Acquiring data from locked, broken, or inaccessible devices poses significant challenges. However, there are ways to retrieve valuable information from such devices by obtaining the data from iCloud, including old data that has been deleted with no chance of recovery. In this article, we will explore the classic acquisition methods available for iOS devices and focus on the crucial role of Apple iCloud in forensic investigations.
Apple offers by far the most sophisticated solution for backing up, restoring, transferring and synchronizing data across devices belonging to the company’s ecosystem. Apple iCloud can store cloud backups and media files, synchronize essential information between Apple devices, and keep highly sensitive information such as Health and authentication credentials securely synchronized. In this article we’ll explain what kinds of data are stored in iCloud and what you need to access them.
The majority of mobile devices today are encrypted throughout, making extractions difficult or even impossible for major platforms. Traditional attack vectors are becoming a thing of the past with encryption being moved into dedicated security chips, and encryption keys generated on first unlock based on the user’s screen lock passwords. Cloud forensics is a great alternative, often returning as much or even more data compared to what is stored on the device itself.
This year is different from many before. The Corona pandemic, the lack of travel and canceled events had changed the business landscape for many forensic companies. Yet, even this year, we made a number of achievements we’d love to share.
The iPhone is one of the most popular smartphone devices. Thanks to its huge popularity, the iPhone gets a lot of attention from the forensic community. Multiple acquisition methods exist, allowing forensic users to obtain more or less information with more or less efforts. Some of these acquisition methods are based on undocumented exploits and public jailbreaks, while some other methods utilize published APIs to access information. In this article, we’ll compare the types and amounts of data one can extract from the same 256-GB iPhone 11 Pro Max using three different acquisition methods: advanced logical, full file system and iCloud extraction.
The past two years introduced a number of challenges forensic experts have never faced before. In 2018, Apple made it more difficult for the police to safely transport a seized iPhone to the lab by locking the USB port with USB restricted mode, making data preservation a challenge. The release of the A12 platform, also in 2018, made it difficult to unlock iOS devices protected with an unknown password, while this year’s release of iOS 13 rendered unlock boxes useless on iPhones based on the two most recent platforms.
If you are working in the area of digital forensics, you might have wondered about one particular thing in the marketing of many forensic solutions. While most manufacturers are claiming that their tools are easy to use and to learn, those very same manufacturers offer training courses with prices often exceeding the cost of the actual tools. Are these trainings necessary at all if the tools are as easy to use as the marketing claims?
Cloud analysis is arguably the future of mobile forensics. Whether or not the device is working or physically accessible, cloud extraction often allows accessing amounts of information far exceeding those available in the device itself.
