The Basics of Analyzing and Creating Structures in IDA Pro - Part 1

In this video, part of a 3 video series, we'll look at what a basic structure is, discuss how it uses memory and use a sample program to create a compiled binary for reverse engineering. We'll then use IDA Pro to analyze the code and identify signs of structure usage. This video will cover the use of dynamically allocated memory used for this structure. We'll also cover structure analysis using IDA's decompiler. Finally, we'll create a custom structure and discuss how to apply this structure to the disassembled and decompiled code.
