Layer 4 Amplification using Players as Attack Vectors (secret to realms crashing)

[Kushala Daora]

This one was quite a nice find. Basically, whenever you send a text packet, the server processes each byte in the packet, then sends it out to each player, regardless if they have their star requirement up. (can't say the same about ignoring, since that is server side)

Here is a video demonstrating.


Basically, have tons of bots spam the text packet over and over, then finish off the server with tons of spellbombs. (The server processes 20 ServerShoot packets with each spellbomb, so 100 spellbombs x 20 = 2000 packets to process in less than a second...)

Amazons DDoS protection kicks in after a few crashes and renders the spam useless, meaning it gets auto patched.

This was the secret to realms crashing, the longer the server was alive and processing other players' text packets, the higher chance of a crash. This is why fuller realms were more likely to crash.

me and @einaras had fun while it lasted, soon all the servers will auto patch this, which means rip oryx dupe

Seems like it only worked for a day. Duped quite a bit but got bored. Next day I tried and it was not working anymore. waited few weeks. tried again. Made eun2 lag so it killed 10 players at once and tiles loading every 2 seconds yet oryx shake was quicker than ever. We even went as hard as making 100 huntresses. Those caused lag too, still no luck at crashing.

rip oryx dupe

As long as the server rolls chars back, there is always going to be a way..
Or did I missunderstand this post?

òryx dupe =/= rollback.

Oryx dupe is when server crashes when players go to oryx and this cause rollback. Other things can cause rollback too so rip oryx duping, not rip duping.

The oryx crash happens cuz the server has had enough bullshit and kills itself...

the best way to say "not equals" is <>

Well I already knew via Einaras but I liked the addition.

Also allowing others to control it was a good idea

It's good to get others banned.

Evil.

grats, you ddos'd amazon

And since others could control it, he didnt even have to do anything, he could just sit and others could run the commands for him.

Considering the way it was done, you could say every player is guilty of that.

Just like the fame train medusa specials
