"Hackers" Entered Server

Not entirely sure where to put this, but two players have recently entered our server using the dynamic IP, and changed their username to those active during the breach to prevent them from joining. In the end they had griefed and blew up structures while spitting repetitive racial slurs. I have the copy of the log but I am worried that posting it here may give access to others to redo the same scheme. I'm only wondering if there's a way to report them in Aternos to prevent them from redoing this fiasco.

Ohh then that's okay, I've done all countermeasures I could do now to prevent uninvited guests. Thank you for the reply.

And yes it is a cracked server, just vanilla.

Ohh thank you for the suggestion! I'll greatly consider this!

Panos Ah it was, it was a good thing I setup a Google Drive backup account before it so it was easy to fix, was just really stressful that time.
