DDoS using Iframe. How to block their referer ?

[NgocChinh]

Hi,

They are including my pages inside iFrames on their site (rank on top 100)
I received millions request per hour and i can't access to my site because it very slow. it can chew up a lot of bandwidth and CPU cycles. I don't know how to block their referer.
Example:

My domain is : [url]www.ngocchinh.com[/url]
Their domain is: [url]www.attacker1.com[/url] and [url]www.attacker2.com[/url]

I have using .htaccess file to block, what' i wrong ?

RewriteEngine on
# Options +FollowSymlinks
RewriteCond %{HTTP_REFERER} attacker1\.com [NC,OR]
RewriteCond %{HTTP_REFERER} attacker2\.com
RewriteRule .* - [F]

So, what i can do to block their referer ? please show me how to do it !
Thanks

Do you use CSF? http://www.configserver.com/cp/csf.html
If not you might want to, that should help.

You might also want to do some homework on referral spam. Not exactly what you're having problems with but might be helpful.
