Summary
In this chapter, we explored the pivotal role that hash algorithms play in the realm of malware. This chapter encompassed three primary sections, each shedding light on distinct aspects of hash algorithm utilization in the context of malware.
Here, we covered prevalent hash algorithms. You learned how these algorithms function by exploring practical examples implemented in C/C++ and Python 3. The algorithms that were covered included MD5, SHA-1, SHA-256, and others. Each example equipped you with hands-on experience, fostering a comprehensive understanding of these widely used hash functions.
Finally, we took a hands-on approach to demonstrate the practical implementation of hash algorithms in concealing WinAPI calls. Through detailed examples, you learned how hash algorithms can be leveraged to obfuscate function calls, adding a layer of complexity to malware and enhancing its ability to evade detection.
We hope that the trick of hiding WinAPI calls will be useful...
