Kali provides an excellent platform for the discovery, cataloging, and penetration of wireless networks. In this section, we will look at several tools that can be used to scan and discover wireless networks. This process will be instrumental in later chapters as we use the information gathered here to choose our targets and focus our efforts:
Let's look at each of these tools in more detail and show how they can assist with mapping and discovering wireless networks.
Airodump-ng is part of the Aircrack-ng suite used extensively to penetrate wireless 802.11 networks. Airodump-ng captures raw 802.11 frames from the wireless medium in the vicinity; it is also capable of capturing weak IVs (Initialization Vectors) that are used in cracking the WEP key. The output from airodump-ng is saved in several formats (pcap, ivs, csv, gps, kismet, netxml, and so on), which can be analyzed once the scan is finished. Airodump-ng typically...
