Gmail, Yahoo and Hotmail’s CAPTCHA broken by spammers

[zatoicchi]

Breaking Gmail, Yahoo and Hotmail’s CAPTCHAs, has been an urban legend for over two years now, with do-it-yourself CAPTCHA breaking services, and proprietary underground tools assisting spammers, phishers and malware authors into registering hundreds of thousands of bogus accounts for spamming and fraudulent purposes.
This post intends to make this official, by covering an underground service offering thousands of already registered Gmail, Yahoo and Hotmail accounts for sale, with new ones registered every second clearly indicating the success rate of their CAPTCHA breaking capabilities at these services.

for spammers they did expect it, but it got out of control :wink: of course they can't resort to captchas like this, it makes life harder for legit users
