The 5 Levels of Reverse Engineering

A comprehensive guide to reverse engineering that progresses through five skill levels: strings analysis for quick insights, static analysis using disassemblers like IDA and Ghidra to understand program logic, dynamic analysis with debuggers like GDB to observe runtime behavior, symbolic execution with tools like Angr to automatically solve program constraints, and real-world vulnerability research in embedded devices. Each level builds on the previous, demonstrating practical techniques for analyzing malware, solving crackme challenges, and discovering security flaws in firmware.
