What it detects

This rule detects the Cleo Java runtime spawning Windows discovery utilities such as nltest, whoami, and ipconfig, the hands-on-keyboard reconnaissance seen after exploitation of Cleo file transfer software and the Malichus malware. A Java service process launching domain and host enumeration is not part of normal operation. This lineage indicates active post-exploitation of an internet-facing Cleo server.
