Description
The following analytic detects the use of WMIC (Windows Management Instrumentation Command-line) for reconnaissance and system information discovery on Windows endpoints. It identifies command-line queries targeting common Win32 WMI classes such as Win32_OperatingSystem, Win32_Processor, csproduct, Win32_DiskDrive, and Win32_PhysicalMemory, which are frequently leveraged to enumerate hardware, operating system details, and system configuration. Adversaries often use these queries during post-exploitation to fingerprint hosts, assess virtualization, and tailor follow-on activity. While WMIC usage can be legitimate for administrative and inventory tasks, suspicious or unexpected execution—particularly by non-administrative users or uncommon parent processes—may indicate malicious reconnaissance aligned with system discovery techniques.
