How do you find the list of server groups?

[Nova]

Hi,
Some guy hacked/managed to get access into my server and changed the adverts to something I won't post on here. I managed to find the file in garrysmod/data/ulx or something and removed it from the list but when I try and use rcon/console to make myself superadmin, I have no permissions. My guess is that he's changed all the ranks to have no permissions. (Example when I change myself to superadmin using "rcon ulx adduser Nova superadmin", it says "(Someone) added You to superadmin." but I still have user ranks.
How can I find the file which lists the ranks and the permissions, so I can fix this?

Thanks so much,
Nova.

Oh and also server ip if you need it is 178.33.135.116:27015

garrysmod/data/ulib/groups.txt is the file that contains groups and the permission for the groups.
However, it's highly discouraged to edit this manually. Instead, if you'd like everything reset to default, run this command in the server console: ulx resettodefaults

Hello there,
also make sure to set your rcon password via. the command-line instead of the server.cfg, as there is an exploit to read server files. (If you really have to use rcon at all, that is.)
