Wither Anti Cheat | 1.13.X - 1.16.X | Paper, Tuinity Support | Free, Accurate, Optimized Anti Cheat

WAC is my old anti cheat which I don't actively develop anymore (however I will still make sure that it keeps working). I recommend checking out my new anti cheat Themis (also free), for higher quality checks, faster detections and less false positives. If you're already using WAC, you can simply add Themis, and WAC will automatically disable checks which are already covered by Themis (this behaviour can be disabled by adding "themis-ignore: true" to the config file).



This plugin only works on 1.13.X, 1.14.X, 1.15.X and 1.16.X. If the plugin doesn't work on your server, or if there's another problem, instead of just leaving a bad review please message me on Spigot or on Discord, so that I can help you and fix it!

Also note that WAC depends on ProtocolLib, you need to have it installed on your server!





Wither Anti Cheat, short WitherAC or WAC is a relatively new Anti Cheat. Although I'd say it's at a point where it can be used on production servers, be aware that false positives and other bugs are to be expected. However I'm regularly releasing updates with new features and fixes for bugs and false positives, and if you have any problems I'll be happy to help you out if you message me on Spigot or Discord (I'll usually respond faster on Discord).

Spigot, Paper and Tuinity are supported!

BungeeCord isn't directly supported, however @magefire9668 created an addon which uses WAC's API to distribute notifications accross server networks, you can find it here: https://www.spigotmc.org/resources/addon-witherac-bungee-link.76542/

GitHub link: https://github.com/Olexorus/WitherAC (not the full source code, but issue tracker, default config files and API code)

Discord link: https://discord.gg/2tzKFDJ2wW

I really recommend you to join the Discord if you use WitherAC. You also don't need to download anything, and you don't need to create an account, you can just open Discord in your browser.

If you find any bugs or bypasses please report them to me. I also take feature requests. If you want to become a tester, message me on Spigot or on Discord, all help is welcome!

• Active development: WAC is getting updated regularly, sometimes multiple times per week. If you find a bug, bypass or a false positive, I will try to fix it as soon as possible.
• Wide variety of checks: WAC has checks against many kinds of hacks, like movement related (e.g. Fly, Speed), combat related (e.g. Killaura, Reach) or others (e.g. Blink, Timer), you can check out the list below. The range of hacks which are blocked is also constantly expanded to combat new hacks.
• Simple config: WAC allows you to configure which checks should run, if and when staff should be notified about hackers, if and when hacks should be blocked, and much more. However, in contrast to many other AntiCheats, it doesn't give you a ton of confusing options about the individual checks. The reason for this is that, in my opinion, those configuration options are mostly useless. If there is a problem with a check it shouldn't be fixed by changing the config, because that usually isn't a real fix but just a workaround, instead the problem should be reported and the code should be adjusted so that the problem doesn't happen anymore.
  
• Easy to use: You don't need to spend hours configuring WAC before you can actually use it. While there is a configuration file, you don't need to touch it, you can just install WAC onto your server and let it take care of the rest.
• Developer API: WAC offers an API which allows you to integrate it with your other plugins. You can read more about the API below.

• Angle
• BHop Speed
• Blink
• Boat Fly
  
• Climb (aka Spider)
• EntitySpeed
  
• Fly
• Jetpack
  
• KillAura
• NoFall
• Nuker
  
• OnGround Speed
  
• Ping Spoof
• Reach
• Step
  
• Timer
• Vanilla Speed
• Water Walk (aka Jesus)

Note that this list is not complete. Some checks can catch hacks they weren't even designed for (for example Jetpack hacks are blocked by the Fly check even though I didn't add any special code for it, simply because of how similar Fly and Jetpack hacks behave). Also the same hack can have many different names in different hack clients, so even if a hack is not on this list, there's a decent chance it's blocked anyways.





Can you add support for version X?
