As posted to Hacker Webzine: It has been suggested before that it would be a matter of time, but now it seems official: The Yahoo! CAPTCHA is no-more. A team of Russian hackers have found a way to read the CAPTCHA with 35% accuracy. Let there be no mistake: the CAPTCHA that Yahoo! deploys is believed one of the most difficult CAPTCHA’s to crack. It utilizes bended alpha numeric characters and other features you might expect from a strong CAPTCHA, and still it’s easy to solve by humans.
For more information, as well as a download of the client/server Yahoo CAPTCHA recognition engine check out the blog run by the Russian researchers.
