Server hacked and redirecting

No support by the author.

Our server has recently been hacked, and when loading the forum index page it redirects to some silly page. i've checked for any code in the forum files that could redirect the forum, but there is none there. I've searched the vbulletin database and I couldn't find anything there either.

How do most hackers redirect pages once hacked? Do they edit the apache config files or something? How bad could the security breach be? Most important, what exploit might they have used?

Running fedora core 4
Plesk 8.01
Vbulletin 3.54

thanks for any kind of hints or answers.

Unfortunately a good amount of the hackers seem to come from Turkey. When I ran a php site we always blocked Turkey ips cause there known for tryin this stuff. It is up to you if you want to use it or not.

just add the following to your .htaccess file:

Code:
deny from 62.29.0.0/17
deny from 62.56.128.0/22

This is NOT going to stop a hacker, even from turkey. It will slow them down a bit.
Why do you do that ? There are hackers all around the world and you only belame Turkish people. That is nonsense. Anyway it is your choice not to let Turkish people to your board.

did u fix the problem? I recently had the SAME problem on my site...THREE times...i had one on friday, once on saturday morning, and now today, this morning. Luckily for me my mods call me once it happens, so I just fix it...

but basically for me, someone signed up on my forum and posted a thread with a title similar to this: >"">>>><meta http-equiv......

and it would basically take your homepage and redirect it to some other site. I would just delete the thread and it would fix the problem, however, that is just a short-term fix.

I censored some of the words for the redirect as well...try censoring "meta" or "http-equiv" and see if it fixes the problem so you can find the thread.

Also, try disabling your plugins/hacks one by one and see if it removes the redirecting. If u disable a hack and it doens't redirect, then u know that plugin/hack has a vulnerability and shoudlnt' be used unless u find the problem.

let me know if u find any other fixes...both u and I sound like we are getting the same problem...oh, and for the record, usually topxstats AND cyb avanced forumhome statistics BOTH have this problem

i am using 3.0.7
i do have this if ($_POST['do'] == 'postthread')

but the rest r like this

Code:
globalize($_POST, array('posthash' => STR_NOHTML, 'poststarttime' => STR_NOHTML));

	if (isset($_POST['WYSIWYG_HTML']))
nothing like 'subject'

please show me a way to fix this

i have the top 5x stat on my forum
