README

# MDK4

MDK is a proof-of-concept tool to exploit common IEEE 802.11 protocol weaknesses.

# About MDK4

MDK4 is a new version of MDK3.

MDK4 is a Wi-Fi testing tool from E7mer, ASPj of k2wrlz, it uses the osdep library from the aircrack-ng project to inject frames on several operating systems.
Many parts of it have been contributed by the great aircrack-ng community: Antragon, moongray, Ace, Zero_Chaos, Hirte, thefkboss, ducttape, telek0miker, Le_Vert, sorbo, Andy Green, bahathir, Dawid Gajownik and Ruslan Nabioullin. THANK YOU!

MDK4 is licenced under the GPLv3 or later.

# ATTACK MODE

ATTACK MODE b: Beacon Flooding
Sends beacon frames to show fake APs at clients.
This can sometimes crash network scanners and even drivers!
ATTACK MODE a: Authentication Denial-Of-Service
Sends authentication frames to all APs found in range.
Too many clients can freeze or reset several APs.
ATTACK MODE p: SSID Probing and Bruteforcing
Probes APs and checks for answer, useful for checking if SSID has
been correctly decloaked and if AP is in your sending range.
Bruteforcing of hidden SSIDs with or without a wordlist is also available.
ATTACK MODE d: Deauthentication and Disassociation
Sends deauthentication and disassociation packets to stations
based on data traffic to disconnect all clients from an AP.
ATTACK MODE m: Michael Countermeasures Exploitation
Sends random packets or re-injects duplicates on another QoS queue
to provoke Michael Countermeasures on TKIP APs.
AP will then shutdown for a whole minute, making this an effective DoS.
ATTACK MODE e: EAPOL Start and Logoff Packet Injection
Floods an AP with EAPOL Start frames to keep it busy with fake sessions
and thus disables it to handle any legitimate clients.
Or logs off clients by injecting fake EAPOL Logoff messages.
ATTACK MODE s: Attacks for IEEE 802.11s mesh networks
Various attacks on link management and routing in mesh networks.
Flood neighbors and routes, create black holes and divert traffic!
ATTACK MODE w: WIDS Confusion
Confuse/Abuse Intrusion Detection and Prevention Systems by
cross-connecting clients to multiple WDS nodes or fake rogue APs.
ATTACK MODE f: Packet Fuzzer
A simple packet fuzzer with multiple packet sources
and a nice set of modifiers. Be careful!
ATTACK MODE x: Poc Testing
Proof-of-concept of WiFi protocol implementation vulnerability,
to test whether the device has wifi vulnerabilities.
It may cause the wifi connection to be disconnected or the target device to crash.

# Usage

mdk4 [attack_options]
mdk4 [attack_options]

Try mdk4 --fullhelp for all attack options
Try mdk4 --help for info about one attack only

FULL OPTIONS:

ATTACK MODE b: Beacon Flooding
Sends beacon frames to generate fake APs at clients.
This can sometimes crash network scanners and drivers!
-n
Use SSID instead of randomly generated ones
-a
Use also non-printable caracters in generated SSIDs
and create SSIDs that break the 32-byte limit
-f
Read SSIDs from file
-v
Read MACs and SSIDs from file. See example file!
-t
-t 1 = Create only Ad-Hoc network
-t 0 = Create only Managed (AP) networks
without this option, both types are generated
-w
Select which type of encryption the fake networks shall have
Valid options: n = No Encryption, w = WEP, t = TKIP (WPA), a = AES (WPA2)
You can select multiple types, i.e. "-w wta" will only create WEP and WPA networks
-b
Select if 11 Mbit (b) or 54 MBit (g) networks are created
Without this option, both types will be used.
-m
Use valid accesspoint MAC from built-in OUI database
-h
Hop to channel where network is spoofed
This is more effective with some devices/drivers
But it reduces packet rate due to channel hopping.
-c
Create fake networks on channel . If you want your card to
hop on this channel, you have to set -h option, too.
-i
Add user-defined IE(s) in hexadecimal at the end of the tagged parameters
-s
Set speed in packets per second (Default: 50)

