Announcing AntiSpoof v1.0.2: Advanced Client Spoof Detection for Minecraft

I'm excited to present the first official release of AntiSpoof! This powerful Minecraft plugin gives server owners unprecedented control over detecting client modifications used by players.

What Does AntiSpoof Do?

AntiSpoof provides robust tools to detect and respond to client spoofing attempts through:

• Client Brand Analysis: Block/whitelist specific client brands (Fabric, Forge, etc.) and detect suspicious formatting
• Channel Monitoring: Verify vanilla clients and implement channel whitelist/blacklist systems
• Bedrock Integration: Seamless Floodgate API support with fallback to prefix verification

Key Features

• Multiple Detection Methods: Various checks can be enabled/disabled independently
• Configurable Response System: Customize actions for detected spoofing attempts
• Bedrock Player Handling: Special modes for cross-platform compatibility
• Admin Tools: In-game commands to inspect and monitor player clients
• Debug Mode: Detailed logging for troubleshooting false positives

Important Notes

While AntiSpoof enhances security, it's not foolproof. Experienced players can potentially spoof client details to bypass detection (ironic, I know!). By default, the plugin only checks whether a player claiming to use 'vanilla' has registered plugin channels, something impossible on a true vanilla client.

Server Requirements

• Java 21+
• Spigot/Paper 1.20.4+
• PacketEvents 2.7.0 (included in the jar)

Optional dependencies include Floodgate (for Bedrock support), PlaceholderAPI, and ViaVersion/ViaBackwards.

Getting Started

1. Download the plugin jar
2. Place it in your server's plugins folder
3. Restart your server
4. Configure via the generated config.yml file
