Summary

We saw, in this chapter, that QEMU is large and complex software that allows us to emulate different computer architectures, as well as run different systems implemented, thanks to dynamic recompilation (among other available technologies). QEMU has also played a crucial role in the world of cybersecurity as it has allowed the analyst to apply dynamic analysis, as well as fuzzing, to binaries from architectures different from the host architecture they are using (with the performance penalty that QEMU inevitably supposes), but even with its shortcomings, there’s a list of vulnerabilities that were found using this software as the base of the analysis. Finally, we saw that there are ways to interact with QEMU by writing our own code in C for the main software; these plugins allow us to easily interact and manage QEMU with easy-to use programming languages, such as Python. This will be important for future chapters, as it allows us to automate some of the tasks we will...
