The Sulfur Exploit Will END Minecraft Servers

Summary

The video explains how an accidental discovery turned Minecraft’s sulfur cube into a potential server-crashing weapon. Griefer EZEno found the exploit while experimenting with the mob introduced in the Chaos Cubed update. Sulfur cubes can absorb blocks and take on their properties, and can normally be handled with shears or buckets.

How the Exploit Works

• A sulfur cube absorbs TNT.
• EZEno used packet manipulation to make the game register shearing and igniting the cube at the same time, causing its data to glitch.
• The cube became stuck in a permanently “primed” state. It could not be killed or collected in a bucket, but it could still absorb blocks.
• Giving it magma properties made it harmful to touch as well as invincible. The video describes these as hybrid sulfur cubes.

Griefing Tactics and Impact

EZEno’s group created large numbers of cubes by repeatedly splitting name-tagged ones, which prevented them from despawning. They transported the cubes in buckets and shulker boxes, then released them in busy areas of 6b6t.

The hybrids threatened players who touched them, while large numbers caused severe lag and eventually put the server into a crash loop. The group also stacked 3,000 invincible cubes in one spot to create a “gigacube,” which could sharply reduce nearby players’ frame rates and further burden the server.

What Players and Servers Can Do

The video says regular players have no practical way to stop the exploit: removing one group of cubes would not prevent griefers from creating another elsewhere. Admin intervention is presented as the only effective way to remove the cubes.

2b2t had not yet been affected at the time described because it was one update behind and did not have sulfur cubes. The video warns that the exploit could become a problem once the mob is added.
