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.

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

Expected Output

{
  "name": "APT29 TTPs",
  "domain": "enterprise-attack",
  "techniques": [
    {"techniqueID": "T1566.001", "score": 1, "comment": "Spearphishing Attachment"},
    {"techniqueID": "T1059.001", "score": 1, "comment": "PowerShell"}
  ]
}

Verification Criteria

Confirm successful execution by validating:

• [ ] All prerequisite tools and access requirements are satisfied
• [ ] Each workflow step completed without errors
• [ ] Output matches expected format and contains expected data
• [ ] No security warnings or misconfigurations detected
• [ ] Results are documented and evidence is preserved for audit

Compliance Framework Mapping

This skill supports compliance evidence collection across multiple frameworks:

• SOC 2: CC7.1 (Monitoring), CC7.2 (Anomaly Detection)
• ISO 27001: A.6.1 (Threat Intelligence), A.16.1 (Security Incident Management)
• NIST 800-53: PM-16 (Threat Awareness), RA-3 (Risk Assessment), SI-5 (Security Alerts)
• NIST CSF: ID.RA (Risk Assessment), DE.AE (Anomalies & Events)

Claw GRC Tip: When this skill is executed by a registered agent, compliance evidence is automatically captured and mapped to the relevant controls in your active frameworks.

Deploying This Skill with Claw GRC

Agent Execution

Register this skill with your Claw GRC agent for automated execution:

# Install via CLI
npx claw-grc skills add analyzing-threat-actor-ttps-with-mitre-navigator

# Or load dynamically via MCP
grc.load_skill("analyzing-threat-actor-ttps-with-mitre-navigator")

Audit Trail Integration

When executed through Claw GRC, every step of this skill generates tamper-evident audit records:

• SHA-256 chain hashing ensures no step can be modified after execution
• Evidence artifacts (configs, scan results, logs) are automatically attached to relevant controls
• Trust score impact — successful execution increases your agent's trust score

Continuous Compliance

Schedule this skill for recurring execution to maintain continuous compliance posture. Claw GRC monitors for drift and alerts when re-execution is needed.
