Asking the Right Questions: Forensic Analysis of Data, or How to Make BlackBerry Data Hearsay

Tutored by television crime dramas, many people have come to assume that electronic information is always what it appears to be on its face. This is, in fact, the forensic version of a longstanding tendency that people have to believe anything that comes from the computer, no matter how absurd.

We will consider a brief history of the forensic analysis of data, showing what is and is not possible with various types of electronic information. Drawing from our own practice in high-stakes criminal and civil adjudication, we will illustrate the difference between knowledge and understanding—and how failing to recognize the difference can prove disastrous.

In the second half of this presentation, we focus on the forensic analysis of mobile devices, with particular emphasis on BlackBerry devices. We will present for the first time original research undertaken at Interhack and perform a demonstration showing how standard forensic tools, including Secure View and Paraben, will fail to detect implanted and backdated data in BlackBerry devices.
