Apple has released critical security updates for macOS Sonoma, Sequoia, and Tahoe to patch a screen-sharing vulnerability that allows unauthorized attackers to gain full control of user devices.

Key Points

• Apple patched a security flaw in macOS Sonoma 14.8.9, Sequoia 15.7.9, and Tahoe 26.6.1 that permits unauthorized screen-sharing access.
• The vulnerability allows attackers on the same network to bypass authentication, view private files, and control keyboard or mouse inputs.
• Researchers in the Netherlands identified that the exploit is currently being leveraged by hackers to facilitate unauthorized cryptocurrency mining.
• Users can mitigate immediate risks by disabling screen sharing in System Settings under the General and Sharing menus.

Why it Matters

This vulnerability poses a significant security risk because it grants attackers complete remote control over a compromised Mac without requiring valid credentials. Users should prioritize installing these updates immediately to prevent potential data theft, privacy breaches, and the unauthorized use of system resources for malicious activities.
