AnarchyExploitFixes

Fix exploits on a Minecraft Anarchy Server

Requirements

• PacketEvents - This is for preventing packet exploits. Without it, the plugin will not enable.

Prebuilt jar

Go to releases, download the latest jar

If you wish to have a prebuilt BETA jar with the latest code, click Actions at the top of the page, click the latest build, and download the artifact.

Building from source

Commands

These commands can only be executed from console or by opped players.

• /aef reload - Reload the config
• /aef datavalue - (1.12 Relevant) Get the data value for the item you're holding to add it to the remove list
• /aef elytra - See who is flying on an elytra.
• /aef geared - See how many players have armor or are new.
• /aef lag - artificially lag the server for testing. Every time you run the command the server freezes for 1 second by default, add milliseconds to the end of the command for custom time.
• /aef version - Plugin version.

Notice

Please note that some exploits have already been patched by LPX AntiPacketExploit or Panilla, meaning they are most likely not included in AEF. I recommend using those alongside AEF to patch the majority of exploits.

Features

This list does not include all features, check the config for all features!

All features listed here can be disabled or enabled in the config.

• Prevent NoCom exploit. - Prevent the 'NoCom' coordinate exploit
• Prevent a new lag exploit where fireworks can bring tps down to single digits.
• Prevent BowBomb exploit. - Prevent an exploit where bows can instantly kill a player.
• Prevent Burrow hack - Where you step inside a block so crystals can't do any damage.
• Prevent BoatFly exploit - Prevent the Futureclient / Rusherhack BoatFly exploit.
• Prevent Book-ban - All characters still work! The size of each page is just limited to 255 bytes (customizable). This allows to fill the whole page with latin characters. Characters that use more bytes such as Chinese may be limited in length.
• Prevent unbreakable Packet elytra fly.
• Prevent PacketFly exploit.
• Prevent end gateway crash exploit. - https://www.youtube.com/watch?v=c5nVBQeYo-I
• Patch end portal dupe. - https://www.youtube.com/watch?v=n-fN6txZNgc
• Prevent Y256 dispenser crash exploit. - https://www.youtube.com/watch?v=XL17P87O6xA
• Anti-Illegal system:
  • Remove/revert illegal items: banned items, overstacked items, higher enchanted items, items with illegal datavalues, incompatible enchanted items (eg Silk Touch & Fortune on the same item), inapplicable enchanted items (unenchantables), Spawneggs and unbreakable items and all shulkers containing them.
  • Remove illegal blocks that have been placed in the world. Supports removal of non-natural spawners too!
• Limit speed of snowballs to prevent clientside lag.
• Limit crafting table autorecipe speed to prevent a lag exploit.
• Prevent all coordinate exploits related to teleporting by vanishing a player right before they are teleported.
• Prevent destroying end portal frames.
• Prevent multiple end dragons from being created.
• Prevent portal traps - Teleport a player back to the original portal if they're trapped for too long.
• Automatically fill in the bedrock floor/roof if the bedrock has been broken.
• Prevent players from going below the bedrock floor by teleporting them up. - Useful so people can't elytra fly below the world.
• Remove wither heads automatically to prevent lag. - Removes on chunk load, unload or after a customizable alive time
• Option to disable wither spawning at spawn. - Disabled by default.
• Prevent chunk ban exploit. - Checks how much of each block is in a chunk.
• Prevent chat spam. - Delay between messages, Max messages per a certain time, separate link delay, character limit, and more!
• Prevent god mode exploit. - Prevent most godmode exploits, please note, there could still be bypasses.
• Prevent invalid names. - Disallow login from players with invalid characters/too long of a name.
• Prevent command signs. - Prevent players from right-clicking signs that have been placed with a command attached. For example, from a backdoor.
• Limit falling blocks per chunk to prevent lag.
• Limit exp bottles per chunk to prevent lag.
• Prevent projectiles from going through portals, shooting projectiles through portals can get them stuck in the same place on the other side, once they are loaded the server can crash.
• Prevent too many vehicles (eg. minecarts, boats) in chunks.
• Prevent bed-traps. - Disabled by default. Teleports players back to original location when they have been standing in a portal for too long.
• Prevent nether roof access. - Disabled by default.
• Prevent placing blocks on nether roof
• Option to disable chests on donkeys. - This is unlike IllegalStack's, no items will drop if the chest is broken. Useful to prevent many dupe exploits, Disabled by default.
• Option to prevent donkeys from going through portals. - Useful to prevent many dupe exploits, disabled by default.
• Option to mask all kick messages. - Change every kick message to "You have lost connection to the server", or whichever you specify. Disabled by default.
• Option to enable first join message. - Disabled by default.
• Command whitelist - Useful for only allowing commands that you want to be allowed, so players can't find your plugins. Disabled by default.
• Elytra speed limits for old and new chunks, and bursting settings for when tps is high.
• Elytra action bar to show players the speed they are going and speed limit.
• Rate-limit levers - Disabled by default. Prevent lag by spamming levers.
• Options to disable certain game features at specific TPS. Redstone, Elytra, Explosions, Falling Blocks.
• Bedrock Filler - Option to automatically fill overworld bedrock floor, nether bedrock floor and nether bedrock ceiling.

Config options

Missing config options will now automatically add themselves with every update without the config resetting.
