The iPhone is one of the most popular smartphone devices. Thanks to its huge popularity, the iPhone gets a lot of attention from the forensic community. Multiple acquisition methods exist, allowing forensic users to obtain more or less information with more or less efforts. Some of these acquisition methods are based on undocumented exploits and public jailbreaks, while some other methods utilize published APIs to access information. In this article, we’ll compare the types and amounts of data one can extract from the same 256-GB iPhone 11 Pro Max using three different acquisition methods: advanced logical, full file system and iCloud extraction.

Geolocation data can provide a wealth of evidence to various government agencies. Law enforcement agencies use location data to help place suspects near a crime scene in a given time frame. However, the use of location is not limited to criminal or civil investigations. Emergency response services use geolocation to locate persons, taxi and delivery services use location to improve service. There are many more examples where location evidence is vital. Recently, governments have started using (or are considering using) geolocation data to help identify and isolate infected citizens. Where does the location evidence come from and how one can extract it?

Every other day, Apple makes the work of forensic specialists harder. Speaking of iCloud, we partially covered this topic in Apple vs. Law Enforcement: Cloud Forensics and Apple vs Law Enforcement: Cloudy Times, but there is more to it today. The recent iOS (13.4) and macOS (10.15.4) releases brought some nasty surprises. Let’s talk about them.

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.

What is DFU, and how is it different from the recovery mode? How do you switch the device to recovery, DFU or SOS mode, what can you do while in these modes and what do they mean in the context of digital forensics? Can you use DFU to jailbreak the device and perform the extraction if you don’t know the passcode? Read along to find out.

The Screen Time passcode (known as the Restrictions passcode in previous versions of iOS) is a separate 4-digit passcode designed to secure changes to the device settings and the user’s Apple ID account and to enforce the Content & Privacy Restrictions. You can add the Screen Time passcode when activating Screen Time on a child’s device or if you want to add an extra layer of security to your own device.

We all know how much important data is stored in modern smartphones, making them an excellent source of evidence. However, data preservation and acquisition are not as easy as they sound. There is no silver bullet or “fire and forget” solutions to solve cases or extract evidence on your behalf. In this article, which is loosely based on our three-day training program, we will describe the proper steps in the proper order to retain and extract as much data from the iPhone as theoretically possible.

The new generation of jailbreaks has arrived for iPhones and iPads running iOS 12. Rootless jailbreaks offer experts the same low-level access to the file system as classic jailbreaks – but without their drawbacks. We’ve been closely watching the development of rootless jailbreaks, and developed full physical acquisition support (including keychain decryption) for Apple devices running iOS 12.0 through 12.1.2. Learn how to install a rootless jailbreak and how to perform physical extraction with Elcomsoft iOS Forensic Toolkit.

The two recent jailbreaks, unc0ver and Electra, have finally enabled file system extraction for Apple devices running iOS 11.4 and 11.4.1. At this time, all versions of iOS 11 can be jailbroken regardless of hardware. Let’s talk about forensic consequences of today’s release: keychain and file system extraction.

The release of iOS 11.4.1 back in July 2018 introduced USB Restricted Mode, a feature designed to defer passcode cracking tools such as those developed by Cellerbrite and Grayshift. As a reminder, iOS 11.4.1 automatically switches off data connectivity of the Lightning port after one hour since the device was last unlocked, or one hour since the device has been disconnected from a USB accessory or computer. In addition, users could manually disable the USB port by following the S.O.S. mode routine.
