What it detects

This rule matches process creation for TeamViewer’s desktop executable when it is started via the TeamViewer service and uses a specific IPC port and module argument. Attackers can use remote access tooling like TeamViewer to establish interactive access from a remote host, so correlating this startup command helps identify remote session initiation. It relies on Windows process creation telemetry, specifically the executable path, parent process image, and the command line ending pattern.
