toomuchtoomuchspam writes "According to Websense, Microsoft's CAPTCHA has been busted again. CAPTCHA was surely a logical move for different service providers to fight against spammers. But seems like it is melting down. "Realizing the potential for massive abuse from spammers with anti-CAPTCHA capabilities, who could use the clean IP reputation to carry out various attacks over Email and Web space, Microsoft attempted to increase the complexity of their CAPTCHA system. The CAPTCHA system was revised in an attempt to both prevent automatic registrations from computer programs or automated bots, and preserve CAPTCHA's usability and reliability. As this attack shows, those efforts have failed." says Websense's security researcher Prasad. Could there be any better CAPTCHA, a better solution?"
