Detecting Hacked Clients at Connection Time

Running a public Minecraft server means dealing with cheaters, hacked clients and unfair mods.
HackedServer is built to catch them as early as possible: at the moment they connect.

Why detect at connection time?

Instead of relying only on classic in-game anticheats, HackedServer inspects specific packets exchanged when the player joins.
This allows it to:

• Detect many clients before they have time to toggle any cheat
• Reduce noise for your staff (fewer false-positives from movement checks)
• Give you a clear list of suspicious clients and mods

What can HackedServer detect?

Depending on your server version, HackedServer can detect:

• Forge and many Forge mods
• Fabric and Rift-based clients
• WorldDownloader
• Labymod, BetterSprintingMod, Liteloader
• 5ZigMod, PX Mod
• Vape Cracked and more

You can also add your own custom checks to extend detection as new clients appear.

Getting started

1. Drop HackedServer.jar, HackedCore.jar and (for 1.17+) ProtocolLib into your /plugins/ folder.
2. Restart your server.
3. Follow the configuration guide in the docs.

You can read the full installation guide at https://docs.hackedserver.org.

That's it! This is a minimal example to get you started.
