In this chapter, you will learn how to automate the task of looking for vulnerabilities in executable binaries using Ghidra. You will analyze how a Ghidra script developed by Zero Day Initiative works by looking for vulnerable calls to sscanf (a C library that reads formatted data from a string) in order to automate the bug hunting process explained in the previous chapter.
