Hello back my hackers, for the next several posts i will cover topics about wireless hacking, it should be a series-like post. I start from the basic, the foundation you need to prepare about to be ready for, either you or your Kali Linux. When i mention “Kali Linux” you could prefer to your own hacking OS. Between, i am not a fan nor Kali Linux savvy. It just my preferable OS to conduct any pentesting for myself.

Before executing a pen test I'd like to spoof my address (I know there are other things that has to be done but spoofing my mac address has been giving me issues). Password Kali Linux 2016. Today we will be learning how to hack a WiFi network in which mac address filtering is enabled i.e mac spoofing.

Let’s get started, To become a better Pen-tester, anonymity your self, cover your pentesting action, be undetectable from getting caught. When you noticed word anonymity don’t wondering first complicated things such proxy, vpn or sock whatever. Start from your device, before you wanna do some hack action, cover your Kali Linux a few seconds after it booted.

Is it possible? what I need to do to cover my Kali within a few seconds?

Yes, it is, it was your Media Access Control Address (stands for MAC Address). MAC Address is unique globally identifier to a network devices, it is often referred to as physical address. MAC Address consist of 6 byte binary numbers (48 bits) and written in format like ID:ID:ID:SS:SS:SS. The first 3 bytes are manufacturer ID number which assigned by internet, and the rest 3 bytes are serial number which assigned by the manufacturer.

MAC Address Vs IP Address

MAC Address, as i mentioned earlier it is in other word, your physical identity or supporting for hardware implementation, MAC layer represents layer 2 of the TCP/IP, whereas IP represents layer 3 and it supports software implementation. MAC is manufacturer assigned on every NIC, but doesn’t mean we can not manipulate our MAC Address.

How TO Find Your MAC Address

Finding MAC Address is easy, ifconfig command display your network interface and necessary information or ID on a list. Explore yourself!

How TO Change MAC Address

Luckily, Kali Linux and major hacking OS has built in tools to accomplished that task, it is “Macchanger“. Macchanger is a GNU/Linux tool for manipulating or changing the MAC Address of network interfaces, as it is called, [MAC]Changer. Macchanger are able to:

• Manipulate MAC randomly
• Set specific MAC
• Set MAC of another vendor
• Set different MAC on the same vendor
• Display vendor list
• Display your MAC Address

Macchanger build on CLI and GUI version. The GUI version package is “macchanger-gtk”. In this and most of my tutorial i am only cover command line things.

Lets take a look at macchanger help options display.

Too see list of available vendor and MAC, run the -l options.

Before you set to fake the interface MAC address, make sure to bring it down and run as root user.

• Set MAC randomly:
  
• Set MAC specifically:
  

To check whether your MAC successfully changed or not, if you are in doubt about this tool, run the ifconfig. Explore the rest available options by yourselves. If you are wondering how to reset to my original MAC address then? Don’t be worry bro, macchanger has to do it too. Did you notice option -P ? it is supposed to reset your MAC to original and permanent hardware MAC.

We will get into more detail about wireless hacking series in the upcoming sections. These are the first steps and the foundation in getting all to be ready.

MAC address spoofing is a technique for temporarily changing your Media Access Control (MAC) address on a network device. A MAC Address is a unique and hardcoded address programmed into network devices which cannot be changed permanently. The MAC address is in the 2nd OSI layer and should be seen as the physical address of your interface. Is quickbook desktop 2016 for mac multiuser. 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.

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

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

Use the following command to show the current MAC address:

macchanger –show wlan1
