Behindflare

This tool was created as a Proof of Concept to reveal the threats related to web service misconfiguration using CloudFlare as reverse proxy and WAF.

Problem

Most of CloudFlare users believe, that just setting up the reverse proxy which ensures security protection, will secure their back-end servers. This group of users are not aware that the attacker can find access to the back-end servers if he finds their IP addresses. There are plenty of passive and active techniques that can lead you to get the IP address of the Web App server.

Service

If you would like to protect your servers against this kind of attack you can contact us at Gonkar IT Security LTD
