N U K E // recon & attack surface mapper
-----------------------------------------
Bash-based passive reconnaissance + attack surface mapping script using only public APIs + stock Linux tools (curl, dig, openssl, nmap, python3).
All output goes to a single .txt file: nuke_<domain>.txt.
No dependency on subfinder, ffuf, gobuster, subjs, getJS, jshunter, or js_snitch.
| # | Module | Source / Technique |
|---|---|---|
| 1 | Subdomains via CT | crt.sh |
| 2 | Subdomains via alternate CT | crt.name |
| 3 | Subdomains (optional, requires key) | SecurityTrails API |
| 4 | Subdomains + URLs + IPs | OTX AlienVault |
| 5 | Domains + IPs + ASN/Server | urlscan.io |
| 6 | Subdomains + siblings + IPs (requires key) | VirusTotal v2 |
| 7 | Consolidated subdomains | Union + dedupe across all sources |
| 8 | DNS (TXT/SPF, A, AAAA, NS, MX, SOA + AXFR) | dns.google (DoH) + dig/host — equivalent to dnsrecon -d |
| 9 | WHOIS | RDAP via rdap.org |
| 10 | IPs / Reverse DNS / RDAP-IP / HTTP status | dns.google PTR + rdap.org/ip + curl -I |
| 11 | Favicon hash (Shodan hunting) + IP SSL verification | Local Shodan-standard murmur3 (http.favicon.hash) + openssl + nmap --script ssl-cert |
| 12 | JS files + extracted endpoints | <script src> parsing + path/URL regex (replaces subjs/getJS/jshunter) |
| 13 | Historical URLs | Wayback Machine CDX |
| 14 | Origin IP discovery (CDN/WAF bypass) | Correlates DNS + OTX + urlscan + VT + SPF + Shodan, filters via RDAP org + Host: header test |
| 15 | Built-in dirscan | High-signal curated wordlist, parallel (no ffuf/gobuster needed) |

Manual verification of an origin-IP candidate:
curl -sk -H 'Host: example.com' https://<CANDIDATE_IP>/ | head -n 20
echo | openssl s_client -connect <CANDIDATE_IP>:443 -servername example.com 2>/dev/null | openssl x509 -noout -subject -ext subjectAltName
nmap --script ssl-cert -p 443 <CANDIDATE_IP>
If the cert answers with CN/SAN=example.com (or title/Server matches the site), that's the real IP.
| Tool | Replacement reason |
|---|---|
subfinder | Replaced by crt.sh + crt.name + OTX + urlscan + VT + SecurityTrails (all via API, nothing to install) |
webanalyze | Reliable tech detection requires a paid API (Wappalyzer/BuiltWith) — out of scope |
subjs / getJS | Replaced by built-in <script src> extraction (section 12) |
jshunter | Replaced by built-in endpoint regex (section 12) |
js_snitch | No public-API equivalent |
dnsrecon -d | Equivalent in section 8 (NS/MX/SOA/AXFR via DoH + dig) |
httpx-toolkit | Partial equivalent in section 10 (status/server per host) |
ffuf / gobuster | Built-in dirscan with curated wordlist + xargs -P (section 15) — for full fuzzing use SecLists: ffuf -u https://TARGET/FUZZ -w raft-medium-directories.txt |
