NoCheatPlus

Detect and fight the exploitation of various flaws/bugs in Minecraft!

Main Features Permissions Commands Configuration Jenkins

Introduction

NoCheatPlus attempts to prevent cheat clients from exploiting weaknesses of Minecraft or its protocol, making your server more safe. Checks cover a wide range of issues including flying and speeding, fighting hacks, fast block breaking and nukers, inventory hacks, chat spam and other types of malicious behaviour. For a more complete list have a look at the Features Page.

NoCheatPlus puts emphasis on configurability and allows you to customize actions that are carried out when a player fails a check (e.g. silent cancelling, executing commands, just logging). Bypass permissions allow to control what check to apply for which players, all checks can be deactivated in the configuration, also having the option for world-specific configuration files. Many checks allow more detailed configuration to adjust sensitivity.

Certainly NoCheatPlus is not a magical bullet, it uses a lot of heuristics and even guessing, so you will encounter false positives here and there and also not catch every single violation. Example video of how NoCheatPlus blocks cheats (outdated plugin version).

NoCheatPlus was introduced by NeatMonster, building on the code base of NoCheat by Evenprime.

The following plugins might be useful to have a look at.

CompatNoCheatPlus (cncp)

Make plugins like mcMMO, Citizens, MagicSpells or MachinaCraft more compatbile with NoCheatPlus. Not all existing plugins are covered (yet), but you can leave a note or ticket request for cncp.

Orebfuscator

Orebfuscator fights all sorts of X-ray-hacks by altering the map information that is sent to the players, such that they have to mine blocks to actually reveal what is behind. Virtually a "must have".

    i edited my comment but idk if you'll see it so ill just post it here just in case. after extensive testing we nailed the problem down to the bukkit server. 1.3.2 r0.1 and 1.3.2 r0.2 people can effortlessly block jump, when we moved to 1.3.1.r0.2 people suddenly couldnt block jump anymore...

    if you still want me to make a ticket i will

    using no lag examine, this is the laggiest plugin on my server. The playerMoveEvent

    This is however on a 250 player server. Would it be possible to fix it around so there is less lag?

    @twisted067: Go

    Please make a ticket for that exploit and give a little more information like version (build number) of NCP and CraftBukkit. Also what kind of protection plugin you are using.

    @VietNg: Go

    Outdated version in use, download the latest version of NCP, please.

    @asofold: Go

    asofold, yes, block jumping is possible. Me and another admin tested it extensively and cannot get to the bottom of this. We even got a fresh config and see if that would fix it, and played with the settings but nothing would fix the block jumping. We're resorting to putting up no entry regions everywhere. Idk if its just us, or if others server have this problem too. We haven't recent put any new plugins on, but we're probably gonna start taking them off 1 by 1 to see whats up.

    edit: after extensive testing we nailed the problem down to the bukkit server. 1.3.2 r0.1 and 1.3.2 r0.2 people can effortlessly block jump, when we moved to 1.3.1.r0.2 people suddenly couldnt block jump anymore...
