As it stands right now law enforcement has a few tools that it uses to gain access to these devices whether the owner wants to unlock them or is even alive to unlock them.
Apple's description of the feature indicates a workaround.
Police and forensics officials in the United States are understood to be using a piece of hardware. In both cases, an iPhone or iPad might not be unlocked, whether through passcode or biometrics, for days.
Phnom Penh Post sold and editor-in-chief sacked
The Post itself had owed $3.9 million in taxes, but that bill was settled as part of the sale, The Post reported. Intervention in the paper's editorial decision-making came nearly immediately after the sale was announced.
Apple mentioned that it has taken the initiative to improve security in its iOS devices. Once an iPhone or iPad is updated to the latest version of iOS that supports the feature, the USB data connection over the Lightning port is disabled one week after the phone was last unlocked. After seven days of inactivity, USB Restricted Mode prevents the port from being used to do anything except charge the device. Until then, Apple users can at least rest assured that their devices are a bit more secure from intrusion in iOS 11.4 than they were before.
With USB Restricted Mode enabled, the iDevice can no longer be paired to computers or accessories, without entering the correct passcode or Touch ID / Face ID biometric. It notes that this feature was originally introduced in early iOS 11.3 betas, but was later removed in the final release. This testing showcased that data transfers are blocked after seven days without unlocking a device. This basically locks the device in a way that it can not be restored or updated via iTunes after the threshold period is met. You can also try to delete the faulty message from another iOS device linked to the same iCloud account. However, for a law enforcement agents, this will be a nightmare. To increase device security, iOS 11 made the lockdown records expire after an unspecified period of time, while iOS 11.3 clamped down further, causing the records to expire after seven days.
