A sophisticated macOS malware campaign leverages ClickFix social engineering to infect victims. The attack begins with a fake CAPTCHA prompt delivered via email links, tricking users into executing malicious commands in Terminal. This downloads a profiling script that collects system information and deploys architecture-specific Go-based Mach-O payloads. The stealer targets browser passwords, Apple Keychain credentials, and cryptocurrency wallets. Its most notable feature is a DRAIN function that gradually siphons cryptocurrency from victims' wallets by redirecting portions to attacker-controlled accounts. The malware supports Bitcoin, Litecoin, Dogecoin, Monero, Ethereum, and XRP. Infrastructure analysis reveals hosting through Aeza Group, a sanctioned Russian bulletproof hosting provider. The malware achieves persistence through macOS Background Task Management and uses various evasion techniques including Gatekeeper bypass and credential harvesting via fake system prompts.
