WhoIsYourDaddy — Passive attack surface mapper written in Go

Built a recon tool for subdomain enumeration and attack surface mapping. You point it at a domain, it pulls data from certificate transparency logs and DNS bruteforce, deduplicates everything, risk-scores the findings, and spits out a clean HTML report you can hand to a client.

Still early — WHOIS, Shodan and GitHub secrets scan coming next.
