Bug Bounty Master Workflow
Full pipeline: Recon -> Learn -> Hunt -> Validate -> Report. One skill for everything.
THE ONLY QUESTION THAT MATTERS
> **"Can an attacker do this RIGHT NOW against a real user who has taken NO unusual actions -- and does it cause real harm (stolen money, leaked PII, account takeover, code execution)?"** > > If the answer is NO -- **STOP. Do not write. Do not explore further. Move on.**
Theoretical Bug = Wasted Time. Kill These Immediately:
| Pattern | Kill Reason | |---|---| | "Could theoretically allow..." | Not exploitable = not a bug | | "An attacker with X, Y, Z conditions could..." | Too many preconditions | | "Wrong implementation but no practical impact" | Wrong but harmless = not a bug | | Dead code with a bug in it | Not reachable = not a bug | | Source maps without secrets | No impact | | SSRF with DNS-only callback | Need data exfil or internal access | | Open redirect alone | Need ATO or OAuth chain | | "Could be used in a chain if..." | Build the chain first, THEN report |
**You must demonstrate actual harm. "Could" is not a bug. Prove it works or drop it.**
---
CRITICAL RULES
1. **READ FULL SCOPE FIRST** -- verify every asset/domain is owned by the target org 2. **NO THEORETICAL BUGS** -- "Can an attacker steal funds, leak PII, takeover account, or execute code RIGHT NOW?" If no, STOP. 3. **KILL WEAK FINDINGS FAST** -- run the 7-Question Gate BEFORE writing any report 4. **Validate before writing** -- check CHANGELOG, design docs, deployment scripts FIRST 5. **One bug class at a time** -- go deep, don't spray 6. **Verify data isn't already public** -- check web UI in incognito before reporting API "leaks" 7. **5-MINUTE RULE** -- if a target shows nothing after 5 min probing (all 401/403/404), MOVE ON 8. **IMPACT-FIRST HUNTING** -- ask "what's the worst thing if auth was broken?" If nothing valuable, skip target 9. **CREDENTIAL LEAKS need exploitation proof** -- finding keys isn't enough, must PROVE what they access 10. **STOP SHALLOW RECON SPIRALS** -- don't probe 403s, don't grep for analytics keys, don't check staging domains that lead nowhere 11. **BUSINESS IMPACT over vuln class** -- severity depends on CONTEXT, not just vuln type 12. **UNDERSTAND THE TARGET DEEPLY** -- before hunting, learn the app like a real user 13. **DON'T OVER-RELY ON AUTOMATION** -- automated scans hit WAFs, trigger rate limits, find the same bugs everyone else finds 14. **HUNT LESS-SATURATED VULN CLASSES** -- XSS/SSRF/XXE have the most competition. Expand into: cache poisoning, Android/mobile vulns, business logic, race conditions, OAuth/OIDC chains, CI/CD pipeline attacks 15. **ONE-HOUR RULE** -- stuck on one target for an hour with no progress? SWITCH CONTEXT 16. **TWO-EYE APPROACH** -- combine systematic testing (checklist) with anomaly detection (watch for unexpected behavior) 17. **T-SHAPED KNOWLEDGE** -- go DEEP in one area and BROAD across everything else 18. **LEAD BOARD — never lose a lead** -- after recon run `python3 tools/lead_board.py ingest <target>` + `show` + `next`. Route each signal to its skill ("GraphQL → hunt-graphql"). `touch` when starting/killing/reporting. Focus on one lead; the board remembers the rest. Surface stale high-priority leads unprompted.
> **For the full hunting methodology** — 5-phase non-linear workflow, developer psychology framework, session discipline, tool routing by phase, and Wide/Deep route selection — see **`skills/bb-methodology/SKILL.md`**. > > **Tool catalogue:** `tools/README.md` (~50 tools). Orchestrator: `python3 tools/hunt.py --target T` (auto lead ingest; add `--graphql` / `--cve-hunt` as needed).

AUTH-AWARE HUNTING (when bugs live behind a login)
Anonymous recon misses the bugs that pay most. IDOR, BOLA, mass-assignment, privilege escalation, auth bypass, SSRF behind login, and most LLM/agent bugs are invisible until you log in. Load auth **once** at session start and every downstream tool (httpx, katana, ffuf, nuclei, dalfox, the SQLi / SSTI / upload PoC verifiers) sends those headers automatically.
# Pick ONE of these and run hunt.py normally:
python3 tools/hunt.py --target T --cookie 'session=eyJabc...'
python3 tools/hunt.py --target T --bearer 'eyJhbGciOi...'
python3 tools/hunt.py --target T --auth-file .private/T.json
# Or via env (persists for the shell):
export BBHUNT_COOKIE='session=eyJabc...'
python3 tools/hunt.py --target T
**For IDOR / BOLA hunts**, load two sessions and diff behavior:
python3 tools/hunt.py --target T --auth-file
