Re: An example of encrypted functional shellcode

Just pointing out things: // function that decrypts the shellcode void decode(const BYTE* key, BYTE* code) { int i; for(i=0;i<=strlen(code);i++) code[i]=0xFF&(key[i]^code[i]); } You know strlen gets the length of a null terminated string, what happens if your encrypte...

Re: A program example to mark an executable with an md5hash

Lol, this post is an example for beginners, and it is meant as a cross platform example for beginners to play with self modifying code. Its a level 0 stepping stone :P you should check out some of my other posts ;) like this one lol: https://www.hackthissite.org/forums/viewtopic.php?f=156&t=1195...

A hello world for encrypted binary obfuscation

So I have been asked many times about this, in fact the concept is SO popular I got tired of hearing people ask about it lol. So without further a do, lets get started :D Binary obfuscation is the art of obfuscating code so that reverse engineers have a hard time understanding your code either in a ...

Re: You even get the source code!!!! piece of cake huh? :D

The challenge was spoiled, here is the source code for it so that you can play with the concept. the answer was "noob :P" base64 encoded, and split up between opaque predicates ; ---------------------------------------------------------------------------- ; "THE BEER-WARE LICENSE"...

Now, I do agree that you were treated badly by some other users, and that it's not right, but it's ...
