Overview

Reaver implements a brute force attack against Wifi Protected Setup (WPS) registrar PINs in order to recover WPA/WPA2 passphrases, as described in Brute forcing Wi-Fi Protected Setup When poor design meets poor implementation. by Stefan Viehböck.
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 and has been tested against a wide variety of access points and WPS implementations.
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.

The first version of reaver-wps (reaver 1.0) was created by Craig Heffner in 2011.
reaver-wps-fork-t6x version 1.6.x is a community forked version which includes various bug fixes, new features and additional attack method (such as the offline Pixie Dust attack).

The original Reaver (version 1.0 to 1.4) can be found in google code archives.
The discontinued reaver-wps-fork-t6x community edition, reaver version 1.5.3, which includes the Pixie Dust attack, is now the old-master branch from this repository.
The latest revison of reaver-wps-fork-t6x community edition is the master branch from this repository.
Reaver versioning was updated to 1.6.x in order to identify the new cycle.
All stable relases since the first beta version of reaver 1.6 can be downloaded from our Releases page.
More information about the Pixie Dust attack (including which APs are vulnerable) can be found in pixiewps repository, [pixie dust thread in Kali forum)](https://forums.kali.org/showthread.php?24286-WPS-Pixie-Dust-Attack-(Offline-WPS-Attack) & Dominique Bongard's full disclosure

Requirements

Build-time dependencies

libpcap-dev
build-essentials

Runtime-time dependencies

pixiewps (optional, required for pixiedust attack)
aircrack-ng (optional, though recommended)

Example

sudo apt -y install build-essential libpcap-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 to perform a pixie dust attack, latest version can be found in its official github repository.

Options description and examples of use can be found in the Readme from Craig Heffner. Here comes a description of the new options introduced since then:

-K or -Z // --pixie-dust

The -K and -Z option perform 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. User will have to execute reaver with the cracked PIN (option -p) to get the WPA pass-phrase. This is a temporary solution and an option to do a full attack will be implemented soon

-p with arbitrary string // --pin=

See our wiki: Introducing a new way to crack WPS: Option p with an Arbitrary String
