Let’s take a look at some loops. Loops are pretty simple, but they are easy to miss if you are just skimming over the disassembly. When reversing a binary you won’t see keywords like “while” or “fo...

A “Hello World” program isn’t going to be much different than the one covered in 5.2 FunctionCall. There are many ways to make program print “Hello World!” in C++, I will be showing the two main wa...

Before We Begin The name of the program in the following examples is “Testing.exe”. This is why you will see “testing.*” prepended to some things. Parameters do not have to be set in any orde...

I’m excited that we are now to this point in the course. If I’m being honest, all that other stuff is pretty boring. This is the real fun stuff! Before we start reverse engineering you need to be ...

This chapter will introduce you to some vital reversing concepts by taking a look at some very simple programs. Chapter 5 - BasicReversing 5.0 BasicReversing 5.1 Before We Begin 5.2 Functio...

4.3 Tool Guides It’s important to know how to use the software you are using. This lesson will cover some tool basics. It’s best to use this lesson as a reference when the tools first get introduc...
