Analyzing APT Group with MITRE ATT&CK Navigator
Overview
MITRE ATT&CK Navigator is a web-based tool for annotating and exploring ATT&CK matrices, enabling analysts to visualize threat actor technique coverage, compare multiple APT groups, identify detection gaps, and build threat-informed defense strategies. This skill covers querying ATT&CK data programmatically, mapping APT group TTPs to Navigator layers, creating multi-layer overlays for gap analysis, and generating actionable intelligence reports for detection engineering teams.
When to Use
- When investigating security incidents that require analyzing apt group 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 3.9+ with
attackcti, mitreattack-python, stix2, requests libraries
- ATT&CK Navigator (https://mitre-attack.github.io/attack-navigator/) or local deployment
- Understanding of ATT&CK Enterprise matrix: 14 Tactics, 200+ Techniques, Sub-techniques
- Access to threat intelligence reports or MISP/OpenCTI for threat actor data
- Familiarity with STIX 2.1 Intrusion Set and Attack Pattern objects
Key Concepts
ATT&CK Navigator Layers
Navigator layers are JSON files that annotate ATT&CK techniques with scores, colors, comments, and metadata. Each layer can represent a single APT group's technique usage, a detection capability map, or a combined overlay. Layer version 4.5 supports enterprise-attack, mobile-attack, and ics-attack domains with filtering by platform (Windows, Linux, macOS, Cloud, Azure AD, Office 365, SaaS).
APT Group Profiles in ATT&CK
ATT&CK catalogs over 140 threat groups with documented technique usage. Each group profile includes aliases, targeted sectors, associated campaigns, software used, and technique mappings with procedure-level detail. Groups are identified by G-codes (e.g., G0016 for APT29, G0007 for APT28, G0032 for Lazarus Group).
Multi-Layer Analysis
The Navigator supports loading multiple layers simultaneously, allowing analysts to overlay threat actor TTPs against detection coverage to identify gaps, compare multiple APT groups to find common techniques worth prioritizing, and track technique coverage changes over time.
Workflow
Step 1: Query ATT&CK Data for APT Group
from attackcti import attack_client
import json
lift = attack_client()
# Get all threat groups
groups = lift.get_groups()
print(f"Total ATT&CK groups: {len(groups)}")
# Find APT29 (Cozy Bear / Midnight Blizzard)
apt29 = next((g for g in groups if g.get('name') == 'APT29'), None)
if apt29:
print(f"Group: {apt29['name']}")
print(f"Aliases: {apt29.get('aliases', [])}")
print(f"Description: {apt29.get('description', '')[:300]}")
# Get techniques used by APT29 (G0016)
techniques = lift.get_techniques_used_by_group("G0016")
print(f"APT29 uses {len(techniques)} techniques")
technique_map = {}
for tech in techniques:
tech_id = ""
for ref in tech.get("external_references", []):
if ref.get("source_name") == "mitre-attack":
tech_id = ref.get("external_id", "")
break
if tech_id:
tactics = [p.get("phase_name", "") for p in tech.get("kill_chain_phases", [])]
technique_map[tech_id] = {
"name": tech.get("name", ""),
"tactics": tactics,
"description": tech.get("description", "")[:500],
"platforms": tech.get("x_mitre_platforms", []),
"data_sources": tech.get("x_mitre_data_sources", []),
}
Step 2: Generate Navigator Layer JSON
def create_navigator_layer(group_name, technique_map, color="#ff6666"):
techniques_list = []
for tech_id, info in technique_map.items():
for tactic in info["tactics"]:
techniques_list.append({
"techniqueID": tech_id,
"tactic": tactic,
"color": color,
"comment": info["name"],
"enabled": True,
"score": 100,
"metadata": [
{"name": "group", "value": group_name},
{"name": "platforms", "value": ", ".join(info["platforms"])},
],
})
layer = {
"name": f"{group_name} TTP Coverage",
"versions": {"attack": "16.1", "navigator": "5.1.0", "layer": "4.5"},
"domain": "enterprise-attack",
"description": f"Techniques attributed to {group_name}",
"filters": {
"platforms": ["Linux", "macOS", "Windows", "Cloud",
