What it detects

This rule detects osascript invoking a display dialog that requests a password with hidden input on macOS. The AMOS stealer shows a fake system password prompt through osascript to harvest the user credential before dumping keychain and wallet data, so this dialog pattern indicates credential phishing by the stealer.
