GitSniff

GitSniff is an MIT licensed OSINT tool designed to extract emails from metadata on GitHub accounts and repos. I built this because all the other similar tools were too limited or broke years ago.

Features

• Find emails in github repo metadata.
• Find emails from GitHub's user event feed
• Outputs results as a table or JSON

Install

pip install gitsniff

Usage

# Scan a user.
gitsniff -u <username>

# Scan a single repo.
gitsniff -r <repo>

# Show full help pages.
gitsniff -h

The email, reginaldgillespie@protonmail.com, is my email. The rest are the emails of other users found in my repositories because they contributed to them using their real emails.

This project was inspired by similar, but more limited projects such as:

• GONZOsint/gitrecon - scans event feeds for information.
• chm0dx/gitSome - scans single repositories.
