🛠️ Tool
===================
Opening: TDO Standalone Extractor is a self-contained tool for extracting Cyber Threat Intelligence (CTI) from documents. It targets analysts who need structured CTI from heterogeneous sources and automates conversion to machine-readable schemas.
Key Features:
• Multi-format support: processes PDF, DOCX, TXT, and Markdown inputs.
• Comprehensive schema: emits a CTI schema covering 12 entity types and 24 relationship types with rich properties.
• LLM integration: leverages Google Gemini models with automatic fallback parsing for resilient extraction.
• Detection & flow outputs: generates evidence-backed detection opportunities and an Attack-Flow JSON mapping to MITRE ATT&CK.
• Structured reliability: uses pydantic schemas to validate outputs and report parsing success.
• Parallel processing: supports concurrent file processing with progress tracking and job controls.
Technical Implementation:
• Core extraction relies on LLM-driven entity and relation parsing with structured output prompts and schema validation using pydantic models.
• Gemini serves as the primary model with configurable model selection and retry/backoff parameters conceptually managed via environment configuration.
• Outputs include per-file {filename}_extracted.json and human-readable Markdown summaries; optional artifacts include Attack Flow JSON and CSV summaries.
Use Cases:
• Automating ingestion of vendor reports and feeds into CTI platforms.
• Producing detection rule candidates with supporting evidence for SOC engineers.
• Feeding structured ATT&CK flow artifacts into threat modeling and reporting pipelines.
Limitations:
• Dependence on external LLM access and model availability for parsing fidelity.
• Quality of extraction tied to input document clarity and LLM hallucination risk; validation via pydantic mitigates schema errors but not semantic gaps.
• No built-in deployment orchestration; environment-based configuration required conceptually for API keys and model selection.
