UnsoulExploits

🛡️ 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.
