    nProtect GameGuard (sometimes called GG) is an anti-cheating rootkit developed by INCA Internet. It is widely installed in many online games to block possibly malicious applications and prevent common methods of cheating.[1][2][3] nProtect GameGuard provides B2B2C (Business to Business to Consumer) security services for online game companies and portal sites. The software is considered to be one of three software programs which "dominate South Korea's domestic online game security market".[4]

    GameGuard uses rootkits to proactively prevent cheat software from running.[5] GameGuard hides the game application process, monitors the entire memory range, terminates applications defined by the game vendor and INCA Internet to be cheats (QIP for example[citation needed]), blocks certain calls to DirectX functions and Windows APIs, keylogs keyboard input[citation needed], and auto-updates itself to change as new possible threats surface.[1]

    Since GameGuard works like a rootkit,[2][6] players may experience unintended and potentially unwanted side effects. If set, GameGuard blocks any installation or activation of hardware and peripherals (e.g., a mouse) while the program is running. Since GameGuard monitors any changes in the computer's memory, it will cause performance issues when the protected game loads multiple or large resources all at once.[7]

    Additionally, some versions of GameGuard had an unpatched privilege escalation bug, allowing any program to issue commands as if they were running under an Administrator account.[8]

    GameGuard possesses a database on game hacks based on security references from more than 260 game clients. Some editions of GameGuard are now bundled with INCA Internet's Tachyon anti-virus/anti-spyware library, and others with nProtect Key Crypt, an anti-key-logger software that protects the keyboard input information.
