macOS ClickFix campaign uses browser fingerprinting
🛡️ Microsoft tracked a macOS ClickFix operation using over 250 front-end domains that fingerprint visitors before deciding whether to show a malware lure. The server-side gate hides malicious pages from crawlers and sandboxes while showing selected Mac users a fake download that ultimately retrieves scripts to launch infostealers such as MacSync and Atomic Stealer (AMOS). The attack still requires users to paste and run an obfuscated Terminal command, and Microsoft recommends users never paste browser instructions into Terminal.
