What it detects

This rule detects creation of an __init__.py file inside the user Public directory, the drop location used by Slow Pisces to stage its RN Loader Python payload during fake coding-challenge lures. Planting a Python package init file in this path enables execution of the malicious loader when the developer runs the challenge code.
