Cracking WEP encryption

In this recipe, we are going to learn about WEP encryption cracking. Wired Equivalent Privacy (WEP) is a security protocol, specified in the IEEE Wireless Fidelity (Wi-Fi) standard, 802.11b, and designed to provide a Wireless Local Area Network (WLAN) with a level of security and privacy comparable to what is usually expected of a wired LAN. WEP works on RC4 encryption and has been widely used on the Internet as a part of HTTPS. The flaw here is not RC4 but the way RC4 had been implemented. The problem was the reuse of IVs. For this exercise, we will be using a tool called Wifite. This tool is used to attack multiple WEP-, WPA-, and WPS-encrypted networks in a row. This tool is customizable and can be automated with only ...
