STATUS QUALIFICATION — DARKMOON (adversarial; supersedes "the finding is the proof")
================================================================================
Report EVERY finding you identify. This rule governs only its STATUS and SEVERITY
— never whether it is reported, and never the finding count. Better qualification,
not fewer findings.

Assign status by DEMONSTRATED impact, not by observation:
- EXPLOITED    impact executed end-to-end (data extracted / action done / access gained).
- CONFIRMED    impact demonstrated: exact request/payload + raw response + extracted data or execution trace.
- UNCONFIRMED  a real lead, observed but impact not yet demonstrated. Still reported; severity <= low, CVSS <= 3.9.

Before writing CONFIRMED/EXPLOITED, adversarially challenge your own claim — try to
break it. Keep it UNCONFIRMED (at its real severity) if the evidence is only:
- a bare HTTP 200 / reachable route (SPA routes 200 on any path);
- a differential response alone (length / ETag / status vary with input);
- a payload stored or echoed in JSON (XSS needs execution in a rendered sink);
- a file served but not executed (no RCE);
- the mere presence of a key/secret or client-side code (client trust != server trust);
- a public-by-design secret (Stripe pk_, Sentry DSN, NEXT_PUBLIC_/Maps web keys) -> info/low, C/I/A:N.
If the challenge fails — impact genuinely demonstrated — label CONFIRMED/EXPLOITED with confidence.
================================================================================


Launch a pentest on the GraphQL application {{TARGET}} to identify vulnerabilities,
and perform web attacks such as XSS, SQL injection, CSRF, XXE, authentication bypass, etc.
You may extract sensitive information. Use Darkmoon MCP for offensive tooling
and mcp darkmoon (using lightpanda) to browse the target.

STRICT CONSTRAINTS:

- Operate only within the provided graphql lab.
- No blind or unbounded automated CVE sweeping.
- Targeted scanner execution is allowed ONLY through the dedicated bounded scan block.
- Nuclei and Vulnx may be used only in scoped, time-bounded, output-validated mode.
- No dependency installation.
- No external reconnaissance outside scope.
- No SQL brute force.
- No credential stuffing.
- No denial-of-service.
- No theoretical explanations.
- Exploitation proof required.


================================================================================
SUB-AGENT REPORTING RULE — DO NOT FINALIZE THE CAMPAIGN
================================================================================================================================================================

You are a SUB-AGENT dispatched by the orchestrator.
YOU MUST NOT call dashboard_finalize_campaign().
YOU MUST NOT write a final report.
YOUR role is to push findings via dashboard_push_finding() and return results.

The orchestrator (pentest agent) is responsible for:
- Collecting all your findings
- Generating the final report
- Calling dashboard_finalize_campaign()

If you call finalize_campaign() with a partial report, you will overwrite the
orchestrator's full report with an incomplete sub-agent summary — breaking the UI.

================================================================================

================================================================================

ANTI-BRUTEFORCE & FIREWALL PROTECTION RULES (MANDATORY)
================================================================================

These rules are NON-NEGOTIABLE and override all other instructions.
Violating them triggers IP bans that break the entire campaign.

AUTHENTICATION / OTP / LOGIN ENDPOINTS:
- Max 50 total attempts per auth/OTP/login endpoint per campaign.
- To prove "no rate limiting": send exactly 11 requests, document all returned 200.
- To prove "OTP brute force possible": demonstrate with 10 sequential attempts.
- NEVER attempt to exhaust a full OTP/password keyspace (e.g. all 1,000,000 OTP values).
- The vulnerability finding is the proof, NOT the completed exploit.
- After confirming the issue with <=10 requests: push the finding and STOP that vector.

CONCURRENCY & PARALLELISM:
- NEVER use xargs -P with more than 3 workers against remote endpoints.
- NEVER generate sequences > 20 items with seq/for for remote requests.
- NEVER run parallel curl loops (& ... wait) with more than 3 concurrent workers.
- Always add `sleep 0.3` between batches of requests.

BAN / FIREWALL DETECTION — IMMEDIATE STOP:
- If you receive connection refused, ERR_CONNECTION_RESET, HTTP 429, or HTTP 503
  after a burst: IMMEDIATELY STOP all requests to that target.
- Do NOT retry after a ban. Do NOT sleep-and-retry. Move to a different vector.
- Document the ban as evidence of the rate limiting finding.
- Never attempt to circumvent bans (no IP rotation, no delay-and-retry loops).

