‘Researchers crack improved protection against unlock tools from iOS beta’




usb restricted mode that Apple introduces in a beta version of iOS 12 to combat USB unlocking tools would already be cracked by one of the creators of such tools. Although they claim this, they have not yet given a demonstration of this.

Earlier this month it came out that Apple is working on a restricted restricted fashion for iOS 12. It simply means that USB devices can not interact with an iPhone unless it has been unlocked in the past hour. The phone can then only be loaded via USB, data traffic is not allowed. In earlier versions of iOS this measure is also, but then the time period was a week. The shorter time period would make unlocking tools unusable.

In an e-mail that Motherboard has seen , a forensic expert states that GrayShift, the developer of the GrayKey unlock tool, “works hard to make its tools future-proof and has already defeated the beta build-up measures.” Another person in the e-mail conversation states that Grayshift had already dealt with usb restricted fashion during a webinar a few weeks ago.

Such unlock tools are offered by not only GrayShift, but also the Israeli Cellebrite. Other research by Motherboard would show that such tools are in practice deductible from American police forces. According to Forbes, GrayKey would cost $ 15,000 for 300 uses , and $ 30,000 for unlimited use. The tool would work on iOS 10 and 11, with support for iOS 9 in the future. The device uses techniques to brute force the decryption code of an iPhone as quickly as possible and thereby circumvent the measures against too many wrong codes .
