Testing Against APT Techniques

Advanced Persistent Threats (APTs) use sophisticated techniques that require comprehensive detection coverage. Atomic Red Team enables testing against these real-world attack patterns.

Dragon Tail Campaign

This post focuses on testing detection coverage for techniques observed in APT campaigns, specifically:

  • Initial access methods
  • Persistence mechanisms
  • Credential access
  • Lateral movement
  • Data exfiltration

Test Methodology

Map Campaign to ATT&CK

Identify specific techniques used in the campaign.

Select Atomic Tests

Choose tests that match observed techniques.

Execute Tests

Run tests in controlled environment.

Validate Detection

Confirm your security controls detected the activity.

Coverage Gaps

Testing often reveals:

  • Missing detection rules
  • Insufficient telemetry
  • Configuration issues
  • Tool limitations

Continuous Validation

APT techniques evolve. Regular testing ensures:

  • Detection coverage remains effective
  • New techniques are covered
  • Existing detections still work
  • Team skills stay sharp

Building Detection Coverage

For each technique:

  1. Understand the technique
  2. Identify telemetry sources
  3. Write detection logic
  4. Test with Atomic Red Team
  5. Tune for false positives
  6. Document coverage
