Substorm is a powerful and efficient tool designed to generate massive permutations of subdomains based on user-defined patterns. Whether you're conducting penetration testing, recon exercises, or looking to expand your DNS mapping, Substorm streamlines the process by creating exhaustive subdomain lists tailored to your needs.
-
Pattern-Based Subdomain Generation:
Generate subdomains using customizable patterns, such as{{sub}}.{{word}}.{{domain}}or{{region}}-{{sub}}-{{word}}.{{domain}}. -
Domain-Specific Expansion:
Dynamically generate subdomains for each domain listed in a given file, ensuring targeted fuzzing. -
Wordlist Integration:
Supports custom wordlists for words, numbers, and regions to create meaningful subdomains. -
Batch Processing:
Handles large-scale subdomain generation efficiently with batch-saving functionality. -
Duplicate Elimination:
Ensures no redundant entries in the generated output. -
Output Shuffling:
Produces randomized outputs to prevent predictable patterns. -
High Performance:
Optimized for speed and scalability, capable of handling massive lists effortlessly.
-
Bug Bounty Recon:
Expand your scope by discovering hidden subdomains missed by traditional scanners. -
Security Testing:
Identify potential entry points or misconfigurations in DNS setups. -
DNS Analysis:
Generate and test DNS permutations for large-scale environments. -
Data Enrichment:
Create domain variations for intelligence gathering and marketing.
-
Clone the repository:
git clone https://git 6D90 hub.com/yourusername/Substorm.git cd Substorm -
Install dependencies (Python 3.7+ required):
pip install -r requirements.txt
-
Run the tool:
python3 Substorm.py
-
Provide a List of Domains:
Input your target domains in thefiltered_subdomains.txtfile. The tool will process each domain from the list. -
Custom Wordlists:
Supply wordlists (word.txt,number.txt,region.txt) to the tool for generating subdomains based on patterns. -
Define Subdomain Generation Patterns:
Customize the patterns in the configuration file to generate subdomains in various formats (e.g.,{{word}}-{{sub}}.{{domain}}). -
Subdomain Generation:
The tool applies the patterns, generates subdomains for each domain, and saves them in batches for easy access. -
Output:
The tool creates organized output files for your subdomain lists, including sanitized, filtered, and batch files.
For the input domain: api.example.com, Substorm can generate subdomains like:
prod-api.example.com
api-prod.example.com
us-east.api.example.com
api123.example.com
test.api.example.com
You can customize the following settings in the script:
-
Domains File:
filtered_subdomains.txt– List of domains you wish to target. -
Wordlists:
word.txt,number.txt,region.txt– Custom lists to generate subdomains based on words, numbers, and regions. -
Patterns:
Modify thepatternsarray to use different permutations for subdomain generation.

### Explanation:
1. I ensured that the lines are wrapped properly, breaking long lines into smaller ones for better readability.
2. The code blocks and commands are indented correctly to maintain clarity in the `README.md` file.
This should now display properly in GitHub and other markdown renderers. Feel free to tweak it further if needed!
