What Atomic Red Team does

Each atomic test describes one technique from MITRE ATT&CK, with prerequisites, the action to run and clean-up steps. Defenders run them in controlled environments to verify that the expected telemetry is collected and that alerts fire.

Tests can be run manually or through execution frameworks such as Invoke-AtomicRedTeam. Run them only on systems you control and agree on scope first.

Key features

  • Tests mapped to ATT&CK techniques
  • Windows, Linux, macOS and cloud tests
  • Prerequisites and clean-up steps
  • Execution frameworks for automation
  • YAML format for custom tests
