Spoofing your MAC Address

This is a tutorial on how to spoof your MAC address.

The first thing we need to do is figure out what network devices are install on your box. To do this we open up a shell in backtrack and run the following commands.

::command that displays current active network interface configurations.

ifconfig

::output suppressed for the ifconfig command
lo
eth0

:: command to check for your wireless network interfaces that exist in your box

iwconfig

::output suppressed for the iwconfig command

wlan0

::lets say we don't care about using our ethernet card represented by eth0 and just want to jump in using our wireless card wlan0. The first thing that needs to be done is shutdown your interface to use the macchanger program.

::this command will shut down our wireless card interface

ifconfig wlan0 down

::this command will spoof the MAC to a random MAC on interface wlan0 (our wireless card)

macchanger -r wlan0

::output

current MAC 00:11:12:3D:54:9C
spoofed MAC 00:AA:BB:CC:34:FF

::the last step in the this process is to turn the wireless card back on and verify the our MAC has changed

ifconfig wlan0 up

ifconfig wlan0

::output suppressed

MAC 00:AA:BB:CC:34:FF

WALA you now have a spoofed MAC and ready to connect to the wireless network with different MAC address which is untraceble.

Enjoy!
