If you’re looking to keep your online identity anonymous, a step in the right direction would be to change the unique MAC address of your computer every time you connect to a network.
Change the MAC address: Change the MAC address of your network interface. You can manually input the MAC address or generate a random one. Profile manager: You can save the MAC address to profile and use it later. This will save your time. History manager: When you change the MAC address, the log will be saved here. The first step in spoofing your MAC address is to find the network interface device that you want to spoof. Go to StartControl PanelNetwork Connection. Then double click on the device that you want to spoof. Then click on the support tab and then click on details. Then in the list you will see the MAC.

This is especially useful if you’re constantly on the move and you connect to networks from different locations like cafes and airports.
What is a MAC address?
This should go without saying, but just to clarify this from the get-go: a MAC address has NOTHING to do with macOS.
MAC = media access control. A MAC address of a device is a unique identifier assigned to a network interface controller.
A computer for example usually has two unique MAC addresses. One is for Ethernet and the other for Wifi.
When you try to connect to a Wifi, your laptop will broadcast its MAC address as it searches for a wireless network to connect to.
Manufacturers keep lists of MAC addresses of all the devices they’ve built. So buying a laptop with your own credit card will make it possible to link your purchase to a unique MAC address. Unlikely, but possible.
Also if someone wants to track your MAC address, it would be easy to trace your movements because your laptop reveales its location every time it communicates with a wireless network.
According to Edward Snowden, the US National Security Agency has a system that tracks the movements of mobile devices in a city by monitoring MAC addresses. To avert this practice, Apple has started using random MAC addresses in iOS devices while scanning for networks. Other vendors followed quickly. MAC address randomization during scanning was added in Android starting from version 6.0, Windows 10, and Linux kernel 3.18. The actual implementations of the MAC address randomization technique vary largely in different devices. Moreover, various flaws and shortcomings in these implementations may allow an attacker to track a device even if its MAC address is changed, for instance its probe requests’ other elements, or their timing. If random MAC addresses are not used, researchers have confirmed that it is possible to link a real identity to a particular wireless MAC address.
Using wireless access points in SSID-hidden mode (network cloaking), a mobile wireless device may not only disclose its own MAC address when traveling, but even the MAC addresses associated to SSIDs the device has already connected to, if they are configured to send these as part of probe request packets. Alternative modes to prevent this include configuring access points to be either in beacon-broadcasting mode, or probe-response with SSID mode. In these modes, probe requests may be unnecessary, or sent in broadcast mode without disclosing the identity of previously-known networks.

HOW TO SPOOF YOUR MAC ADDRESS ON macOS
1. First let’s see what’s your MAC adress. Open up a terminal shell and type:
ifconfig en1 | grep ether | awk '{print $2}'
NOTE: usually en1 is Wifi, en0 is ethernet. If unsure, run
ifconfig
in the terminal and check which one is active. ( if you’re connected to WiFi, en0 which is ethernet will say “inactive” and viceversa )2. Install Homebrew ( click on homebrew to learn how to install and use it ). If already installed move on.
3. Install SpoofMAC via Homebrew. In the terminal type
brew install spoof-mac
4. Once installed type
spoof-mac --help
to learn how to use it.5. To randomize your MAC address type
sudo spoof-mac randomize en1
or sudo spoof-mac randomize wi-fi
.NOTE: You won’t get any output. You will know that it worked because you will be disconnected from wifi and will have to reconnect. Also you can run the command from the first step and confirm your MAC address changed.
NOTE: if you’re running an older version of macOS ( or OS X, whetever you want to call it ) you might need to replace “wi-fi” with “airport”. so
sudo spoof-mac randomize wi-fi
becomes sudo spoof-mac randomize airport
6. You can also set your MAC adress to something specific. To do this type
sudo spoof-mac set 00:00:00:00:00:00 en1
( replace 00:00:00:00:00:00 to your desired address )7. To reset your MAC address you need to type
spoof-mac reset wi-fi
OR just restart your computer. macOS does not store MAC address changes between restarts.8. If you want run SpoofMAC at startup run this in terminal:
# Download the startup file for launchd
curl https://raw.githubusercontent.com/feross/SpoofMAC/master/misc/local.macspoof.plist > local.macspoof.plist
# Customize location of `spoof-mac.py` to match your system
cat local.macspoof.plist | sed 's|/usr/local/bin/spoof-mac.py|`which spoof-mac.py`|' | tee local.macspoof.plist
# Copy file to the OS X launchd folder
sudo cp local.macspoof.plist /Library/LaunchDaemons
# Set file permissions
cd /Library/LaunchDaemons
sudo chown root:wheel local.macspoof.plist
sudo chmod 0644 local.macspoof.plist
By default, the above will randomize your MAC address on computer startup. You can change the command that gets run at startup by editing the
local.macspoof.plist
file:sudo nano /Library/LaunchDaemons/local.macspoof.plist

