Hackers Exploit macOS Security Features to Spread Malware

A growing wave of sophisticated attacks is turning macOS’s built-in security defenses into avenues for malware distribution, according to recent security research.

As macOS continues to gain market share, cybercriminals are adapting their strategies to exploit even the most robust Apple protections. Analysts warn that relying solely on native safeguards may leave organizations vulnerable to novel bypass techniques.

macOS employs a layered security model—including Keychain, Transparency, Consent and Control (TCC), System Integrity Protection (SIP), File Quarantine, Gatekeeper, XProtect and XProtect Remediator—to safeguard user data and system files.

Researchers have documented how attackers are subverting these controls with custom utilities and social engineering, effectively weaponizing Apple’s own tools.

Keychain, the operating system’s password manager, encrypts credentials using AES-256-GCM and enforces file access restrictions.

Yet specialized tools like “Chainbreaker” can decrypt local Keychain files if an adversary gains physical or administrative access ...
