Apple will make iPhones harder to hack with iOS 11.4

INSUBCONTINENT EXCLUSIVE:
While it might be necessary for authorities to access data stored on handsets for criminal investigations, Apple has, historically, refused
to cooperate when approached
This should, ideally, prevent data stored on the device from being harvested when plugged into a computer via a USB-to-Lightning cable.The
new feature has been tested by security software company Elcomsoft and it has been confirmed that if an iPhone or iPad running iOS 11.4
on an Apple device during an investigation, they will have precisely seven days to do so, using tools like GrayKey
Restricted Mode was first introduced in an early beta version of iOS 11.3, but was removed from the final release.
