Over the past few years, we have seen a confrontation between the FBI and Apple to get the company to allow them access to blocked mobile devices. To further enhance the security of iOS, Apple has just released an update that prevents unauthorized access via USB, preventing them from accessing our iPhone content via this connection.
Specifically, the feature we talked about has been available for just a few hours, so we recommend that you upgrade your device to iOS 11.4.1 to start taking full advantage of its potential. Once installed, the function will lock the cable data transmission when one hour has passed without the device being unlocked.
This means that as long as you do not use Face ID, Touch ID or the unlock code for an hour, data transmission via USB is completely disabled. Apple’s goal with this measure is not only to prevent them from accessing our data from a computer but also to prevent the use of hardware specifically designed to extract private data from mobile devices, which underscores the importance of the update.
In particular, the “USB accessories” function is available under Settings – Face ID and code (or Touch ID and code) – USB accessories. As you will see from your devices, the option is disabled by default, and this is exactly what we want to make it work as described in the article.
