Earlier today I was asked for a way how to write self modifying code. I remember I had once written a small crackme using this technique, and against all odds I was able to digg up the source code :)

So without further delay, a very small example of how you can write self modifying code :

Level : beginner

one thing: save the humanity!

tools: softice for all:))

DETTEN CRACKME #10 download here
******************

Tools: Softice, Procdump, LordPE, Hexeditor, Filescanner
Level 1-10: 4



The first part of this tutorial is about unpacking Aspack 1.08.04 by hand to get the program's listing. Then we reverse the algorithm and finally code a keygenerator.

Level : 1/10
OS : windows
Language : vb



Very Easy CrackMeWhile trying to figure out another very easy crackme I was messing with VB.

I ended up making my own CrackMe (very first!!!! )

This is very easy, initially it was too easy, first BP and serial was sitting in your face lol, so I added an extra compare (hint)

Level : newbie

Well I am an EXTREME NOOB!!!

I ran across an issue while exploring a crackme.
I opened the Crackme in Numega's SmartCheck;
Ran it and Smartcheck closed.
I repeated the numerous times ;)

So, it must be some kind of Anti SmartCheck coding I figure, but how to get around it?
