Sudomy is a subdomain enumeration tool to collect subdomains and analyzing domains performing advanced automated reconnaissance (framework). This tool can also be used for OSINT (Open-source intelligence) activities.

Features !

For recent time, Sudomy has these 20 features:

Comparison

Sudomy minimize more resources when use resources (Third-Party Sites) By evaluating and selecting the good third-party sites/resources, so the enumeration process can be optimized. The domain that is used in this comparison is tiket.com.

The following are the results of passive enumeration DNS testing of Sublist3r v1.1.0, Subfinder v2.4.5, and Sudomy v1.2.0.

<img width="935" alt="Untitled" src="https://user-images.githubusercontent.com/17976841/102053848-00990700-3e1b-11eb-9f48-9a82a8b3e64e.png">

In here subfinder is still classified as very fast for collecting subdomains by utilizing quite a lot of resources. Especially if the resources used have been optimized (?).

For compilation results and videos, you can check here:

When I have free time. Maybe In the future, sudomy will use golang too. If you want to contributes it's open to pull requests.

But it's shit! And your implementation sucks!

Installation

Sudomy is currently extended with the following tools. Instructions on how to install & use the application are linked below.

To Download Sudomy From Github

# Clone this repository
git clone --recursive https://github.com/screetsec/Sudomy.git

Dependencies

$ python3 -m pip install -r requirements.txt

Sudomy requires jq and GNU grep to run and parse. Information on how to download and install jq can be accessed here

# Linux
apt-get update
apt-get install jq nmap phantomjs npm chromium parallel
npm i -g wappalyzer wscat

# Mac
brew cask install phantomjs 
brew install jq nmap npm parallel grep
npm i -g wappalyzer wscat


# Note
All you would need is an installation of the latest Google Chrome or Chromium 
Set the PATH in rc file for GNU grep changes

Running in a Docker Container

# Pull an image from DockerHub
docker pull screetsec/sudomy:v1.2.1-dev

# Create output directory
mkdir output

# Run an image, you can run the image on custom directory but you must copy/download config sudomy.api on current directory
docker run -v "${PWD}/output:/usr/lib/sudomy/output" -v "${PWD}/sudomy.api:/usr/lib/sudomy/sudomy.api" -t --rm screetsec/sudomy:v1.1.9-dev [argument]

# or define API variable when executed an image.

docker run -v "${PWD}/output:/usr/lib/sudomy/output" -e "SHODAN_API=xxxx" -e "VIRUSTOTAL=xxxx" -t --rm screetsec/sudomy:v1.1.9-dev [argument]
