MDK 3.0 v6 - "Yeah, well, whatever"
by ASPj of k2wrlz, using the osdep library from aircrack-ng
And with lots of help from the great aircrack-ng community:
Antragon, moongray, Ace, Zero_Chaos, Hirte, thefkboss, ducttape,
telek0miker, Le_Vert, sorbo, Andy Green, bahathir and Dawid Gajownik
MDK is a proof-of-concept tool to exploit common IEEE 802.11 protocol weaknesses.
IMPORTANT: It is your responsibility to make sure you have permission from the
network owner before running MDK against it.

mdk3 <interface> <test_mode> [test_options]
Try mdk3 --fullhelp for all test options
Try mdk3 --help <test_mode> for info about one test only
b - Beacon Flood Mode
Sends beacon frames to show fake APs at clients.
This can sometimes crash network scanners and even drivers!
a - Authentication DoS mode
Sends authentication frames to all APs found in range.
Too much clients freeze or reset some APs.
p - Basic probing and ESSID Bruteforce mode
Probes AP and check for answer, useful for checking if SSID has
been correctly decloaked or if AP is in your adaptors sending range
SSID Bruteforcing is also possible with this test mode.
d - Deauthentication / Disassociation Amok Mode
Kicks everybody found from AP
m - Michael shutdown exploitation (TKIP)
Cancels all traffic continuously
x - 802.1X tests
w - WIDS/WIPS Confusion
Confuse/Abuse Intrusion Detection and Prevention Systems
f - MAC filter bruteforce mode
This test uses a list of known client MAC Adresses and tries to
authenticate them to the given AP while dynamically changing
its response timeout for best performance. It currently works only
on APs who deny an open authentication request properly
g - WPA Downgrade test
deauthenticates Stations and APs sending WPA encrypted packets.
With this test you can check if the sysadmin will try setting his
network to WEP or disable encryption.
