Sudomy is a subdomain enumeration tool, created using a bash script, to analyze domains and collect subdomains in fast and comprehensive way.
- 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 good 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 20 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 https://rapiddns.io/ https://otx.alienvault.com/ https://index.commoncrawl.org/ https://urlscan.io/

- 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 Screenshots of subdomains
- Identify technologies on websites
- Detection urls, ports, title, content-length, status-code, response-body probbing.
- Smart auto fallback from https to http as default.
- Data Collecting/Scraping open port from 3rd party (Default::Shodan), For right now just using Shodan [Future::Censys,Zoomeye]. More efficient and effective to collecting port from list ip on target [[ Subdomain > IP Resolver > Crawling > ASN & Open Port ]]
- Collecting Juicy URL & Extract URL Parameter ( Resource Default::WebArchive, CommonCrawl, UrlScanIO)
- Define path for outputfile (specify an output file when completed)
- Report output in HTML & CSV format
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.

Asciinema :
Sudomy is currently extended with the following tools. Instructions on how to install & use the application are linked below.
# Clone this repository
git clone --recursive https://github.com/screetsec/Sudomy.git$ pip install -r requirements.txt
Sudomy requires jq 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
npm i -g wappalyzer
# Mac
brew cask install phantomjs
brew install jq nmap npm
npm i -g wappalyzer# Pull an image from DockerHub
docker pull screetsec/sudomy:v1.1.6-dev
# 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:v1.1.6-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" -it --rm screetsec/sudomy:v1.1.6-dev [argument]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.
