A MAC address is the unique identity of the user who tries to authenticate over a wireless network. Often as a best practice users prefer to Mac-filter their networks to protect themselves from attackers; however it is very easy to change a Mac address and attack the network. In this recipe, we are going to see how one can change the Mac address of a wireless card.
A wireless card and a Kali machine are required to perform this exercise. In this recipe, we will scan the available network and the devices connected to it, after which we will change the Mac ID of the wireless card to that of the host connected to the network.
