Well, iirc, there used to be a program to crack it.

well it's a part image and part is normal characters (or digits)
Or if it's a full image png so there isn't any tool or project can read it as it's png pic
but anyway i don't look for it Cuz of if the gateway give the image captcha as a digits then the client convert to png pic so there's a way to make a tool to read the captcha (from collecting the data wich coming from gateway to client) but if the gateway is the creator of the png so u can't by anyway ,,
But i was in past using a tool wich read the captcha then write it and click confirm and login (as auto login tool) .
i don't read

well , but i got that the gateway send the image digits to client then the client convert to png .

A real good captcha can't be avoided, unless you make a good recognizer but It will be a very slow system...

Nezekan · 11/27/2011, 22:21

In either case, a decent ocr system would do the job

good captcha can avoided as isro before there were more than 1 tool and gold botters was using it , so joymax knows that captcha won't make anything with those tools wich read the captcha so they delete captcha and make auto login .

SRO doesn't use a good captcha. A good captcha is almost by definition a captcha that can't easily be recognized (using OCR/captcha breaking applications).

Anyways, I'm pretty sure it's only a PNG. Joymax wouldn't be so stupid to send the captcha (or a part of it) to the client as plain text.
Like Drew said in his thread, it's just compressed (using an algorithm specifically designed for images) and packed (using ZLib).
