TARGET: BINARY ANALYSIS FUNDAMENTALS

Reverse Engineering is not about reading code; it is about reconstructing intent. When you open a binary in Ghidra or IDA Pro, you are looking at the “corpse” of a program. Your job is to perform the autopsy and find out how it lived.

0x01: The Black Box Theory

Imagine a locked door with no key. You can’t see inside, but you can see what goes under the door (Input) and what comes out of the mail slot (Output).

• Static Analysis: Looking at the door’s hinges, the wood type, and the lock manufacture without touching it.
• Dynamic Analysis: Kicking the door, trying 1,000 keys, and watching how the door vibrates.

0x02: The Hardware Abstraction Layer

Before we touch a debugger, you must understand the hierarchy of communication:

1. The Human: Writes C++.
2. The Compiler: Translates C++ to Assembly.
3. The CPU: Executes Opcodes (Hexadecimal).
