+- name: Skeleton Key via Mimikatz
+  description: |
+    Injects a Skeleton Key into LSASS on a domain controller using Mimikatz. Once injected, any domain
+    user account can be authenticated using the password 'mimikatz' until the domain controller is rebooted.
+
+    This test must be run on an isolated domain controller and must not be performed on a production DC.
+    Cleanup forces a reboot of the domain controller to evict the skeleton key from LSASS memory.
