Summary
In this chapter, we explored the most common attack vectors used by hackers to gain an initial foothold in victim environments, with a particular focus on email-based attacks. We reviewed the different types of email threats and discussed the techniques used by attackers to evade detection and trick their victims into interacting with malicious email content. Additionally, we delved into the anatomy of email secure gateway logs and provided insights on how to investigate email threats effectively.
In the next chapter, we will learn about email flow and header analysis.
