description: This rule flags Windows systems where a named pipe is created with a pipe name containing '\RemCom', matching the default RemCom pipe naming. Such named pipes are commonly used for inter-process communication that can support lateral movement or remote task execution via covert channels. The detection relies on telemetry that logs named pipe creation events, including the pipe name field.

  definition: Note that you have to configure logging for Named Pipe Events in Sysmon config (Event ID 17 and Event ID 18). The basic configuration is in popular sysmon configuration (https://github.com/SwiftOnSecurity/sysmon-config), but it is worth verifying. You can also use other repo, e.g. https://github.com/Neo23x0/sysmon-config, https://github.com/olafhartong/sysmon-modular. How to test detection? You can check powershell script from this site https://svch0st.medium.com/guide-to-named-pipes-and-hunting-for-cobalt-strike-pipes-dc46b2c5f575
