This is a great challenge. I encourage anyone active in the section to have a go!
HINT: Notepad++ might help highlight some clues for you if you are unpacking the .exe correctly. :)

It certainly is a tough one. Packed plus multiple (hidden) threads which detect debuggers. I might work on that later just to get more into x86. I don't really care about the files.

I did tried for roughly an hour. I couldn't spare more time. I mainly did it just to get more into assembler. Iirc, I saw a clear interrupts instruction, which I would be odd. I'll look into it again some other time.

@RevEngKal dont waste your time this crack me is boring, since it uses a commercial packer that runs the assembly inside a VM. One would need to find a unpacker for the packer that revo used and start from there, but no, real crack me challenges are small (<50kb) and dont use a packer VM thingy, they rely on smart self written anti debugger tricks, some puzzeling and data hiding, that are the funny ones. If you see any bigger executable just skip it.

Isn't writing an unpacker just another part of the challenge? I figured out the packer, but never bothered reading up on it.

Nope, because commercial packers have a big team in the background getting paid to secure executables. It takes weeks or months to write an unpacker for it, but that has nothing todo with a crack me challenge, since everyone could just put any exe into a packer an call it a crackme challenge, but where is the challenge then? Revo just used a packer for which no unpacker exist as of today, this is the reason why he also time limited his challenge. Someday in the future there might be a cracker team that write an unpacker for it, but again thats not a crack me challenge, its just using a commercial packer. You find crackme challenges all over the internet, they are very small, self written by devs, with different difficulty levels. I dont know who that revo is, but it seems as though he totally missed the point of a crack me challenge. If he want he can contact me and i could help him to write a proper one, depending on his x86 assembly knowledge.

I usually just unpack my EXEs using Olly+Scylla. Worked for UPX and PE Compact so far. The are guides for Enigma as well. You're right though, just packing an EXE is kinda lame, as anyone can do it.

it's packed with Enigma 5.9 .. title should be "unpack it" and not "crack it".
also i don't see the challenge when you throw an exe into a packer and post it here to check whether anyone can "unpack" it or not.
it'll be more interesting posting an exe with self-made encryption/protection system then it can be called a "crack it" challenge.
