MAC Addresses for Beginners
In the above video, I demonstrate how easy it is to manually change your MAC address, but what even is a MAC address? A MAC address is a unique identifier given to the Network Interface Controller. of a computer. Unlike IP addresses, they don't change when you change your IP with a VPN. This can be problematic because you can still be tracked by your MAC address if someone is determined enough to find out who you are. No worries though, as you can see, it's really not that hard to change your MAC!
Why Change Your MAC?
Most people probably shouldn't even try to change their MAC address, there is really no point in it unless you either really value your privacy, or you are a hacker of some sort. For hackers though, changing your MAC address can give you more access to a Network that they wouldn't normally have if they were to change MAC to a MAC on the network (known as MAC spoofing). Not only can you get more access, but it makes it easier to escalate your privileges easier than if you didn't spoof your MAC. Just remember that unless you have explicit permission to hack a network, it is ILLEGAL to do so!
Process of Changing Your MAC
In the video, I demonstrate very clearly how to change your MAC address manually, but there are also programs that are already written that can change your MAC address for you, instead of you having to enter the commands on the command line every time that you want to change your MAC. You can find a lot of MAC changing programs on Github. For example, here is a Github repository of a MAC changer you can use to manipulate your own MAC!
Takeaway
The takeaway of this post is that, in reality, most people will never have to change their MAC, or even want to for that matter, but for hackers, changing their MAC addresses can provide them with easier access to whatever network they are trying to hack and possibly allow them to escalate their privileges or transverse the network easier.
