Another additional tool that we're going to explain during this section is called either cap now is

or Issaka it's just different to H-1 or amazing tool that sniffer kept traffic so it captures traffic

going out and in from the device.

Now before explaining Issaka you should understand that we need when we plan to compromise a system

there is different way for doing that we can try to compromise the device itself.

And this what will be explained in the Android tracking section or we can compromise the traffic.

So sometimes the device is hard to compromise.

And my objective is to capture the username and password so I don't have to spend time and effort trying

to compromise device because it has a lot of security for instance.

So what I can do I can wait until the user log into Lipsyte.

So when he tried to log into a website like Facebook or Twitter or any Web site he's definitely going

to send a username and password.

And I can now try to capture them if they are sent over wired or if they are sent wireless.

Same concept apply.

So my point is you can try to to to to compromise a device or you can try to compromise the traffic

or you can try to gain access to information from the traffic.

So let me show you it's a cap and let me tell you how it works.

And then actually it's a big program it need a course by itself.

But I'm going to go through the basics and I'm going to show you a proof of concept and I'm going to

let you try to surf around and check this application.

It's one of the best Sniffen application actually it's a free open source and free.

And one of the tools in this area now to two runs is are cap from Kennedy-Nixon it to go to sniffing

tool and in sniffing you're going to find it's a cap minus sheet or you can type these are kept minus

Captain Z and it will get you the same program.

So once you start there is some steps to do it first.

Actually I'm going to close it and I'm going to open it one more time from the command line so you'll

be aware of the different way of running Issaka.

So you can open a terminal in

and you can type easier care minus capital G runs a graphical interface.

Because if you didn't put the switch it runs the command line and it runs a circuit.

Now this one or is this application.

It can be used for capturing the traffic between different devices so I can capture the traffic between

one device and the router is trying to connect to the Internet through the router and try to logon using

username and password and the traffic is going through the router.

I'm interested to go the traffic going from this machine to this route or I can intercept all the machine

all the traffic in the network going to the router or going anywhere.

But the main advantage of this tool is not just the Sniffen part because you'll find a lot of programs

that do that.

The main advantage of this too is that it can change so it cannot just intercept.

It can change.

So for instance I'm sending an email to someone so the program can intercept this email and he can change

the content of that email.

Someone is going to a specific Web site and intercepting this traffic.

And I'm really directing to another website.

So the main advantage of this program is not just just that is intercepting traffic and by the way we

are calling this attack man in the middle attack because it's actually a man in that you are staying

between two different device seeing the traffic going in between those two device.

So as I was saying zoom in Adventureland of this program is that you are not just intercepting and seeing

and capturing information but you also can can change of them.

So we're going to go through the basic In this letter.

But on the next election I'm going to show you how it can intercept and it can change as well.

So once you open the program

you can see you know it is a different option here.

The first thing you need to do is to go to sniffer and to choose the first one which is choosing from

which traffic you need to sniff for.

So if you click here you're going to see that he can sniff from the network traffic from the Internet

which is why our network traffic.

So if this computer is connected to a wired network he will only sniff for the traffic and says well

why what if I'm using a wireless network.

So you need to click here and you're going to find the name of the wireless is a double zero.

So because my machine doesn't have a wireless right now the colonics.

But if your have a wireless connection you should find the tablet zero and you have to click on this

one that Rylands zero.

So you'd be sniffing and intercepting wireless network wireless traffic.

And by the way how do I know the name of because you may find this thing different than your machine.

How do you know the name of the interfaces or the name of the network adapter.

It's easy.

You can just right click here to the terminal and type I ifconfig.

And when you type I f config you'll see the name of the interface so the interface that I'm using right

now is zero.

If I had a wireless interface you will find it 0 0 and IP for each one of those.

But right now I only have wildmen.

Again what I'm doing right now I'm just going through the basics of the program and next letter I'm

going to show you a demonstration how it can intercept and change traffic.

And I'm going to let you navigate and explore these tools because it's an amazing tool.

Once I specify from which interface I need to capture traffic.

The second part would be to go to host and Troost can host.

So I'm asking him.

OK.

We decided to sniff for the network inside as well to sniff out the traffic inside your wired network.

OK.

So I want to see how many machines we have in this little ten machine 20 machine five machine.

And as you can see down here he starts scanning and he finds five machine inside the letter.

So I specified the interface.

I ask him to scan how many machines do we have then going back to the house and ask him show me how

machine host this and he can show us all the IP mission.
