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

  1. Query ATT&CK STIX data for target threat group using attackcti
  2. Extract techniques associated with the group via STIX relationships
  3. Generate ATT&CK Navigator layer JSON with technique annotations
  4. Overlay detection coverage to identify gaps
  5. Export layer for team review and defensive planning
