Mac Malware Found Draining Crypto Wallets After Fake CAPTCHA Trick

Huntress researchers have uncovered a macOS malware strain that uses a fake CAPTCHA (ClickFix) trick to get victims to paste a malicious command into Terminal. Once executed, a Bash loader fetches a Go-based payload that harvests Apple Keychain credentials, browser passwords, and cookies. Its standout feature is a DRAIN function that incrementally siphons cryptocurrency wallet funds — covering Bitcoin, Litecoin, Dogecoin, Ethereum, and XRP — rather than emptying wallets all at once to avoid detection. The malware also tricks victims into re-entering their system password via a fake dialog box. Infrastructure was traced to Aeza Group, a sanctioned Russian bulletproof hosting provider. Huntress recommends treating ClickFix prompts as red flags, training staff not to paste unknown terminal commands, and using browser extensions and DNS-level blocking as defenses.
