Characteristics

  1. Incorrect DNS scan configuration using DNSDumpster.com.
  2. Scanning a database on Crimeflare.com.
  3. Bruteforce option that scans over 2500 subdomains.

Installation in Kali / Debian

First we need to install pip3 for python3 dependencies:

$ sudo apt-get install python3-pip

Next, we can perform dependency checks:

$ pip3 install -r requirements.txt

If this fails due to a lack of installation tools, run the following command:

sudo apt-get install python3-setuptools

Use

To perform a scan on a target run the command:

python3 cloudfail.py --target seo.com

To perform a scan on a target using Tor run the command:

service tor start

(or if you are using Windows or Mac install vidalia or just run the Tor browser)

  Mozilla Firefox Private Network prepares proxy servers

python3 cloudfail.py --target seo.com --tor

Make sure you are running the program with Python3 and not Python2.

Conditions
