hello,

Today i've a problem  with GSA Captcha Breaker. When i edit the filters in the SDK The OCR 2 can read perfectly the text but when i tried to test with this : http://localhost/gsa_test.gsa it said "[Unable to break this captcha sorry.]".....

Please can you help me?

best regards,

    hmm maybe the image type is not correctly set for that captcha type? Was it identified correctly?
  • VialaxyVialaxy
    The image type is set as png and i only send png to the test page.
    But i have i tested with an other filter (exactly the same parameters) and this one work perfectly...
  • SvenSven www.GSA-Online.de
    ok then it's the way you designed the solving. has nothing to do with a filter working or not. Maybe you used to few captchas to design the type.
  • VialaxyVialaxy
    Ok. Is it possible to "train" gsa captcha breaker?
  • SvenSven www.GSA-Online.de
    sure, get me some captcha samples and I try to optimize it.
  • VialaxyVialaxy
    Ok tnx :)

    It's much better now (with 40 captchas) for the brute force ^^

    But is it possible to add some captchas samples and make GSA "learn" these captcha?
    Just learn not try to filter do decode them?

    only if you use the Mask as method.
  • VialaxyVialaxy
    and is it possible to use 2 method at the same time?

    one witth the mask and the other with the filter for "unknown" captcha?
  • SvenSven www.GSA-Online.de
    yes.

    I tried but it often say: [Unable to break this captcha sorry.] in partiicular for long captchas...

    And for the mask they said that i need to use segment or sagment and rotate at last filter but when i did that i cut 50% of  my captchas wrong so sucess rate is at least 30%...

    Any suggestions?




  • SvenSven www.GSA-Online.de
    what you mean with long captchas? Is the length of the answer different sometimes and not 5 chars in length?
  • VialaxyVialaxy
    Yes, the captchas can be like that: http://hpics.li/f8de00c or like that: http://hpics.li/236c69b ...


  • SvenSven www.GSA-Online.de
    OK so obviously some other captcha, not the one from op. If you get me more samples or place to dl it from, I might be able to make a good definition.
  • VialaxyVialaxy
    Ok thanks :)

    I've save all the captcha that gsa try to resolve: https://dl.dropboxusercontent.com/u/44630649/CAPTCHAS.zip

    Around 110 captchas...
  • SvenSven www.GSA-Online.de
    does the " " have to be in the result or can it be skipped?
  • VialaxyVialaxy
    they can be skip :)

    and the site don't care of the letters: it can be LiKE this or liKe this...
    And there is 1 error possible per captchas :)
  • SvenSven www.GSA-Online.de
    have it to 60% by now. Though some captchas are with to chars joined together and so those might not be solvebale.
  • VialaxyVialaxy
    Yeah, captchas with i are hard to solve because theyre most often joined with the previous chars :/

    But with all this captchas i tried a bruteforce and i can reach 88% :D

    But there is no option to use the mask or fixed result methods?
    Importannt: pink line are always generated randomly even for the same captchas 
  • SvenSven www.GSA-Online.de
    using mask is possible but if you got it to 88% already...then why bother?
  • VialaxyVialaxy
    To make gsa learn hard captchas like this one: https://dl.dropboxusercontent.com/u/44630649/48856_6454109.png
