Develop Integration to Export Thread Data as Sigma Rules

[KadeMorton]

Is your feature request related to a problem? Please describe.
Thread currently does not support exporting TTPs and metadata into Sigma rule format, which limits its utility for detection engineering. This gap prevents users from leveraging insights generated in Thread to create SIEM-agnostic detection rules for operational use.

Describe the solution you'd like
Develop a feature that allows Thread to export TTPs and relevant metadata as Sigma rules. The export functionality should comply with Sigma specifications and include options for users to customize rule metadata such as title, description, log source, and tags. The feature should generate rules in a format ready for integration with supported SIEM platforms.

Describe alternatives you've considered

• Manually translating Thread data into Sigma rule format, which is error-prone and inefficient.
• Using third-party tools to create Sigma rules, which may lack integration with Thread’s unique insights and data structure.

Additional context
This feature will be implemented in phases:

1. Research Sigma Rule Specifications: Review Sigma documentation to understand format and requirements.
2. Design Sigma Rule Export Feature: Plan how Thread data will map to Sigma rules, including a user interface for export functionality.
3. Develop Export Functionality: Implement the ability to generate Sigma-compliant rules from Thread data.
4. Testing and Validation: Validate exported rules in supported SIEM platforms to ensure functionality and compliance.
5. Documentation: Provide a user guide with examples and instructions for using and integrating exported Sigma rules.
