What it detects

This rule detects creation of the litellm_init.pth Python path-configuration file. The LiteLLM supply-chain attack abused a .pth file that Python auto-executes at interpreter startup to run attacker code whenever the environment is used as documented by Kaspersky. A malicious .pth dropped into a site-packages directory grants stealthy persistence tied to every Python invocation.
