“Post-Connection Attacks” Previously, all the attacks we discussed pertained to the pre-connection and gaining access phase. In this section, however, we will be focusing on post-connection attacks, which means attacks that can be executed once a connection to the network has been established. It is important to note that the type of network, whether wireless or wired, and the security protocol used by the target, be it WEP or WPA, are not relevant to the attacks we will be discussing. These attacks can be carried out regardless of these factors.
Previously, to intercept wireless traffic, we set our wireless card to monitor mode, enabling the capture of all packets in the air. However, in this section, as we have network access, there is no need to capture all traffic; rather, we only need to capture packets specifically directed to us. Consequently, we will be utilizing managed mode for our wireless card.
This section focuses on the attacks that can be performed once the network has been breached. We will begin by using a tool called netdiscover, which will help us to gather essential information about the network. This tool is used to explore all the clients that are connected to the system. Next, we will learn about Zenmap, which is a more powerful tool than netdiscover and has a better interface. Zenmap is used to collect comprehensive details about all the clients connected to the network. With these tools, we can obtain the necessary information to launch attacks on the network.
