Why someone would build such a weapon I do not know, but in this example, we will focus on the more commonly seen Wi-Fi security camera.

You can run this from a virtual machine, a live USB install, or a hard drive installation. Next, you'll need a wireless network adapter that allows for packet injection and monitor mode, since you'll need be able to scan the area to locate the device you wish to disconnect. You'll also need to send packets that pretend to be from the access point the device is connected to.
With those two requirements taken care of, you can get started by making sure your system is fully up to date. In Kali, the command to do can be seen below. After this, you should be ready to go, but make sure you have a target you have permission to access and deny service to with the Aireplay-ng tool. While you can scan any network you want with Kismet, Aireplay-ng will execute a denial-of-service attack that is illegal to run against a network you don't have permission to audit.
Theories of testing
The first step in identifying wireless targets is to conduct passive recon on the wireless environment. To do this, we can use a program called Kismet which can perform wireless signals intelligence in a passive and undetectable fashion. The advantage of this is that by simply being in proximity to your target, you can observe the wireless traffic in the area and later parse the information to find interesting devices.
An alternative to Kismet is running Arp-scan , which can be configured in a number of ways to filter information further about the networks you discover.

While this does work, sometimes the output takes more work to decipher. We'll be using Kismet, however, for the rest of this guide. To start scanning with either tool, we'll need to put our wireless network adapter into monitor mode.

We can do so by typing the following, assuming wlan0 is the name of your wireless card. You can get the name of your wireless card by running ifconfig or ip a to list the available network interfaces. Once the command runs, you can run ifconfig or ip a again to confirm the card is in monitor mode.
It should now be named something like wlan0mon. In this command, we are specifying which network adapter to use with Kismet with the -c client flag. We should see something like the output below. You can press Tab , then Return , to close the console window and show the main screen.
We can now scroll through the network and attempt to identify interesting devices. If you can't do this, you may need to enable more options under the "Preferences" menu to see the source of packets. You can access this through the "Kismet" menu seen below. Once Kismet is running, you can start to look up the manufacturer of any devices that look like they might be a security camera. Here, we have found a likely device, which Kismet tells us is made by "Hangzhou.
We can look into this in more detail due to the way that MAC addresses are assigned.
Because the first six numbers and letters are assigned to a particular organization, I was able to quickly look up the name of the company that makes this device along with "A Taking the full name of the company, in this case, Hangzhou Hikvision Digital Technology, a simple Google search reveals their product line.
As luck has it, they are a company that makes wireless surveillance cameras. You can press Ctrl-C to close Kismet. It's worth noting that if a security camera only starts to record or send data when it sees motion, a hacker could sit nearly a mile away and just record when the camera is sending traffic to know when someone is moving in front of the camera, even if they couldn't see what the camera was seeing directly.
With all this information, a discovery like a door being monitored by a streaming camera connected to a DVR would mean that we can expect the device to stop functioning when disconnected. We can take all of the information we found and use Aireplay-ng to disable the connection. I am using my WiFi network adapter on the laptop to connect to the internet on Ubuntu I have tried the following steps and got the below messages on the Ubuntu terminal.
Please let me know what has gone wrong. Thank you. Type ifconfig wlan0 and press Enter. You will not see any output in the terminal, as this command just turns your wireless card on. Most wireless cards are designated wlan0. If yours has a different designation, use that instead. Type iwconfig wlan0 essid name key password and press Enter. Replace name with the actual network name, and replace password with the actual security key for the network.
If your wireless network does not require a security key, do not enter key password. This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question. Okay, I'm going to try and answer your question, even though there is no terminal output included in your question.
The command ifconfig wlan0 does not turn on your wireless card. It gives you information about your wlan0. To turn on your wireless card, you would enter ifconfig wlan0 up. Although, it's not always wlan0.
To find out the name of your wireless card, type iwconfig , and look at the row that has some information in it, not 'no wireless extensions'. So, you have to put the word sudo before those commands unless you're already logged in as root. The password in the command iwconfig wlan0 essid name key password should be in hexadecimal.
