Analyzing Windows Phone 8.1 JTAG and UFED Dumps

In recent months, we’ve started receiving calls from our customers asking us about extracting files and looking for evidence in binary dumps extracted out of Windows Phone 8 devices. We’ve got dozens of requests from European police departments, especially those from Germany, Italy, and the UK about extracting and analyzing JTAG and UFED-produced dumps of Windows phones. While in the past we were reluctant to work in this direction considering how small of a market share these devices had, the recently published numbers of every 10th device sold in Europe being a Windows Phone made us change our mind.

Meet the newest release of Belkasoft Evidence Center! In this release, we’ve added the ability to process, parse, and extract information stored in binary dumps of Windows Phone devices captured with JTAG or Cellebrite UFED hardware. We can fully reconstruct the original file system of the device, allowing experts to browse through the file system and view and extract individual files and folders.

Our signature discovery and analytics are also there for Windows Phone data. The updated Belkasoft Evidence Center will automatically search for, extract and analyze the many types of evidence essential for your investigation. Contacts and address books, call logs, Skype chats and communication histories in third-party messengers, browsing history and cached social network conversations are carefully extracted and added to the list of available evidence.

Forensic Analysis of SQLite Databases: Free Lists, Write Ahead Log, Unallocated Space and Carving

SQLite is a widely popular database format that is used extensively pretty much everywhere. Both iOS and Android employ SQLite as a storage format of choice, with built-in and third-party applications relying on SQLite to keep their data. A wide range of desktop and mobile Web browsers (Chrome, Firefox) and instant messaging applications use SQLite, which includes newer versions of Skype (the older versions don’t work anyway without a forced upgrade), WhatsApp, iMessages, and many other messengers.

Forensic analysis of SQLite databases is often concluded by simply opening a database file in one or another database viewer. One common drawback of using a free or commercially available database viewer for examining SQLite databases is the inherent inability of such viewers to access and display recently deleted (erased) as well as recently added (but not yet committed) records. In this article, we’ll examine the forensic implications of three features of the SQLite database engine: Free Lists, Write Ahead Log and Unallocated Space.
