Recently, Within 2-3 Days, I’ve been having random users attempting to join my server (Whitelisted) These people are joining at random times, i don’t know who they are, I searched up a few names but didn’t find much, I did find reports of SanJackDo.

In what way is this an attack?

Hmmm, do you call this an attack? You prob new to this :smile:. I have seen tools that using the minecraft protocol to ping to servers. Run that in a botnet, and ehm your server will be down.

It happend to my server various times, somehow bungeecoord managed to keep the cpu load low. But the console was unreadable.

EDIT for title change:

If you registered your server on a server list, you don’t have to be suprised that people try to join xD.

You’re probably not under attack. No worries. :smile:

The most obvious cause of users attempting to log onto your server is likely the very thing you posted in your OP.

People see this, and attempt to join. With nothing more than an IP, they can’t know how to register on your whitelist, so they just attempt to join repeatedly.

Another cause would be you hosting your server through a common Minecraft server host. You get someone’s old IP, and users from that server attempt to join it expecting to find the old owner, and instead get you.
