This was certainly the last thing we expected to see today. [ShaunF] has created a Greasemonkey script to bypass the captcha on filehosting site Megaupload. It uses a neural network in JavaScript to do all of the OCR work. It will automobile submit and start downloading too. It’s quite a creative hack and is certainly assisted by the basic 3 character captcha the site employs. attempting to do the same thing with ReCAPTCHA has proven much a lot more difficult.

UPDATE: [John Resig] explained of how it works.
