We have covered the basics of Metasploit, so now we can move further into the underlying coding part of the Metasploit framework. We will start with the basics of Ruby programming to understand various syntaxes and its semantics. This chapter will make it easy for you to write Metasploit modules. In this chapter, we will see how we can design and fabricate various Metasploit modules with the functionality of our choice. We will also look at how we can create custom post-exploitation modules, which will help us gain better control of the exploited machine.
Consider a scenario where the number of systems under the scope of the penetration test is massive, and we crave a post-exploitation feature such as downloading a particular file from all the exploited systems. Manually, downloading a specific file from each system is not only time-consuming, but inefficient...
