Defeating CAPTCHA

Comments (1) | Share

Microsoft MVP Casey Chesnut blogs about writing aiCaptcha, an application designed to comment spam blogs that use CAPTCHA images which are supposed to foil spam bots. It's a very interesting read for anyone who's into image processing and neural networks.

Casey comment spammed the blogs of 94 fellow MVP's in order to demonstrate the effectiveness of his AI tool and pissed off at least three people.
