Detects the execution of suspicious child processes (shells, interpreters, or system reconnaissance tools) directly spawned by critical Citrix NetScaler service binaries (nsppe, httpd, nsaaad). This behavior is indicative of post-exploitation activity, such as command injection or lateral movement following the exploitation of a public-facing NetScaler application vulnerability.
