Project 9-2: Substitute a MAC Address Using SMAC

Although MAC address filters are often relied upon to prevent unauthorized

users from accessing a wireless LAN, MAC addresses can easily be spoofed.

In this project, you will substitute a MAC address.

1. Open your web browser and enter the URL www.klcconsulting.net/

smac.

The location of content on the Internet may change without warning.

If you are no longer able to access the program through the above

URL, use a search engine and search for KLC Consulting SMAC.

2. Scroll down to FREE Download SMAC 2.0.

3. Click Download Site 3.

4. When the file finishes downloading, run the program and follow the

default installation procedures.

5. Click Finish to launch SMAC and accept the license agreement.

6. When prompted for a Registration ID, click Proceed. SMAC displays the

network interface card adapters that it discovers, as seen in Figure 9-11.

If the message SMAC has determined that you have insufficient

registry access appears, close the SMAC application if necessary.

Single click on the SMAC icon and then click the right mouse button.

Click Run as administrator.

7. If there are multiple network interface card adapters listed, click on each

adapter. Does the Active MAC Address change? Why?

8. Click on a network adapter and then click the Random button to change

the MAC address. It is displayed in the New Spoofed MAC Address .

9. Click the Random button to create a new MAC address.

10. Click the down arrow under the New Spoofed MAC Address to view the

manufacturer associated with this OUI.

11. Does the OUI change?

12. Click the down arrow under the New Spoofed MAC Address to view the

manufacturers again. Select a different manufacturer. What happens to

the OUI?

13. Click the Random button several more times to create new MAC

addresses based on this manufacturer.

Because this is an Evaluation mode copy of SMAC, you are not able

to actually change the MAC address. In the Full Feature mode, you

would click on Update MAC as the next step.

14. Close all windows.

15. To reenable your originalMAC, launch SMAC and then click RemoveMAC .

16. Reboot the computer.
