How to Hack Wi-Fi: Cracking WPA2-PSK Passwords with Cowpatty. How to Hack Wi-Fi: Cracking WPA2-PSK Passwords with Cowpatty Welcome, my hacker novitiates!
As part of my series on hacking Wi-Fi, I want to demonstrate another excellent piece of hacking software for cracking WPA2-PSK passwords. In my last post, we cracked WPA2 using aircrack-ng. In this tutorial, we'll use a piece of software developed by wireless security researcher Joshua Wright called cowpatty (often stylized as coWPAtty). This app simplifies and speeds up the dictionary/hybrid attack against WPA2 passwords, so let's get to it! Step 1: Find Cowpatty Cowpatty is one of the hundreds of pieces of software that are included in the BackTrack suite of software. Cd /usr/local/bin Because cowpatty is in the /usr/local/bin directory and this directory should be in your PATH, we should be able to run it from any directory in BackTrack. Step 2: Find the Cowpatty Help Screen To get a brief rundown of the cowpatty options, simply type: cowpatty BackTrack will provide you a brief help screen. See Also. Cracking WPA/WPA2 Encryption.
About a month ago, to my embarrassment, I learned that my Wi-Fi password was so weak that even my 10 year old neighbour could crack it… No, not really.

We’re going to start with a little introduction to Kali Linux, because that is the OS I prefer, is the easiest for this task and comes with all the tools we need. In this tutorial, I’m going to hack into a Wi-Fi hotspot that I just set up, named – Anonymus.
Here, we only need (wlan0) which is our Wi-Fi card, so we can disable the others by doing “ifconfig <name of the interface> down”. Now, we type “airmon-ng start wlan0” Then, put in, “airodump-ng mon0”. Annnnd… Voila! Researchers publish open-source tool for hacking WiFi Protected Setup. On December 27, the Department of Homeland Security's Computer Emergency Readiness Team issued a warning about a vulnerability in wireless routers that use WiFi Protected Setup (WPS) to allow new devices to be connected to them. Within a day of the discovery, researchers at a Maryland-based computer security firm developed a tool that exploits that vulnerability, and has made a version available as open source. WiFi Protected Setup, a standard created by the WiFi Alliance, is designed specifically for home and small business users of wireless networking to easily configure devices without having to enter a long password.
Offered as an optional feature on WiFi routers from a number of manufacturers, it automates the setup of the WiFi Protected Access 2 (WPA2) authentication between the router and a wireless device. That wouldn't be as much of a problem for security if wireless access points locked out devices after repeated bad PIN entries. How to Crack a Wi-Fi Network's WPA Password with Reaver.

Wireshark, a network analysis tool formerly known as Ethereal, captures packets in real time and display them in human-readable format.
Wireshark includes filters, color-coding and other features that let you dig deep into network traffic and inspect individual packets. This tutorial will get you up to speed with the basics of capturing packets, filtering them, and inspecting them. You can use Wireshark to inspect a suspicious program’s network traffic, analyze the traffic flow on your network, or troubleshoot network problems. Getting Wireshark You can download Wireshark for Windows or Mac OS X from its official website.
Just a quick warning: Many organizations don’t allow Wireshark and similar tools on their networks. Capturing Packets After downloading and installing Wireshark, you can launch it and click the name of an interface under Interface List to start capturing packets on that interface. Color Coding You’ll probably see packets highlighted in green, blue, and black. How to Crack a Wi-Fi Network's WEP Password with BackTrack. Aircrack-ng.
