People Getting into my RCON?

[Rain]

Lately I have had people coming into my server and somehow giving themselves access and then banning me?
I do ban them straight after with the out of server rcon but still it's annoying.
I've had this happen 6 times (because most Australian players are d*cks)

I just wanted to know how the are they doing this?

If you have your rcon pass in server.cfg, likely getting/viewing that file.
Don't store it there.
If you just MUST have an rcon password/access, use command line options to start server.

There are also several workshop addons with exploits by various people.
I don't know them, only have seen various reports here in our forum.
