🛡️ UnsoulExploits – Advanced NBT & Packet Exploit Protection
UnsoulExploits is a lightweight yet powerful security plugin designed to protect Minecraft servers from NBT-based crashes, packet exploits, and malicious client abuse.
Built using ProtocolLib, this plugin intercepts dangerous packets before they reach the server core — preventing crashes, lag exploits, and NBT bombs.
🔥 Why UnsoulExploits?
Many Minecraft servers are vulnerable to:
- NBT nesting crashes (StackOverflowError)
- Book JSON bombs
- Creative mode NBT abuse
- Oversized packet exploits
- Malicious custom payload attacks
UnsoulExploits acts as a security layer alongside your anti-cheat to stop exploits before they break your server.
