iOS 11.4.1 has a new extremely important function for iPhone, iPad and iPod Touch, the Apple company implementing it to increase the security of the operating system it offers to its customers. We are talking about a new function in iOS 11.4.1 that limits access to the USB port of the iPhone, iPad and iPod Touch to one hour after the last unlocking, the function implemented by those from Apple having the name USB Accessories, USB accessories, it being also integrated in iOS 12.
Apple implemented this functionality in iOS 11.4.1 to prevent devices like Graykey from breaking the passcode of iPhone, iPad and iPod Touch to gain access to the data stored in the devices. The police and other similar government agencies use devices like this to jailbreak confiscated iDevices, but starting with iOS 11.4.1 their job will become much harder, because if the passcode brute force is not done within an hour of the last unlock, it would become impossible.
iOS 11.4.1: Very IMPORTANT New Feature
iOS 11.4.1 has this new security feature implemented by Apple as standard in all compatible iDevices, but the creators of Graykey claim that they have already found a method to overcome it and jailbreak iDevices. Of course, for now no proof has been published that this new function of iOS 11.4.1 has already become useless, but we will most likely see demonstrations of this kind in the next period, probably.
Apple released iOS 11.4.1 last night, so overnight it should have already been distributed through all of Cupertino's global servers, so it should be available for installation in iDevices at this time. If you do not need to jailbreak your iPhone, iPad, and iPod Touch, then there is no reason not to install iOS 11.4.1 on your devices, so I can only recommend that you install the update and leave this function active.
