How to protect your system

The government has advised users of Apple macOS Sonoma versions prior to 14.2.1 to be vigilant about any unusual system behaviour, unauthorised access attempts, or unexpected data disclosures. Any signs of abnormal activity should be treated as potential indicators of an ongoing exploitation attempt.

Most importantly, users are asked to prioritise updating their operating system to the latest version promptly to mitigate the risks associated with this vulnerability.

Additionally, here are some protection measures users are advised to take to keep their systems safe now and in the future from any such vulnerabilities.

• Update immediately: Apple has released a patch that addresses this vulnerability in macOS Monterey 12.7.1, macOS Ventura 13.2.1, and macOS Big Sur 11.7.4. Update your Mac to the latest version as soon as possible.
• Enable Automatic Updates: To streamline the update process and reduce the likelihood of overlooking crucial security patches, users are advised to enable automatic updates for their macOS system. This ensures that the latest security fixes are applied automatically, providing an additional layer of protection against potential threats.
• Regular System Monitoring: Users are also advised to actively monitor their systems for any unusual activities, unauthorised access attempts, or unexpected data disclosures.
• Enable firewall protection: To mitigate any possible harms, it is also asked to ensure your Mac's firewall is turned on to block unauthorised access attempts.
• Be cautious about suspicious links and applications: Avoid clicking on links or downloading applications from untrusted sources. This can help prevent attackers from tricking you into triggering the vulnerability.
• Back up Important Data: As a precautionary measure, users are also asked to regularly back up important data to an external and secure location. In the event of a security incident, having a recent backup ensures that critical information can be restored without significant loss.
