Yes, there actually is a $500 device for sale online that can crack iPhone 6 and 7 passcode. Apart from being almost cheap, it’s also very easy to use. Simply dial in settings in the desktop application, push them to the device, and then release the attack on a connected iPhone. Easy passcodes can be cracked in a short time. It all seems pretty impressive in action in a YouTube demonstration.
The device can recover passcodes of not one or two but three iPhone 7 at the same time. Believe it or not but an American YouTuber has published a video explaining the device.
The device attempts to brute force the code, beginning at 0000 and counting up (0001, 0002, …). The process continues until the correct password is recovered. Setting up demo iPhone with Passcodes like 0015 and 0016 guarantees that they’ll be discovered in a minimal amount of time. The phone’s response to the entered passcode works as a sign of passcode’s accuracy. The code is noted from the device and entered into the phone when the lock screen is displayed.
The method will only work if the password is short and belongs to the list of easy-to-guess passwords such as 123456, 5883 or 777777. This method works only on some models of iPhone 6 and 6s and it is completely compatible on iPhone 7 and 7 Plus.
