The update was supposed to fix some bugs, but instead, there was a security vulnerability.
Apple released new update iOS 11.4.1, whose main task was to fix bugs in iOS 11. However, experts found serious vulnerability in security. About it writes The Verge.
It is known that the new version of the OS contains a system of protection against password guessing USB Restricted Mode. For this, the system has restricted the use of USB devices: blocked for more than an hour, the gadget via the Lightning can only be charged and other functions of the connector will become unavailable until the next unlock.
This creates difficulties when using special devices involved in the selection of the password when connecting to the Lightning connector. However, it turned out that in iOS 11.4.1 this system can be circumvented.
Security experts ElcomSoft has found a vulnerability with which you can outwit hour limit on the USB connector. You will need to connect to a smartphone or tablet of any accessory Apple until the moment when the system will go into protected mode USB Mode Restricted.
For this purpose it is possible to use, in particular, the adapter Apple Lightning-to-USB. However, an adapter for 3.5 mm earphone Jack for this purpose is not appropriate.
Later, after connecting a “trusted” accessory, can connect to the gadgets and those that find the passwords.
Earlier it was reported that Apple released a public beta version of the iOS operating system 12.
