Summary
In this chapter, we saw the basic structure of the most common executable formats you will encounter in your tests. There are others but you should now have at least an idea of how executable formats work and how to approach an unknown format. We saw how to look into the structure of a program without having the source code and how to use this knowledge to bypass basic security mechanisms.
In the next chapter, we will add everything we learned in this chapter to what we learned in the previous chapter to allow us to dig into the program's behavior while it is executing, allowing us to bypass some more complicated security schemes.
