Sudomy - Subdomain Enumeration & Analysis

Sudomy is a subdomain enumeration tool, created using a bash script, to analyze domains and collect subdomains in fast and comprehensive way.

Features

For recent time, Sudomy has these 9 features:

Easy, light, fast and powerful. Bash script is available by default in almost all Linux distributions. By using bash script multiprocessing feature, all processors will be utilized optimally.
Subdomain enumeration process can be achieved by using active method or passive method
- Active Method
  - Sudomy utilize Gobuster tools because of its highspeed performance in carrying out DNS Subdomain Bruteforce attack (wildcard support). The wordlist that is used comes from combined SecList (Discover/DNS) lists which contains around 3 million entries
- Passive Method
  - By selecting the third-party sites, the enumeration process can be optimized. More results will be obtained with less time required. Sudomy can collect data from these well-curated 16 third-party sites:
```
  https://dnsdumpster.com
  https://web.archive.org
  https://shodan.io
  https://virustotal.com
  https://crt.sh
  https://www.binaryedge.io
  https://securitytrails.com
  https://sslmate.com/certspotter
  https://censys.io
  https://threatminer.org
  http://dns.bufferover.run
  https://hackertarget.com
  https://www.entrust.com/ct-search/
  https://www.threatcrowd.org
  https://riddler.io
  https://findsubdomains.com
```
Test the list of collected subdomains and probe for working http or https servers. This feature uses a third-party tool, httprobe.
Subdomain availability test based on Ping Sweep and/or by getting HTTP status code.
The ability to detect virtualhost (several subdomains which resolve to single IP Address). Sudomy will resolve the collected subdomains to IP addresses, then classify them if several subdomains resolve to single IP address. This feature will be very useful for the next penetration testing/bug bounty process. For instance, in port scanning, single IP address won’t be scanned repeatedly
Performed port scanning from collected subdomains/virtualhosts IP Addresses
Testing Subdomain TakeOver attack
Taking Screenshotsof subdomains
Report output in HTML or CSV format

How Sudomy Works
Sudomy is using cURL library in order to get the HTTP Response Body from third-party sites to then execute the regular expression to get subdomains. This process fully leverages multi processors, more subdomains will be collected with less time consumption.

Download Sudomy From Github

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

# Go into the repository
sudomy --help

Running in a Docker Container

# Pull an image from DockerHub
docker pull screetsec/sudomy:v1.1.0

# 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" -it --rm screetsec/sudomy:v1.1.0 [argument]

Post Installation
API Key is needed before querying on third-party sites, such as Shodan, Censys, SecurityTrails, Virustotal, and BinaryEdge.

The API key setting can be done in sudomy.api file.
