Yahoo CAPTCHA Hacked

Thursday, 31 January 2008 11:21 by Selecters

A team of Russian hackers has found a way to decipher a Yahoo CAPTCHA, thought to be one of the most difficult, with 35% accuracy. The Russian group's notice, posted by one "John Wane," is dated January 16. This site hosts a rapidshare link to what looks to be demonstration software for Windows, and quotes the Russian researchers: "It's not necessary to achieve high degree of accuracy when designing automated recognition software. The accuracy of 15% is enough when attacker is able to run 100,000 tries per day, taking into the consideration the price of not automated recognition " one cent per one CAPTCHA.

I guess new version of Captcha is not that easy to hack ! Sometimes it is hard for humans to read with,I wonder how automated tools will read that. Try your luck with that Guys ! & Lets keep posted . Is there also anyway to hack Sound version of Captcha ... ? But I appreciate real nice work with Yahoo !

With enough resources on time and knowledge I don't see it as impossible. If you want to fund the project, I'm all ears Wink
