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

Drop HackedServer.jar, HackedCore.jar and (for 1.17+) ProtocolLib into your /plugins/ folder.
Restart your server.
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.
