MAC Address Spoofing

First we need to take down the network adapter in order to change the MAC address. This can be done using the following command:

ifconfig wlan1 down

The ifconfig tool will be replaced by iproute2. Use the following command to take down wlan1 with iproute2:

ip link set wlan1 down

Replace wlan1 with your own network interface.

Now use the following command to change your MAC address to a new random MAC Address:

macchanger -r wlan1

As shown on the screenshot, Macchanger will show you the permanent, current and changed MAC address. The permanent MAC Address will be restored to your network adapter after a reboot or you can reset your network adapters MAC address manually. Use the following command to restore the permanent MAC address to your network adapter manually:

macchanger --permanent wlan1

You can also spoof a particular MAC address using the following command:

macchanger -m [Spoofing MAC Address] wlan1

macchanger -m XX:XX:XX:XX:XX:XX wlan1

If you receive the following error you need to take down the network interface first before changing the MAC Address (Command: ifconfig wlan1 down):

ERROR: Can’t change MAC: interface up or not permission: Cannot assign requested address

Use the following command to bring up your network adapter with the new MAC address:

ifconfig wlan1 up

Or use the following iproute2 command to bring the wlan1 device back up:

ip link set wlan1 up

Use the following command to show the current MAC address:

macchanger --show wlan1
