The folks at dc949 have released an interesting tool called Stiltwalker this week.
From dc949:
Stiltwalker is a proof of concept tool that defeats Google’s reCAPTCHA with an insanely high accuracy (99%). We have released all of our research, code, tools and examples used in the reCAPTCHA domination. You can get the slides here and the video is at the bottom of the page.
We accomplished this with a combination of Machine Learning, hashing methods, keyspace reduction tactics, and taking advantage of an overall limited number of captchas. Specifically, Stiltwalker goes head to head against reCAPTCHA’S audio captcha system and defeats all but a sliver of it’s challenges.
For all questions, comments, and fuckyous, please email the team at stiltwalker@dc949.org
For more on this tool, read on.
