What it detects

This rule detects a Python interpreter running a script located under /var/root/Library/Caches/ on macOS. The crypto-stealing backdoor stages its Python payload as /var/root/Library/Caches/<uuid>.py and executes it with elevated privileges, so this execution path indicates the hidden backdoor script running as root.
