description: This rule identifies process executions of the WMIC command-line utility (wmic.exe) where specific system discovery queries are issued. The matched commands enumerate operating system details, disk drive names and capacity, and other system attributes, which can support reconnaissance and environment profiling. Telemetry relies on Windows process creation fields including the original executable metadata and command-line contents.
