New USB Restricted Mode By Apple: iPhone’s latest security feature!

Mode By Apple: iPhone’s latest security feature

Apple quietly introduced a significant privacy safeguard as part of the new iOS 11.4.1 Restricted

on July 9th released that update.

USB Mode prevents USB accessories



that plug into the Lightning port from

making data connections with an iPhone, iPad, or iPod Touch if your iOS device has been

locked for over an hour.

This seemingly small change goes a long way in blocking tools used by law enforcement to

crack passcodes and circumvent Apple’s encryption and built-in measures designed to shield

sensitive user data.

What is THE iPhones USB Restricted Mode?

a new “security protection” introduced as part of iOS 11.4.1 Apple describes it as innovative.

The company hasn’t said as much,

iOS has built-in security features that prevent constant passcode guesses — such as when

it locks down your device after several incorrect attempts. But companies have seemingly

found a way of avoiding those safeguards via USB and the Lightning port.

Now, Apple is trying to eliminate this method of gaining entry to a recovered or confiscated device.

USB Restricted Mode works like this:

after an hour of your iPhone, iPad, or iPod

iOS  basically will cut off the Touch sitting & Lightning port  without being unlocked,  and


limit it to charging only.

This hour timeout should theoretically stop devices like GrayKey (which plugs into an

iPhone and cracks the passcode within a few hours) from working successfully.

“If you don’t first unlock your password-protected iOS device — or you haven’t unlocked

and connected it to a USB accessory within the past hour — your iOS device won’t

communicate with the accessory or computer, and in some cases, it might not

charge” reads Apple’s support page on the security feature.

USB Restricted Mode is enabled by default after the update

Once you’ve installed iOS 11.4.1, Apple automatically turns on USB Restricted Mode right away.

So you’ll need to unlock your iPhone or iPad to connect a USB accessory and get it working.



Accessories might not be able to charge your iPhone unless you unlock it first

 

iOS devices will charge normally when connected to a USB power adapter, but if you plug

in a gadget that normally delivers power over USB, you might have to unlock your iPhone or

iPad first before things work (and charge) like normal.

This is going to vary from the accessory to accessory.

It’s easy to turn off USB Restricted Mode

If you’re not concerned about someone potentially breaking their way into your iOS device,

you can disable the new security measure immediately.



Just go to Settings —> Face ID (or Touch ID) & Passcode —> USB Accessories.

Toggle this option to on (green) and your accessories will function the exact same way they

did before iOS 11.4.1.

Apple says this might be a good idea for people who use assistive devices with their iPhone,

iPad, or iPod Touch. “Many assistive devices will automatically turn on the setting to allow

USB devises the first time they’re connected,” says the company.

But if that doesn’t happen, disabling USB Restricted Mode just takes a quick visit to the



Settings menu.

USB Restricted Mode isn’t foolproof

Soon after the feature’s release, it was reported by iHackiT that plugging in a USB

an accessory like Apple’s own iOS camera adapter before USB Restricted Mode is activated

is enough to reset the 60-minute clock and prevent your iPhone from locking down its

Lightning port.

This is a workaround that Apple will likely patch sooner than later.
