Attackers Could Take Over Your Mac Through Screen Sharing Unless You Update Now
Apple issued a fix for the vulnerability. But it’s best to disable screen sharing when not actively using it.
Mac users who have not yet updated their operating system are at risk of a significant screen-sharing vulnerability, according to Dutch researchers. This exploit, which has already been employed for cryptocurrency mining, could grant attackers full control of a Mac via the screen-sharing function. This feature allows for the wireless mirroring or extension of a Mac's desktop to other devices.
The vulnerability could enable an attacker to gain unauthorized access to a screen sharing session, view private files, monitor private conversations, and even take control of the user's keyboard, mouse, or trackpad. This could occur either during an active screen sharing session or if the feature is left enabled without disconnecting.
Users can mitigate this risk by updating to the latest MacOS versions (Sonoma 14.8.9, Sequoia 15.7.9, and Tahoe 26.6.1). These updates include security patches to address the vulnerability. To check if this vulnerability affects your system, navigate to Mac OS system settings under General, then Sharing. Apple has not yet responded to a request for comment.
