## Title:       domainhunter.py
## Author:      Joe Vest and Andrew Chiles
## Description: Checks expired domains, bluecoat categorization, and Archive.org history to determine 
##              good candidates for phishing and C2 domain names

# To-do:
# Add reputation categorizations to identify desireable vs undesireable domains
# Code cleanup/optimization
# Add Authenticated "Members-Only" option to download CSV/txt (https://member.expireddomains.net/domains/expiredcom/)
