NoCheatPlus
Detect and fight the exploitation of various flaws/bugs in Minecraft!
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 Example video of how NoCheatPlus blocks cheats (outdated plugin version).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.
Recommended
The following plugins might be useful to have a look at.
ProtocolLib
Allows NoCheatPlus to activate packet-level checks, covering a range of exploits that can't be monitored using ordinary means. Since roughly Minecraft 1.7.10, the fight.speed check can't work as expected anymore, due to changes in CraftBukkit. With ProtocolLib this can be repaired.
CompatNoCheatPlus (cncp)
Make plugins like mcMMO or MachinaCraft more compatbile with NoCheatPlus. Not all existing plugins are covered (yet), but you can leave a note or create an issue/ticket request for cncp. Phasing out: Citizens 2 should work with NCP out of the box, MagicSpells are working on compatibility too - rest will be integrated into NCP.
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". (Latest versions of Spigot contain features of Orebfuscator.)

First of all - thank you for taking this up after it went inactive, much appreciated.
I am having some problems with players getting console kicked for destroying blocks. For example - if a player destroys 2 furnaces in a row they get booted on the second one every time.
Is there something I can change to prevent this in the config? I really get a lot of use out of it otherwise.
Plugins used are essentials, mcmmo, swatchdog, worldedit&guard, multiverse, & lwc although we still have the problem when they are all unloaded.
Thanks in advance- I hate having this plugin unloaded in the meantime

Hey developer ;) awesome plugin could you make farming able to without kicks?
Farming sugercane etc. Kicks people automaticly maybe you can blacklist farming blocks?

I'm a bit confused about changing to this from NoCheat.
1. Does it replace NoCheat? or run along side it?
2. Does it have ALL NoCheat features+More or just the Extras.
3. Will it do any harm moving from NoCheat to NoCheatPlus?
@NeatMonster
I would just like to say thank you for continuing this plugin, you are doing a great job, I hope to see some awesome new features, and hopefully you branch off and develop more plugins, seems to be some pretty decent code you are writing.
I believe this is in the default config?
Waterwalk check under blockbreak? Is that suppose to be like that?
If you cut leaves with shares you get kicked for destroying blocks to fast.
Please fix this.
@WizardCM Already implemented, please read the Instructions.txt file.
To everyone else: I'm going to release a new version of NoCheat+ really soon which will fix most of the issues you're currently encountering (especially with FastBreak/FastPlace/WaterWalk). When the next version will be out, please re-enable all the checks you've disabled because of those issues. If an issue is still there, please leave a comment (but only one, not one hundred).
Have another problem. This fight protection doesn't work correctly.
My users use hacks. They can sprint while staying on a place or crouching.
Also, they can block damage and at the same time can hit.
Please, fix it!
Ok as I stated before, to fix the getting kicked fdrom console error, you must disable under blockplace: fastbreak, reach, and direction. This will fix everyones issue.
@mrchasez
Does this screw with heroes? NoCheat used to completely screw with it and it was completely unusable.
Yes we are all aware of the Fastbreak and place @Neatmonster is aware by now too im sure.
@XeonG8
Yes, the problem is in this plugin. Just disable fastbreak and fastplace.
Ok, there is something wrong with this plugin. I disabled fastbreak and fastplace and yes, there is no more no reason kicks.
But seriously, check the code and fix it becouse my options for spam kick are: spam: active: true whitelist: '' timeframe: 3 messagelimit: 3 commandlimit: 12 actions: log:spam:0:3:if cancel cmd:kick
And sometimes my players got kick for one message.
Does this screw with heroes? NoCheat used to completely screw with it and it was completely unusable.
"Player Console kicked <name for Kicked from server"
Ok I'm not sure if this is from NocheatPlus.. but wtf, its happening whenever a player tries to break netherbrick. :S Certainly not a setting I would have made, and not aware of another plugins that updated recently that do such a thing.. its not even logged in the console.
I'm not sure what else could be doing it other than this plugin..
@sexysteve865
No, I don't have mcmmo even I don't know what is it.
@Pr07o7yp3
If you have mcmmo you need to disable the block place, reach, and direction. then type /nocheatplus reload and it will be fixed :)
OK, why this plugin kicks players for no reason? I vanished and followed a player. And he just cut woods and get kicked for no reason...
@NeatMonster
Also, When people are breaking stuff like sugar cane they get kicked for mining too fast I also noticed, On default people can be kicked by placing blocks fast, Not client fast. Just normal fast, i had to put the default setting way down to like 10.
Please fix that too
