There are sniffers that can analyze packets that travel through the network and / or encrypt them. The information captured from traffic can be imported into other tools that we may have, such as an aircrack-ng cracker. Unlike wireless network scanners, sniffers go one step further by capturing information about APs, which is used to analyze the packets that are transmitted over the wireless network. It also has sniffer functions that capture packets, inject and reproduce traffic, and, of course, it is capable of cracking access passwords, depending on whether enough packets have been captured for it (in the case of WEP), or if you have captured the handshake in the case of WPA / WPA2. In addition, you can view the access points that are close to you, including those that have hidden or unavailable SSID. It is compatible with Windows, Mac OS X, Linux and OpenBSD. On the other hand, Aircrack-ng is an open source suite of tools to crack WEP and WPA / WPA2 keys and is beginning to update for WPA3 networks. It is free and lists all the WEP, WPA and WPA2 keys that were stored on your Windows computer at some point. WirelessKeyView is a tool that can support you. It also highlights how important it is to use 802.1x type authentication where users have individual access credentials for the Wi-Fi network, especially in the corporate environment or in places where this connectivity is offered as a service or facility. The importance of these tools lies in the fact that they reveal how a compromised or stolen device can contain a lot of sensitive information, in addition to various documents or files. Tools that show other details of the wireless network
