The second beta of iOS Forensic Toolkit 8.0 has arrived, offering repeatable, verifiable extraction for a limited range of iOS devices. The new release introduces a brand-new user interface, which differs significantly from the selection-driven console we’ve been using for the past several years. This article describes the new workflow for performing forensically sound extractions with iOS Forensic Toolkit 8.0 beta2.

Switching the iPhone into DFU mode is frequently required during the investigation, especially for older devices that are susceptible to checkm8 exploit. However, switching to DFU requires a sequence of key presses on the device with precise timings. If the device is damaged and one or more keys are not working correctly, entering DFU may be difficult or impossible. In this guide, we offer an alternative.

In just a few weeks, the new iPhone range will be released. Millions of users all over the world will upgrade, migrating their data from old devices. While Apple has an ingenious backup system in place, it has quite a few things behind the scenes that can make the migration not go as smooth as planned. How do you do the migration properly not to lose anything?

True physical acquisition is back – but only for a handful of old devices. We’re adding support for unlocking and forensically sound extraction of some of Apple’s legacy iPhones. For iPhone 4, 5, and 5c devices, we’re adding software-based passcode unlocking and device imaging functionality. Moreover, on some models you won’t even need to break the passcode in order to make a full disk image! In this walkthrough we’ll describe the steps required to image an iPhone 4, iPhone 5 or iPhone 5c device.

DFU Mode Cheat Sheet

The Device Firmware Upgrade mode, or simply DFU, just got a second breath. The ability to image the file system, decrypt the keychain and even do passcode unlocks on some older iPhone models has been made possible thanks to the checkm8 exploit and the checkra1n jailbreak, both of which require switching the phone into DFU. The procedure is undocumented, and the steps are different for the various devices.

If the iPhone is locked with a passcode, it is considered reasonably secure. The exception are some older devices, which are relatively vulnerable. But what if the passcode is known or is not set? Will it be easy to gain access to all of the data stored in the device? And why do we have the countless forensic tools –is analysis and reporting the sole reason for their existence? Not really. If you’ve been wondering what this acquisition thing is all about, this article is for you.

Stick It To The Man

The year was 2008, and I had been staying at a hotel in Bogota. This trip was just one of many to Columbia that year. Before my trip, I’d had my former girlfriend, Darci, stop by and help me swap out the hard drive in my MacBook Pro laptop. Remember, this is 2008, and at the time, replacing a drive in a MacBook Pro wasn’t nearly as easy as replacing hard drives these days. Darci swapped out my original hard drive with a brand-new drive, which I then formatted and installed macOS.  I had her swap the drive out for security reasons. I didn’t want to cross the border into a foreign country with all of my client data. Especially not after what happened to me in Atlanta! But we’ll get to that later.

When investigating iOS devices, you may have seen references to the SoC generation. Security researchers and developers of various iOS jailbreaks and exploits often list a few iPhone models followed by a note that mentions “compatible iPad models”. This is especially common when discussing iOS forensics, particularly referring to the checkra1n jailbreak. What do those references mean, and how are the iPhone and iPad models related? Can we count the iPod Touch and Apple TV, too? Let’s have a look.

We have discovered a way to unlock encrypted iPhones protected with an unknown screen lock passcode. Our method supports two legacy iPhone models, the iPhone 5 and 5c, and requires a Mac to run the attack. Our solution is decidedly software-only; it does not require soldering, disassembling, or buying extra hardware. All you need is iOS Forensic Toolkit (new version), a Mac computer, and a USB-A to Lightning cable. In this guide, we’ll demonstrate how to unlock and image the iPhone 5 and 5c devices.

A lot of people have asked me over the past couple of months – “What’s that cable on your desk, James?”. Today I’ll tell you all about it. Every accessory that connects to your iPhone via lightning is ‘flashed’ with an Accessory ID. The Accessory ID essentially identifies the device connected to the iPhone as a specific type. For example, a Lightning-To-Ethernet adapter will identify itself with it’s assigned Accessory ID so the iPhone knows how to treat the device and interact with it. It’s sort of like directing the iPhone to use a specific driver to interact with said device.
