What it detects

This rule detects a shell downloading and executing an installer script hosted on a HuggingFace Space on Linux hosts. The marimo blockchain botnet campaign delivered the kagent NKN based remote access trojan through an install-linux.sh script pulled from a HuggingFace Space domain. Piping a remote Space installer into a shell indicates malware delivery.