"Azure AD", "Office 365", "SaaS", "Google Workspace"]
},
"sorting": 0,
"layout": {
"layout": "side", "aggregateFunction": "average",
"showID": True, "showName": True,
"showAggregateScores": False, "countUnscored": False,
},
"hideDisabled": False,
"techniques": techniques_list,
"gradient": {"colors": ["#ffffff", color], "minValue": 0, "maxValue": 100},
"legendItems": [
{"label": f"Used by {group_name}", "color": color},
{"label": "Not observed", "color": "#ffffff"},
],
"showTacticRowBackground": True,
"tacticRowBackground": "#dddddd",
"selectTechniquesAcrossTactics": True,
"selectSubtechniquesWithParent": False,
"selectVisibleTechniques": False,
}
return layer
layer = create_navigator_layer("APT29", technique_map)
with open("apt29_layer.json", "w") as f:
json.dump(layer, f, indent=2)
print("[+] Layer saved: apt29_layer.json")
Step 3: Compare Multiple APT Groups
groups_to_compare = {"G0016": "APT29", "G0007": "APT28", "G0032": "Lazarus Group"}
group_techniques = {}
for gid, gname in groups_to_compare.items():
techs = lift.get_techniques_used_by_group(gid)
tech_ids = set()
for t in techs:
for ref in t.get("external_references", []):
if ref.get("source_name") == "mitre-attack":
tech_ids.add(ref.get("external_id", ""))
group_techniques[gname] = tech_ids
common_to_all = set.intersection(*group_techniques.values())
print(f"Techniques common to all groups: {len(common_to_all)}")
for tid in sorted(common_to_all):
print(f" {tid}")
for gname, techs in group_techniques.items():
others = set.union(*[t for n, t in group_techniques.items() if n != gname])
unique = techs - others
print(f"\nUnique to {gname}: {len(unique)} techniques")
Step 4: Detection Gap Analysis with Layer Overlay
# Define your current detection capabilities
detected_techniques = {
"T1059", "T1059.001", "T1071", "T1071.001", "T1566", "T1566.001",
"T1547", "T1547.001", "T1053", "T1053.005", "T1078", "T1027",
}
actor_techniques = set(technique_map.keys())
covered = actor_techniques.intersection(detected_techniques)
gaps = actor_techniques - detected_techniques
print(f"=== Detection Gap Analysis for APT29 ===")
print(f"Actor techniques: {len(actor_techniques)}")
print(f"Detected: {len(covered)} ({len(covered)/len(actor_techniques)*100:.0f}%)")
print(f"Gaps: {len(gaps)} ({len(gaps)/len(actor_techniques)*100:.0f}%)")
# Create gap layer (red = undetected, green = detected)
gap_techniques = []
for tech_id in actor_techniques:
info = technique_map.get(tech_id, {})
for tactic in info.get("tactics", [""]):
color = "#66ff66" if tech_id in detected_techniques else "#ff3333"
gap_techniques.append({
"techniqueID": tech_id,
"tactic": tactic,
"color": color,
"comment": f"{'DETECTED' if tech_id in detected_techniques else 'GAP'}: {info.get('name', '')}",
"enabled": True,
"score": 100 if tech_id in detected_techniques else 0,
})
gap_layer = {
"name": "APT29 Detection Gap Analysis",
"versions": {"attack": "16.1", "navigator": "5.1.0", "layer": "4.5"},
"domain": "enterprise-attack",
"description": "Green = detected, Red = gap",
"techniques": gap_techniques,
"gradient": {"colors": ["#ff3333", "#66ff66"], "minValue": 0, "maxValue": 100},
"legendItems": [
{"label": "Detected", "color": "#66ff66"},
{"label": "Detection Gap", "color": "#ff3333"},
],
}
with open("apt29_gap_layer.json", "w") as f:
json.dump(gap_layer, f, indent=2)
Step 5: Tactic Breakdown Analysis
from collections import defaultdict
tactic_breakdown = defaultdict(list)
for tech_id, info in technique_map.items():
for tactic in info["tactics"]:
tactic_breakdown[tactic].append({"id": tech_id, "name": info["name"]})
tactic_order = [
"reconnaissance", "resource-development", "initial-access",
"execution", "persistence", "privilege-escalation",
"defense-evasion", "credential-access", "discovery",
"lateral-movement", "collection", "command-and-control",
"exfiltration", "impact",
]
print("\n=== APT29 Tactic Breakdown ===")
for tactic in tactic_order:
techs = tactic_breakdown.get(tactic, [])
if techs:
print(f"\n{tactic.upper()} ({len(techs)} techniques):")
for t in techs:
print(f" {t['id']}: {t['name']}")
