Do not worry, no personal files were stolen and the damage has been restored already. Nonetheless I felt like writing a statement to explain what has happened and what has been done to resolve it.
Apparently there was a problem with our firewall. A problem between the communication of Spigot and BungeeCord allowed an individual to slip in through the cracks and log in as me, UnlitedOwns.
You should understand that BungeeCord runs the Network, thus allowing you to say /glist and to switch to the different servers. Spigot runs the server itself, keeping track of what happens there and makes sure to store your files safely.
Now the breach was with the Spigot part of the server. The individual managed to get in to Skykits and log in as me. He then proceeded to grief parts of the server and give everyone permissions to everything. Staff was alarmed fairly quick and took care of the situation, the administration team took down the server and whitelisted it. The damage has been undone, as well - we make backups. No worries! Nothing of your stats is gone. It's as if nothing ever happened.
We inmediately put back up our firewall as soon as we found out that it may have been that what allowed the individual in to the server. We're also adding additional protection for staff members. Meaning, staff will have a two factor authentication before they can really do anything on the server.
After investigating the matter more this has not only happened to Ophion, but to other servers running BungeeCord as well. I will most likely create a post on PlanetMinecraft to address this serious matter to fellow server administrators.
We're also going through the logs of all the other servers and seeing if any of them have been breached.
Do not fear, the Ophion Staff Team is here.
