Bully is a new implementation of the WPS brute force attack, written in C. It is conceptually identical to other programs, in that it exploits the (now well known) design flaw in the WPS specification. It has several advantages over the original reaver code. These include fewer dependencies, improved memory and cpu performance, correct handling of endianness, and a more robust set of options. It runs on Linux, and was specifically developed to run on embedded Linux systems (OpenWrt, etc) regardless of architecture.

Bully provides several improvements in the detection and handling of anomalous scenarios. It has been tested against access points from numerous vendors, and with differing configurations, with much success.

You must already have Wiire's Pixiewps installed. The latest version can be found here:


apt-get -y install build-essential libpcap-dev aircrack-ng pixiewps



git clone


wget && unzip


cd bully*/
cd src/


sudo make install


  usage: bully <options> interface

      -V, --version          : Print version info and exit
      -h, --help             : Display this help information

-d // --pixiewps

The -d option performs an offline attack, Pixie Dust (pixiewps), by automatically passing the PKE, PKR, E-Hash1, E-Hash2, E-Nonce and Authkey. pixiewps will then try to attack Ralink, Broadcom and Realtek chipsets.

-v // --verbosity

The -v option specifies the verbosity of bully. -v 4 now prints all the collected hashes and outputs the pixiewps command run. Default runlevel is 3.


None of this would have happened without the rest of the great team I am proud to credit with helping me: t6_x, DataHead, Soxrok2212, Wiire Huge thanks to wiire for helping remove the openssl dependancy!
