Packaging the malware
The program we developed in Chapter 7, Advanced Malware, was a Python file. It also contained some dependencies. It is very hard to run a Python file on a victim's machine without having physical access to it. This makes our program not very useful unless we have a way to package everything together into a single executable that we can ship to the victim and when the victim opens it, it creates a reverse shell to the hacker's computer.
Packaging together Python code into a workable executable file requires that we also include all the dependencies of the program. This is the exact reason why we work with virtual environments. They enable the program to keep all dependencies together so that when we package our code, everything including the Python interpreter is included in the executable so that we don't need to install anything on the victim computer for our program to work perfectly.
