Apple's iOS 14.4 update is now live - and as well as plugging a security hole, it will help with Covid-19 poster scanning.
Late yesterday Crown agency CERT NZ (the Computer Emergency Response Team) issued an advisory about a security vulnerability with iOS that Apple says is being actively exploited by hackers.
The issue relates to iOS (the software that runs iPhones), iPadOs and tvOS (the software that runs Apple TVs).
"Immediately update your Apple iOS, iPadOS and tvOS devices to version 14.4 where the update is available. For most users, a pop-up should alert you that an update is available – select 'Update Now'," CERT NZ's advisory said.
