iOS 11.4.1 adds USB restricted mode, here is what it means

Apple has added a new security feature called USB restricted mode to iOS 11.4.1 that makes it harder for hackers – as well as law enforcement and government agencies – to unlock your iPhone. Here’s how to enable this feature. The new feature prevents USB accessories from connecting to the iOS device if the device has been locked for more than an hour.

The restricted mode was created to protect iPhones against USB devices used by law enforcement to crack your passcode and get around encryption. It disables USB access after the phone has been locked for an hour, instead of a week as was previously the rule. To see the new mode toggle, drop into your Settings app and look under Touch ID (or Face ID if you have an iPhone X). There will be a new toggle button for USB Accessories there. Access is already disabled by default, so toggling it on with a tap will allow access for USB accessories.

How to turn on USB Restricted Mode on your iPhone or iPad?

  1. First of all update to the latest firmware iOS 11.4.1.
  2. Tap on Settings > Touch ID & Passcode (or on the iPhone X Face ID)
  3. Enter your device’s passcode.
  4. Tap the switch next to USB Accessories under Allow Access When Locked to put it in the white “off” position (if it’s not there already) if you want USB Restricted Mode activated. If it’s in the green “on” position, USB devices will have the same level of access that they’ve previously had.

Recently, we’ve seen the emergence of a number of devices, including the GrayBox, that allow third parties to gather data from your iPhone or iPad through the Lightning port without having to unlock your device beforehand. While these devices are specially designed for law enforcement, they are still taking advantage of a security hole that anyone could theoretically exploit.

Hopefully, this new update can fix these things up making iPhones more secure than any other cell phones present in the market.
