title: Windows process command lines matching May 2020 Turla ComRAT command patterns
id: f49e44bd-4f4e-4983-a05b-98debe43c96f
status: test
description: This rule identifies Windows process creations where the command line matches specific Turla group ComRAT-related command patterns described in the referenced ESET report. Attackers may use these command invocations to execute follow-on actions, including execution and persistence techniques. It relies on process creation telemetry with command-line data and matches either exact substrings or a defined regular expression pattern in the CommandLine field.
