Reverse Engineering with GDB: Analyzing Unoptimized Disassembly

To truly understand how your software behaves under the hood, you must look past high-level code and examine what the CPU actually executes. Analyzing unoptimized disassembly is the crucial first step in reverse engineering, malware analysis, and low-level debugging because it preserves a direct, one-to-one mapping to your original source code. This course guides you through the fundamental mechanics of reading compiler output and reconstructing program logic from scratch. You will transition from reading standard C and C++ source code to confidently navigating raw assembly instructions. By learning how compilers translate variables, control flow, and complex pointer operations into machine instructions, you will gain a deep understanding of software execution and memory layout. What you'll learn: - Understand the core x86-64 assembly instructions and register functions - Navigate the GDB command-line interface to inspect memory and registers - Reconstruct complex C and C++ pointer operations from disassembly output - Map assembly instruction sequences back to original loop structures and conditional statements - Trace stack frames, local variables, and function call sequences in memory - Apply modern security debugging concepts, including identifying basic buffer overflow patterns This course begins with foundational concepts, establishing a clear understanding of CPU registers, memory segmentation, and assembly syntax. You will then progress through structured, text-based walkthroughs that analyze increasingly complex code structures, pointer arithmetic, and function calls directly inside GDB. This program is designed for beginner reverse engineers, security enthusiasts, and systems programmers who have a basic familiarity with C or C++ but have no prior experience with assembly or GDB.
