All language subtitles for 010 Netcat-subtitle-en

During the section we will be talking about some tools in Linux that is very very useful in penetration

testing not just Android penetration testing but any platform penetration windows Android clinics anything.

And one of the best tools that I'm going to start to is it's called the netcat and netcat.

We usually we usually refer to a hacker Swiss Army because of the amount of function and task it can

execute.

So we're going to see how to utilize netcat and do not trash the result I mean later on you're going

to see how you can utilize this knowledge in different attack.

So netcat it's a tool belt in Linux that can do many many feature.

It can open a port it can connect to a port it can scan it can transfer files between different machines

so if you'd know how to utilize the tools it will really facilitate your penetration testing Pask.

So let's see how to use that.

Let's start with the Linux machine.

I have it to machine.

I have a Windows machine and a linux machine.

One that could be Windows 7 Windows 8 Wonderstone whatever and windows just this Uzodinma that I have

in front of me but it doesn't matter what operating system you are using in Linux and that that is built

in well in Windows.

It's an external tool.

So let's open a terminal and let's see how to use that get netcat can be used by typing and see OK.

And if you need to know the difference which allow you to use netcat how to scan how to open a prototype

netcat minus help sorry and it will show you all the steps around sort of all the switches that can

be used.

Users of netcat and each switches doing what and so on.

So let's take a small example about that.

First I want to show you that I already have a Windows netcat.

This is an external tool I mean it's not built in in windows in Linux it's already built in.

But in Linux I download it from the internet and I put it inside a folder here.

Which was.

This is netcat but to be able to use the net get from any place from any command line.

I'm going to copy this netcat and put it inside the windows folder and by doing that I can open a command

prompt and use it right away.

So will take first a small example of using netcat.

Then we're going to see how to utilize that in a different way.

This is a Windows folder.

Let me co-presented get here just to be able to use it from the command prompt and then let's see.

So here we have two different computer the Linux computer IPs 1 9 2 1 6 8 2 2 1 2 1 0 9 and the windows

computer as a Windows computer is 1 0 9 1 0 in his computer.

I think once you reach the config.

And as you can see it is 1 0 8.

So let's do a small example on how to utilize netcat.

So from the windows machine I'm going to type and see netcat minus N..

This is for listening.

So I'm asking.

Then cat to listen from a port then VI.

This is verbose so everything will be clear while it's executing and then p.

Which is the port number and I can choose any port in my case I'm going to choose port 5 5 5 5 for instance.

And as you can see the open port 5 5 5 and start listening and waiting for the connection and from my

Linux machine let me just clear the screen.

I can type and see and then the computer IP 1 9 2 2 1 6 8 8.

Sorry netcat and 1 9 2 1 6 8 200 1 0 9 and support number from where it will be connected because what's

going on here.

Is a Windows machine open a port which is 5 5 5 and this machine will connect to the sport and one two

three four.

And let's see what will happen.

It will take a few seconds and here we go.

We have a connection between those two machine.

Now just to test that we can just type anything here.

I and it will shows that and you can reply from here as well.

And it will.

It's not about that.

You are doing that to Type-I and high.

But the thing is that you are able to create a connection between those two computer later on you can

see how can you change files between them.

How can you execute.

Comment and so on.

And as a way for testing the if the connectivity are there or not if you open another terminal and you

type net state net the minus in and verifies that the connection took place you should find the port

which is 5 5 5 5.

So you should find a connection between the two machine one and two and six it to and 0 8

it's just small.

So it's not easy to check but it should be easier especially trigs establish to an established connection.

So should be one of those.

Yes.

Here you go.

So this is on new.

Now what I'm saying is because this is going so it shows that there is a connection between those two

computer Supai it's sort of part 5:5.

Now how can we utilize that that can be utilized in different ways that we're going to see in different

examples in the upcoming video.

I can use that get to know some program what program are running on different part or what protocol

ironical different people I can use that get to change find between the two computer.

I mean if I can upload in NC five netcat fine to any victim machine I can use that to connect to his

machine and transfer between those two devices transfer files.

I can use netcat to execute comment on remotely on different machine.

So what I wanted to know so far is how to use the basic command of netcat and Gooding's upcoming lessons.

You'll learn how to utilize that in a better way.
