I block request in .htaccess and request result id 403 How can I prevent this attack? waf? cloudflare? I user cPanel + Litespeed

Answer 1

Controlled with the following Items:

first, add this code in index.php

<?php
if(!isset($_SERVER['HTTP_USER_AGENT'])){
exit();
}
if ($_SERVER['HTTP_USER_AGENT'] == "python-requests/2.25.1" || $_SERVER['HTTP_USER_AGENT'] == "a" || $_SERVER['HTTP_USER_AGENT'] == "\\"){
        exit();
}

next I block IPs with this command:

cat /var/log/apache2/domlogs/mydomain.com-ssl_log | awk '{print $1}' | sort | uniq -c |sort -n |  awk '{ if($1 > 10000) print $2 }' >> /etc/csf/csf.deny