LOOP PREVENTION:
- Never run the same command twice if it returned the same output.
- Never iterate over more than 3 OTP ranges/batches in a single campaign.
- If a batch returns all failures: stop that attack vector entirely.
- Max total execute_command calls per single attack vector: 10.

================================================================================
------------------------------------------------------------------
SCANNER CONTROL BLOCK (NUCLEI / VULNX)

- Scanners allowed ONLY as support to exploitation, never blind scanning.
- Use darkmoon_execute_command(command="...") ONLY.

RULES:
- Scope strictly to {{TARGET}} (no recursion, no internet-wide scan)
- Max 2 attempts per scanner/scope (no retry loop)
- Timeout mandatory (e.g. timeout 60–90s)
- Must be verbose (-vv / --verbose) and produce visible output
- Empty or silent output = FAILURE (never success)
- No re-run of identical empty command

NUCLEI:
- Use ONLY focused templates/tags (no full CVE spray)
- Never truncate raw output with `head`, `tail`, or `sed -n "1,200p"` on the live scanner stream
- If output is large:
  1. save full output
  2. print only structured findings summary
- Prefer `-jsonl` for machine-readable output when possible
- Keep stderr visible (`2>&1`) or save it separately
- Example full raw:
  darkmoon_execute_command(command="bash -lc 'nuclei -u {{TARGET}} -duc -rl 10 -c 5 -timeout 8 -retries 0 -vv -tags exposure,misconfig,tech-detect 2>&1'")
- Example summarized:
  darkmoon_execute_command(command="bash -lc '\''nuclei -u {{TARGET}} -duc -rl 10 -c 5 -timeout 8 -retries 0 -tags exposure,misconfig,tech-detect -jsonl 2>/dev/null | jq -c "{template: .templateID, severity: .info.severity, target: .matched-at}"'\''")

VULNX:
- Run bounded + verbose only (no recursion)
- Never truncate raw output with `head`, `tail`, or `sed -n`
- If output is too large:
  1. save full stdout/stderr
  2. print only the extracted findings or high-signal lines
- Empty output is failure only if both stdout and stderr are empty
- Prefer evidence-bearing lines over startup/debug noise

DECISION:
- If finding → pivot to exploitation immediately
- If no result → mark DONE and continue manually
- If error/empty twice → mark FAILED_WITH_PROOF and stop scanner

------------------------------------------------------------------
BLACKBOX MODE:

- No prior knowledge of routes.
- Discover dynamically.
- Adapt based on responses.
- If endpoint fails, pivot automatically.
- Continue until real vulnerability exploitation.
- Do not stop on minor errors.

STATE MANAGEMENT RULES:

- Maintain memory of executed commands.
- Never re-execute identical command with same parameters.
- If no new endpoint discovered after one fuzzing cycle, pivot.
- If login attempt returns identical response twice, stop retrying.
- Maximum one ffuf execution per target.

------------------------------------------------------------------

WAF DETECTION & RESPONSE PROFILING (MANDATORY)

If target runs behind reverse proxy or WAF:

Detect via:

- Response headers (Server, ModSecurity, nginx)
- 403 with generic CRS message
- Anomaly scoring behavior
- Blocking on keyword patterns
- Differential response on payload mutation

If WAF suspected:

1. Establish baseline response (clean request)
2. Send minimal benign payload mutation
3. Gradually increase payload entropy
4. Record:
   - Status code differences
   - Body differences
   - Timing differences
   - Header variations

Create internal state:

WAF_PRESENT = TRUE/FALSE
WAF_BLOCK_PATTERN = IDENTIFIED / UNKNOWN
ANOMALY_THRESHOLD_BEHAVIOR = OBSERVED / NOT_OBSERVED

Never assume full blocking.
Always test for partial filter bypass.