ATTACK MODE a: Authentication Denial-Of-Service
Sends authentication frames to all APs found in range.
Too many clients can freeze or reset several APs.
-a
Only test the specified AP
-m
Use valid client MAC from built-in OUI database
-i
Perform intelligent test on AP
This test connects clients to the AP and reinjects sniffed data to keep them alive.
-s
Set speed in packets per second (Default: unlimited)

ATTACK MODE p: SSID Probing and Bruteforcing
Probes APs and checks for answer, useful for checking if SSID has
been correctly decloaked and if AP is in your sending range.
Bruteforcing of hidden SSIDs with or without a wordlist is also available.
-e
SSID to probe for
-f
Read SSIDs from file for bruteforcing hidden SSIDs
-t
Set MAC address of target AP
-s
Set speed (Default: 400)
-b
Use full Bruteforce mode (recommended for short SSIDs only!)
You can select multiple character sets at once:
* n (Numbers: 0-9)
* u (Uppercase: A-Z)
* l (Lowercase: a-z)
* s (Symbols: ASCII)
-p
Continue bruteforcing, starting at .
-r
Probe request tests (mod-musket)

ATTACK MODE d: Deauthentication and Disassociation
Sends deauthentication and disassociation packets to stations
based on data traffic to disconnect all clients from an AP.
-w
Read file containing MACs not to care about (Whitelist mode)
-b
Read file containing MACs to run test on (Blacklist Mode)
-s
Set speed in packets per second (Default: unlimited)
-x
Enable full IDS stealth by matching all Sequence Numbers
Packets will only be sent with clients' addresses
-c [chan,chan,...,chan[:speed]]
Enable channel hopping. When -c h is given, mdk4 will hop an all
14 b/g channels. Channel will be changed every 3 seconds,
if speed is not specified. Speed value is in milliseconds!

Specify an AP ESSID to attack.
-B
Specify an AP BSSID to attack.
-S
Specify a station MAC address to attack.
-W
Specify a whitelist station MAC.

ATTACK MODE m: Michael Countermeasures Exploitation
Sends random packets or re-injects duplicates on another QoS queue
to provoke Michael Countermeasures on TKIP APs.
AP will then shutdown for a whole minute, making this an effective DoS.
-t
Set target AP, that runs TKIP encryption
-j
Use the new QoS exploit which only needs to reinject a few packets instead
of the random packet injection, which is unreliable but works without QoS.
-s
Set speed in packets per second (Default: 400)
-w
Wait between each random packet burst (Default: 10)
-n
Send random packets per burst (Default: 70)

ATTACK MODE e: EAPOL Start and Logoff Packet Injection
Floods an AP with EAPOL Start frames to keep it busy with fake sessions
and thus disables it to handle any legitimate clients.
Or logs off clients by injecting fake EAPOL Logoff messages.
-t
Set target WPA AP
-s
Set speed in packets per second (Default: 400)
-l
Use Logoff messages to kick clients

ATTACK MODE s: Attacks for IEEE 802.11s mesh networks
Various attacks on link management and routing in mesh networks.
Flood neighbors and routes, create black holes and divert traffic!
-f
Basic fuzzing tests. Picks up Action and Beacon frames from the air, modifies and replays them:
The following modification types are implemented:
1: Replay identical frame until new one arrives (duplicate flooding)
2: Change Source and BSSID (possibly resulting in Neighbor Flooding)
3: Cut packet short, leave 802.11 header intact (find buffer errors)
4: Shotgun mode, randomly overwriting bytes after header (find bugs)
5: Skript-kid's automated attack trying all of the above randomly :)
-b
Create a Blackhole, using the impersonated_meshpoint's MAC address
mdk4 will answer every incoming Route Request with a perfect route over the impersonated node.

Set speed in packets per second (Default: 100)
-n
Target this mesh network
