weird user maybe a hacker

[dtv100]

this morning around 5am i went to who is online and i saw someone using one of my test account on our board and where his ip should be only say server2 then i click on resolve ip and i get 127.0.0.1 i delete the test account and he was trying to login using different admin names from forum leader list .Then I make all admins regular users just to be safe .

this for me is the first time i get someone with a ip like that because 127.0.0.1 should be local host .or I wrong?

any idea where i should look first ?

Re-upload all the default vBulletin files to be on the safe side.

that IP is simple to use... someone with a website hosted on the same server as you are, using a shelled page... automated login via localhost access... basic, first thing a newbie hacker would do to trick a forum from phpBB...

Well, since there aren't any currently known security issues with vBulletin, as long as your passwords are secure and relatively complex and you follow the basic security tips given out on the official site this user shouldn't succeed...

Not necessarily. The bad guys always find the exploits first... For all you know, there could be an exploit in the new vBulletin, just not yet known

Well if they were trying something tried on phpBB boards, then trying said technique on a vBulletin powered board, despite vBulletin being coded completely differently other than using PHP and MYSQL would not exactly make me think said 'hacker' was too competent.

That and I doubt Jelsoft would leave yet another security problem in vBulletin that somehow went undetected for months despite many great coders having used the software and probably would have reported any security problems they found...

is there any way I could ban using that ip I mean 127.0.0.1 with out any side effect to my board?

Unless other users use that IP, no.

I never said there is a security issue. I said 'there' could be

As I've said, exploits are always found by the bad guys first. Not every security issue is that noticeable, even with quality coders using vBulletin.

OK today he finally got a hold of my user account since he can only log as a user but cant can to control panel since we have a second password to it .
also he did same thing in our second site .