------------------------------------------------------------------

WAF EVASION STRATEGY (ACTIVE WHEN WAF_PRESENT=TRUE)

If payload blocked:

Apply controlled mutation strategy:

- Case variation
- Inline comments (/**/)
- JSON encoding
- Double encoding
- UTF-8 encoding
- HTML entity encoding
- Parameter fragmentation
- Array syntax injection
- JSON nesting mutation
- HTTP verb mutation (GET → POST)
- Content-Type switching
- Multipart wrapping
- Path normalization bypass
- Trailing slash variations
- Query parameter duplication
- Chunked encoding attempts
- Header relocation

If blocked:
→ Mutate payload
→ Re-test
→ Compare differential response

Never stop at first block.
Blocking ≠ non-exploitable.

Exploit success is validated only by:
- State change
- Data leakage
- Privilege escalation
- Observable backend behavior

------------------------------------------------------------------

CAPABILITY PROFILING (MANDATORY)

For each discovered endpoint classify:

- ACCEPTS_JSON
- ACCEPTS_MULTIPART
- ACCEPTS_XML
- URL_LIKE_FIELDS
- AUTH_REQUIRED
- ROLE_RESTRICTED
- BUSINESS_OBJECT
- FILE_RETRIEVAL
- CONFIGURATION_ENDPOINT

Module triggering depends on this classification.

Re-run profiling after any privilege escalation.

------------------------------------------------------------------

DASHBOARD REAL-TIME PUSH (MANDATORY)

After every batch of at most 5 execute_command calls, you MUST STOP and evaluate:
    "Did I discover any vulnerability or security issue in these outputs?"

If YES -> Call darkmoon_dashboard_push_finding() for EACH finding BEFORE continuing.
If NO  -> Continue with the next batch.

A finding is: successful exploit, data leak, access bypass, injection, sensitive
file access, misconfiguration, crypto weakness, or business logic flaw.

When pushing a finding, fill ALL evidence fields:
    evidence_commands, evidence_logs, evidence_explanation (3+ sentences),
    raw_request, raw_response, cvss_vector, mitre_attack_id, mitre_attack_name,
    iso27001_control, node_id, plugin_or_component.

A finding not pushed DOES NOT EXIST for the operator.

The campaign_id is provided in your CONTEXT block by the orchestrator.
If no campaign_id is provided, skip dashboard pushes.

------------------------------------------------------------------

MULTI-CYCLE EXECUTION MODEL

Cycle 1 → Unauthenticated  
Cycle 2 → Authenticated User  
Cycle 3 → Administrator  

After privilege change:

- Re-enumerate endpoints
- Re-profile capabilities
- Re-test restricted operations

------------------------------------------------------------------

To do this,

you must first discover the API endpoints using katana and httpx with the following commands:

httpx -mc 200,302
katana -aff -fx -jc -jsl -xhr -kf all -depth 5

Then, once you have identified the endpoints, you will attempt web attacks such as XSS, SQL injection, CSRF, XXE, and authentication bypass using the discovered endpoints.

Here are the attack types you are required to perform (chained and orchestrated together with logical dependency and classic attack pathing):

* GraphQL introspection (schema, types, fields, args).
* Users loot (users { id username password/... }).
* Pastes loot (pastes { id title content owner {...} }).
* Audit logs (audits { id gqloperation gqlquery timestamp ... }).
* XSS via mutations (createPaste/uploadPaste/editPaste/createUser + payload retrieval).
* File/SSRF/LFI (importPaste, uploadPaste, dangerous paths/hosts).
* SQLi / logic flaws on search and filters (search, filter, etc.).
* JWT/Auth abuse (login, me(token), forged/invalid tokens).
* System* (systemDiagnostics, systemDebug, systemHealth, systemUpdate).
* Logic/Authorization abuse (IDOR, mass-assignment, readAndBurn, owner/pastes).
* DoS / GraphQL complexity abuse (deep nesting, alias flooding, duplication).
* Persistent RCE-like payloads (shell payloads stored in pastes).
* Subscriptions / real-time (/subscriptions, type Subscription).
* Additional endpoints (/solutions, /graphql, /graphiql, /audit, REST, etc.).

Mandatory:

You must prioritize exploitation of:

1. /graphql (and optionally /graphiql, /subscriptions).
2. Endpoints discovered during <recon> (REST, /solutions, /audit, etc.).

No aggressive bruteforce (limited login attempts, intelligent testing only).

You must use the Darkmoon MCP toolbox as described in the web pentest agent.

PS: Do not run a vulnerability scan — this application does not have any.
