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 Example video of how NoCheatPlus blocks cheats (outdated plugin version).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.

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.)

Like my last suggestion to evenprime before he left.. was a way to redirect the NC spam (that they generate) back to that player, with a permission for a demoted rank or direct command...
would be good :D i do like trolling and nothing easier than reminding a player that I know what they are doing by giving them the same spam, save me time telling them wtf it is that they are doing to annoy me. So yeh please add that, would be a good time saver aswel.
Not sure what page to comment on but awsome job picking up this plugin...its essential. I use this new plugin jar and it deleted the old nocheat config file and didn't create a new one. I also gave nocheatplus.zombe.fly node/perm to moderator group and they cannot fly using zombe's.
EDIT: was i suppose to delete the old nocheat.jar?? because I did and put your nocheatplus.jar on the server only without nocheat.jar
@Poopfish Thanks! The old one still works but I've added new features. :)
@Confuzzled77 Thanks! You are awesome for leaving a comment! :D
Thanks! You are awesome for picking this up!
Thanks for updating this, the previous one still works as far as I know, but thanks for picking it up
@sexysteve865 @cydrobolt A first version is available for download. Keep in mind the new check (WaterWalk) is experimental (it has worked fine during my test but we never know). If you find a bug or have any suggestion, please feel free to leave a comment here.
Can't wait either, do you know when its coming out? :D
I can't wait :)
@7007King0770 @PixelTator Thank you both.
I'm trying to add a new check to prevent "WaterWalk".
Thank god for this sir. I commend you.
I cannot (well technically I can) wait for this plugin to have a stable version!
@kahlilnc You're welcome!
Yay! Thank you for picking this up.
@pimsserver No download is available at the moment. I'm still working on a complete code rewrite.
@JWNJWN I'm already registered at HF, it's a really good place to find hacked clients. :)
Hey sign up at hackforums.net since there is usually alot of mc hacks released there
any idea when i can download this?
@QweSteR2221 I've already looked at this project and talked with its author: we have decided to do not work together. But thanks for the reply. :)
