and control your network interfaces. As you have seen, with {i | ༺ HACKING ༻

and control your network interfaces. As you have seen, with {interface} down,
you told your network adapter (in this example identified as eth0) to shut off. In
this way, you can use the macchanger command to generate a random value (using the -r parameter) and apply it to the eth0 network adapter. Once you
complete these steps, reactivate your adapter using the ifconfig {interface} up
command. Feel free to replace the ifconfig command with the newer ip
(iproute2) one. In case of connectivity issues, you can also restart using the
command:
$ service network-manager restart
Although this operation is quite easy, you can find different scripts online to
automatize the entire process. Here are some:
• SpoofMAC (https://github.com/feross/SpoofMAC)
• spoof (https://github.com/feross/spoof)
In the Windows environment (Figure 2), you can choose among different
options, such as directly changing the settings through the following path:
Control Panel -> System -> Hardware -> Device Management -> Network
Adapters -> Adapter name -> *right-click* -> Properties -> Advanced -> Net
Address -> Value:

NB: this feature may be missing on some network adapters, because it is
made available at the discretion of the manufacturers and according to the
existing drivers.
However, the above feature can be used through many tools available online.
If you have some spare time, you may want to try one of the following:
• MacMACs (https://www.irongeek.com/i.php?page=security/madmacs-
mac-spoofer)
• Win7 MAC Address Changer (http://www.zokali.com/win7-mac-address-
changer)
• Technitium MAC Address Changer (https://technitium.com/tmac/)
• Change MAC Address (http://lizardsystems.com/change-mac-address/)
• mac-spoofer (https://github.com/angusshire/mac-spoofer)
On macOS, changing the MAC Address of an Ethernet network adapter is a
relatively easy task. You only have to run the following commands:
$ sudo ifconfig en0 ether aa:bb:cc:dd:ee:ff
$ sudo ifconfig en0 lladdr 00:11:22:33:44:55
When it comes to a WiFi adapter, things get more complex. In this case, you
have to patch your kernel

, but you should try it only if you feel confident
enough with the Apple world.
If such practice is too complicated for you, but you still wish to work in the
Mac OS environment, consider purchasing an external USB device, and you will
be able to do the MAC Spoofing easily, as you’d do with the Ethernet adapter.
