+name: Suspicious child spawned via reflected process
+id: 0c71dd48-d238-41bb-9c7e-9ba804e888de
+version: 1.0.0
+description: |
+  Identifies the creation of a child via the clone process by employing the
+  RtlCreateProcessReflection or RtlCloneUserProcess API.
+  This behaviour represents a potential Dirty Vanity process injection.
