iOS Forensic Toolkit 7.10 brings low-level file system extraction support for a bunch of iOS versions. This includes the entire range of iPhone models based on the A11, A12, and A13 Bionic platforms running iOS 14.4 through 14.8.

Half a year ago, we started a closed beta-testing of a revolutionary new build of iOS Forensic Toolkit. Using the checkm8 exploit, the first beta delivered forensically sound file system extraction for a large number of Apple devices. Today, we are rolling out the new, significantly improved second beta of the tool that delivers repeatable, forensically sound extractions based on the checkm8 exploit.

The previous publication talks about the basics of using the bootloader-level exploit for extracting iOS devices. In this article, we are posting a comprehensive step-by-step guide of using the new checkm8 capability of iOS Forensic Toolkit for performing forensically sound extractions of a range of Apple devices.

After adding jailbreak-free extraction for iOS 13.5.1 through 13.7, we now support every Apple device running any version of iOS from 9.0 through 13.7 with no gaps or exclusions. For the first time, full file system extraction and keychain decryption are possible on all devices running these iOS versions.

If you are familiar with iOS acquisition methods, you know that the best results can be obtained with a full file system acquisition. However, extracting the file system may require jailbreaking, which may be risky and not always permitted. Are there any reasons to use jailbreaks for extracting evidence from Apple devices?

It’s been a week since Apple has released iOS 14.2 as well as iOS 12.4.9 for older devices. Just a few days later, the developers updated the checkra1n jailbreak with support for new devices and iOS versions. What does that mean for iOS forensics? Let’s have a look; we have done some testing, and our discoveries are positively consistent with our expectations. Just one exception: to our surprise, Apple did not patch the long lasting vulnerability in iOS 12.4.9 that leaves the door open to full file system extraction and keychain acquisition without jailbreaking.

Last year, we have developed an innovative way to extract iPhone data without a jailbreak. The method’s numerous advantages were outweighed with a major drawback: an Apple ID enrolled in the paid Apple’s Developer program was required to sign the extraction binary. This is no longer an issue on Mac computers with the improved sideloading technique.

How can you obtain the highest amount of data from an iPhone, iPad, Apple TV or Apple Watch? This is not as simple as it may seem. Multiple overlapping extraction methods exist, and some of them are limited to specific versions of the OS. Let’s go through them and summarize their availability and benefits.

The unc0ver v5 jailbreak has been available for a while now. It supports the newest versions of iOS up to and including iOS 13.5, and this is fantastic news for DFIR community, as it allows extracting the full file system and the keychain when acquiring the newest latest iPhone models such as the iPhone 11 and 11 Pro, and SE 2020. In this article, I’ll talk about the unc0ver jailbreak, the installation and usage for the purpose of file system extraction, and discuss the differences between jailbreak-based and jailbreak-free extraction.

Elcomsoft iOS Forensic Toolkit 6.0 is out, adding direct, forensically sound extraction for Apple devices running some of the latest versions of iOS including iOS 13.3.1, 13.4 and 13.4.1. Supported devices include the entire iPhone 6s, 7, 8, X, Xr/Xs, 11, and 11 Pro (including Plus and Max versions) range, the iPhone SE, and corresponding iPad models. Let’s review the changes and talk about the new acquisition method in general.
