On the other hand, leveraging hardware for security makes every attack visible and presents the toughest barriers for attackers to overcome. Hacking hardware can bypass all software-based controls. There is no doubt hardware is the final frontier in cybersecurity. With a more powerful system, a crack could occur much faster.

Even with such a rudimentary system, a four-digit code was cracked in about 40 hours. Thus automating the process, a brute-force attack succeeded. It reset the counter after every pin attempt. The researcher created a cloned NAND memory chip under his control, to replace the one embedded in the iPhone.

Attempts to try even a small number of them will result in the phone quickly being locked and ultimately the data rendered unrecoverable. A four-digit pin has 10,000 possible combinations, from 0000 to 9999. This check is controlled in the firmware and hardware of the device to prevent a brute-force attack, which is designed to try all combinations. After 10 attempts the device permanently deletes the encryption keys, making all the data on the phone irretrievable.

After a certain number of attempts, the phone will wait for a long period before allowing another attempt. The iPhone 5C security control in question is one thatВ limits the number of attempts to enter an unlocking PIN. Recently a security researcher wrote a paper and then built a hacking rig to do the same, for about $100. Ultimately, the FBI dropped the legal case against Apple and reportedly paid $1 million to an unknown security company to unlock the phone.

Apple refused on ethical grounds and a media frenzy ensued. This is the same lock thatВ stymied the FBI as part of the highly publicized privacy case in whichВ they demanded Apple create a workaround to access the phone of the San Bernardino, Calif., shooter. A security researcher from the University of Cambridge has found a way to hack the iPhone NAND memory hardware to sufficiently bypass an important security feature, allowing a brute-force attack against the passcode lock of an iPhone 5C.
