As soon as put in on the person’s Mac, the malware is designed to root our and steal credentials from Arc, Courageous, Firefox, Google Chrome and Microsoft Edge browsers, once more highlighting the vulnerability in saving passwords in browsers.
Past that, completely different malware payloads could be tasked with completely different outcomes.
