    Fake CAPTCHA Terminal commands deliver Atomic macOS Stealer on Mac devices

    Initial Disclosure

    Palo Alto Networks Unit 42 identified a macOS ClickFix campaign that uses fake CAPTCHA pages and Terminal commands to quietly download, mount, and launch malicious DMG payloads on Mac devices. The campaign delivers Atomic macOS Stealer (AMOS), which steals browser credentials, cryptocurrency wallet data, Keychain data, messaging app information, and user documents, and it uses a download-and-launch chain that hides the DMG mount and then uploads harvested data to attacker infrastructure.
