AntiCheatObfuscator

This plugin creates a smokescreen of fake commands, making it significantly harder for cheaters to identify the actual anti-cheat systems in use and enhancing your server's security.

Real-World Effectiveness Examples

Chat example:

• HackerM: I found that this server has 4 anti-cheat plugins!
• HackerM: Matrix aac vulcan ncp
• HackerM: I think I can try to use the anti-cheat vulnerability to fly
• However, the server actually only uses grim matrix and vulcan

Key Features

Fake Commands: Registers fake commands for popular anti-cheat systems including Matrix, Grim, AAC, and others. This helps conceal the actual plugins being used.

Configurable Commands: Easily enable or disable specific fake commands through the configuration file. You can specify exactly which commands should be active.

Auto-Completion Support: Enhances user experience by implementing auto-completion for fake commands, allowing players to use them quickly and accurately.

Admin Notifications: The system alerts administrators when players attempt to use fake commands.

Packet Obfuscation: Sends fake packets to hide information from hackers! (New feature)

Packet Obfuscation

Packet Obfuscation (experimental): This new feature improves anti-cheat effectiveness by sending obfuscated packets with randomized action numbers. It helps conceal detection mechanisms and enhance cheat prevention. Note that this feature is experimental and may affect server performance.
