Wireless deauthentication

What’s it about?

I want to impersonate the gateway of a wireless network or another pc connected to the wireless network, without being connected to that network, in order to trick computers connected to it into doing what i want. First thing that i thought about was kicking them out, cloning theyr MAC and gaining access (this would be useful for networks with mac filters, radius servers etc).

Why?

– It’s fun

– I get a chance to see how wireless network work at a very low level (low as in very deep, you get my drift).

How?

Firstly, i wanted to know what happens when somebody disconnects from a wireless network.

I started my wifi-card into monitoring mode :

iw dev wlan0 interface add wlan0-mon type monitor
ifconfig wlan0-mon up

I fired up Wireshark and set it to monitor the new monitoring wireless interface (wlan0-mon) and i clicked on the disconnect button the see what happens

The “attack” plan:

Description:

– the big round container is the wireless coverage of the existing wireless network (not the real coverage but i wanted to point out that all the devices in the diagram are in the wireless range of the router)

– my pc isn’t connected to the wireless network or to any other device

– my pc is telling the router that a pc in the network is disconnecting by injecting the raw frames that are sent when somebody wants to disconnect

– the router will deauthenticate the victim pc thinking that it was the one who wanted to disconnect

– the MACs and IPs are totally random (except for the MAC from my PC) to show the idea, and will not be linked to screenshots and such
