performing-threat-emulation-with-atomic-red-team
Executes Atomic Red Team tests for MITRE ATT&CK technique validation using the atomic-operator Python framework. Loads test definitions from YAML atomics, runs attack simulations, and validates detection coverage. Use when testing SIEM detection rules, validating EDR coverage, or conducting purple team exercises.
What this skill does
# Performing Threat Emulation with Atomic Red Team
## Instructions
Use atomic-operator to execute Atomic Red Team tests and validate detection coverage
against MITRE ATT&CK techniques.
```python
from atomic_operator import AtomicOperator
operator = AtomicOperator()
# Run a specific technique test
operator.run(
technique="T1059.001", # PowerShell execution
atomics_path="./atomic-red-team/atomics",
)
```
Key workflow:
1. Clone the atomic-red-team repository for test definitions
2. Select ATT&CK techniques matching your detection rules
3. Execute atomic tests using atomic-operator
4. Check SIEM/EDR for corresponding alerts
5. Document detection gaps and update rules
## Examples
```python
# Parse atomic test YAML definitions
import yaml
with open("atomics/T1059.001/T1059.001.yaml") as f:
tests = yaml.safe_load(f)
for test in tests.get("atomic_tests", []):
print(f"Test: {test['name']}")
print(f" Platforms: {test.get('supported_platforms', [])}")
```
