What it detects

This rule detects download utilities piping fetched content directly into a shell interpreter, the loader pattern the agentic container-escape actor used to stage its second-stage payload from an attacker server. Piping remote content into sh or bash executes untrusted code without touching disk. This is a common ingress tool transfer and execution technique.
