All language subtitles for 8. Preparing Computer To Run Fake Captive Portal

Okay now that we have our website cloned modified and stored in our web server we're ready to go to

the next step which is creating our fake access point.

Now I've covered creating fake access points before I covered how to do that manually use an airbase

N.G. and I covered how to do that using a script that's called mine.

I took it both of these methods are good.

But what I want to show you today is a generic method that's first of all it's a manual method that's

first of all faster than airbase ngi and it's also what man a tool kit uses to generate it's fake access

point.

So why now.

Fluxion wife Fisher and all these scripts rely on the method.

I'm going to show you today to create their fake access points.

The reason why I'm kind of going low level on this is because first of all I want you to understand

how a wireless access point works and how to manually generate one so that in the future if any of these

tools broke and just didn't work or if you had a certain scenario or if you were just in a certain position

where you had to kind of customize your attack then you'll know how to do that yourself without being

limited to these tools.

So before we do anything I just want to give you an overview a simplified version of the components

used in an access point.

So first of all you need a wireless device that will broadcast a signal that's going to broadcast Wi-Fi

signal.

Now we have a wireless interface that's going to do that for us and we're going to use a program called

Host APD.

Now like I said this is the program that's used by Mynah toolkit so literally my tool kit runs this

program in the background to give you to broadcast the access point that it generates Fluxion and all

these other tools also use host APD to create their access point.

So we're basically removing a layer and we're literally going down layer two and we're going to be doing

this manually ourselves through the command prompt.

Then you'll also need a server that will give IP addresses to the client that connects to our fake access

point.

Now you can use a normal DTP server or you can use dnsmasq.

I like to use DNS mask because it's a two in one server because we can actually also use it as a DNS

server to handle DNS requests.

And and our particular example it's going to be very useful because we're going to use it to redirect

any requests that go to any Web site and redirect them to our logon page because we want this to work

as a captive portal so that if people try to go to any Web site they'll end up in our logon page instead

of actually giving them the website that they want.

So we have three main components.

We have a host APD that's going to generate our wireless network.

We have a DHP server that's going to give IPs to the people that connect to this network.

And we have a DNS server that's going to resolve DNS requests and in our example we're going to make

it redirect any request to the IP were our fake log in page is installed.

And that's usually our own IP.

Now let me do this manually and it'll become more clear to you.

So I have my Callimachi in here.

And the first thing that I'm going to do is install DNS mask and host APD.

So I'm going to go on my terminal and I'm just going to do up to get host APD DNS mosque so we've used

this command so many times by now all we have to do is just do apt get install the programs that we

want to install and we're installed and host a PDA which is the program that's going to generate the

wireless network and dnsmasq which is our DNS server and DHP server.

I'm going to hit enter.

And for me they're both already installed so it's not going to solve anything for me but for you it's

going to ask Who do you actually want to install that you're going to have to type why hit enter and

it'll install for you.

What's done with that.

I'm going to connect my wireless adapter through my U.S. port.

I'm going to go to devices.

Us be and make sure that the adapter is selected.

And as you can see mine is already selected.

So if I do it config it should be there now.

As you can see I have Landseer are already there.

So we're good to go.

Now the first step is going to be disable in network manager.

The reason why I do this because he usually manages this interface and it'll prevent it from working

properly and it's prevent it from being used to broadcast a Wi-Fi signal.

So we're going to do a service network manager stop and that's done.

And notice the network icon disappears from here from the top.

Now the next step is actually not a mandatory step.

It's an optional one.

Well I like to do it every time I've done something like this or try to become the man in the middle.

The reason why because I'm going to run a number of commands that's going to enable IP forwarding so

that the packets can flow through my computer without being dropped and it it'll also delete any IP

tables rules that might interfere with what I'm trying to do.

So it's going to flush IP tables.

Remove any redirections any chains that might interfere with packets that might be redirecting packets

to places that they shouldn't go.

So it's literally clearing any firewall rules that might be redirecting packets to somewhere else.

Now by default you shouldn't need to do this because there shouldn't be any rules at all.

But you never know what programs modify and add IP table the rules in the background.

So to be safe we're going to do that.

And I usually started this in a file in a bash script so I can just run it from terminal just to bash

and type in the name of the script.

But for now I'm actually just for the sake of completion I'm going to open it with a text editor and

I'm just going to copy all the commands here so you can see the first command just enables IP forwarding.

The second command will just flush IP tables will flush the table with the lead chains and will enable

forwarding an IP tables.

So again this is optional.

It's not mandatory but it's better to do it to make sure that your IP tables is clear.

There's nothing that's going to interfere with our attack and that it's going to work.

And so that if it fails we'll know it's something it's nothing to do with IP tables.

So I'm just going to paste everything here you can actually paste multi lines.

And as you can see all of them get executed without showing any errors which means that all of them

got executed successfully.

Now so far we actually haven't done anything to generate our fake access point.

We said we have two three main components.

First start fake access point using host APD second started the HGP server and third start DNS server.

We haven't done any of that.

We just stopped our eyeless adapter and then we deleted any rules that might interfere with our attack.

Now in the next lecture I'll show you how to properly configure all of these services start them.

So we have a fully functioning fake access point that people can't connect to and use just like normal

access point.
