This report highlights Acer’s signed RunCmd utility as a living-off-the-land binary that can execute commands or scripts silently (default behavior or via the /F flag), enabling stealthy execution without an obvious parent process. It provides MD5 hashes for both 64-bit and 32-bit versions, describes expected logging behavior (RunCmdLog folder and timestamped logs), and offers defensive insights for detection, making it relevant for both offensive and defensive operations.
