Metin2 packet encryption algorithm

09/12/2026 11:34 blacklogic#1
Hello, i am new here.
I want to build Gameforge metin2 packet sniffer but i don't know its encryption algorithm and private keys.
Could you help me obtain up-to-date information?

Have fun...

Private keys? What?

Gameforge has some kind of own protector-VM (CheatBlocker (CB.cbm)) so you can't see everything depending on what you want to access.

No reaction to either Procmon or unsigned no op dlls. So there isn't much detection client side.

But i do got banned after some testing phase for a waithack while i access the monkey dungeon the first time.

I did send around 1700 requests on the server for enemies out of range (tried to see what happens). Therefore they just log some things and might check on certain thresholds.

No loader inline hook on CreateRemoteThread too. LoadLibraryA works fine too.

So your're saying they do not check those functions for hooking?
