If the game server detects a delay or anomaly in the heartbeat packets, it will disconnect the client within minutes.
Detects patterns common to debuggers and macro tools.
NProtect GameGuard is a software-based security solution designed to protect online games from cheating, hacking, and other forms of malicious activity. Developed by NProtect, a South Korean company, GameGuard is widely used by game developers to safeguard their games and prevent unfair play. The software works by monitoring the game's memory, detecting and blocking any suspicious activity, and reporting potential threats to the game developers.
