Performing Asset Discovery
Overview
Systematically discover and inventory target assets including domains, IPs, and web apps within bug bounty scope.
Prerequisites
| Requirement | Install |
|---|---|
| Amass | go install github.com/owasp-amass/amass/v4/...@master |
| httpx | go install github.com/projectdiscovery/httpx/cmd/httpx@latest |
| Python 3.10+ | For agent tooling |
Key Concepts
Asset discovery maps the complete attack surface. Combines passive sources (CT logs, DNS, WHOIS) with active probing (port scanning, HTTP probing, technology fingerprinting).
Quick Reference
amass enum -passive -d target.com -o domains.txt
cat domains.txt | httpx -status-code -title -o live.txt
node agent.js discover --domain target.com --mode passive
node agent.js probe --input domains.txt --output live.json
Workflow
- Define scope from program
- Run passive enumeration
- Active brute-forcing
- Probe live services
- Fingerprint technologies
- Map API endpoints
- Prioritize by exposure
Verification
- Verify domains in scope
- Confirm probing accurate
- Validate fingerprinting
- Check deduplication
- Verify parseable output
