SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires atomic-operator, pyyaml.

What problem does it solve?

Security teams often deploy SIEM and EDR detection rules without knowing whether they actually fire against real attack techniques. This Skill runs Atomic Red Team tests mapped to MITRE ATT&CK techniques so you can verify detection coverage and identify gaps before attackers do.

Core Features & Use Cases

  • Atomic Test Execution: Runs attack simulations for specific ATT&CK techniques (e.g., T1059.001 PowerShell execution) using the atomic-operator Python framework.
  • YAML Atomic Parsing: Loads and inspects Atomic Red Team YAML test definitions to review supported platforms and test details before execution.
  • Detection Validation Workflow: Guides a five-step process from cloning the atomic-red-team repository through checking SIEM/EDR alerts and documenting detection gaps.
  • Use Case: During a purple team exercise, run atomic tests for the techniques your new detection rules target, confirm alerts appear in your SIEM, and update rules where coverage is missing.

Quick Start

Run the Atomic Red Team test for MITRE ATT&CK technique T1059.001 and check whether my SIEM generates a corresponding alert.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I run Atomic Red Team tests with Python?▼

Use the atomic-operator Python framework: instantiate AtomicOperator and call run() with a technique ID like T1059.001 and the path to your atomics directory. The framework loads the YAML test definitions and executes the attack simulation.

How to validate SIEM detection rules against MITRE ATT&CK?▼

Select ATT&CK techniques matching your detection rules, execute the corresponding Atomic Red Team tests with atomic-operator, then check your SIEM or EDR for alerts. Document any techniques that produced no alert as detection gaps.

What Python version does atomic-operator require?▼

The workflow requires Python 3.8 or later with the atomic-operator package installed. You also need to clone the atomic-red-team repository to supply the YAML atomics test definitions.

Can I inspect atomic test definitions before running them?▼

Yes. Atomic tests are YAML files you can parse with PyYAML to review each test's name and supported_platforms before execution. This helps confirm the test matches your target operating system.

Is it safe to run Atomic Red Team tests in production?▼

Atomic tests execute real attack techniques, so they should run in a test or lab environment with proper authorization. The Skill explicitly requires a safe environment and appropriate authorization before any testing activity.
