AntiSquat leverages AI techniques such as natural language processing (NLP), large language models (ChatGPT) and more to empower detection of typosquatting and phishing domains.

How to use

• Clone the project via git clone https://github.com/redhuntlabs/antisquat.
• Install all dependencies by typing pip install -r requirements.txt.
• Get a ChatGPT API key at https://platform.openai.com/account/api-keys
• Create a file named .openai-key and paste your chatgpt api key in there.
• (Optional) Visit https://developer.godaddy.com/keys and grab a GoDaddy API key. Create a file named .godaddy-key and paste your godaddy api key in there.
• Create a file named ‘domains.txt’. Type in a line-separated list of domains you’d like to scan.
• (Optional) Create a file named blacklist.txt. Type in a line-separated list of domains you’d like to ignore. Regular expressions are supported.
• Run antisquat using python3.8 antisquat.py domains.txt

Examples:

Let’s say you’d like to run antisquat on "flipkart.com".

Create a file named "domains.txt", then type in flipkart.com. Then run python3.8 antisquat.py domains.txt.

AntiSquat generates several permutations of the domain, iterates through them one-by-one and tries extracting all contact information from the page.

Test case:

A test case for amazon.com is attached. To run it without any api keys, simply run python3.8 test.py

Here, the tool appears to have captured a test phishing site for amazon.com. Similar domains that may be available for sale can be captured in this way and any contact information from the site may be extracted.
