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
• Bit squatting
• IDN homograph attacks
• Doppen ganger 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

How to Install

git clone https://github.com/atenreiro/opensquat
