What is openSquat

openSquat is an opensource Intelligence (OSINT) security tool to identify cyber squatting threats to specific companies or domains, such as:

• Phishing campaigns
• Domain squatting
• Typo squatting
• Bitsquatting
• IDN homograph attacks
• Doppenganger domains
• Other brand/domain related scams

It does support some key features such as:

• Automatic newly registered domain updating (once a day)
• Levenshtein distance to calculate word similarity
• Fetches active and known phishing domains (Phishing Database project)
• IDN homograph attack detection
• Integration with VirusTotal
• Integration with Quad9 DNS service
• Use different levels of confidence threshold to fine tune
• Save output into different formats (txt, JSON and CSV)
• Can be integrated with other threat intelligence tools and DNS sinkholes

This is an opensource project so everyone's welcomed to contribute.

Demo / Forks

• Phishy Domains for a simple web version of the openSquat.
• openSquat Bot for a simple Telegram bot.

Note: Both forks do not contain all openSquat features.

How to Install

    git clone https://github.com/atenreiro/opensquat
    pip install -r requirements.txt

Make sure you have Python 3.6+ and pip3 in your environment

How to Update

To update your current version, just type the following commands inside the openSquat directory:

    git pull
    pip install -r requirements.txt

The "pip install" is just to make sure no new libs were added with the new upgrade.

Usage Examples

Edit the "keywords.txt" with your customised keywords to hunt.

    # Lazy run with default options
    python opensquat.py

    # for all the options
    python opensquat.py -h
    
    # Search for generic terms used in phishing campaigns (can lead to false positives)
    python opensquat.py -k generic.txt

    # With DNS validation (quad9)
    python opensquat.py --dns
    
    # Subdomain search
    python opensquat.py --subdomains
    
    # Check for domains with open ports 80/443
    python opensquat.py --portcheck

    # With Phishing validation (Phishing Database)
    python opensquat.py --phishing phish_results.txt

    # Save output as JSON
    python opensquat.py -o example.json -t json

    # Save output as CSV
    python opensquat.py -o example.csv -t csv

    # Conduct a certificate transparency (ct) hunt
    python opensquat.py --ct

    # Period search - registrations from the last month (default: day)
    python opensquat.py -p month

    # Tweak confidence level. The lower values bring more false positives
    # (0: very high, 1: high (default), 2: medium, 3: low, 4: very low
    python opensquat.py -c 2

    # All validations options
    python opensquat.py --phishing phishing_domains.txt --dns --ct --subdomains --portcheck 

To Do / Roadmap

• Integration with VirusTotal (VT) for subdomains validation
• Integratration with VirusTotal (VT) for malware detection
• Use certificate transparency
• Homograph detection done
• Improve code quality from B to A grade (codacy)
• PEP8 compliance
• AND logical condition for keywords search (e.g: goole+login) - Thanks to Steff T.
• Add documentation
