Analyzing Threat Actor TTPs with MITRE ATT&CK

Overview

MITRE ATT&CK is a globally-accessible knowledge base of adversary tactics, techniques, and procedures (TTPs) based on real-world observations. This skill covers systematically mapping threat actor behavior to the ATT&CK framework, building technique coverage heatmaps using the ATT&CK Navigator, identifying detection gaps, and producing actionable intelligence reports that link observed IOCs to specific adversary techniques across the Enterprise, Mobile, and ICS matrices.

When to Use

• When investigating security incidents that require analyzing threat actor ttps with mitre attack
• 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 3.9+ with mitreattack-python, attackcti, stix2 libraries
• MITRE ATT&CK Navigator (web-based or local deployment)
• Understanding of ATT&CK matrix structure: Tactics, Techniques, Sub-techniques
• Access to threat intelligence reports or MISP/OpenCTI for threat actor data
• Familiarity with STIX 2.1 Attack Pattern objects

Key Concepts

ATT&CK Matrix Structure

The ATT&CK Enterprise matrix organizes adversary behavior into 14 Tactics (the "why") containing Techniques (the "how") and Sub-techniques (specific implementations). Each technique has associated data sources, detections, mitigations, and real-world procedure examples from observed threat groups.

Threat Group Profiles

ATT&CK catalogs over 140 threat groups (e.g., APT28, APT29, Lazarus Group, FIN7) with documented technique usage. Each group profile includes aliases, targeted sectors, associated campaigns, software used, and technique mappings with procedure-level detail.

ATT&CK Navigator

The ATT&CK Navigator is a web-based tool for creating custom ATT&CK matrix visualizations. Analysts create layers (JSON files) that annotate techniques with scores, colors, comments, and metadata to visualize threat actor coverage, detection capabilities, or risk assessments.

Workflow

Step 1: Query ATT&CK Data Programmatically

from attackcti import attack_client
import json

# Initialize ATT&CK client (queries MITRE TAXII server)
lift = attack_client()

# Get all Enterprise techniques
enterprise_techniques = lift.get_enterprise_techniques()
print(f"Total Enterprise techniques: {len(enterprise_techniques)}")

# Get all threat groups
groups = lift.get_groups()
print(f"Total threat groups: {len(groups)}")

# Get specific group by name
apt29 = [g for g in groups if 'APT29' in g.get('name', '')]
if apt29:
    group = apt29[0]
    print(f"Group: {group['name']}")
    print(f"Aliases: {group.get('aliases', [])}")
    print(f"Description: {group.get('description', '')[:200]}")

Step 2: Map Threat Actor to ATT&CK Techniques

from attackcti import attack_client

lift = attack_client()

# Get techniques used by APT29
apt29_techniques = lift.get_techniques_used_by_group("G0016")  # APT29 group ID

technique_map = {}
for entry in apt29_techniques:
    tech_id = entry.get("external_references", [{}])[0].get("external_id", "")
    tech_name = entry.get("name", "")
    description = entry.get("description", "")
    tactic_refs = [
        phase.get("phase_name", "")
        for phase in entry.get("kill_chain_phases", [])
    ]

    technique_map[tech_id] = {
        "name": tech_name,
        "tactics": tactic_refs,
        "description": description[:300],
    }

print(f"\nAPT29 uses {len(technique_map)} techniques:")
for tid, info in sorted(technique_map.items()):
    print(f"  {tid}: {info['name']} [{', '.join(info['tactics'])}]")

Step 3: Generate ATT&CK Navigator Layer

import json

def create_navigator_layer(group_name, technique_map, description=""):
    """Generate ATT&CK Navigator layer JSON for a threat group."""
    techniques_list = []
    for tech_id, info in technique_map.items():
        techniques_list.append({
            "techniqueID": tech_id,
            "tactic": info["tactics"][0] if info["tactics"] else "",
            "color": "#ff6666",  # Red for observed techniques
            "comment": info["description"][:200],
            "enabled": True,
            "score": 100,
            "metadata": [
                {"name": "group", "value": group_name},
            ],
        })

    layer = {
