What it detects
This rule detects osascript invoking an AppleScript display dialog that requests a password, the credential-harvesting behavior Red Canary tied to Atomic Stealer and related macOS malware. Legitimate applications rarely prompt for a password through scripted dialogs, so this combination indicates an attempt to socially engineer the user into revealing local credentials.
