Un outil très puissant, comporte plusieurs options permettant de planter un routeur wifi, de flooder un chan entier, et bien plus encore...<br /><br />

[http://homepages.tu-darmstadt.de/~p_larbig/wlan/mdk3-v5.tar.bz2 MDK-3 v5]<br><br>

Pour pouvoir le compiler sous ubuntu (à vérifier pour les autres distributions) il faut installer gcc-2.4 et modifier le fichier mdk3/osdep/common.mak<br />
Remplacer la ligne:<br />
<pre>
CC = $(TOOL_PREFIX)gcc
</pre>
par:<br />

CC = $(TOOL_PREFIX)gcc-4.2

Un petit script très utile pour l'utiliser (créé par MatToufoutu):<br /> [http://www.zonard.net/~mattoufoutu/AP-Fucker.py AP-Fucker.py]<br />
Il permet un "mode destruction" qui lance 4 attaques différentes simultanément.<br />

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.

MDK USAGE:
mdk3 <interface> <test_mode> [test_options]

Try mdk3 --fullhelp for all test options
Try mdk3 --help <test_mode> for info about one test only

TEST MODES:
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.

b   - Beacon Flood Mode                                                  
      Sends beacon frames to show fake APs at clients.                   
      This can sometimes crash network scanners and even drivers!        
      OPTIONS:                                                           
      -n <ssid>                                                          
         Use SSID <ssid> instead of randomly generated ones              
      -f <filename>                                                      
         Read SSIDs from file                                            
      -v <filename>                                                      
         Read MACs and SSIDs from file. See example file!                
      -d                                                                 
         Show station as Ad-Hoc
      -w
         Set WEP bit (Generates encrypted networks)
      -g
         Show station as 54 Mbit
      -t
         Show station using WPA TKIP encryption
      -a
         Show station using WPA AES encryption
      -m
         Use valid accesspoint MAC from OUI database
      -h
         Hop to channel where AP is spoofed
         This makes the test more effective against some devices/drivers
         But it reduces packet rate due to channel hopping.
      -c <chan>
         Fake an AP on channel <chan>. If you want your card to hop on
         this channel, you have to set -h option, too!
      -s <pps>
         Set speed in packets per second (Default: 50)
</pre>
<pre>
a   - Authentication DoS mode
      Sends authentication frames to all APs found in range.
      Too much clients freeze or reset almost every AP.
      OPTIONS:
      -a <ap_mac>
         Only test the specified AP
      -m
         Use valid client MAC from OUI database
      -c
         Do NOT check for test being successful
      -i <ap_mac>
         Perform intelligent test on AP (-a and -c will be ignored)
         This test connects clients to the AP and reinjects sniffed data to keep them alive
      -s <pps>
         Set speed in packets per second (Default: unlimited)
</pre>
<pre>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
      Use -f and -t option to enable SSID Bruteforcing.
      OPTIONS:
      -e <ssid>
         Tell mdk3 which SSID to probe for
      -f <filename>
         Read lines from file for bruteforcing hidden SSIDs
      -t <bssid>
         Set MAC adress of target AP
      -s <pps>
         Set speed (Default: unlimited, in Bruteforce mode: 300)
      -b <character set>
         Use full Bruteforce mode (recommended for short SSIDs only!)
         Use this switch only to show its help screen.
</pre>
<pre>
d   - Deauthentication / Disassociation Amok Mode
      Kicks everybody found from AP
      OPTIONS:
      -w <filename>
         Read file containing MACs not to care about (Whitelist mode)
      -b <filename>
         Read file containing MACs to run test on (Blacklist Mode)
      -s <pps>
         Set speed in packets per second (Default: unlimited)
      -c [chan,chan,chan,...]
         Enable channel hopping. Without providing any channels, mdk3 will hop an all
         14 b/g channels. Channel will be changed every 5 seconds.
      -d [target]
         Enable WPA/WPA2-Downgrade-Attack
         Blocks clients only if they use WPA Encryption, WEP and unencrypted traffic still works
         Use this test to see if the Sysadmin thinks WEP is still enough security when WPA "doesn't work"
</pre>
<pre>
m   - Michael shutdown exploitation (TKIP)
      Cancels all traffic continuously
      -t <bssid>
         Set Mac address of target AP
      -w <seconds>
         Seconds between bursts (Default: 10)
      -n <ppb>
         Set packets per burst (Default: 70)
      -j
         Use the new TKIP QoS-Exploit
         Needs just a few packets to shut AP down!
      -s <pps>
         Set speed (Default: 400)

      0 - EAPOL Start packet flooding
            -n <ssid>
               Use SSID <ssid>

               Set MAC address of target AP

               Set unicast cipher type (1: TKIP, 2: CCMP; default: TKIP)
            -m <multicast cipher>
               Set multicast cipher type (1: TKIP, 2: CCMP; default: TKIP)
            -s <pps>

</pre>
<pre>
w   - WIDS/WIPS/WDS Confusion
      Confuses a WDS with multi-authenticated clients which messes up routing tables
      -e <SSID>
         SSID of target WDS network
      -c [chan,chan,chan...]
         Use channel hopping
      -z
         activate Zero_Chaos' WIDS exploit
         (authenticates clients from a WDS to foreign APs to make WIDS go nuts)
</pre>
<pre>
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
      -t <bssid>
         Target BSSID
      -m <mac>
         Set the MAC adress range to use (3 bytes, i.e. 00:12:34)
         Without -m, the internal database will be used
      -f <mac>
         Set the MAC adress to begin bruteforcing with
         (Note: You can't use -f and -m at the same time)
</pre>
<pre>
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. mdk3 will let WEP and unencrypted
      clients work, so if the sysadmin simply thinks "WPA is broken" he
      sure isn't the right one for this job.
      (this can/should be combined with social engineering)
      -t <bssid>
         Target network
