Socket programming in Python
Before learning about malware development, it is necessary that we learn about network programming in Python and how we can create network applications. The first step in learning network programming is to learn about what we call sockets. Sockets provide a fundamental mechanism for creating network-based applications and our malware is going to be essentially a network application. Let's start by understanding sockets first.
Sockets
Before we jump into socket programming, let's first understand what a network socket is and how it can be used to develop network-based applications. As we learned in previous chapters, the topmost layer in a network stack is an application layer. These are the applications that the user interacts with in everyday life. Now, the question is, how do these applications, which are developed in different programming languages, communicate over the network? The answer lies in the use of sockets. A socket is defined...
