PluginSpoofer

Reduces plugin detection and avoids exposing the real environment. *Logo generated by Google Gemini (Nano Banana)

PluginSpoofer is a Bukkit/Paper plugin based on PacketEvents, used to intercept common probe commands, filter command tree completion, and return a configurable list of fake plugins.

Why Do This?

Many servers are probed for their plugin stack using methods such as /pl, /plugins, /version, /about, and command completion.

PluginSpoofer's goal is not "absolute security," but rather to significantly increase the cost of detection and reduce the risk of script kiddies easily understanding the configuration.

Core Functionality

Supports intercepting blacklisted commands (e.g., /plugins, /pl, /about, /version, customizable)
Supports high-version command tree filtering and Tab completion filtering
Supports forging /plugins / /pl return results (distinguishing between Paper/Bukkit styles)
Non-plugin list blacklisted commands follow the server-side native Unknown Command process
Retains the original command name in the Unknown prompt to avoid exposing "command replacement traces"
Management commands /pluginspoofer and /ps are hidden from the command tree by default

Dependencies
