Improvix Teammates,


In case you haven’t already heard, Apple released iOS/iPadOS version 14.4 on January 26th to address multiple high-risk security concerns. In an effort to protect your personal and any company data held on your Apple mobile devices, we strongly advise you to upgrade your iPhones, iPads, and iPods as soon as possible.


What Is the Security Risk?


Apple has disclosed that any iOS/iPadOS devices on a version below the newly-released 14.4 are vulnerable to remote access by malicious actors. Specifically, there are two vulnerabilities. One vulnerability stems from “WebKit”—a web-browser rendering engine—allowing hackers to remotely control devices through your web browser. The second vulnerability stems from a kernel (operating system) vulnerability allowing hackers to elevate user privileges to perform subsequent detrimental actions, using apps downloaded from the App Store as the attack vector.


How Do I Address the Risk?


To mitigate your risk exposure, ensure your iPhone, iPad, and/or iPod is running at least iOS/iPadOS version 14.4. To check the version of your iOS/iPadOS device, follow these steps:

  1. Open the “Settings” app
  2. Select the “General” tab
  3. Select the “About” tab
  4. Note the value listed next to the “Software Version” field towards the top (e.g., 14.4).


If your device is on a version below 14.4, follow these steps to initiate the upgrade:

  1. Open the “Settings” app
  2. Select the “General” tab
  3. Select the “Software Update” tab
  4. Select “Download,” then “Install Now.”


Note that you will need to be connected to Wi-Fi to download the update, and either be connected to your charger or have at least 50% battery available.
