What it detects

This rule detects a shell one-liner that curls an install script from the typosquatted homabrews domain and pipes it to bash, the ClickFix delivery behavior for Cuckoo Stealer on macOS. Adversaries leverage a fake Homebrew install command copied from a lure page to fetch and run the first-stage payload.
