Web2 recon pipeline — subdomain enumeration (subfinder, Chaos API, assetfinder), live host discovery (dnsx, httpx), URL crawling (katana, waybackurls, gau), directory fuzzing (ffuf), JS analysis (LinkFinder, SecretFinder), continuous monitoring (new subdomain alerts, JS change detection, GitHub commit watch). Use when starting recon on any web2 target or when asked about asset discovery, subdomain enum, or attack surface mapping.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# WEB2 RECON PIPELINE Full asset discovery from nothing to a prioritized URL list ready for hunting. --- ## THE 5-MINUTE RULE > If a target shows nothing interesting after 5 minutes of recon, move on. Don't burn hours on dead surface. **5-minute kill signals:** - All subdomains return 403 or static marketing pages - No API endpoints visible in URLs - No JavaScript bundles with interesting endpoint paths - nuclei returns 0 medium/high findings - No forms, no authentication, no user data --- ## STANDARD RECON PIPELINE ### Pre-Hunt: Always Run First ```bash TARGET="target.com" # Step 1: Chaos API (ProjectDiscovery — most comprehensive source) curl -s "https://dns.projectdiscovery.io/dns/$TARGET/subdomains" \ -H "Authorization: 15e77cfb-2300-426a-b8c3-fbfbf0ab17d4" \ | jq -r '.[]' > /tmp/subs.txt echo "[+] Chaos returned $(wc -l < /tmp/subs.txt) subdomains" # Step 2: subfinder (passive multi-source) subfinder -d $TARGET -silent | anew /tmp/subs.txt assetfinder --subs-only $TARGET | anew /tmp/subs.txt echo "[+] Total subdomains after all sources: $(wc -l < /tmp/subs.txt)" # Step 3: DNS resolution + live host check …

How to install
mdr add mikacr1138/claude-bug-bounty/web2-recon@sha256:3f101e09372f5a83The line at the top of this page pins the label git:20260317.a154787, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
