The iOS 16.3.1 update is available for the iPhone 8 and later, iPad Pro (all models), iPad Air 3rd generation and later, iPad 5th generation and later, and iPad mini 5th generation and later. The iOS 16 upgrade also comes with some brilliant new iPhone features, many of which are a boost to your security.

While Apple had previously been updating iOS 15 with important security fixes, it is only doing so for older iPhones that can’t upgrade to iOS 16. If you are on iOS 15 but have an iOS 16-compatible iPhone, now may be the time to update to iOS 16.3.1. However, there’s no reason to believe this has happened in real-life attacks yet, Wright adds. “It’s also theoretically possible to chain the WebKit vulnerability with the Kernel one to gain full access to the device,” he warns.

Updating to iOS 16.3.1 as soon as you can is the best way to protect yourself, says independent security researcher Sean Wright. The stakes are even higher for businesses and high-profile individuals. While the exploited bug probably targets a specific group of people, it’s only a matter of time before more attackers use it more widely. If you are already on iOS 16, you need to update to iOS 16.3.1.
