Hello everybody and welcome back.
Now in this lecture we will come on our first program that we will use which is called Mach changer.
It allows us to change our mac address which can be used for multiple things such as for example if
on a particular by wireless network.
There is a blacklist or white list which is based on the MAC addresses.
You can bypass that with simply changing your MAC address.
Now a program that we will use is called Mac change.
If you just type here in the terminal Mac changer you will notice that it will print the usage of the
command.
So here it is.
We need to change your options and then the device.
Now in order to check out our available options we can type here as it says try Mac change their dash
help.
So we will type Mac changer test help and we will basically show us right here some of the available
options that we can use right now in order to find out what our mac addresses.
We want to use this option which is minus minus or dash this show or minus us.
Now if we just type here Mac changer minus it people say that we incorrectly used this program because
we didn't specify the device.
Now this device basically means your network interface card you might be having multiple interface cards
so we want to pick one if you type here.
I have config as we called in the previous Toros.
It will print you up with your network interfaces here.
I only have look like interface.
And the H O interface with the which I use to connect to the Internet.
So I will use this one if I just repeat the command changer minus X and then 88 Joe it will print out
my current MAC address and my permanent back address with it which in this case are both the same because
we didn't change it yet.
Now if you have multiple interfaces just pick the one you use currently and just specify it at the end
the command now Let's type here it once again the iMac changer.
Does that help in order to see what else we can do with this program.
So we cover this part which is show showing our current MAC address.
Now let's say we want to change the MAC address.
We can look some of the options here.
It says set fully random MAC address which we can do with the minus r or dash dash random.
So let's try to put the random MAC address and see what happens if we type here.
Mac changer minus r which stands for this option right here which is set for the random MAC address
and then we specify once again our network interface we can see that right now our MAC address is changed
as you can see right here.
New Mac is this one the previous one was this one.
So if we want to show our mac address again we we can see that it has changed.
Oops I forgot to specify the interface.
We can see that the current MAC address is a different one from the permanent one and we can see it
we successfully changed the MAC address but let's say for example you want to bypass the white list
of the MAC addresses you would want to specify a specific MAC address so we can do that with this command
which is basically dash dash Mac and then specifying a MAC address let's say for example we want the
MAC address.
Let me just open another terminal right here.
Let's say we need to have this MAC address right here
we can try to get it with the minus command.
We just move this right here.
So if we run once again Mach changer minus we will go dash dash Mac.
Now we will set here.
The MAC address here.
We will put equal I'm not sure if we need to put equal rights here.
We will try that first and then 2 2 3 3 4 4 5 5 6 6 7 7 and then we will specify our network interface.
So if we see right here it's changed our Mac to the specific MAC address that we wanted it changed too.
So right now once again if we type Mac change or minus minus show.
Now it is like this.
Yes I always forget to specify the network interface.
We can see that our current MAC address is 2 2 3 3 4 4 5 5 6 6 7 7 and our permanent Mac is our normal
MAC address which doesn't really change oh yes if we want to we can reset back to the original permanent
hardware MAC with the minus B comment.
Now if you're finished with your attack for example and you want to change this IP address back to the
let me just type here again to the normal and not IP address MAC address to the normal MAC address which
is our permanent MAC address you can do that with minus B command.
So let's try that Mac change your minus peak and then our network interface and we can see that the
new Mac is now the same as the permanent Mac.
And now we are back to normal.
We can just type your show again and we are the same as we started before using this program and this
is a useful program in for you to change MAC address.
You can even put it to change it at the boot up of this machine.
So it changes basically every time you restart the machine it will change your mac address which can
be used to provide a little bit of anonymity.
But I to use that you can if you want to.
And that's about it for this program.
It is one of the simple ones.
So we covered it first in the next lecture we will cover a Google hacking which is also pretty simple.
So I'll show that in the next lecture and I hope I see you there and they can.
