A Media Access Control address (MAC address) is a unique identifier assigned to network interfaces for communications on the physical network segment.
MAC addresses are most often assigned by the manufacturer of a network interface card (NIC) and are stored in its hardware, the card's read-only memory, or some other firmware mechanism. If assigned by the manufacturer, a MAC address usually encodes the manufacturer's registered identification number. It may also be known as an Ethernet hardware address (EHA), hardware address, adapter address, or physical address.
Steps for spoofing MAC address:-
1. Download the SMAC tool from the below link.
Download SMAC
2. Unzip the program into its default directory.
3. Start the program from the Windows Start, Programs menu.
4. Open a DOS prompt and type ipconfig /all. Record your MAC address or write it somewhere.
5. Now use the SMAC program to change your MAC address. If you would like to change your MAC to a specific value, you could sniff it from the network or you could the table at http://standards.ieee.org/regauth/oui/index.shtml to research specific Organizational Unique Identifiers (OUIs) at the IEEE website.
6. Once you have determined what to use for a new MAC address, enter it into the SMAC program; then save the value and exit.
7. Finally reboot the system and perform the ipconfog /all command from the DOS prompt. Record the MAC address here and compare to the results in step 4.
You should see that the two MAC addresses are different.
What is the use of it?
This is a value that can be used to demonstrate the trivial process of MAC spoofing and can be used to bypass controls that lock down networks to systems that have an approved MAC address.
