    Default 3D Captcha

    Hello People,

    After lots of reading and searching, I decided to start a new Thread. I want to make an auto bot for a game called Omerta/Barafranca. Well, it doesn't matter for which game it is at all.
    I followed some tuts, and I'm good enough to write some scripts with SCAR now, and I allready wrote a script, but now Omerta changed the codes and I don't know how to hack these.
    I asked Markus and he wanted to help me (thanks alot for that), he told me about Sleepwalker and it sounds like a good idea, so I hope that Markus and I are gonna succeed. But I can't live with it that it's impossible to hack that captcha. So that's the reason I decided to start this new Threat, and I hope that we together are able to hack this captcha.

    Well, I think that I've talked enough now, lets start!
    You guys can't help me without seeing the captcha so here he is:
    Omerta Captcha
    Well, I guess this are all the different ways the captcha can be (except that it changes color all the time, and sometimes its almost flat and another time it almost stands vertical).

    Well, as said before I only know something about scar, do you guys think it's possible to hack a Captcha like this with scar?
    If yes, how?
    If no, wich program should I use then?

    Well, thanks allready for reading this, I really hope you guys can help me.

    Bye,
    Wouter

    How about you use PhotoShup, make a few images with the numbers/letters, and Batch Edit the lines and stuff in?

    @ Hy71194:
    Sorry, I don't really understand what you mean. If you mean that I have to make an image of all letters, I don't think that's possible, cause there are very much different letters in this captcha (look at my example, there are 3 different J's).

    @ Mastaraymont:
    Thanks

    Ok, at the register page of Omerta/Barafranca you can see the captcha, so if you need to see it: Look Here

    Fist you need to save loads of those images. Then you must compare them, see if the letters are the same... If not, you will have to make a DTM for every possible captcha

    I've tried for ever to make a working one for myspace and i got nowhere.
    But this one seems to be easier.
    And if i know anything about SCAR, i know anythings possible.
    I used FindDeformedBitmapToleranceRotationIn and made bitmaps of all the letters.
    It searches for a bitmap and if its not found it turns it some and searches again.
    The deformed part means they dont have to match exactly either.
    But myspace makes their captchas too crazy and overlapping and it wouldnt seperate the letters.

    I don't think it's possible for SCAR to catch a CAPTCHA. ;o

    Well, I can't program C++ or Java, so I think I'm gonna make an OCR with scar, I'm gonna try to get all the fonts and make bitmaps of each letter. I know it's crazy but I don't know how to do it more simple..
    Comments are still welcome

    Making a bitmap of each letter won't work... I'm almost positive.

    Jeah, I'm now making DTM's...
    But it's very much work
    I guess there are over 50 different fonts, so 50x26=1300 DTM's
    So even if I succeed in making it, it would be very slow I guess..
    No other ideas ?

    Dynamically means 'do they keep on changing'.

    Well, I'm still figuring that out too. I know have got around 100 captcha's, and there are some with a same font I think..
    But they almost change always, so I think they are "dynamically".

    [EDIT]
    Here's where you can see it (it's at the register page of Omerta):

    They change dynamically how? Random camera angles, random elevations, etc?

    If so, you have a lot of work on your hands...

    But hey, good luck

    I am not sure but I think a program called Teacup or something to do with tea or maybe that person that told me was JK...
    anyways...
    Yes Different camera angles and rotations and different elevations and fonts.
    All that good stuff...
    So I'm just gonna look around see what I can do to find out how to categorize them...

    EDIT: Ok... I didn't do much but here is 162 captchas I copied about 4-6 months ago...
    I think they are the same now...

    Captcha Pack Download

    I organized into two groups, one with them slanted down and one up.
    (BTW: They are dynamic so if you get one(on the website) that has same code it will look different anyways(from what my pack includes))

    I hope you're using a bit of area tolerance on those DTMs, w0uter...
