RedProtect will be a new feature for my server RedMS. Yes I am Mikey the original RMS owner(Youtube up RedMS, if you don't know).
Features:
Packet editing detection(Detects all winsock & MapleStory hooks)
Memory editing(VirtualQueryEx(); is my hero!)
Dll injection(:3 I'll keep this a secret)
Hook detection(Detects hooks)
Everything is controlled by the server, the whole module is virtualized and heavily encrypted. The server will send random heartbeats at random time, and will require a heartbeat response back to continue to play the server.
Everything is done... I just need to include timestamps on packets. Be sure to keep an eye on this thread :)
This is the response handler I've coded... I'm keeping the clientside response as a secret.
