Are you sure you didn't use UPX?

yes i updated it right after posting.. Why: if you cant unpack the crackme, then you cant crack it at all!
:)
its not scrambled though.

no external compressor tools or so used

Edit:
use them only for testing, and never distribute a program that is packed with them! There are known bugs.
:wink:

Notice thats not the case with UPX :)
only with the others.

if you are too stupid (joke :)) to unpack it, then i can upload an uncompressed version too heh

hint: download the latest upx and decopmress :)

I had already decompressed when I posted that. It meant that I found out that you were using the beta version of UPX.

Where is the easier ones? This one is too difficult for a beginner. (I've never tried anything like this before.)

@trond and other beginners: This is the level 1. Its easy :D

File:1->thefools_crackme_-_part_1.exe

edit: Its educational to crack them! This is the simplest one. No protection at all! next one will be a bit harder.. but ill give you some time to solve this :D

Ok, here's the solution to the easy one. It was at the border of my capability but I got it. :)

Actually, the problem was neither to find out the password nor to find out what I had to replace with what in memory, but to find out how to make the disassmbler show me the position in the file instead of in memory. :lol:

Patch: crackthefool_1.exe

Edit: For number 5, do you think that you would be able to crack that one if you didn't write it yourself?

hehe... really to simple ;.)

the MD5 of the password is: e431f1c08f6c24e63bc4390fcfe06a69
(you can try to crack the MD5 if you want, lol)

But it CAN be cracked.
