Is my forum hacked?
 

HI!!

I have a vbulleting 4.2 in apache2 server.
Since yesterday, I've found that my server is stop every time for mysql. Investigation logs, I find querys like this:

SELECT * FORM VBULL.FORUMUSER where username = 'pepe222' = sleep (4) = 00;

mysql paralyzing.

Is there such a query in the forum or are hacking me?

(sorry for my poor english)

Best

Are you running the latest version with all the patches? Do you have any modifications? Try disabling them and see if the problem stops.
