Last week it was discovered that there was a Vulnerability in iOS 11’s HomeKit, in which apparently when exploited, it would allow the hacker to gain control of HomeKit-connected devices. Apple then made some changes server-side that temporarily patched the vulnerability while a proper fix was expected to arrive at a later date.
For those who do own a fair bit of HomeKit-connected devices, you’ll be pleased to learn that Apple has since released iOS 11.2.1. This update to iOS 11 is meant to address the Homekit Vulnerability. Like we said, when the issue first came to light, Apple issued a server-side fix that blocked remote access of the Home app for shared users.
