Get-AdComputer with PowerShell

The analytic detects the execution of `powershell.exe` with the `Get-AdComputer` commandlet, which is used to discover remote systems within a domain. This activity indicates potential reconnaissance efforts by adversaries to map out domain computers, which is a common step in the attack lifecycle. If confirmed malicious, this behavior could allow attackers to gain situational awareness and plan further attacks, potentially leading to unauthorized access and data exfiltration.
