How to Change the Mac Address in Kali Linux Using Macchanger

Imagine your computer has a special ID card for connecting to the internet, called a MAC address. It’s like a name tag that tells networks who you are. Sometimes, for privacy or testing, you might want to change this ID. If you’re using Kali Linux, a system made for people who study security and hacking, there’s an easy tool called Macchanger that can help you do this.

In this blog, we’ll show you how to change your MAC address in Kali Linux using Macchanger in a simple, step-by-step way. We’ll explain what a MAC address is, how to use basic commands, and how to make your computer look like it has a new ID.

Change Random MAC Address

First lets change network card's hardware MAC address to a random address. First, we will find the MAC address of the eth0 network interface. To do this we execute macchanger with an option -s and an argument eth0.

macchanger -s eth0

Now the network interface you are about to change a MAC address should be turned off before changing the mac address. Use ifconfig command to turn off your network interface:

ifconfig eth0 down

Now we can change the MAC address of the hardware by using the command

macchanger -r eth0

Once you have executed the command you can finally turn your network interface up

ifconfig eth0 up

Now you can display your MAC by using:

macchanger -s eth0

Change Specific MAC Address:

You can use MAC changer to change MAC of your choice follow the commands

~ ifconfig eth0 down
~ macchanger -m 00:d0:70:00:20:69 eth0
~ ifconfig eth0 up
~ macchanger -s eth0

Follow the same sequence as we did for random change, the only difference is that this time you have your specific MAC address with you. Use -l option to find a MAC address prefix of a specific hardware vendor:

~macchanger -l
