Apple’s latest and greatest iPhone, the iPhone X, received mixed reviews and sells slower than expected. While the high price of the new iPhone is a major factor influencing the slow sales, some of the negative points come from the device usability. The combination of design language, hardware and software interactions make using the new iPhone less than intuitive in many situations. In this article, we collected the list of utterly strange design decisions affecting the daily use of the iPhone X.

Breaking into iOS 11

February 20th, 2018 by Oleg Afonin

In the world of mobile forensics, physical acquisition is still the way to go. Providing significantly more information compared to logical extraction, physical acquisition can return sandboxed app data (even for apps that disabled backups), downloaded mail, Web browser cache, chat histories, comprehensive location history, system logs and much more.

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.

Forget battery issues. Yes, Apple issued an apology for slowing down the iPhone and promised to add better battery management in future versions of iOS, but that’s not the point in iOS 11.3. Neither are ARKit improvements or AirPlay 2 support. There is something much more important, and it is gong to affect everyone.

Lockdown files, otherwise known as pairing records, are well known to the forensic crowd for their usefulness for the purpose of logical extraction. A pairing file created on one computer (the user’s) can be used by the expert to pull information from the iOS device – that, without knowing the PIN code or pressing the user’s finger to unlock the device. Lockdown records do carry their fair share of limitations. For example, their use is severely restricted if the device has just rebooted or powered on and was not unlocked with a passcode afterwards.

Software updates remain a sore point for the 86 per cent of consumers who are using Android-based smartphones. Both Apple and Microsoft have significantly different update policies, mostly allowing the companies to deliver updates directly to their customers. There is much more to these updates than just the Android (or Windows) version. With numerous versions, subversions and carrier modified versions of the phone’s software, experts may struggle when attempting physical extraction. Let us have a look at the differences between the three mobile operating systems, their update policies and the challenges they present to the forensic examiner.

Thanks to its presence on Windows and Mac computers, iPhones and Android smartphones (on which it enjoys the default browser status), Google Chrome is the world’s most popular Web browser. In this article you’ll find a comprehensive guide on how to extract Google Chrome passwords from local computers and Google Account. We’ll also cover some common and some little known scenarios helping examiners put extracted passwords to good use – such as decrypting external NAS storage, unlocking BitLocker drives and attacking strong passwords. Let’s find out how to obtain Google Chrome passwords from multiple local and cloud sources such as the user’s Mac or Windows computer and their Google account.

iCloud authentication tokens in particular are difficult to grasp. What are they, what tools are they created with, where they are stored, and how and when they can be used are questions that we’re being asked a lot. Let’s try to put things together. Read Part 1 of the series.

What are iCloud authentication tokens? How they are better than good old passwords? Do they ever expire and when? Where to get them? Is there anything else I should know about tokens? This publication opens a new series on token-based authentication.
