Hi guys.

Ive got a .dll that when i inject i need to give it a name and Key number.



Running PEiD i see this=


So i figger I cant get/Make a keyGen for it...The protection seems way to high for a nooby like me.

I could just unpack it -(Somthing Im working on ) but it seems a Key gen would be some much easyer...then again could u guys give me some advice ?

I can upload the .dll if u need to look at it.

If Arma uses this key for the decryption of the 'protected' routines/functionality, cracking it without a valid key is virtually impossible (only option is bruteforcing). With a valid key it can be 'unpacked' and have it's fingerprinting removed ... Search the forum or search ExeTools / Woodman / ARTeam, there is much info on Arma's hardwareID fingerprinting around ...

Yeah did that.

Almost everyone at other forums from ARTeam - exetool said it cant be cracked....It appears its Crack proof %100.

Oh well thxs for the reply.

Maybe i should upload it to the crackme section?

Crackmes are programs written specially to be cracked (usually written by reversers for reversers) and they are not crack requests.

You're right; without a valid key it's virtually impossible to decrypt, but with a key it's relatively easy for the pro's Mr. Green

A little info on how you managed to crack it, what techniques used, what the protection was and what weaknesses it has, ... would be interesting for the other readers.

Well this .dll was harder to crack then a Virgin on heat.

I dont want to share the info as yet....Mainly due to the fact that this was a hack for a game(Not public) - And only now can I repsect the makers of it for having sush HARDCORE protection.

I dont no the guys that made it - So i have to respect there code.

I have afew more .dll's to try and crack - With almost identical protection and if all goes well -yeah a tutor may come..

For now its private for the right reasons.

Main Protection -http://siliconrealms.com/index.shtml
Tools - ollydbg -hacnho tools -MedicKitools- ollyscripts -SoftIce Exclamation
Tutor - http://www.absolutelock.de/construction/files/infobase/New/arma_debugblocker/tutorial.html
And afew others i downloaded.

It sounds like Armadillo Standard + Debug Blocker, without the fingerprinting decryption-stuff discussed above (since that really requires a valid key for decryption of the code first). Have you scanned your target using haggar's updated external PEiD signatures or with Armadillo FindProtected 1.2 ? It would be nice to know which Arma version and which Arma options are used ...

Please remember that most reversers here are mainly looking for knowledge and not cracks (since we all know howto download stuff and if the game is any good it will problably be cracked & downloadable within 24 hours anyways) .. so any tutor without giving away the target itself is still much appreciated Wink
