Learning Python for Forensics

By: Chapin Bryce

Overview of this book

This book will illustrate how and why you should learn Python to strengthen your analysis skills and efficiency as you creatively solve real-world problems through instruction-based tutorials. The tutorials use an interactive design, giving you experience of the development process so you gain a better understanding of what it means to be a forensic developer. Each chapter walks you through a forensic artifact and one or more methods to analyze the evidence. It also provides reasons why one method may be advantageous over another. We cover common digital forensics and incident response scenarios, with scripts that can be used to tackle case work in the field. Using built-in and community-sourced libraries, you will improve your problem solving skills with the addition of the Python scripting language. In addition, we provide resources for further exploration of each script so you can understand what further purposes Python can serve. With this knowledge, you can rapidly develop and deploy solutions to identify critical information and fine-tune your skill set as an examiner.

Our final iteration – setupapi_parser.py


In our final iteration, we will continue to improve the script through adding deduplication of processed entries and improving upon the output. Although the second iteration introduced the logic for filtering out non-USB devices, it does not deduplicate the responsive hits. We will deduplicate on the device name to ensure that there is only a single entry per device. In addition, we will integrate our usb_lookup.py script from Chapter 2, Python Fundamentals, to improve the utility of our script by displaying USB Vendor IDs (VIDs) and Product IDs (PIDs) for known devices.

We had to modify code in the usb_lookup.py script to properly integrate it with the setupapi script. The differences between the two versions are subtle and are focused on reducing the number of function calls and improving the quality of the returned data. Throughout this iteration, we will discuss how we have implemented our custom USB VID/PID lookup library to resolve USB device...
