After some time of browsing the web we found a set of new CAPTCHAs which must take a place in a Weakness list. Some of them are small and local, but it also contain a world wide famouse systems. Due to a self-confidence of webmasters we will have a lot of places where OCR may be successfully applied.
We decided to start a series of publications with explanations of how to beat a CAPTCHA. First article is now in the stage of illustrating and preparing to be published here.
This two are not actual, CAPCTHA was changed in corresponding sites
What’s this?
This is one of our OCR systems online demo, the Overture bidding tool CAPTCHA OCR. The idea is to auto-recognize the CAPTCHA images, which does not allow to perform automated search at Overture.
Please note, that this script recognizes Overture bidding tool CAPTCHA images only! Because this one script devoted to this one CAPTCHA. We write new tool for every new CAPTCHA. Online demo is for Overture.
I hope, there is no need to explain, that we have watching tool and any attempt to use this page as a a part of hacking tool will be examined and restricted?
Why not 100% of images are recognized correctly? Because we never set the task to reach 100%. So 99% is enough. If the task is to overcome the CAPTCHA 5% is often enough. This just means that you would have to request page approximately 20 times instead of one. Does it really matter to a script working automately?
One more mobile operator – Jeans. Guys who made this CAPCTHA was inspired by Rapidshare CAPTCHA. But they don’t trace it’s changing – such model was hacked very quickly. Due to color model separating to chars is very easy. Then neural network makes the rest.
Here is new stable and good version of tEABAG_3D. It’s rewritten in PHP5, and works ONLY WITH PHP5. It’s now completely OOP well-made, must be much easier to implement and use. Image if live, it will change with each refresh. As it was promised, all buyers of previous versions can get it for free. Contact us.
