![]() Use USB-A to Lightning cable only (no USB-C to Lightning).Check out checkra1n Installation Tips & Tricks, in particular:.Note that there is an extra mandatory step on macOS Catalina. Install the toolkit by following the instructions in How to Install and Run iOS Forensic Toolkit on a Mac.Download Elcomsoft iOS Forensic Toolkit.You can use the optional USB-C to USB-A adapter if needed.įirst, install iOS Forensic Toolkit and make yourself familiar with the checkra1n jailbreak by following these preliminary steps: Please use USB-A to Lightning due to known incompatibilities in Apple’s and most third-party USB-C to Lightning cables. ![]() ![]() A desktop or laptop computer with macOS 10.12 (Sierra) through 10.15 (Catalina).In order to launch the attack, you will need all of the following. We will probably add support for alphanumeric passwords in the next version. If an alphanumeric passcode is detected, you’ll see the “unsupported” message, and the attack will stop. For the time being, iOS Forensic Toolkit does not support alphanumeric passwords. Alphanumeric passcodesĪt the given speed, the recovery of an alphanumeric passcode becomes extremely iffy unless you have targeted dictionary of the user’s other passwords. Only after these options are exhausted do we start the full brute-force attack that lasts around 21 hours. Following this list are the 6-digit PINs based on the user’s date of birth there are around 74K possible combinations that take about 1.5 hours to try. There are 2910 commonly used 6-digit PINs, and it only takes about 4 minutes to test them all. For this reason, we’ll try the most popular passcodes first. The enumeration of all 6-digit PINs, however, will take up to 21 hours. Disabling these mechanisms removes the risk of losing the data and turns off the escalating time delay, enabling the attack to work at a full speed of exactly 13.6 passcodes per second, which is very close to Apple’s target of 80ms between passcode attempts.Ĭonsidering the speed of 13.6 passcodes per second, it only takes 12 minutes to try all possible combinations of 4-digit PINs. As a result, both the escalating time delays after the entry of an invalid passcode at the Lock screen and the optional setting to wipe the device after 10 unsuccessful attempts are enforced in software by iOS. While newer devices (the iPhone 5s and subsequent models) rely on Secure Enclave to slow down attacks to a crawl, 32-bit devices such as the iPhone 5 and 5c are not equipped with a hardware security coprocessor. Passcode attacks: know your optionsĪpple implements strong protection to defend its devices against brute force attacks. In this guide, we’ll demonstrate how to unlock and image the iPhone 5 and 5c devices. All you need is iOS Forensic Toolkit (new version), a Mac computer, and a USB-A to Lightning cable. Our solution is decidedly software-only it does not require soldering, disassembling, or buying extra hardware. Our method supports two legacy iPhone models, the iPhone 5 and 5c, and requires a Mac to run the attack. We have discovered a way to unlock encrypted iPhones protected with an unknown screen lock passcode.
