What it detects

This rule detects a command shell echoing data into a local named pipe, the service-based execution pattern produced by the Metasploit PsExec module when it installs a service that writes command output back through a pipe. This is used for remote code execution and lateral movement from a compromised host. Legitimate software does not echo into a raw named pipe from cmd.exe in this way.
