title: Windows LogMeIn LMIGuardianSvc Execution Associated with Remote Access Tools
id: 8d47c82f-4796-467c-a3be-609c9c3ae068
status: test
description: This rule matches process creation events where the process metadata indicates the LogMeIn service "LMIGuardianSvc" (matched via Description, Product, and Company fields). Attackers may leverage legitimate remote access tooling to establish interactive control or support-like access within target networks, so unusual execution of vendor-branded components can be a useful signal. The detection relies on Windows process creation telemetry containing these process attribute fields.
