What it detects

This rule flags Windows processes where systeminfo.exe is executed, including cases where the OriginalFileName is sysinfo.exe. Attackers may run system discovery commands to enumerate host and environment details before further actions. It relies on process creation telemetry, matching the executed image path ending with \systeminfo.exe or the reported original filename.
