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.
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.
In our previous blog post, we wrote everything we know about authentication tokens and Anisette data, which might allow you to bypass the “login, password and two-factor authentication” sequence. Let us have a look at how you can actually extract those tokens from a trusted computer and use them on a different computer to access a user’s iCloud account. Read Part 1 and Part 2 of the series.
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.
We loved what Apple used to do about security. During the past years, the company managed to build a complete, multi-layer system to secure its hardware and software ecosystem and protect its customers against common threats. Granted, the system was not without its flaws (most notably, the obligatory use of a trusted phone number – think SS7 vulnerability – for the purpose of two-factor authentication), but overall it was still the most secure mobile ecosystem on the market.
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.
Google has started its journey on convincing people to move away from SMS-based verification, and start receiving push messages via the Google Prompt instead of using six-digit codes. Why does Google want us away from SMS, and why using Google Prompt instead? Let’s try to find out.
Since early days of iOS, iTunes-style system backups could be protected with a password. The password was always the property of the device; if the backup was protected with a password, it would come out encrypted. It didn’t matter whether one made a backup with iTunes, iOS Forensic Toolkit or other forensic software during the course of logical acquisition; if a backup password was enabled, all you’d get would be a stream of encrypted data.
Even today, seizing and storing portable electronic devices is still troublesome. The possibility of remote wipe routinely makes police officers shut down smartphones being seized in an attempt to preserve evidence. While this strategy used to work just a few short years ago, this strategy is counter-productive today with full-disk encryption. In all versions of iOS since iOS 8, this encryption is based on the user’s passcode. Once the iPhone is powered off, the encryption key is lost, and the only way to decrypt the phone’s content is unlocking the device with the user’s original passcode. Or is it?
