Using CSF to block IPs sending GET/POST request multiple times

Hi,

Can I use CSF to block IPs involved in this sort of attacks -

IPs are changing and continuously sending out requests to the account, finally this causes resource limit exceed error on website.

What settings should I change in CSF to stop these sort of attacks.

Thanks

Re: Using CSF to block IPs sending GET/POST request multiple times

Post by ohgoodiee »

I know this post is a year old, but maybe someone can find this useful.

Create a htaccess file, put the following in there and that will block the POST, etc

RewriteEngine On

RewriteCond %{REQUEST_METHOD} ^(CONNECT|HEAD|TRACE|DELETE|TRACK|DEBUG|MOVE|PUT) [NC]
RewriteRule ^(.*)$ http://yandex.com/ [R=302,L]
#RewriteRule ^(.*)$ - [F,L]

RewriteCond %{HTTP_USER_AGENT} ^$ [OR]
RewriteCond %{HTTP_USER_AGENT} ^.*(<|>|'|%0A|%0D|%27|%3C|%3E|%00).* [NC,OR]
RewriteCond %{HTTP_USER_AGENT} ^.*(Java|htmlparser|python|zend|zgrab|raynette|lwp|nutch|virusdie|lynx|Dataprovider).* [NC,OR]
RewriteCond %{HTTP_USER_AGENT} ^.*(winhttp|libwww\-perl|curl|wget|harvest|scan|grab|extract|HeadlessChrome).* [NC]
RewriteRule ^(.*)$ http://yandex.com/ [R=302,L]

RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http(s)?://(www\.)?your-domain-name-here [NC]
RewriteRule \.(jpg|jpeg|gif|png|bmp|exe|swf|svg|css|txt|js|scss|pdf)$ ? [F,L]

This can also be added to the Apache conf file.
