Have you ever thought of blocking some Wi-Fi signals or just kicking someone out from a Wi-Fi connection.
Well this is the right place and the right video.
We're going to create a simple Wi-Fi jammer that is so tiny that it can fit into your pocket and you
can carry it anywhere.
Just by powering it up through a simple power bank or even your mobile phone.
So first of all you need to go to Ali Express and search for node MCU
and then you'll be presented by these results.
Just click on the first one which is a wireless module node MCU version 3 MCU actually stands for microcontroller
unit.
It's a small computer on a single see or integrated circuit.
And actually this device is used to prototype I.T. products and applications.
It can act as a client as a server and as a wireless device.
At the same time as per the description on the Node MCU website it is an open source interactive programmable
low cost simple smart Wi-Fi enabled device.
They do authentication.
Attack is the main application that we are going to build on this chip.
This attack will show you how vulnerable the eight or two point one 1 Wi-Fi standard is.
Lady authentication attack is used to disconnect devices from their Wi-Fi network and it's a huge vulnerability
in the official eight or two point one why Wi-Fi standard in 2009 the Wi-Fi Alliance.
They actually fix this problem in the eight or two point eleven W standard.
They increase the security by providing data confidential confidentiality of management's frames the
added mechanisms that enable data integrity and data authenticity and replay attack protections.
However a majority of the access points and clients are vulnerable to this attack.
So just need to purchase this from our Express.
After that you just connect this device to your laptop using the USB B cable and after that you need
to go to this site here and install the USB connectivity driver.
This is very important.
You need to see this in the device manager so it should tell you on which port it's connecting.
After that you can go to the website.
The oath not an E and here is an online interactive step by step tutorial on how to set up the node
MCU.
It will ask you first.
Let's go to the first page here.
If you were a novice or expert just press novice here it will tell you that you need to download this
bean file.
Just click it here and it will do not automatically it will actually download it from the get hub.
You can see the latest releases of the file and download the latest release.
Let's go back for the site here.
Press next.
Select the operating system you using and to press here as well to download the Flash software the Flash
software will help you upload the bent file or populate the firmware on the Node MCU device.
Just press next.
Select the word that the board is on use press next and you'll be presented with a step by step on how
to upload the firmware you need to open the flasher let's open it here.
Notice that I'm connected.
The device is connected to com a boy.
You go to config and select the location for the file just select that and press an open let's press
next here.
It is telling us to press an operation stop and press on the flash button.
Next you go here.
Select the committee port and then press on the flash button.
It will take some time to upload the firmware and once you see this checkmark it means that the firmware
has been uploaded successfully.
Couple of things you need to take care of.
Before doing that is to go to the advanced tab here and use the defaults that you can see on the chip.
Now when things are in place you need to connect to this Wi-Fi a society here named Poland.
So let's do that.
Open the Wi-Fi here and this is the newly created society.
Click pwned and press connect you'll be prompted to enter a password for the first time.
Let's go here.
The author just click next.
And you'll be connected to the pwned network.
Now we need to go to this IP here one man to the 16 a dot for the one
and you'll be presented with the application that we have just populated on the Node MCU.
Couple of things that we need to know here.
The first stub is used to scan all the neighboring Wi-Fi connections so dispersal scan apps.
Once you do that you will notice that the blue LCD light will turn on.
It will take a couple of seconds and then it will turn off once it turns off.
Just press on the reload here you will get all the neighboring Wi-Fi networks.
After that you select one access point.
I'm doing this on my connection here and may jail.
Then select or press on the scan stations button again.
The blue LED on the chip will turn on.
It will take 15 seconds to scan the stations that are connected to this access point.
June the scanning of the stations you will be disconnected from the porn network.
So after this scanning is complete.
Make sure to connect it again to the phone network.
Press on the reload button here and go down to the stations section.
Press on select all.
So we're selecting all the stations that are associated with this access point.
Then go to the attacks menu.
You'll be seeing three types of attacks.
The authentication attack beacon attack and the probe.
As for the authentication attack which is the main application and the tutorial here we have selected
six targets.
So once we start here pressing this time it will start sending the authentication frames to all these
six targets.
So none of these six targets will be able to connect the strip runs on 2.5 gigahertz all the clients
running on 2.5 gigahertz will be disconnected and all the clients running for example on the 5 gigahertz
they will not be affected by this attack.
So I will show the effect of this attack on a client that is connected to the email network.
Okay guys so I am here on another laptop I'm connected to this access point to a module and I'm using
Google and there is an Internet connection and it's working fine.
OK.
Now I will initiate the authentication attack from the node MCU and just notice what will happen in
a while.
Just switch for a couple of seconds and you will see that there is a yellow mark here which obviously
says that there is no Internet connectivity so let's check it out here.
Just do this for refresh says there is no Internet access.
So again it's identifying the network connected so let's hit refresh again.
It's connected but actually the authentication packet disconnected this client again from the access
point.
So this can go on forever depending on the configuration.
Going back again to the other types of attack we have the beacon and the probe.
If you go down below you'll be able to see the description of the probe attack is actually just to mimic
clients sending probe requests to me by SS I.D. which are like fake probably quests.
This is actually done just to confuse some Wi-Fi trackers.
The other attack we'll talk about here is the beacon attack.
So actually it creates false societies.
If you go here to the SS I.D. menu you have two options to create false SS I.D. you can either select
an SS I.D. name here and just select the number of access points that you will be creating press on.
And if you go below here you'll be able to see all of these random SS I.D. no go through the attacks
menu Press Target next to the beacon.
The notice here on the network you will be able to see a lot of fake access points.
Again you can go to the SS I.D. can enable the random mode which actually creates a list of just random
access points with these naming conventions.
As you can see again go to the attacks menu and start could be an attack again.
Let's check now and you will see a list of these random access points available for us to connect to.
