What it detects

This rule matches Linux process creation events where TeamViewer Desktop is launched with an IPC port and module arguments as part of a remote session startup. Attackers can use remote access tooling to establish interactive control, so identifying these session-init command lines helps surface remote access activity. Telemetry relies on process execution details, specifically the parent process path ending with TeamViewer_Service, the TeamViewer Desktop binary path, and the exact command-line suffix containing the IPC port and module.
