The controversy of the day in the world Apple Lossless Audio CODEC (ALAC), It's about the possibility or impossibility of the American company to access data from any iPhone sold worldwide, some saying this is possible, while others strongly support Apple's position.
The problem is this: if an iPhone has a security code, then a brute force attack would cause it to be completely locked because one iOS setting can completely wipe an iPhone after 10 wrong codes, while another set a period of time that must pass between each code entry.
Apple says that limitations of this kind, plus others, make it impossible to access data from an iPhone locked with a security code, but the Trail of Bits company claims that Apple has the necessary technical ability to access data from any type of iPhone.
More precisely, putting an iPhone in DFU Mode would allow the rewriting of its firmware and the removal of protection measures for brute force attacks on the iDevice, the FBI then being able to crack the security code if it only has 4 digits.
[Apple] will bypass or disable the auto-erase function whether or not it has been enabled;
[Apple] will enable the FBI to submit passcodes to the SUBJECT DEVICE for testing electronically via the physical device port, Bluetooth, Wi-Fi, or other protocol available on the SUBJECT DEVICE; and [Apple] will ensure that when the FBI submits passcodes to the SUBJECT DEVICE, software running on the device will not purposefully introduce any additional delay between passcode attempts beyond what is incurred by Apple hardware.
Although some claim that this method is only possible on terminals that have Touch ID, a former Apple employee, now an expert in computer security, claims that data from iDevices can also be accessed on those terminals, also through similar tricks.
Basically, Apple is lying when it says that it cannot access the data from an iDevice locked with a security code, it having the necessary technique to do this, even if an ordinary person or an ordinary criminal could not do it.
