Spoofing a MAC address

June 20, 2008 03:00 by ckincincy

I'm on vacation and the wireless internet access I have is restricted by MAC address.  I initially signed up on my personal PC (not knowing it was MAC address restricted) but needed access on my work PC.

So I went looking for information on masking my MAC address on my work PC to match my personal PC.  Led me to look into the advanced properties of the wireless card, and I found the answer.

As an FYI I have a Dell Wireless 1490 Dual Band WLAN Mini-Card installed.

Step 1:  Go to the device manager (if you don't know how to do this, you don't need to be doing any of this).

Step 2: Expand Network Adapters, Right click your wireless card and click properties.


Step 3: At the next window go to the Advanced Tab and select the "Locally Administered MAC Address"


Step 4: Enter in the value field your custom MAC address, and there is how you do it.

Was pretty happy to find it this easy.

That just goes to show you how little protection using the MAC filtering provides.  To be sure, I'm not saying MAC filtering shouldn't be used...  Each layer of security makes it that much harder for someone to break in to your systems.  And for some hackers having to identify a valid MAC and then reconfiguring their NIC with that MAC might be just enough to nudge them to hack someone else's WAP instead of yours...

Defense in depth.
