9 Exploring Hash Algorithms

Hash algorithms play a crucial role in malware, and they are often used for various tasks, from checking the integrity of downloaded components to evading detection by changing the hash of a file. In this chapter, we’ll delve into common hash algorithms that are used in malware and provide examples of their implementation. The overarching theme of this chapter is to provide you with a holistic understanding of hash algorithms in the context of malware development. By combining theoretical insights with practical implementations, you’ll gain not only conceptual knowledge but also the skills to apply these principles in real-world scenarios.

In this chapter, we’re going to cover the following main topics:
