## What it does

This skill queries ATT&CK group and technique data with `attackcti`, then builds technique maps with tactics, platforms, and data sources. It can compare several APT groups, create MITRE ATT&CK Navigator layers, and overlay them against detection coverage.

The included Python workflow covers group lookup, Navigator layer JSON generation, and multi-group technique comparison. It requires Python 3.9+ with `attackcti`, `mitreattack-python`, `stix2`, and `requests`, plus MITRE ATT&CK Navigator or a local deployment. Threat-intelligence reports or MISP/OpenCTI access are also listed as prerequisites. Check the Python environment and data source first.

Layers can hold technique scores, colors, comments, and metadata for the Enterprise ATT&CK matrix. The output supports detection-gap analysis, threat hunting, and threat-intelligence reporting.

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/mukul975/Anthropic-Cybersecurity-Skills/tree/HEAD/skills/analyzing-apt-group-with-mitre-navigator/SKILL.md

## When to use it
- look up ATT&CK techniques used by an APT group
- generate a JSON layer for MITRE ATT&CK Navigator
- compare TTPs across several groups
- map group techniques against detection coverage
- prepare data for a threat-intelligence report

## Example prompts
- Analyze APT29 with ATT&CK and save the technique map as `apt29_layer.json`.
- Compare APT29, APT28, and Lazarus Group, then identify their shared techniques.
- Build a MITRE ATT&CK Navigator layer for this group with tactics, platforms, and comments.

# 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
