undermybelt Analyzing Threat Actor TTPs with MITRE Navigator
Overview
The MITRE ATT&CK Navigator is a web application for annotating and visualizing ATT&CK matrices. Combined with the attackcti Python library (which queries ATT&CK STIX data via TAXII), analysts can programmatically generate Navigator layer files mapping specific threat group TTPs, compare multiple groups, and assess detection coverage gaps against known adversaries.
When to Use
- When investigating security incidents that require analyzing threat actor ttps with mitre navigator
- When building detection rules or threat hunting queries for this domain
- When SOC analysts need structured procedures for this analysis type
- When validating security monitoring coverage for related attack techniques
Prerequisites
- Python 3.8+ with attackcti and stix2 libraries installed
- MITRE ATT&CK Navigator (web UI or local instance)
- Understanding of STIX 2.1 objects and relationships
Steps
- Query ATT&CK STIX data for target threat group using attackcti
- Extract techniques associated with the group via STIX relationships
- Generate ATT&CK Navigator layer JSON with technique annotations
- Overlay detection coverage to identify gaps
- Export layer for team review and defensive planning
