DDOS & Flood Attack on vBulletin
 

Hello,

i got Flood attack on my site.. with bots. like 1500 bots just keep opening 1 thread and forum goes down.. i have paid $600 For DDOS Proxy Shield Protection .. and its Protect with 2GBPS Protection Level/ Attack Size .. and my forum again goes down i received e-mail from my DDOS proxy shield provider!!

Your forum is under a heavy mysql attack. Please investigate your script and remove the exploit to solve this problem. Yes, proxyshield can't protected the internal script attack like this. You need to find out which file is being used to attack the mysql

Kind regards,

Try disabling your modifications/plugins and see if this helps.
Note: To temporarily disable the plugin system, edit config.php and add this line right under <?php

Also, look at your access_logs (if you don't know where they ae, ask your host) to see if it is a particular script being targetted.
