Websploit Cloudflare Resolver module


In this tutorial we will be testing and using the Cloudflare resolver module in Websploit on Kali Linux. Cloudflare is a company that provides a content delivery network and distributed DNS (Domain Name Server) services, sitting between the visitor and the hosting provider of the Cloudflare user. This way Cloudflare is acting as a reverse proxy for websites and claims to protect, speed up, optimize and improve availability for a website. Cloudflare also provides advanced DDOS protection for a website, including those targeting UDP and ICMP protocols. Cloudflare claims to protect more than 2 million website at the time of writing. The Websploit Cloudflare Resolver module claims to resolve the original IP address of the server protected by Cloudflare.

Hackingtutorials.org is not using Cloudflare so it will display the webserver’s real IP address. I tried this module on a couple websites using Cloudflare and it returns the Cloudflare IP address mostly. This module does return the IP addresses for sub-domains and sometimes this gives you useful information and non Cloudflare IP addresses but this could also be done by a simple ping on subdomains.
