Learning Python for Forensics

Learning Python for Forensics

By: Miller, 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.

Introduction to ID3 metadata


The ID3 metadata container is often associated with MP3 files. There are two versions of the embedded structure: ID3v1 and ID3v2. The ID3v1 version is the final 128 bytes of the file and has a different structure from the updated format. The newer version, which we will focus on, is located at the beginning of the file and is variable in length.

An ID3 tag has a simpler structure compared with EXIF tags. The first 16 bytes are evenly split between the tag ID and the length of the metadata. Following that is the metadata itself. The following screenshot contains the first 144 bytes of an MP3 file:

The file signature of MP3 files is the ASCII "ID3". Shortly after the signature, we can see different tags, such as TP1, TP2, and TCM. These are metadata tags for the artist, band, and composer, respectively. The next 8 bytes following TP1 is the length represented by the hex 0x0B or 11. Following a 2-byte buffer, is the data for the artist formerly known as "The Artist...
