In this chapter, we started by covering the essentials of assembly in the context of exploit writing in Metasploit, the general concepts, and their importance in exploitation. We covered details of stack-based overflows, SEH-based stack overflows, and bypasses for protection mechanisms such as DEP in depth. We covered various handy tools in Metasploit that aid the process of exploitation. We also looked at the importance of bad characters and space limitations.
Now, we are able to perform tasks such as writing exploits for software in Metasploit with the help of supporting tools, determining important registers, methods to overwrite them, and defeating sophisticated protection mechanisms.
In the next chapter, we will look at publically available exploits that are currently not available in Metasploit. We will try porting them to the Metasploit framework.
