What it detects

This rule identifies registry writes to the AppCompatFlags TelemetryController area where the target command ends with "\Command" and the command details reference executable or script-like file extensions. Attackers can abuse the Windows telemetry workflow that uses CompatTelRunner.exe to execute extensible, registry-driven commands without restricting where the command resides. Detection relies on Sysmon-style registry_set telemetry capturing the TargetObject path and the Details content for the written values, with filtering to exclude specific system telemetry executables.
