Offensive OSINT Methodology

Workflow

1. Define target scope (domain, org, person, crypto address, or geo subject)
2. Select applicable categories below based on scope
3. Work top-down within each category; pivot on discovered artifacts
4. Archive every key artifact: URL + timestamp + screenshot (PNG) + hash (SHA-256)
5. Log findings in JSONL with a run_id and tool versions for reproducibility
6. Suggest next steps based on what each tool returns
