In this chapter, we will focus on the first part of network penetration testing—that is, pre-connection attacks. In order to perform these attacks, we will look at the fundamentals; we will study the concept of sniffing. Once we have a good idea of what sniffing is, we will look at targeted packet sniffing, and an important tool for sniffing—the Wireshark tool. Then, we will launch our first attack: the deauthentication attack. Finally, we will create a fake access point.

In this chapter, we will look at the following topics:

• Packet sniffing basics
• Targeted packet sniffing 
• Deauthentication attacks
• What is a fake access point?
• Creating fake access points with the MANA Toolkit
