What it detects

This rule detects reg.exe saving the SAM, SYSTEM or SECURITY registry hive to disk, which lets an attacker extract local credential material and boot keys for offline hash recovery. Registry hive dumping is a credential-access technique documented in the Red Canary Threat Detection Report. Detecting these save commands surfaces local credential theft in progress.
