PunkBuster

What PunkBuster is
PunkBuster is an anti-cheat system for online games. During gameplay, it scans computer memory for signs of loaded cheats, checks game integrity, and can identify changes to the game environment. It supports major and proprietary game engines and offers countermeasures for individual games. Its components can receive frequent updates, including in the background while a player is playing. PunkBuster must be integrated directly into a game's engine by its publisher or developer; it cannot work in a game without that integration. Server administrators have tools for screenshots, logging, streaming, and remote access. The optional MD5Tool checks configured files during gameplay, but is off by default because disk access can cause minor hanging, stuttering, or lag. The maker says it derives a player GUID from a game CD key using a 128-bit one-way hash, so the key cannot be computed from the GUID. PBSetup is available for manual updates, alongside a Windows service installer for required services. The maker also provides player and administrator manuals and a web-based trouble ticket option for players. PunkBuster was founded in 2000 and is headquartered in Austin, Texas, United States.
