opensquat 2.2

The openSquat is a tool for detecting phishing domains and domain squatting.

openSquat

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

As an opensource project, everyone's welcome to contribute.

Demo / Forks

• Phishy Domains for a simple web version of the openSquat.
• openSquat Bot for a simple Telegram bot.
• RapidAPI to integrate your application with openSquat using REST API.

Note: The forks do not contain all the 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

:warning: when updating: especially for a major release, re-run the pip install to check for new dependencies.

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 

Automations & Integrations

You can set up openSquat to run automatically using a task scheduler (such as crontab for Linux) to generate a new list of results daily.

We update our feeds with a fresh new list of domains every day around 7.30 am (UTC+0 / GMT+0)

# Crontab example - run openSquat every day at 8 am
# In this example, the results are saved to a JSON file format
0 8 * * * /home/john/opensquat/opensquat.py -k keywords.txt -o results.json -t json

You can use this output file to feed your SIEM, SOAR, or other tools that support importing from TXT/JSON/CSV formats.

Alternatively, currently in a Beta preview you can integrate using REST APIs, your application with RapidAPI

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: google+login) - Thanks to Steff T.
• Enhanced documentation

Feature Request
