InfoSec Alert: Critical Security Updates for Apple Devices (iOS, macOS)

Apple recently released a critical software update for all iOS (iPhones and iPads) and macOS devices designated iOS 15.6.1 and macOS 12.5.1. With the launch of these updates, Apple took the increasingly common step of alerting users that these updates patch vulnerabilities that criminals may actively exploit. Please update your iOS and macOS devices as soon as possible to ensure you are protected.

How to Update

  • iPhone/iPad: Open the “Settings” app, then select General>Software Update to be sure that your device is running the newest version of iOS (15.6.1).
  • macOS: Open “System Preferences,” then navigate to “Software Update,” then follow the directions on the next screen to update to macOS Monterey 12.5.1.

The relevant exploits appear to involve WebKit and the Kernel, which are essential for web-browsing capabilities and the operating system. All users should immediately update their devices to the latest versions to avoid data loss and additional vulnerabilities.
