Description

The following analytic detects the execution of `powershell.exe` with command-line arguments that utilize the `Get-WmiObject` cmdlet and the `Win32_UserAccount` parameter to query local user accounts. It leverages data from Endpoint Detection and Response (EDR) agents, focusing on process names and command-line executions. This activity is significant as it may indicate an attempt by adversaries to enumerate user accounts for situational awareness or Active Directory discovery. If confirmed malicious, this behavior could lead to further reconnaissance, privilege escalation, or lateral movement within the network.
