Spoofing MAC addresses

To change your MAC address using Kali Linux, you can use a tool called
macchanger , and use the following command:

macchanger [-hVeaArls] [-m,--mac,--mac= MAC_ADDRESS] INTERFACE

Following is an example of macchanger in action:

ifconfig down eth0
macchanger –-mac=01:02:03:04:05:06 eth0
ifconfig up eth0
