A team of researchers from various universities in the USA has created a new program that kills captcha protection. The program called decaptcha breaks captcha protected sites via the audio interface, and has a success rate of between 41% to 89%. That means that captcha protection on websites is essentially killed as bots can easily try hundreds of attempts every minute.
The Decaptcha program is a learning algorithm, meaning that you need to train it to recognize the various speech sounds from different captcha methods, but once its trained it will be able to auto-fill captcha code on sites using the same methods.

This is not good news for us, as this increases the ability for hackers to get into members areas protected by strongbox and other captcha enhanced security tools. I would really love to hear from them, hopefully someone will be by to explain how this will affect things!
