What it detects

This rule flags registry activity involving the Provisioning Commands path under \\SOFTWARE\\Microsoft\\Provisioning\\Commands\\. Attackers can misuse this area to redirect execution through a proxy-style binary such as Provlaunch.exe, helping them run code indirectly while blending into legitimate provisioning mechanisms. The detection relies on registry-set telemetry that includes the TargetObject field containing the monitored registry path.
