Developing custom modules

Let's dig deeper into the process of writing a module. Metasploit has various modules such as payloads, encoders, exploits, NOP generators, and auxiliaries. In this section, we will cover the essentials of developing a module; then, we will look at how we can create our custom modules.

We will discuss the development of auxiliary and post-exploitation modules. Additionally, we will cover core exploit modules in the next chapter. But, for this chapter, let's examine the essentials of module building in detail.

Building a module in a nutshell

Before diving deep into building modules, let's understand how the components are arranged in the Metasploit framework, and what they do.
