Cracking WEP encryption
In this recipe, we are to learn about WEP encryption cracking. Wired Equivalent Privacy (WEP) is a 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 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 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 a few arguments. Wifite aims to be the "set it and forget it" wireless auditing tool.
Getting ready
For this activity, we will require wifite (preinstalled in Kali), an active and running wireless adaptor, and a wireless router running WEP encryption.
