Headline news report that law enforcement agencies across the country have purchased GrayKey, a relatively cheap tool for bypassing the encryption on iPhones, while the FBI pushes again for encryption backdoors. It looks that a great opportunities for technology firm. It can receive rewards. It is indeed a win win situation. Tech firm can earn money. The court is able to collect the evidences to do the right judgement. Meanwhile, I was wonder whether this is the only way to open the backdoor? As we know, jailbreak the iPhone not a secret. The default password looks easily to collect. So far, the cheap tool to do the magic are available. Perhaps you cannot unlock the phone directly. However you are able to get in (see attached diagram for reference). I beleive that there are more possible way and idea will be coming soon.
