 ## Exploitation
 
-Machines with WMI enabled may be accessible to attackers if they come across the
-correct credentials. Infection Monkey's WMI exploiter uses brute-force to
-attempt to propagate to a victim via WMI.
+Attackers that can successfully authenticate to a machine via WMI can run
+arbitrary commands on the victim machine. This allows the attacker to perform
+actions such as installing malware, exfiltrating data, or pivoting and moving
+laterally through the network. Infection Monkey's WMI exploiter uses
+brute-force to attempt to propagate to a victim via WMI.
