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 detect changes to the game environment. It supports major and proprietary game engines and offers game-specific countermeasures. Components can update frequently, including in the background while players are playing. A publisher or developer must integrate PunkBuster directly into a game's engine; it cannot be used with a game lacking 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. PunkBuster creates a player GUID from the game CD key using a 128-bit one-way hash, so the key cannot be computed from the GUID. The maker offers PBSetup for manual updates and a Windows service installer for required services. Players can submit web-based trouble tickets, and player and administrator manuals are available. Founded in 2000, PunkBuster is headquartered in Austin, Texas, United States.
