Comprehensive subdomain discovery using certificate transparency logs (crt.sh), DNS brute force, and passive sources. The first step in any recon pipeline — you can't attack what you don't know exists. Subdomain enumeration consistently reveals staging environments, internal admin panels, API gateways, and forgotten WordPress installs that are softer targets than the production site.

# Passive: crt.sh
curl --max-time 30 --connect-timeout 10 -sk "https://crt.sh/?q=%25.$DOMAIN&output=json" | jq -r '.[].name_value' | sed 's/\*\.//g' | sort -u > crtsh.txt
# Passive: subfinder
subfinder -d "$DOMAIN" -silent > subfinder.txt
# Merge and deduplicate
cat crtsh.txt subfinder.txt | sort -u > all_subs.txt
# Probe live hosts
httpx -silent -l all_subs.txt -threads 50 -status-code -tech-detect -title -o alive.txt
| Source | Method | Coverage | Speed |
|---|---|---|---|
| crt.sh | Certificate transparency | Excellent (most certs) | Fast (1-5s) |
| subfinder | Passive APIs (VirusTotal, Shodan, DNSdumpster, etc.) | Very good | Fast (30-60s) |
| dnsx | Bulk DNS A/AAAA/CNAME resolution (100x faster than dig) | Good (uncovers non-HTTP) |
| Fast (10-30s) |
| httpx probe | Live HTTP/HTTPS check | Best for web attack surface | Fast (30-60s) |
