Domain Hunter

Authors Joe Vest (@joevest) & Andrew Chiles (@andrewchiles)

Domain name selection is an important aspect of preparation for penetration tests and especially Red Team engagements. Commonly, domains that were used previously for benign purposes and were properly categorized can be purchased for only a few dollars. Such domains can allow a team to bypass reputation based web filters and network egress restrictions for phishing and C2 related tasks.

This Python based tool was written to quickly query the Expireddomains.net search engine for expired/available domains with a previous history of use. It then optionally queries for domain reptutation against services like BlueCoat and IBM X-Force. The primary tool output is a timestamped HTML table style report.

Features

• Retrieves specified number of recently expired and deleted domains (.com, .net, .org primarily)
• Retrieves available domains based on keyword search
• Performs reputation checks against the Blue Coat Site Review service
• Sorts results by domain age (if known)
• Text-based table and HTML report output with links to reputation sources and Archive.org entry
