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 Symantec Site Review (BlueCoat), IBM X-Force, and Cisco Talos. The primary tool output is a timestamped HTML table style report.
See CHANGELOG for history of updates and release notes!
- Retrieve specified number of recently expired and deleted domains (.com, .net, .org) from ExpiredDomains.net
- Note: You will need credentials from expireddomains.net for full functionality
- Retrieve available domains based on keyword search from ExpiredDomains.net
- Perform reputation checks against the Symantec WebPulse Site Review (BlueCoat), IBM x-Force, and Cisco Talos
- Sort results by domain age (if known) and filter for reputation
- Text-based table and HTML report output with links to reputation sources and Archive.org entry

Build the image
docker build -t domainhunter . -
Run it with your arguments
docker run -it domainhunter [args]
usage: domainhunter.py [-h] [-a] [-k KEYWORD] [-c] [-f FILENAME] [--ocr]
[-r MAXRESULTS] [-s SINGLE] [-t {0,1,2,3,4,5}]
[-w MAXWIDTH] [-V]
Finds expired domains, domain categorization, and Archive.org history to determine good candidates for C2 and phishing domains
optional arguments:
-h, --help show this help message and exit
-a, --alexa Filter results to Alexa listings
-k KEYWORD, --keyword KEYWORD
Keyword used to refine search results
-c, --check Perform domain reputation checks
-f FILENAME, --filename FILENAME
Specify input file of line delimited domain names to
check
--ocr Perform OCR on CAPTCHAs when challenged
-r MAXRESULTS, --maxresults MAXRESULTS
Number of results to return when querying latest
expired/deleted domains
-s SINGLE, --single SINGLE
Performs detailed reputation checks against a single
domain name/IP.
-t {0,1,2,3,4,5}, --timing {0,1,2,3,4,5}
Modifies request timing to avoid CAPTCHAs. Slowest(0)
= 90-120 seconds, Default(3) = 10-20 seconds,
Fastest(5) = no delay
-w MAXWIDTH, --maxwidth MAXWIDTH
Width of text table
-V, --version show program's version number and exit
Examples:
./domainhunter.py -k apples -c --ocr -t5
./domainhunter.py --check --ocr -t3
./domainhunter.py --single mydomain.com
./domainhunter.py --keyword tech --check --ocr --timing 5 --alexa
./domaihunter.py --filename inputlist.txt --ocr --timing 5
Use defaults to check for most recent 100 domains and check reputation
python3 ./domainhunter.py
Search for 1000 most recently expired/deleted domains, but don't check reputation
python3 ./domainhunter.py -r 1000
Perform all reputation checks for a single domain
python3 ./domainhunter.py -s mydomain.com
