[Suspicious Activity] Registering of account "superadmin"

[Brain]

14:30 german time
I've been tinkering with the Teamspeak query script when this guy with AOL IP address entered the server. He didn't say anything nor did he react on what i said.
He left two times and returned as registered user with the name "moondog" (anonymous players can register). I looked him up in the control panel, however there was no moondog, but a new user "superadmin" registered at just about that time.
I guess he was trying to exploit an old flaw in the Teamspeak server or something. I've garbled the password for his "superadmin" account because i was afraid some bug in the server (2.0.19.40) would delete the real superadmin as well.

Is there reason to be concerned?

No, nothing to be worried (as far as we know :D).

superadmin and normal users are kept in a different lists, so it shouldn't matter whatever a users calls himself, unless Ralf explicitly checks on somebody with the string "superadmin" in his name, which is *uhm* veeeery unlikely :o). What I'm wondering is how a user got rid of a account though...you say he was registered as moondog and that loginname was not to be found in the list ? Now thats weird.

[SatanClaus]

was moondog his login-name or his nickname?

[Brain]

when he was unregistered he just had Guest1 as nickname, after registering his login-name superadmin his nickname was moondog

[Peter]

Oh right,

well then nothing is weird. I thought he had two loginnames (superadmin and moondog, and somehow managed to delete the "moondog" one.
