Slow Fog: The macOS malware "MacSync Stealer" is active and highly destructive

According to monitoring by the blockchain security firm SlowMist, MistEye has received threat intelligence from the community indicating that a malware named "MacSync Stealer" (v1.1.2) is active and highly destructive. This malware targets macOS users, stealing sensitive data including cryptocurrency wallets, browser credentials, system keychains, and infrastructure keys (SSH/AWS/K8s).

The malware uses a spoofed AppleScript system dialog for phishing and displays fake error messages stating "unsupported" after data leakage. It has immediately synchronized this IOC (Indicator of Compromise) to clients. Do not execute unverified macOS scripts and remain highly vigilant against unexpected system password prompts. If an attack is suspected, immediate remediation is required: change all infrastructure credentials (SSH/AWS/K8s), invalidate any exposed keychains, and quickly migrate cryptocurrency assets to a secure wallet.
