What do you mean by "coded"?

If you mean that it has been encrypted, I think there are a few methods to beat that.

If you mean a recovery of the original source code... no chance.

whats with that attitude ? your a mod ... grow up. thanks

If you want to get the source from a compiled file you have several options :

- use .NET Reflector (if the app is coded in .NET)
- use a Disassembler (to disassemble the file)
-- Use a tool that creates pseudo code out of assembler
--- Like HexRays Plugin for IDA and stuff

Im using ollyDBG but i tried to open the dll or that injector and it crashes and for the dll it sayes it is not 32bit cause its coded and unreadable! With IDA i have only one problem, it dont let me save to EXE or DLL! Really sorry for the poor english but i hope you understand what i woudlike!

You will never get a full original recovery of the source code. That's just not going to happen. I didn't say that there aren't a few good possibilities to recover bits of code and find out how the program works.

So please grow the **** up.

How did you become a mod btw? All I see from you is german colloquial and kiddie flames...

You dont call it coded you call it crypted and watch at the end of the code. You will often find there what it is crypted with and then you can search how you can decrypt it.

Yes, you may feel pleased now.
FYI: You can't simply bypass that client thingie. Don't even try unless you have all parts of it!
If you don't even have a clue what I mean by saying "all parts", keep on reading...

Well, since I don't feel like downloading it, I didn't try myself, but a friend of mine told me about it. I think it's pretty similar to an updater I used a couple months ago. The underlying idea is to hide the path to the actual file, which would be injected later, as well as possible. Yes, that and of course making it possible for those who bought this hack to log in somewhere and to get the hack itself (a so called user interface, bla bla). The main principle would look like...
Code:
C->S   Requesting some kind of a status
S->C   Answering with a message
C->S   Requesting availability of the given login data
S->C   Answering with a cookie, if the data was valid
C->S   Requesting the file, cookie included
S->C   Answering with the [I]encoded[/I] file*, if the cookie was valid
C      [I]Decoding[/I] the file and injecting it after


While S would be the server sided script (that's what I meant by saying "unless you
have all parts") and C the client sided complement.

* = When coming to this step the script reads the file bitwise and shows its contents,
    which are [I]a little messed up[/I]. The file as such remains in a folder you don't know
    and wouldn't have enough rights to read from anyways.

BUT you're still a pretty lucky guy, because you already have the encoded file. Even a six years old child, which is blind and totally retarded, would be able to manage decoding it. But here is a hint for for, just in case you are a little slow:
Code:
        ... -0x03 -0x02 -0x01 -0x02 -0x03 -0x04 -0x05 -0x06
-0x05 -0x04 -0x03 -0x02 -0x01 -0x02 -0x03 -0x04 -0x05 -0x06
-0x05 -0x04 -0x03 -0x02 -0x01 -0x02 -0x03 -0x04 -0x05 -0x06
-0x05 -0x04 -0x03 -0x02 -0x01 -0x02 -0x03 ...
And yes, I made a conscious decision for this exposure (making it even more obvious for all of us).


Oh and by the way... please do NOT think I am selfish, I just like to provoke others... hit me *meh*! <:0
