The cloud becomes an ever more important (sometimes exclusive) source of the evidence whether you perform desktop or cloud forensics. Even if you are not in forensics, cloud access may help you access deleted or otherwise inaccessible data.

iOS 13 is on the way. While the new mobile OS is still in beta, so far we have not discovered many revolutionary changes in the security department. At the same time, there are quite a few things forensic specialists will need to know about the new iteration of Apple’s mobile operating system. In this article, we’ll be discussing the changes and their meaning for the mobile forensics.

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.

While the iPhone is Apple’s bread and butter product, is not the only device produced by the company. We’ve got the Mac (in desktop and laptop variations), the complete range of tablets (the iPad line, which is arguably the best tablet range on the market), the music device (HomePod), the wearable (Apple Watch), and the Apple TV. In today’s article, we are going to cover data extraction from Apple TV and Apple Watch. They do contain tons of valuable data, and are often the only source of evidence.

If you are familiar with breaking passwords, you already know that different tools and file formats require a very different amount of efforts to break. Breaking a password protecting a RAR archive can take ten times as long as breaking a password to a ZIP archive with the same content, while breaking a Word document saved in Office 2016 can take ten times as long as breaking an Office 2010 document. With solutions for over 300 file formats and encryption algorithms, we still find iTunes backups amazing, and their passwords to be very different from the rest of the crop in some interesting ways. In this article we tried to gather everything we know about iTunes backup passwords to help you break (or reset) their passwords in the most efficient way.

There has been a lot of noise regarding GrayKey news recently. GrayKey is an excellent appliance for iOS data extraction, and yes, it can help access more evidence. As always, the devil is in the detail.

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.

WhatsApp remains one of the most popular instant messengers. With more than 1.5 billion users and about half billion daily active users, WhatsApp sends over 100 billion messages per day. WhatsApp is secure thanks to end-to-end encryption to make intercepted messages impossible to decrypt. While this is great news to consumers and privacy advocates, it is also bad news for the law enforcement. Once an expert accepts to access the suspect’s WhatsApp communication history, they will struggle with the encryption and demand for a vendor-provided backdoor (WhatsApp: The Bad Guys’ Secret Weapon).

In Apple’s world, the keychain is one of the core and most secure components of macOS, iOS and its derivatives such as watchOS and tvOS. The keychain is intended to keep the user’s most valuable secrets securely protected. This includes protection for authentication tokens, encryption keys, credit card data and a lot more. End users are mostly familiar with one particular feature of the keychain: the ability to store all kinds of passwords. This includes passwords to Web sites (Safari and third-party Web browsers), mail accounts, social networks, instant messengers, bank accounts and just about everything else. Some records (such as Wi-Fi passwords) are “system-wide”, while other records can be only accessed by their respective apps. iOS 12 further develops password auto-fill, allowing users to utilize passwords they stored in Safari in many third-party apps.

The boom in personal electronic devices recording literally every persons’ step introduced a new type of forensic evidence: the digital evidence. In this day and age, significantly more forensic evidence is available in digital form compared to physical evidence of yesteryear. Are law enforcement and intelligence agencies ready to handle the abundance of digital evidence? And more importantly, do frontline officers have the skills and technical expertise required to handle and preserve this wealth of information?
