    I have tried to break some captchas and I managed to write some small code which works very well. The problem is it works only for one specific captcha (from folderblog) and only one specific image.

    I couldn't be bothered writing the code to post spam on the comments but I decided to make it accessible to you guys.

    PM me for access details.

    I also have a nice list of websites suitable to spam.

    I am setting up a few captcha breaking scripts. Each can break one specific captcha (and yeah I know that they are not very sophisticated captchas).

    Not sure if anybody wants access to them. If so let me know and I will explain how they work.

    well it's a really simple script and thats why it can only decode simple scripts.

    First you need to set up a small config file.

    width and height of chars, where first char starts, how many chars and what type the image is.

    The script then basically crops each char and stores it. In the beginning when it doesn't know any you just need to look at the crops name them with the char that is visible and copy them then into a folder. Once you got all letters it will work 100%.

    When it crops and stores a char it compares it with those in that specific folder.

    It works nice and quick.

    But like I said it is only very simple.

    Alright got it, but I don't think this can work for captchas like the ones on myspace (I mean with the distorded letters), can it?

    no. unfortunately not.

    But I am trying to find code and other resources that will hopefully enable me to do that in the future (maybe very very very distant future.
