Minecraft’s Most DANGEROUS Glitch - Hidden For 8 Years...

I literally got banned from hypixel making this, so you guys better subscribe :) Join my discord - discord.gg/WGc9UNM EDIT: So after releasing the video, I got in contact with individuals in the community who know far more about the specifics of the game, its code and packets. They told me that looking into the code, the item transfer exploit seems to only work if you have creative mode on the receiving server. A bit unfortunate, but that was the point of me making the video. As I mentioned I didn't know enough about the game to understand the mechanics behind the bug. Still a cool bug worth making a video about though :)

Multiverse Of Madness

Hey, I'm the developer of LabyMod and I guess this is happening because of LabyMod's "Fast World Loading" optimization. It speeds up the loading screen when switching between worlds or respawning. It's kind of strange that there is such a lag when joining a server. Usually you have to add specific start-parameters in the launcher to achieve the same result.

And thus a month's worth of content was spawned by this one video.

you: oh nah its fine minecraft protects it, spoke: SO I OPENED UP A WORMHOLE

This is crazy and game breaking, congrats on bringing this obscure bug back to the spotlight, I'm sure any technical youtubers that hear of this will get cracking. And as you said, mojang had 8 years to fix this, don't blame yourself for learning more about it and trying to replicate it.

this happened to me!! this was super scary as well, thought I broke the entire server. EDIT: I found this glitch while on my garbage wifi while using forge

It's great watching someone bring light to this, this happened to me last year, took a couple screenshots and instantly disconnected, scared of the consequences

Something I do notice about this is that it wouldn’t work so well on 2b2t (ironic) because of its queue system. Players are logged into a separate queue server to wait to be logged into 2b2t itself. This way, only players with priority queue would be able to potentially utilize the glitch, as priority queue bypasses the wait. Otherwise they’d just be connecting to the queue server.

surprisingly this has happened to me sooo many times for years, so the fact that finally somebody has released a public video on the matter kinda sucks since now people r aware of its capabilities even though i was able to pull this off multiple times whenever i wanted to since i knew how to perform this bug

This mod feels like something you’d read in a creepypasta. It’s so bizarre! Thinking about it, I think it happened to me once when I first tried logging into a parkour server and I fell under the map onto the regular survival map. It kinda freaked me out since I thought i broke something by joining using heavier shaders. I think my game crashed after that too? Idk it’s been like 6+ months since it happened

Bro, memories just hit. As soon as you explained the bug, i remembered, it actually started happening to me so many years back, i had a shitty pc with a shitty connection and for some reason sometimes i would enter singleplayer worlds that had the chat of some of my online servers, eventually it fixed itself but i never thought anything about it

This glitch is also known as the Worm Hole witch was patched in 1.19.2 but normally replicated by using the essentials mod instade

TheMisterEpic: * exploits a glitch that Mojang hasn't patched for 8 years * Hypixel: "you werent supposed to do that!"

I love how the last few years has led to so much research about Minecraft and it's culture. I don't think I would've ever found the connection to the bug report on Mojang or the Xumavoid video labeled as a different bug

The thing that happens, as I think, is that the game didn't check if you are already in a server when joining another one. That basically causes the two servers to send world info to your client at the same time, so you constantly switch between the servers.

I experienced something similar all the way back in 2013; the only similar occurance though was that the chat from some random multiplayer server was flooding into my singleplayer world. Quite disturbing ngl

As a programmer, I don’t expect this bug to do anything that you can’t already do with modifying packets that your client sends (which is what most cheats in cheat clients are about) There simply is nothing special about this from the server’s perspective as it’s just a client sending random junk packets. The servers aren’t connected to each other, it’s just confusing the client and sending weird stuff

I've used this bug to do an all achievement speedrun in 1 frame a many years ago. For the glitch you just need to hover over a server, double tap enter, cancel, and quickly join a new world before you get connected to the first one.

You singlehandedly ended Lifesteal Season 4 Good Job!
