status: test
description: This rule identifies execution of the SharPersist Windows tool by matching the process image name (SharPersist.exe) and specific command-line patterns used to configure persistence. An attacker can leverage SharPersist to deploy multiple persistence mechanisms such as scheduled tasks, startup folder entries, registry run keys, and services. Detection relies on Windows process creation telemetry, including the full image path and command-line arguments.
