This chapter mainly focuses on implementing attacks on the external network. For that, we need to know what port forwarding is, so in this chapter, we are going to get an idea of what we need to do to access the victim's machine through the router. Until now, we have been focusing on internal backdoors; now we are going to look at external backdoors. We will then look at the concept of IP forwarding, which plays another important part in attacking from outside the local network. We are also going to look at examples to gain a clear understanding of this concept, wherein we will hook our system to the external BeEF browser.
In this chapter, we will be covering the following topics:
- Port forwarding
- External backdoors
- IP forwarding
- External BeEF
