What it detects

This rule detects use of the Powermad New-MachineAccount cmdlet to create a rogue computer account in Active Directory, the first step of a resource-based constrained delegation attack that leads to privilege escalation. Creation of attacker-controlled machine accounts through this tooling is a strong indicator of an RBCD abuse chain.
