CloudFail is a tactical reconnaissance tool designed to gather sufficient information about a target protected by Cloudflare in hopes of discovering the server's location.
Using Tor to obfuscate all requests, the tool now has three different attack stages:
⏺ DNS misconfiguration scanning using DNSDumpster.com
⏺ Crimeflare.com database scanning
⏺ Brute-force scanning of 2,897 subdomains
