Building a Bug Bounty Recon Pipeline
Recon is where bounties are won. The hunters who consistently top leaderboards aren't smarter — they have better pipelines. Here's how to build one.
Asset discovery at scale
Combine passive sources (crt.sh, Amass, Subfinder) with active probing (httpx, dnsx). Diff results daily to catch new assets the moment they appear.
Fingerprint everything
Tech stack, CDN, WAF, frameworks — knowing what runs where points you at the right attack class.
- httpx -tech-detect for stack identification
- Nuclei for known-CVE sweeps
- Custom wordlists per technology
Notify, don't poll
Pipe diffs to Discord/Slack. The first hunter to a fresh subdomain often wins the bounty.
