If you’ve not yet updated your iPhones, iPads, and Macs with the latest patches from Apple, then you need to take some time out of your day to do it right now, because this is a big one. Apple just published the iOS 14.7.1, iPadOS 14.7.1, and macOS Big Sur 11.5.1. While this update contains bug fixes, the main part of this update is a security fix for a vulnerability that Apple says, “may have been actively exploited” which means attackers are already using it. The vulnerability is described as a memory corruption issue which enables attackers to execute an arbitrary code onto your devices with kernel privileges. It’s unclear if this is the vulnerability used for jailbreaking iOS devices, or whether it is linked to the NSO Group spyware tool hack used to target journalists, activists, and government figures. Regardless, to be safe and keep your devices protected you should carry out these updates as soon as possible.
