ServerCrasher
ServerCrasher attempts to crash a remote server by exploiting known vulnerabilities in specific Minecraft server software versions and plugins. Each mode targets a different bug, so the right choice depends on the server software and version you believe are running. The module will refuse to activate in singleplayer and is intentionally excluded from auto-configuration presets.
Most modes fire a one-shot attempt the moment the module is enabled and then disable themselves automatically. BundleExploit-1.21.4 requires you to be holding a non-empty bundle item in your hotbar when enabling. PaperWindow-1.20.1 and GrimConsoleSpammer run continuously — sending packets every tick — until you turn the module off manually. TranslationSign-1.8 intercepts the next outgoing sign-update packet you send, meaning you must edit a sign after enabling the module; it also requires ViaFabricPlus with the connection set to protocol version 1.8.
Several modes — WorldEditCalc, PermissionsEx-Promote, EssentialsPayStar, Log4jChat, and Log4jTell — are retained for historical reference but are widely patched and highly unlikely to work on any modern server.
