Crash Exploit: Allows for crashing of Realms, and multiple sponsored and non-sponsored servers

Crash Exploit

By "noping" this opcode (part of the movement packet builder assembly), any server without server side teleport protection (realms, single player worlds open to friends, inpvp, and hive) will crash the current server or disconnect everyone in render distance within 10 - 20 seconds. Through minimal testing I have found that there must be one player in render distance for it to work. I have not confirmed this fully in all cases though. It is most effective on realms and single player worlds open to friends. Causing the realm to restart and single player worlds open to friends to disconnect all player but the host. It is hit or miss on the hive and inpvp, 30% of the time it works.

 

EDIT: On realms you do not need anyone else in render distance as shown in video below.

Here is an unlisted video of it working on 1.8  Video

This is a screenshot of the Minecraft 1.8 opcode it still works in Minecraft 1.8.1 though.

EDIT: Looked into it a little further and found that it has to do with the x and y coords. Also found out that the smart boys at Minecraft move the x and y in a double to increase performance. Cool beans
