CMD Echo Pipe - Escalation

splApache-2.0from splunk/security_content

The following analytic identifies the use of named-pipe impersonation for privilege escalation, commonly associated with Cobalt Strike and similar frameworks. It detects command-line executions where `cmd.exe` uses `echo` to write to a named pipe, such as `cmd.exe /c echo 4sgryt3436 > \\.\Pipe\5erg53`. This detection leverages data from Endpoint Detection and Response (EDR) agents, focusing on process and command-line telemetry. This activity is significant as it indicates potential privilege escalation attempts. If confirmed malicious, attackers could gain elevated privileges, enabling further compromise and persistence within the environment.
