In some ethical hacking engagements, you might need to spoof the MAC address of a network interface card. This short list of steps help you do that:
1. Find the name of the interface you want to spoof the MAC of.
ifconfig
You’ll see interface names such as “eth0”, or “ens33”, depending on the Linux distro you’re using.
Note: If this command doesn’t exist, you can install the “net-tools” package through “apt”, “yum” or any other package manager you use.
2. Turn the interface off:
ifconfig ens33 down
Replace “ens33” with your interface name of choice.
3. Update the MAC address:
ifconfig ens33 hw ether 12:34:56:78:90:12
Replace the “12:34:56:78:90:12” with the MAC address of your choice.
4. Turn the interface on:
ifconfig ens33 up
That’s all!
