WiFi Dictator

Keeps Leeches At Bay

I was at a coworking space the other day and had massive troubles with slow internet. After looking over a couple of shoulders I realized that half of the crowd was watching Miley Cyrus videos on YouTube in full HD while the other half was seemingly downloading the very same videos. I got so pissed off that I went into rage mode and started to deauthenticate all of the people (except me of course) by hand. I wrote a dirty script to do this every minute. Unfair, I know. Then I thought I have to write something that would only kick the leeches who stream video or download torrents. I found a script that is doing exactly that. I modified it to automatically detect interfaces, MAC address etc..

The script puts your interface into monitor mode and inspects the network traffic with Airodump-ng. The results are written into a CSV file. Then it parses the CSV and grabs the MAC addresses of clients who are being stupid. The "stupidity" threshold is based on packet count over a defined period (Default is 200 pakets in 5 seconds, you might need to play with this a bit). We use some AWK fun to get this info, then launch Aireplay-ng to inject our deauth frames, and we'll also go ahead and spoof the MAC of the base station, because connected clients tend to ignore deauth frames not coming from there.

If you're having driver problems, I feel bad for you son. I got 99 chipsets but Broadcom ain't one.
