Hello all, A hacker has been targeting my prison server. Whenever he enters, he magically seems to have the * permission. Whenever I check his ip, it is either "192.168.somthing" or "0.0.Something" I have banned many of his accounts, but every time he comes back with a new one it magically gets the * permission. I have looked through the logs, and no commands are issued by anyone to give him all permissions. He logs on an account for the first time, and just starts executing commands. Any ideas on how to stop him?
