# Offensive OSINT — External Red-Team Arsenal
> v3.0 — Refactored 2026-05-02 from a 4,168-line monolith into a lean SKILL.md (~400 lines) plus 15 modular reference files in references/. Detail content loads on demand — Claude reads only the reference files relevant to the current task.
0. When to use / When NOT
Use this skill when:
- You need concrete probe paths, wordlists, regexes, payloads, scoring rules, or tool URLs.
- You're executing reconnaissance and need the actual technical reference (vs. methodology).
- You're building a recon automation and need specific lists to seed it.
- The user is asking for active exploitation, post-exploitation, or anything past reconnaissance.
- The user is asking for defensive / blue-team detections.
- The target's authorization isn't established — see §1.
1. Authorization & Legal Posture
For assets the operator owns or has written authorization to assess. Soft scope check before acting against an unverified third-party target — see methodology skill §1 for the full posture.
2. Confidence Levels
- TENTATIVE — plausible based on indirect evidence (snippet-only dork match, single-source asset, inferred email pattern).
- FIRM — directly observed (subdomain resolves, HEAD-confirmed bucket exists, banner returned).
- CONFIRMED — verified via independent corroboration OR direct verification (live PMAK validation, multiple sources agree, listable bucket with object retrieval).
3. Output Format Conventions
Findings should carry: id, module, asset_key, category, severity (info/low/medium/high/critical), confidence, title, description, evidence (url + UTC timestamp + sha256 + raw ≤ 2 KiB), references, remediation. UTC timestamps everywhere.
4. Source Hygiene & Citations
URL + UTC timestamp + SHA-256 + tool version + run_id, every artifact. PNG screenshots, JSONL run logs, raw HTTP captures capped at 2 KiB body.
5. Do NOT
- Don't paste creds/PII/session tokens into cloud LLMs.
- Don't run destructive probes outside DEEP/
--aggressive. - Don't use validated credentials for anything except read-only liveness check.
- Don't single-source attribute.
- Don't assume vendor labels are ground truth.

How to use this skill
This skill is a lean operational index. Most concrete data (wordlists, regexes, dorks, endpoint catalogs, severity examples) lives in the references/ subfolder, organized by topic.
Workflow when this skill triggers:
- Read this SKILL.md to anchor on principles (§0-5), scoring rubrics (§20-21), attack-path templates (§39), and the references index below.
- For task-specific data, read only the reference file(s) you need — do NOT pull all 15. Each reference is self-contained.
- Use the
bug-bountyskill for the local toolkit at~/security-research/bug-bounty-resources/andosint-methodologyfor the planning framework.
- Single-class question (e.g., "what's the regex for AWS keys?") → load
secret-patterns.mdonly. - Multi-class engagement (e.g., "do an external recon on target.com") → load
probes-and-wordlists.mdfirst, then add others as the engagement narrows. - Severity / triage question → load
severity-matrix.md.

20. Endpoint Interest Score — 0–100 rubric
For every classified endpoint (§22 in methodology skill), apply this rubric:
| Signal | Points | Conditions |
|---|---|---|
| Unauth write | +40 | POST/PUT/DELETE/PATCH endpoint returns 200/201/202/204 anonymously. |
| Open GraphQL introspection | +35 | __schema query returns full type list anonymously. |
| Verb tampering bypass | +30 | OPTIONS reveals method not documented; that method is accessible. |
| Reflected CORS + credentials | +25 | Access-Control-Allow-Origin reflects request Origin AND Access-Control-Allow-Credentials: true. |
| Sensitive keyword in path | +20 | Path matches one of: admin, internal, debug, user, password, token, key, export, upload, backup, config, secret, private, delete, purge, wipe. |
| Schema leak in error | +20 | Response body contains stack trace, ORM error class, framework signature (e.g., ActiveRecord::RecordNotFound, org.hibernate.exception.*, django.db.utils.IntegrityError). |
| API key in URL | +15 | Path or query string contains api_key=, apikey=, token=, access_token=. |
| Wildcard CORS | +10 | Access-Control-Allow-Origin: *. |
| Missing rate-limit headers | +10 | No RateLimit-* / X-RateLimit-* headers; no Retry-After after rapid requests. |
| Score | Severity |
|---|---|
| ≥ 90 | CRITICAL |
| 70–89 | HIGH |
| 50–69 | MEDIUM |
| 25–49 | LOW |
| < 25 | INFO |
attack_path_hint in evidence (see §29).
21. Mobile App Ownership Confidence — 0–100 rubric
Before running deep APK static analysis, score whether the discovered app actually belongs to the target. Threshold: ≥70 = accept.
| Signal | Points |
|---|---|
Package reverse-DNS matches target domain (e.g., com.acme.android ⟂ acme.com) | +40 |
Developer email is <anything>@<target-domain> | +25 |
| Developer website URL is the target domain (or a confirmed sibling brand domain) | +20 |
| App name contains a brand keyword from operator-supplied brand list | +10 |
| App has ≥ minimum review-score threshold (default 20 reviews) | +5 |
mobile_review_pending and shown but not analyzed. Operator can re-score with --mobile-ownership-threshold 50 for noisier collection.