HOW TO SPOOF YOUR MAC ADDRESS ON Linux
1. First, you need to figure out what your wireless or ethernet network is named. To do that, in a terminal shell run
ifconfig
or ip addr
NOTE: if you’re running
ifconfig
and get “command not found” you need to install “net-tools”.2. Install ‘macchanger’. The package should be availble in your distro package manager or you can install it via terminal by typing
sudo pacman -S macchanger
OR sudo apt-get install macchanger
OR equivalent for your distro.3. Once installed, run macchanger –help to learn how to use it.
4. To show your current MAC address run
macchanger enp0s3 -s
. To assign a new and random MAC address, run sudo macchanger enp0s3 -r
.NOTE: change ‘enp0s3’ accordingly to reflect your setup.
NOTE: if you get the following error
[ERROR] Could not change MAC: interface up or insufficient permissions: Device or resource busy
you will have to take your interface down, change address then take it back up like this:sudo ifconfig enp0s3 down && sudo macchanger enp0s3 -r && sudo ifconfig enp0s3 up
( change ‘enp0s3’ accordingly to reflect your setup )NOTE: on some distros, during macchanger installation you will be prompted with the following screen asking you if you’d like to automatically change your MAC address every time your network interface goes online.
Chooce <Yes> and you’re set. Otherwise you either need to create a script to run it at startup or a bash alias. Your MAC address will reset to factory on each reboot.
HOW TO SPOOF YOUR MAC ADDRESS ON Windows
Most network cards allow you to set a custom MAC address from the config panes in Device Manager.
- Open Device Manager and under “Network adapters” right click on the network interface that you want to modify, and select properties.
2. In the properties window, select the “Advanced” tab. In the “Property” list select the “Network Address” entry. Enable the “Value” option and type your new MAC address without separating the characters ( no dashes or colons ). Click “OK” and you’re done.
NOTE: If you don’t see the “Network Address” entry in the “Property” list, then your network driver does not support this feature.
This article discusses the MAC address, including how to spoof your system’s MAC address. This article will show you which steps are important to consider while changing the MAC address of your device. In addition, we will discuss some of the key instructions and proper guidance for changing the MAC address. First, we will start with a basic definition of the MAC address.Media Access Control (MAC) Address
The MAC address, also known as the Media Access Control address, is the unique and separate hardware number of a particular computer, especially in a LAN (Local Area Network) or other network. When connected to the internet as a host or your computer is connected to the Internet, the IP address of your computer is linked to the physical MAC address of the computer on a LAN. A MAC address is similar to an Ethernet address on the Ethernet LAN. In telecommunication protocols, the media access control, which is the sublayer of the data-link layer, uses the MAC address.
Changing the MAC Address with macchanger in Kali Linux
To follow this tutorial to change the MAC address in Kali Linux by using macchanger, the following points are important to consider:
Key Objective
The key objective of this article is to change the real hardware MAC address of the network’s card. This article will show you how to change the MAC address with the help of macchanger in Kali Linux.
Main Requirements
The main essential requirement is to have authorized access to a system having Kali Linux.
Level of Difficulty
The difficulty level must be easy.
Protocol
# (needs to execute given Linux commands with authorized roots, instead of using the sudo command, or needs to be done directly by the root user)
$ (involves the execution of given Linux commands as the non-authorized user)
Key Instructions
The following key instructions will be included in this tutorial:
- Changing the MAC address to a random MAC address
- Checking the new MAC address
- Changing the MAC address to a specific MAC address
Change the MAC Address to a Random MAC address
In the first step, we will use macchanger to change the hardware MAC address of the network card to a random address. We will investigate the current MAC address by taking the eth0 network interface. By doing so, we will able to execute the macchanger with the argument eth0 and the option -s.
The network interface must be turned off before changing the MAC address. The command ifconfig is used to turn off the interface of the network. This command is shown below:
If you have failed to turn off the network interface, then the following error message will be displayed:
ERROR: Can’t change MAC: interface up or not permission: Cannot assign requested address
Now, we will change the hardware MAC address of the network card to different hexadecimal numbers. You can do so by entering the following command:
Mac Spoofing Attack
Finally, bring up the network interface and show your new MAC address by entering the following commands:
Check the New MAC Address
After listing the network interface with the help of the ifconfig command, the new MAC address will be shown.
Change the MAC Address to a Specific MAC Address
Spoof Mac Address Mac
To change the MAC address to a specific string in Kali Linux, use the following method. This can be done with the help of macchanger’s -m option. The commands for changing the MAC address to a specific address are given below:
