What it detects

This rule flags registry changes where the UpdateRingSettingURLFromOC path is set to a value that contains the OneDriveStandaloneUpdater.exe update URL-from-OC setting. Attackers can use this mechanism to redirect an update component to download attacker-controlled content without directly launching suspicious executables. It relies on Windows registry set telemetry capturing updates to the specified SOFTWARE\Microsoft\OneDrive\UpdateOfficeConfig\UpdateRingSettingURLFromOC key.
