Reaver has been designed to be a robust and practical attack against Wi-Fi Protected Setup (WPS) registrar PINs in order to recover WPA/WPA2 passphrases. It has been tested against a wide variety of access points and WPS implementations.
The original Reaver implements a online brute force attack against, as described in http://sviehb.files.wordpress.com/2011/12/viehboeck_wps.pdf. reaver-wps-fork-t6x is a community forked version, which has included various bug fixes and additional attack method (the offline Pixie Dust attack).
Depending on the target's Access Point (AP), to recover the plain text WPA/WPA2 passphrase the average amount of time for the transitional online brute force method is between 4-10 hours. In practice, it will generally take half this time to guess the correct WPS pin and recover the passphrase. When using the offline attack, if the AP is vulnerable, it may take only a matter of seconds to minutes.

apt-get -y install build-essential libpcap-dev sqlite3 libsqlite3-dev aircrack-ng pixiewps
The example uses Kali Linux as the Operating System (OS) as pixiewps is included.
You must already have Wiire's Pixiewps installed. The latest version can be found here: https://github.com/wiire/pixiewps.

Required Arguments:
-i, --interface=<wlan> Name of the monitor-mode interface to use
-b, --bssid=<mac> BSSID of the target AP
Optional Arguments:
-m, --mac=<mac> MAC of the host system
-e, --essid=<ssid> ESSID of the target AP
-c, --channel=<channel> Set the 802.11 channel for the interface (implies -f)
-o, --out-file=<file> Send output to a log file [stdout]
-s, --session=<file> Restore a previous session file
-C, --exec=<command> Execute the supplied command upon successful pin recovery
-D, --daemonize Daemonize reaver
-a, --auto Auto detect the best advanced options for the target AP
-f, --fixed Disable channel hopping
-5, --5ghz Use 5GHz 802.11 channels
-v, --verbose Display non-critical warnings (-vv for more)
-q, --quiet Only display critical messages
-K --pixie-dust=<number> [1] Run pixiewps with PKE, PKR, E-Hash1, E-Hash2 and E-Nonce (Ralink, Broadcom & Realtek)
-Z, --no-auto-pass Do NOT run reaver to auto retrieve WPA password if Pixiewps attack is successful
-h, --help Show help
Advanced Options:
-p, --pin=<wps pin> Use the specified 4 or 8 digit WPS pin
-d, --delay=<seconds> Set the delay between pin attempts [1]
-l, --lock-delay=<seconds> Set the time to wait if the AP locks WPS pin attempts [60]
-F, --fake-delay=<seconds> Set the time to sleep after received fake NACK [0]
-R, --fake-reason=<nack reason> Specifies the reason code for NACK used in the FAKE NACK
-I, --ignore-reason Ignore change of reason code for NACK
-g, --max-attempts=<num> Quit after num pin attempts
-x, --fail-wait=<seconds> Set the time to sleep after 10 unexpected failures [0]
-r, --recurring-delay=<x:y> Sleep for y seconds every x pin attempts
-t, --timeout=<seconds> Set the receive timeout period [5]
-T, --m57-timeout=<seconds> Set the M5/M7 timeout period [0.20]
-A, --no-associate Do not associate with the AP (association must be done by another application)
-N, --no-nacks Do not send NACK messages when out of order packets are received
-S, --dh-small Use small DH keys to improve crack speed
-L, --ignore-locks Ignore locked state reported by the target AP
-E, --eap-terminate Terminate each WPS session with an EAP FAIL packet
-n, --nack Target AP always sends a NACK [Auto]
-w, --win7 Mimic a Windows 7 registrar [False]
-X, --exhaustive Set exhaustive mode from the beginning of the session [False]
-1, --p1-index Set initial array index for the first half of the pin [False]
-2, --p2-index Set initial array index for the second half of the pin [False]
-P, --pixiedust-loop Set into PixieLoop mode (doesn't send M4, and loops through to M3) [False]
-W, --generate-pin Default Pin Generator [1] Belkin [2] D-Link [3] Zyxel
-H, --pixiedust-log Enables logging of sequence completed PixieHashes
Example:
reaver -i wlan0mon -b 00:90:4C:C1:AC:21 -vvv -K 1
The -K 1 option performances the offline attack, Pixie Dust (pixiewps), by automatically passing the PKE, PKR, E-Hash1, E-Hash2, E-Nonce and Authkey variables. pixiewps will then try to attack Ralink, Broadcom and Realtek detected chipset.
Special note: If you are attacking a Realtek AP, do NOT use small DH Keys (-S) option.
The -H option is a switch to enable logging of PixieHashes, saved hashes will be saved in the executing directory.
This option requires you to have at the least -vvv switch on and will work with -K 1 & -P appropriately.
The files saved are named after the bssid (MAC) of the target, and with an extention of .pixie.
On the inside of these saved logs, you will find all the required PixieDust hashes, along with a quick copy & paste ready full command to use it on pixiewps. You also have the option to execute it. Just pop in the file into your favorite shell, and execute it (chmod +x <filename> may be required).
When using the -P option, Reaver goes into a loop mode that breaks the WPS protocol by not using M4 message to hopefully avoid lockouts.
This is to ONLY be used for PixieHash collecting to use with pixiewps, NOT to brute force 'online' pins.
This option was made with intent of:
- Collecting repetitive hashes for further comparison and or analysis / discovery of new vulnerable chipsets, routers etc..
- Time sensitive attacks where the hash collecting continues repetitively until your time frame is met.
- For scripting purposes of whom want to use a possible lockout preventable way of PixieHash gathering for your use case.

Required Arguments:
-i, --interface=<iface> Interface to capture packets on
-f, --file [FILE1 FILE2 FILE3 ...] Read packets from capture files
Optional Arguments:
-c, --channel=<num> Channel to listen on [auto]
-o, --out-file=<file> Write data to file
-n, --probes=<num> Maximum number of probes to send to each AP in scan mode [15]
-D, --daemonize Daemonize wash
-C, --ignore-fcs Ignore frame checksum errors
-5, --5ghz Use 5GHz 802.11 channels
-s, --scan Use scan mode
-u, --survey Use survey mode [default]
-P, --file-output-piped Allows Wash output to be piped. Example. wash x|y|z...
-g, --get-chipset Pipes output and runs reaver alongside to get chipset
-h, --help Show help
Example:
wash -i wlan0mon
The option -g of Wash, automatically runs Reaver to receive the chipset data.
If the AP does not respond to them quickly, this option will be slow to display the data, because Reaver will stay running until it receives the data or until you reach your timeout limit (30 seconds).
