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 reputation 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

Usage

Install Requirements

pip install -r requirements.txt
or
pip install requests texttable beautifulsoup4 lxml

List DomainHunter options

python ./domainhunter.py
usage: domainhunter.py [-h] [-q QUERY] [-c] [-r MAXRESULTS] [-w MAXWIDTH]

Checks expired domains, bluecoat categorization, and Archive.org history to
determine good candidates for C2 and phishing domains

optional arguments:
  -h, --help            show this help message and exit
  -q QUERY, --query QUERY
                        Optional keyword used to refine search results
  -c, --check         Perform slow reputation checks
  -r MAXRESULTS, --maxresults MAXRESULTS
                        Number of results to return when querying latest
                        expired/deleted domains (min. 100)

Use defaults to check for most recent 100 domains and check reputation

python ./domainhunter.py

Search for 1000 most recently expired/deleted domains, but don't check reputation against Bluecoat or IBM xForce

python ./domainhunter.py -r 1000 -n

Search for available domains with search term of "dog" and max results of 100

./domainhunter.py -q dog -r 100 -c
