What it detects

This rule detects the litellm_init.pth site-packages file and the p.py payload dropped by the trojanized LiteLLM PyPI releases 1.82.7 and 1.82.8 published by TeamPCP. The .pth mechanism forces arbitrary code execution during any Python interpreter startup so writing these files establishes a supply-chain backdoor that steals API keys SSH keys and cloud credentials.
