What it detects

This rule detects a terminal one-liner that base64-decodes an embedded payload and pipes it into a shell, the macOS ClickFix execution behavior tricking users into pasting commands into Terminal. Adversaries leverage inline base64 decoding to hide the downloader and run it without writing an obvious script to disk.
