[UnpackMe+KeygenMe] BitLocker #1

[LulzCoder]

Hello Everyone,

 

I found a nice keygenme and unpackme on http://www.rohitab.com/discuss It's coded by BitLocker, so all credit goes to him.

Thought it will fun to solve, thus posted here. Rest about level, see yourself and decide Rules :
1. Unpack the EXE
2. Write a valid Keygen
3. A TutorialOut of rule :
1. No self keygenning
2. No modification in main EXE in any condition

 

If you think I am uploading here to get this solved for myself, then you are wrong.
Here is my serial :
Name : LulzCoder
Serial : OEYyQS1EMDFFLTVDRUEtQjQwQg==
 

UnpackMe+KeygenMe by BitLocker.zip

Any crackme that generates correct serial and then makes rule "no selfkeygen, no ripping of code" is a boring crapme.

 

My serial (I can't actually test it, as it won't run on my system at all and I'm too lazy to debug it):

I guess how youv'e unpacked this ? May I have a discription ? It was not packed on rohitab (original one), and before uploading here I packed it.

I did it the standard way:

1) find oep - quite easy, the trick with memory access violation and SEH was a giveway;

2) dump from memory. PETools work;

3) fix 3 imports from GDI32. Imprec Trace Level 1 took care of that;

4) done.

 

I'm sure there are also several tutorials and scripts for Yoda Protector (if that's what you used). Just search the forum.
