Apple has a wonderfully integrated ecosystem. Apple computers, tablets and phones conveniently synchronize information such as passwords, Web browsing history, contacts and call logs across all of the user’s devices. This synchronization mechanism uses iCloud to sync and store information. The syncing mechanism works independently from iOS system backups that are also stored in iCloud (or iCloud Drive). As opposed to daily iCloud backups, synchronized data is updated and propagated across devices in almost real time. Extracting this information can be invaluable for investigations as it provides access to the most up to date information about the user, their activities and whereabouts.

Who needs access to iCloud Keychain, and why? The newly released Elcomsoft Phone Breaker 7.0 adds a single major feature that allows experts extracting, decrypting and viewing information stored in Apple’s protected storage. There are so many ifs and buts such as needing the user’s Apple ID and password, accessing their i-device or knowing a secret security code that one may legitimately wonder: what is it all about? Let’s find out about iCloud Keychain, why it’s so difficult to crack, and why it can be important for the expert.

Every once in a while, hi-tech companies release reports on government requests that they received and served (or not). The different companies receive a different number of requests. They don’t treat them the same way, and they don’t report them the same way, which makes the comparison difficult. In this article, we’ll try to analyze and compare government request reports published by Apple, Google and Microsoft.

Two-factor authentication a roadblock when investigating an Apple device. Obtaining a data backup from the user’s iCloud account is a common and relatively easy way to acquire evidence from devices that are otherwise securely protected. It might be possible to bypass two-factor authentication if one is able to extract a so-called authentication token from the suspect’s computer.

In this article we’ll discuss the differences between implementations of two-factor authentication in popular mobile platforms. We’ll research how two-factor authentication is implemented in Android, iOS and Windows 10 Mobile, and discuss usability and security implications of each implementation.

The previous article was about the theory. In this part we’ll go directly to practice. If you possess a turned on and locked iOS device and have no means of unlocking it with either Touch ID or passcode, you may still be able to obtain a backup via the process called logical acquisition. While logical acquisition may return somewhat less information compared to the more advanced physical acquisition, it must be noted that physical acquisition may not be available at all on a given device.

In recent versions of iOS, successful acquisition of a locked device is no longer a given. Multiple protection layers and Apple’s new policy on handling government requests make forensic experts look elsewhere when investigating Apple smartphones.

We discovered a major security flaw in the iOS 10 backup protection mechanism. This security flaw allowed us developing a new attack that is able to bypass certain security checks when enumerating passwords protecting local (iTunes) backups made by iOS 10 devices.

For many months, a working jailbreak was not available for current versions of iOS. In the end of July, Pangu released public jailbreak for iOS 9.2-9.3.3. A few days ago, Apple patched the exploit and started seeding iOS 9.3.4. This was the shortest-living jailbreak in history.
