What it detects

This rule detects creation of a named pipe called REDSUN, a hardcoded inter-process channel used by Nightmare-Eclipse tooling observed in a real-world Huntress intrusion. The agent relies on this fixed pipe name for command relay between its components. Because the pipe name is a distinctive tool-specific constant, its presence is a high-confidence indicator of the framework.
