All right.
So welcome back everyone.
In this section we are going to focus on changing the MAC address of our interface that we are using.
So in this case our interface would be our Wi-Fi card or this network adapter
so you can see that we have a breeze network adopt so why do we need to change our mac addresses.
So in this course we will develop some programs for example earpiece booth which will help us to become
a man in the middle so to perform these attacks you expose your MAC address to the victim machine so
you don't want to do that.
So what you will do is that you will try to change your mac address for the moment.
And once you have that attack is completed you can go back to your normal MAC address.
So masking your mac address will provide you safety security.
It will help you in hiding your identity so before we go in to change creating a program for a changing
of our mac address we will interact with a year of config command in our calling machine.
This command helps you to configure IP addresses are not related activities in your calling machine.
So the first command we are going to use is called a f config.
So before we go into details up I have config first.
Let's see what the private and public IP addresses.
So a private IP address is the one that is used inside your own local network.
And this IP address is not accessible outside your local network.
So this address is something like this for example 1 9 2 1 2 0 0 dot.
And then there would be some number.
So these last two things could change.
For example it could be 15 or something.
But this will mostly remain the same in case of our local black votes.
This could also change it could be one time two for example but most of the time it will be something
like this or 1 9 2 1 6 8 0 that 15 So if you don't see anything like this what you can do is go to this
network adapter settings you can go from here
and once you have this network adapter settings click on this breached condition and check this box
and this will end you.
This would change your IP address to this format.
So you know your IP address will resemble like mine.
So the next thing is a public IP address.
So this is an IP address that is provided to you by your Internet service provider.
Ah yes.
And this is usually static and you cannot mostly change it unless you are using viewpoints a public
IP is used whenever you are interacting with something that is outside your own network.
And if you were interacting with something of some device that is inside your own local network then
you use the MAC address.
Mac stands for media access control and it is used for all the local communication that is happening
inside your own network.
So and similarly IP addresses are used for communication outside of your own network.
So there are ways to hide your identity.
For example you can hide your IP address by using weapons.
Europeans are virtual private networks.
Our programs are softwares that helped you master your identity.
You can buy them and even you can use some free variants.
But most of the time you have to buy this software.
And then in order to change a MAC address.
So since MAC address works inside your own local network so you don't need to pay anything for changing
your MAC address and you can do it locally on your own machine and it helps you to hide your local activity.
So if you are performing some attack in your local network it had to do must be your identity because
you can hide your real MAC address.
So in this section we will build this MAC address.
So before we go into building it let's first check out that I have config Come on.
So I have config is used for finding out your IP addresses IP addresses hardware local interfaces.
So I am currently on Cali 2020 version so this Cali user is not a router user.
So previously in Adley and regions of Cali you could simply write a f config and this would work but
in Cali 2020.
This does not work so you have to use sudo before it.
In order for this command to run properly so you can simply write to the config and press enter and
then it will ask you for parser.
Just provide the password which is godly and now you can see that it print out the IP addresses for
different interfaces so don't worry about this interface.
Just focus on this EPA to Europe.
If you are using Windows it would be different.
It would be something like W LP etc.
But since you're working with Linux it is EDF 0 and I think the same command works in Mac OS as well.
So instead of idiots you know it would be Ian 0 I think.
Okay so now you can see that we have.
This is our private our local IP address so there's 1 9 2 1 6 8 0 22 and then this is your IP 6.
So we will not focus on IP B6 in this course so we will only focus on these two parameters.
So one would be this IP phone address and the other one would be this one which is the MAC address for
this interface this interface is nothing but a physical hardware device that provides you network connectivity
and next lecture we will build a program using I have config and then we will try to change this field
features that you can field
so I'm going to stop here.
