CoWPAtty - Brute-force dictionary attack against WPA-PSK. Copyright(c) 2004-2018 Joshua Wright -------------------------------------------------------------------------------- INTRO Right off the bat, this code isn't very useful. The PBKDF2 function makes 4096 SHA-1 passes for each passphrase, which takes quite a bit of time. On my Pentium II development system, I'm getting ~4 passphrases/second. The SHA-1 code I'm using has been optimized to the best of my ability (which isn't saying that much), but I doubt if it would be possible to optimize it such that the tool experiences an exponential performance increase.

However, if you are auditing WPA-PSK or WPA2-PSK networks, you can use this tool to identify weak passphrases that were used to generate the PMK. Supply a libpcap capture file that includes the 4-way handshake, a dictionary file of passphrases to guess with, and the SSID for the network: $./cowpatty -r eap-test.dump -f dict -s somethingclever cowpatty 4.0 - WPA-PSK dictionary attack.

Collected all necessary data to mount crack against WPA/PSK passphrase. Starting dictionary attack. Please be patient. The PSK is 'family movie night'. Gta san andreas download for pc. 4087 passphrases tested in 59.05 seconds: 69.22 passphrases/second $ The files 'dict' and 'eap-test.dump' are included with this distribution for testing purposes. If your SSID has spaces or other non-ASCII characters, enclose it in quotes so the shell doesn't interpret it as multiple parameters.

This tool can also accept dictionary words from STDIN, allowing us to utilize a tool such as John the Ripper to create lots of word permutations from a dictionary file: $ john -wordfile:dictfile -rules -session:johnrestore.dat -stdout:63 cowpatty -r eap-test.dump -f - -s somethingclever In the default configuration of John the Ripper, common permutations of dictionary words will be sent as potential passwords to coWPAtty. For example, here is a list of the words John will create from the input word 'password': jwright@mercury:~$ echo password >word jwright@mercury:~$ john -session:/tmp/delme -wordfile:word -rules -stdout password Password passwords password1 Password1 drowssap 1password PASSWORD password2 password!

Note that it is also possible to mount a precomputed attack against the PSK. The PBKDF2 algorithm used to generate the PMK takes two non-fixed inputs: the passphrase and the network SSID. For a given SSID, we can precompute all the PMK's from a dictionary file with the 'genpmk' tool: $./genpmk genpmk 1.0 - WPA-PSK precomputation attack.
