Windows Process Creation: Suspicious systeminfo.exe Execution

title: "Windows Process Creation: Suspicious systeminfo.exe Execution"
id: 88aaef2c-05cc-4d02-8714-a92ae8d50063
status: test
description: 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.
