The permanent MAC Address will be restored to your network adapter after a reboot or you can reset your network adapters MAC address manually. Now use the following command to change your MAC address to a new random MAC Address:Īs shown on the screenshot, Macchanger will show you the permanent, current and changed MAC address. Replace wlan1 with your own network interface. Use the following command to take down wlan1 with iproute2: The ifconfig tool will be replaced by iproute2. This can be done using the following command: MAC Address Spoofingįirst we need to take down the network adapter in order to change the MAC address. The MAC address is in the 2nd OSI layer and should be seen as the physical address of your interface. Macchanger is a tool that is included with any version of Kali Linux including the 2016 rolling edition and can change the MAC address to any desired address until the next reboot. In this tutorial we will be spoofing the MAC address of our wireless adapter with a random MAC address generated by Macchanger on Kali Linux. A MAC Address is a unique and hardcoded address programmed into network devices which cannot be changed permanently. MAC address spoofing is a technique for temporarily changing your Media Access Control (MAC) address on a network device. All you have to do is choose which network address you would like to change, which can be done at the click of a button. The app simplifies the process of changing your computer's address at no cost.
This is pretty much letting the bash shell interpreter know "Hey, there is a function here." and for it to look for open and close braces. MAC Address Changer is a freeware that gives you the freedom to change any Network Interface (NI) on your device. RAND_MAC() is going to be the function declaration. Now I will explain what is going on with this function: Here is the random HWaddr function for bash: #!/bin/bash It isn't perfect and does have some bugs (such as certain generated MACs not being allowed to the device). The following bash shell code is a very basic random HWaddr generator that I created. Well there are a few ways to do this but I will give you my method since I have not seen it included here. I assume that because you are trying to change the HWaddr of your wireless interface, that you are attempting some wireless pentesting and need to spoof your HWaddr.
