Remote Registry Save (Credential Dumping)
Detects inbound RPC calls to the Windows Remote Registry interface using operation numbers associated with registry save/backup operations, which may indicate credential dumping via remote registry access. This rule specifically looks for RPC UUID '338cd001-2244-31f1-aaaa-900038001003' and operation numbers 20 or 31, which correspond to registry save/backup functions.
