# OSINT CTF — Supercharged skill ## Methodology checklist 1. Scope the challenge text: names, handles, emails, domains, photos, coords, timestamps, flag format. 2. Passive only: public web, archives, WHOIS/crt.sh, reverse image, EXIF, social footprinting. 3. Correlate ≥2 independent sources before proposing a flag. 4. Log timeline in a local journal (not committed with secrets). 5. Never submit flags without human/team OK. Never SE / scan / bruteforce / exploit / fuzz. ## Models - Orchestrator / sub-agents: **DeepSeek**, **OpenRouter**, or **Nous Research (Hermes)** — set in `.env` - Helper: `python3 tools/llm_providers.py status` · docs: `../docs/PROVIDERS.md` ## Delegation Hard OSINT / long context / vision → sub-agent provider (often OpenRouter multimodal or Hermes-4-405B); orchestrator stays on the chosen primary provider. ## Companion files - `../skills/archival-hunt.md` — multi-archive SOP - `../skills/writeups-digest.md` — technique digest - `../skills/osint-ctf-corpus/` — offline write-up corpus - `../knowledge/` — patterns learned in live CTFs (sanitized) - `../opsec/REGLES-DOR-OPSEC.md` — mandatory before network I/O - `../tools/` — CTFd, OSINTMapper, OSINT Industries, Rosint Reddit, Instant Username, Maigret, LLM providers helpers - `../docs/PROVIDERS.md` — DeepSeek / OpenRouter / Nous Research setup - `../skills/rosint-reddit/` — deleted/old Reddit history (Arctic Shift + PullPush) - `../skills/username-search/` — Instant Username–first pivots; Industries when keyed - `../skills/maigret/` — Maigret username OSINT (subset + optional full engine) ## Soft crawl / anti-ban - Dedicated `$CTF_UA` ≠ desktop UA - Dedicated API keys ≠ personal daily keys - ≤5 navigations per lead; stop on 403/429 - Prefer archives over live scrape - **Forbidden:** fuzz, wordlists, path guessing, exploits ## Tooling (bring your own keys) See root `.env.example` and `docs/TOOLS.md`.
