What it detects

This rule detects DNS lookups for the checkmarx.zone and models.litellm.cloud command-and-control hosts used by the trojanized LiteLLM PyPI packages to exfiltrate harvested environment variables and cloud credentials. A resolution of either host on a build or developer machine indicates the malicious LiteLLM payload has executed and is calling home.
