What it detects

This rule flags Windows named pipe creation events where the PipeName contains the specific substring "\coerced\". Such naming patterns can indicate usage of tools or behaviors associated with coercion-based privilege escalation and related stealth techniques. It relies on telemetry from Windows named pipe creation logging, such as Sysmon named pipe event monitoring.

  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
