Armour stand lag machines

CF

Armor stands can be used to create lag machines. This is done by placing huge amounts of armor stands and forcing them to move via water, pistons or other means.

Book Exploits

CF

Books are a common target for exploitation techniques, and have been used for all sorts of nasty things in the past including duplication exploits, crash exploits, and forcing servers to run out of memory while producing massive amounts of chunk data.

3

Collision Lag Machines

CF

This exploit is similar to the armor stand one, but instead of armor stands, it uses entities that can be pushed by other entities.

>= Paper

✅ Since 1.1.0

4

Command suggestion packet spam

CF

Some commands on the server might have a lot of logic involved with their command suggestions. This can be exploited by sending a lot of packets that request the server to send suggestions for the command.

>= Paper

✅ Since 1.1.0

5

Command spam

CF

While even spigot will protect you from this exploit, there's a slight oversight that will enable a single command to be usable to perform this one.

>= Spigot

✅ Since 1.1.0

6

Join spam

CF

Sometimes shear quantity of players joining the server can cause the server to lag out. This is especially true for bot attacks and moments after server restart.

>= Paper

✅ Since 1.1.0

7

Neighbor update lag machines

CF

Limiting the amount of consecutive neighbor updates before skipping additional ones.

>= CraftBukkit

✅ Since 1.1.0

8

Projectile suspension

CF

Projectiles can be suspended in bubble columns indefinitely. They can also be transported into unloaded chunks in mass. If anyone loads the chunk with amassed projectiles, server can crash due to loading too many things at once.

>= Paper

✅ Since 1.1.0

9

Recipe book spam

CF

Malicious players can use auto clicker or a mod to switch between recipe book recipes extremely quickly. This is pretty expensive operation for the server and can cause huge slowdowns.

>= Paper

✅ Since 1.1.0

10

Treasure search

CF

When new treasure map is generated, usually via cartographer villager or opening a chest with treasure map in it, the server searches for the treasure that map should lead to. This search is done in a way that in most cases causes a lot of chunks loading and possibly generating them. This search can halt the server for long enough that watchdog process kills it. It can also be triggered by feeding dolphins fish.
