Cloud acquisition is arguably the future of mobile forensics. Even today, cloud services by Apple and Google often contain more information than any single device – mostly due to the fact that cloud data is collected from multiple sources.

The iPhone X uses a new (for Apple) display technology. For the first time ever, Apple went with an OLED display instead of the IPS panels used in all other iPhones. While OLED displays have numerous benefits such as the true blacks and wide color gamut, the majority of OLED displays (particularly those made by Samsung) tend to flicker. The flickering is particularly visible at low brightness levels, causing eyestrain and headaches to sensitive users. Very few users have the slightest idea of what’s going on, attributing these health issues to oversaturated colors, the oh-so-harmful blue light and anything but OLED flickering.

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.

iOS is a locked down mobile operating system that does not allow its apps to directly access files in the file system. Unlike every other major mobile OS, iOS does not have a “shared” area in the file system to allow apps keep and share files with other apps. Yet, individual iOS apps are allowed to let the user access their files by using the file sharing mechanism.

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.

It’s been a long while since we made an update to one of our most technically advanced tools, Elcomsoft Forensic Disk Decryptor (EFDD). With this tool, one could extract data from an encrypted disk volume (FileVault 2, PGP, BitLocker or TrueCrypt) by utilizing the binary encryption key contained in the computer’s RAM. We could find and extract that key by analyzing the memory dump or hibernation files.

With over 1.3 billion monthly users, WhatsApp is the most popular instant messaging tool worldwide, and Android is the most popular mobile operating system by far. This makes WhatsApp acquisition from Android devices essential for the law enforcement. Elcomsoft Explorer for WhatsApp 2.30 can now download and decrypt Android user’s encrypted WhatsApp communication histories stored in Google Drive. If you have access to the user’s trusted phone number or their physical SIM card (to receive a verification code from WhatsApp), you can now use Elcomsoft Explorer for WhatsApp to download, decrypt and display WhatsApp communication histories backed up into the user’s Google Account. Surprisingly, a cloud backup may, in certain cases, contain even more information than stored on the device itself. This particularly applies to attachments (photos and videos) sent and received by WhatsApp users and then deleted from the device.

Media files (Camera Roll, pictures and videos, books etc.) are an important part of the content of mobile devices. The ability to quickly extract media files can be essential for an investigation, especially with geotags (location data) saved in EXIF metadata. Pulling pictures and videos from an Android smartphone can be easier than obtaining the rest of the data. At the same time, media extraction from iOS devices, while not impossible, is not the easiest nor the most obvious process. Let’s have a look at tools and techniques you can use to extract media files from unlocked and locked iOS devices.

Who am I to tell you to use two-factor authentication on all accounts that support it? This recommendation coming from someone whose business is supplying law enforcement with tools helping them do their job might be taken with a grain of salt by an average consumer. Yet we still strongly believe that, however good a password you have to encrypt your local documents or NAS drives, any remotely popular online service absolutely requires an additional authentication factor.

Two-factor authentication is essential to secure one’s access to online accounts. We studied multiple implementations of two-factor authentication including those offered by Apple, Google and Microsoft. While Google’s implementation offers the largest number of options, we feel that Apple has the most balanced implementation. The closed ecosystem and the resulting deep integration with the core OS makes it easy for Apple to control exactly how it works and on which devices.
