DSGuard

dsg

DSGuard (DSG) it’s a product  that works as a client-sided anti-cheat for a game-Cabal. It has been adapted for 2 more MMORPG games so far.
Most part was written in C++ and some other parts were written in C#.
To develop this app I used Visual Studio, Ollydbg and RadASM and part of the features are:

  • file integrity checking (hashes)
  • memory scanning (for value manipulation)
  • process scanning (for hooked dlls)
  • hack attempts log record

Ollydbg is an excellent debugger and I used it for research and testing and manually hook the DSG dll. I can not provide more details due to security reasons.

Some key features were inspired by my friend Kai Philipp, who also helped me designing other apps.
