It seems very important speaking about CAPTCHA recognition. To me, this is not a "big" news; it's from many years that scientific community developed lots of "vision-recognition" algorithms able to exploit the most moderns CAPTCHA engines. Anyway tonight I wanna point out this interesting work from "The Russian hackers" team.
You can find the Project here.
Actually they reach the 35% of accuracy, that doesn't sound like a big deal but if you consider that an attacker performs 100,000 CAPTCHA attacks per day, the 35% becomes a great threshold.
PS: in order to see the project you need at least MATLAB 2007.
