net algorithms have been developed to solve the current CAPTCHA at an efficacy of 30%. The algorithms were disclosed at DEFCON 18 over the weekend and have since been made available online. Also available is a video demonstration of random reCAPTCHA.net CAPTCHAs being subjected to the algorithms." There's probably an excellent Firefox plugin to render this page's color scheme more bearable. Note: the PowerPoint presentation linked opens fine in OpenOffice, and the video speaks for itself.

    The quote is: "My eyes! The goggles do nothing!".
    There is no "they", nor is there any bad pronunciation. Indeed, it is correctly articulated and enunciated, with an accent.

    Hey drinkypoo,

    Nothing to do with your post, but I have five modpoints. I am tired of you vomiting ten comments in a thread before I can even read the summary. Be prepared to lose a bunch of karma, you stupid pencilneck nerd.
