MAC spoofing

As we have learned, spoofing is simply tricking the target into believing traffic or a request is originating from another device or a trusted source. Both IP and MAC addresses can be spoofed quite easily since the TCP/IP protocol suite was not designed for modern-day security threats.

Note

To prevent MAC address spoofing within a network, network security professionals can implement Dynamic ARP Inspection (DAI) on Cisco IOS Switches.

To generate and assign a random MAC address to an interface, we must do the following:

1. Logically turn down the interface using the ifconfig wlan0 down command:

2. Verify the current and permanent MAC addresses on the specified interface using the macchanger –-show wlan0 command:

3. Use the macchanger --random wlan0 command to generate and assign the MAC to our wlan0 interface:

4. Re-enable the interface using the ifconfig wlan0 up command:

Note

Additionally, you can use the macchanger –-help command to view all the options available.

You will obtain the following...
