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
- 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.
Please check Phishy Domains for a simple version of the openSquat.

To Do / Roadmap
Integration with VirusTotal (VT) for subdomains validation
- Integratration with VirusTotal (VT) for malware detection
Use certificate transparency Homograph detectiondone Improve code quality from B to A grade (codacy) PEP8 compliance
- Add documentation
