Apple iMessage is an important communication channel and an essential part of forensic acquisition efforts. iMessage chats are reasonably secure. Your ability to extract iMessages as well as the available sources of extraction will depend on several factors. Let’s discuss the factors that may affect your ability to extract, and what you can do to overcome them.

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.

iOS 14 is officially out. It’s a big release from the privacy protection standpoint, but little had changed for the forensic expert. In this article, we’ll review what has changed in iOS 14 in the ways relevant for the forensic crowd.

The checkra1n jailbreak is fantastic. Not only does it work with the latest versions of iOS the other jailbreaks aren’t even available for, but it also allows performing partial data extraction from disabled and locked iPhones even if the passcode is not known. Still, you can encounter some problems if the USB restricted mode has been activated on the device. The latest build of chechra1n is to the rescue.

Having trouble installing the checkra1n jailbreak? If you do it right, you achieve a nearly 100% success rate. We have collected the most important information on how to install and troubleshoot the checkra1n jailbreak. By following these advises, you will be able to jailbreak like a pro, whether you just want to research your own device or perform the file system and keychain acquisition.

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.

Extracting the fullest amount of information from the iPhone, which includes a file system image and decrypted keychain records, often requires installing a jailbreak. Even though forensically sound acquisition methods that work without jailbreaking do exist, they may not be available depending on the tools you use. A particular combination of iOS hardware and software may also render those tools ineffective, requiring a fallback to jailbreak. Today, the two most popular and most reliable jailbreaks are checkra1n and unc0ver. How do they fare against each other, and when would you want to use each?

The USB restricted mode was introduced in iOS 11.4.1, improved in iOS 12 and further strengthened in iOS 13. The USB restrictions are a real headache for iPhone investigators. We’ve discovered a simple yet effective trick to fool it in some cases, but currently it securely protects the iPhones from passcode cracking and BFU (Before First Unlock) extractions. However, there is a trick allowing you to obtain some information from devices with disabled USB interface. Learn how to use this trick with the recently updated iOS Forensic Toolkit.

We recently introduced a new acquisition method for iPhone and iPad devices. The fast, simple and safe extraction agent requires no jailbreak, and delivers the full file system image and the keychain. The latest release of Elcomsoft iOS Forensic Toolkit expanded this method to iOS 13 and filled the gaps in some versions of iOS 12 that were missing support (such as iOS 12.3 and 12.4.1). Finally, we now officially support the latest generation of iPhone devices including the iPhone 11, iPhone 11 and iPhone 11 Pro. The new compatibility matrix becomes significantly more diverse with this release, so bear with us to learn which iOS devices can be extracted without a jailbreak.

Are you excited about the new checkm8 exploit? If you haven’t heard of this major development in the world of iOS jailbreaks, I would recommend to read the Technical analysis of the checkm8 exploit aricle, as well as Developer of Checkm8 explains why iDevice jailbreak exploit is a game changer. The good news is that a jailbreak based on this exploit is already available, look at the checkra1n web site.
