Wifi 802.11 Management Frames de-auth mass kick exploit

In wifi protocol 802.11, the management frames are barely ever encrypted (even in wpa2), and this allows for anyone to send out management frames (even if you are not connected yourself), mostly de-authentication frames, which can be used to spoof a user disconnecting to the network. This means on most 802.11 networks, that you can kick everyone off of the network, or specific users, for as long as you want. This makes the chosen wifi to attack unusable, as long as the attack is active.


A wifi version with encrypted management frames exists, it is called 802.11w and it fixes all of these problems, however most companies that manufacture wifi chips or routers do not seem to use 802.11w and most wpa2 networks are subject to this attack.


An example of this is a custom portable wifi de-auther (~$20-25) has been made by seytonic and spacehuhn, which can easily take down a network, if you want to buy a physical device pre-built, however it only works with 2.4ghz networks which is a downside.

You can also build a de-auther yourself with nodeMCU chips which cost less (around 5-8$), and there are tutorials on building a de-auther using these chips.

I hope this helped some people into gaining knowledge of the management frames exploit in 802.11 networks and please tell me if I helped you.

I will leave some helpful links below.
