Many enterprise networks deploy PSK-based authentication mechanisms for WPA\/WPA2 since it is much easier than establishing the necessary RADIUS, supplicant and certificate authority architecture needed for WPA-Enterprise authentication. coWPAtty can implement an accelerated attack if a precomputed PMK file is available for the SSID that is being assessed.<\/p>\n<h2>coWPAtty Usage<\/h2>\n<p>Example:<\/p>\n<pre>.\/cowpatty -r eap-test.dump -f dict -s somethingclever<\/pre>\n<p>Full Output:<\/p>\n<pre>cowpatty -h\r\ncowpatty 4.6 - WPA-PSK dictionary attack. <jwright@hasborg.com>\r\n\r\nUsage: cowpatty [options]\r\n\r\n    -f  Dictionary file\r\n    -d  Hash file (genpmk)\r\n    -r  Packet capture file\r\n    -s  Network SSID (enclose in quotes if SSID includes spaces)\r\n    -c  Check for valid 4-way frames, does not crack\r\n    -h  Print this help information and exit\r\n    -v  Print verbose information (more -v for more verbosity)\r\n    -V  Print program version and exit<\/pre>\n<script async src=\"https:\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-3033787195489589\"\r\n     crossorigin=\"anonymous\"><\/script>\r\n<!-- Darknet Responsive Post Ad Links [previously link ad unit] -->\r\n<ins class=\"adsbygoogle\"\r\n     style=\"display:block\"\r\n     data-ad-client=\"ca-pub-3033787195489589\"\r\n     data-ad-slot=\"5456620019\"\r\n     data-ad-format=\"auto\"><\/ins>\r\n<script>\r\n     (adsbygoogle = window.adsbygoogle || []).push({});\r\n<\/script>\n<p>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.<\/p>\n<pre>john -wordfile:dictfile -rules -session:johnrestore.dat -stdout:63 | \\\r\n   cowpatty -r eap-test.dump -f - -s somethingclever<\/pre>\n<p>In the default configuration of John the Ripper, common permutations of dictionary words will be sent as potential passwords to coWPAtty. <\/p>\n<p>This tool is based around the whitepaper by Robert Moskowitz:<\/p>\n<p><a href=\"https:\/\/wifinetnews.com\/archives\/2003\/11\/weakness_in_passphrase_choice_in_wpa_interface.html\">Weakness in Passphrase Choice in WPA Interface<\/a><\/p>\n<p>There are also the following to check out:<\/p>\n<p>&#8211; <a href=\"https:\/\/www.darknet.org.uk\/2010\/09\/wifite-mass-wifi-wepwpa-key-cracking-tool\/\">wifite \u2013 Mass Wifi WEP \/ WPA Key Cracking Tool<\/a><br \/>\n&#8211; <a href=\"https:\/\/www.darknet.org.uk\/2007\/10\/aircrack-ng-wep-and-wpa-psk-key-cracking-program\/\">aircrack-ng \u2013 WEP and WPA-PSK Key Cracking Program<\/a><br \/>\n&#8211; <a href=\"https:\/\/www.darknet.org.uk\/2017\/09\/reaver-download-hack-wps-pin-wifi-networks\/\">Reaver Download \u2013 Hack WPS Pin WiFi Networks<\/a><\/p>\n<h4>coWPAtty download<\/h4>\n<p>You can download coWPAtty here:<\/p>\n<p><a href=\"https:\/\/sourceforge.net\/projects\/cowpatty\/files\/cowpatty\/cowpatty-2.0\/cowpatty-2.0.tgz\/download\">cowpatty-2.0.tgz<\/a><\/p>\n<p>Or read more <a href=\"https:\/\/sourceforge.net\/projects\/cowpatty\/\">here<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>coWPAtty is a C-based tool for running a brute-force dictionary attack against WPA-PSK and audit pre-shared WPA keys.
