What it detects
This rule flags process executions where the process image path ends with /shutdown, /reboot, or /halt on macOS. Attackers can use system restarts or shutdowns to disrupt access to a target host and hinder incident response, or as part of broader impact activities. Telemetry relies on process creation data that includes the executing image path.
