+- name: Enumerate domain computers within Active Directory using DirectorySearcher
+  description: |
+    This test is a Powershell script that enumerates Active Directory to determine computers that are joined to the domain. 
+    This test is designed to mimic how SessionGopher can determine the additional systems within a domain, which has been used before by threat actors to aid in lateral movement. 
+    Reference: [Head Fake: Tackling Disruptive Ransomware Attacks](https://www.mandiant.com/resources/head-fake-tackling-disruptive-ransomware-attacks). 
+    Upon successful execution, this test will output the names of the computers that reside on the domain to the console window.
