A major security flaw has been discovered in macOS that can be exploited by hackers to install malware. This vulnerability has been dubbed “Achilles” and was first found in July 2022. Apple patched this vulnerability earlier this December (which is why we’re now hearing about it) but your Apple products could still be in danger. You should approve the latest Mac update on your Macbook, iMac, Mac mini, or any other Apple computer you may have as soon as possible. Hackers like to target vulnerable machines, so the sooner you update the better.

About “Achilles”

Apple includes Gatekeeper and XProtect in every version of macOS. Gatekeeper ensures all new software is verified before it’s installed, while XProtect scans for malware. The Achilles flaw was abusing a logic issue in Gatekeeper’s security protections, allowing malicious apps to be installed on Macs. The latest version of macOS fixes this vulnerability and should be installed as soon as possible. You may also want to consider installing a well-rated Mac antivirus software as an additional measure.

While this “Achilles” flaw is resolved through the latest update, hackers will continue to look for ways to exploit operating systems. For more information on cyber threats or if you have any general IT questions, feel free to reach out to us at
