What is pixiewps?
Pixiewps is a tool written in C used to bruteforce offline the WPS PIN method(s) exploiting the low or non-existing entropy of some software implementations of the WPS protocol, the so-called "pixie-dust attack" discovered by Dominique Bongard in summer 2014. It is meant for educational purposes only.
This process can reduce the time of finding the correct PIN from hours to a few minutes or seconds. The PIN can later be used to recover the WPA-PSK from the Access Point using a tool like Reaver, Bully or join directly the wireless network using wpa_cli and other programs.
