A device for the selection of pin codes for iPhone

English security experts have discovered on sale tricky device IP-BOX for brute force pin codes iPhone. It costs £ 200, and its feature is the ability to bypass the restriction in settings for 10 input attempts. If you enable this option, then after 10 incorrect attempts, the smartphone usually overwrites the memory. But not in this case.

The trick is an unusual device connection. To enter codes, it is included in the standard iPhone port, to determine that the code came up, a photosensor is used, which is attached to the screen. And in order that the code counter does not decrease, the smartphone needs to disconnect the battery and supply power from the device. As a result, after each incorrect entry of the PIN-code, the device has time to break the power supply circuit before the counter of the remaining attempts decreases.

Naturally, after each break and power recovery, you have to wait until the phone boots again. As a result, it takes about 40 seconds to check one code. This means that checking all 4-digit codes can take up to 111 hours.



The obvious solution to this gap in the security of the device is to reduce the count of attempts to enter a code before checking the code for correctness. In the meantime, on devices up to 8.1 inclusive, the magic box works successfully. But in any case, if you put a long enough pin-code, such a brute force will no longer make sense. For example, it can take up to 125 years to select an 8-digit pin in this way.
