So from the previous lecture we know in order to crack debut epee we need to first capture a large number
of packets.
This means that we'll capture a large number of babies.
The Ivy is because they are assured they will be repeated.
Therefore we'll be able to use a tool called aircraft energy to run statistical attacks and crack the
web key.
So we use an aero dump engine to capture the data and we see how to do this before then we are using
aircraft engines to analyze this data and break the key.
Let's see how to do this in practice.
So I already have my wireless adapter in WANT TO mode.
It's called Zero.
I've also already run aero dump energy to list all the networks around me.
And as you can see I have on you are NetWare cuz inaudible you epee.
This is called Test AP 3 and this is my actual network that I use every day.
I just configure it to use web to make this lecture.
The main reason why I'm telling it in the network that I use daily because like I said for this to work
we need to capture a large number of packets and therefore we need a busy network a network that gets
used constantly to capture a large number of packets.
If the network is idle then the process is a little bit complex.
And I will cover that in the next lecture.
So for now let's focus on the simplest form which is how to break into a busy network.
So I'm going to copy the B.S. this idea of this network.
I'm going to try and erode the energy against this network on the.
So I showed you how to do this before I'm going to do air or dump energy.
I'm going to do a dash dash yes you to specify the BSA side of the network.
Then I'm going to do a dash dash channel to specify the channel of the network and we can see it's running
on number one.
And I'm going to do dash dash right to store everything that we capture into our file and that's called
this file basic web.
And then I'm going to specify in my wireless set up to monitor mode which is more than zero.
So we run this command before in the targeted sniffin lecture.
All we're doing is we're on an Aero energy against a specific network with this address with this channel
and were storing everything in a file called basic web.
I'm going to have a..
And as you see error dump Energy is working and guess my target network.
And if you notice you'll see the data in here is increasing really really fast.
So this is something that I told you I'll talk about it later when we were talking about error dump
engine because I didn't want to talk about ivie's that early stage.
So basically what you see under the data column is the number of useful packets that contain a different
i.v that we can use in order to crack the key.
So the higher the number is the more likely we will be able to crack the key.
As you can see this number is increasing very fast because like I said this is a busy network that is
being used at the moment by my own computers and my own devices.
If yours is increasing at first then don't worry.
We will tackle this problem in the next lecturers.
So for now we're capturing a lot of data and this should actually be enough to crack the key.
So what I'm going to do I'm going to go down to my other terminal here and if we actually list the files
you'll see that we have the capture of file that we specified in the right argument.
And like I said we're always interested in the dot Cup file.
So all we have to do right now is do a step two in here.
Right.
Erica like engy against the file that we captured in order to crack the key.
So I'm going to do Eric right.
Energy.
Followed by the file name which is basic Webster are one dot cap.
I'm going to hit enter.
And as you can see it's tough on us.
The key is found.
So let me counsel this here.
And right now we can connect to the targeted network which is called Test AP three years in this key
password so you can literally just copy this and pasted or you can connect you as in this key.
Now in some cases you will not see this as key password.
That's why I'm going to show you how to connect as in this key right here because you're always get
this.
So I'm going to copy this.
And I'm just going to paste it here.
You can post it anywhere in a normal text editor or anywhere you want.
And all you have to do is a more of the call that we see in here between the numbers.
So I'm going to add more.
This one and this and this and this.
And now we can just copy this.
Just to show you I'm actually going to connect from my host machine.
He can connect from candy bar when we enable monitor mode we killed all our processes and sometimes
even after you restart these processes getting connected to your tag it will be a little bit buggy.
So it's best to literally just restart Carly and connect again.
So just to save all of this time I'm going to connect from here.
I'm just going to click here.
I'm going to Kinect to test AP and go on to paste the password.
So I'm just going to click on Sure the password to show it to you again the same password.
We just remove the columns.
I'm going to click on Join in.
And as you can see we managed to connect.
We can test this connection by go to Google.
Effect.
As you can see it's working.
And we managed to break the E.P. encryption.
