Investigative Reversing 0 & 1 - When Reverse Engineering Meets Forensics

The article "Investigative Reversing 0 & 1 — When Reverse Engineering Meets Forensics" discusses a unique approach to solving Capture The Flag (CTF) challenges that blend traditional reverse engineering with digital forensics. Here's a summary of the key points and insights from the article:

Key Points

1. Combination of Techniques:

   • Challenges require understanding how data is transformed by analyzing both binary code and external files.
   • The goal is to reconstruct hidden information using clues from multiple sources.

2. Challenge Structure:

   • Two challenges are described: one involving a single image file and another with three image files.
   • Both challenges involve extracting and reversing transformations applied to the flag data.

3. Binary Analysis:

   • Analyzing the binary code reveals how data is manipulated, but not necessarily where the final answer lies.
   • Understanding the transformation logic is crucial for reconstructing the original data.

4. File Inspection:

   • Files need to be treated as raw byte sequences rather than just text or images.
   • Non-printable bytes and raw binary data can contain critical information.

5. Reconstruction Process:

   • The final flag often needs