39. Attack-Path Hint Patterns
When emitting a HIGH/CRITICAL API endpoint finding (score ≥ 70), include a one-sentence attack_path_hint in evidence so the operator knows where to start exploiting. Templates:
| Trigger | Attack-path hint |
|---|---|
| Unauth POST / PUT / DELETE | "Unauthenticated {method} {path} — try IDOR + privilege escalation; check whether numeric IDs are sequential or guessable." |
| Open GraphQL introspection | "Open GraphQL introspection on {path} — enumerate mutations, look for createUser, setRole, transferFunds-shaped names; pivot to broken-auth or business-logic flaws." |
| Reflected CORS + creds | "Reflected CORS with credentials on {path} — host CSRF page on attacker-controlled origin; victim's browser will leak {sensitive-data-hint}." |
| Wildcard CORS + sensitive | "Wildcard CORS on {path} returning user-tied data without creds — exfiltrate via cross-origin fetch from any page victim visits." |
| Verb tampering | "Verb tampering: {hidden-method} allowed on documented-{visible-method}-only endpoint → likely missing-method-check authz bug; try {hidden-method} {path} with valid auth." |
| API key in URL | "API key in URL: ?{param}=... — token leaks to access logs, browser history, Referer headers, third-party CDNs. Check Wayback / Google for cached copies." |
| Schema leak in error | "Schema leak in error response — framework signature {framework} exposed; map to known {framework} vulns and craft targeted payloads." |
| Sensitive keyword | "Path contains '{keyword}' — review for direct object reference, mass-assignment, or hidden admin functionality." |
| Open RTDB Firebase | "Open Firebase RTDB at https://{project}.firebaseio.com/.json — read everything, then test write at /<random-key>.json with PUT to gauge ACL scope." |
| Listable cloud bucket | "Listable {provider} bucket {bucket} — recursive object listing + content-type analysis; look for backups, logs, customer data, AWS keys in JSON configs." |
| .git exposed | "Exposed .git/config on {host} — reconstruct repository with git-dumper or githacker; full source history." |
| .env exposed | "Exposed .env on {host} — grep for _KEY, _SECRET, _TOKEN, _PASSWORD; validate all credentials read-only via §23 validators." |
| /actuator/env | "Spring Boot /actuator/env exposed — dump environment variables; look for spring.datasource.password, JWT secrets, cloud creds." |
| /actuator/heapdump | "Spring Boot /actuator/heapdump exposed — download HPROF, run jhat or VisualVM, search for cleartext secrets in heap strings." |
| Open Elasticsearch | "Open Elasticsearch on {host}:9200 — /_cat/indices?v for index list; sample documents from each high-value index; test write to /test-idx/_doc to gauge ACL." |
| Open Redis | "Open Redis on {host}:6379 — INFO, KEYS *, sample reads; check for write access via CONFIG SET then BGSAVE to write authorized_keys." |
| Open MongoDB | "Open MongoDB on {host}:27017 — show dbs, show collections, sample find queries; check user collection for password hashes." |
| Subdomain takeover | "CNAME for {host} points to unclaimed {provider} resource → register {takeover-target} on {provider} to serve content from {host}; pivot to phishing or content injection on the trusted domain." |
| Open kubelet | "Open kubelet on {host}:10250 — GET /pods to list; POST /run/<ns>/<pod>/<container> for in-container exec without K8s API auth." |
| Open etcd | "Open etcd on {host}:2379 — etcdctl get / --prefix --keys-only for full cluster state; secrets stored under /registry/secrets/." |
| K8s API anonymous | "Kubernetes API on {host}:6443 with anonymous-auth — kubectl --server=https://{host}:6443 --insecure-skip-tls-verify get pods --all-namespaces." |
| Citrix unpatched | "Citrix NetScaler version {ver} on {host} — vulnerable to CVE-{cve} (KEV-listed); see vendor advisory; do not exploit but flag for client immediate patching." |
| F5 BIG-IP TMUI exposed | "F5 BIG-IP TMUI on {host} reachable; CVE-2022-1388 / CVE-2023-46747 KEV applicable; advise immediate patching to vendor-released hotfix." |
| VMware vCenter accessible | "vCenter at {host} accessible without VPN; CVE-2021-21972 RCE if unpatched; check version banner." |
| Cloud function URL unauth | "AWS Lambda Function URL at {url} accessible anonymously — review IAM auth configuration; if unauthenticated by design, audit input validation aggressively." |
| npm typosquat candidate | "Package name {candidate} is unregistered + similar to target's published {official} — typosquat takeover risk; advise client to defensively register." |
| DMARC missing/permissive | "DMARC p=none on {domain} — spoof of {anything}@{domain} deliverable to recipients; recommend enforcement to p=quarantine or p=reject after observing reports." |
| Live AI API key (Anthropic/OpenAI) | "Validated sk-{provider}-... key with model access — quota cost can be exfiltrated; rotate immediately + audit usage logs in provider console." |
| Public Slack invite link | "Slack workspace invite link discoverable via search engine — anyone can join the workspace without approval; trivially access internal channels." |
| Open Docker registry | "Public Docker registry at {host} — GET /v2/_catalog lists images; pull and scan layers for embedded secrets." |
| Telegram bot token live | "Telegram bot token validated — getUpdates reveals bot recipients (admin chats); if getMe shows bot is in channels, full message read access." |
Sourcemap with sourcesContent[] | "Sourcemap on {host} includes embedded original sources — full frontend code reconstructable; grep for inline secrets and internal hostnames." |
