What it detects

This rule detects a shell command that pipes curl output into bash and detaches it with nohup, the initial execution used by a macOS ClickFix campaign to run an AppleScript stealer in the background after terminal closure. Fetching and executing a remote script in one detached command with no visible output is a strong indicator of ClickFix-style delivery on macOS.
