Improve this question. M'vy has succinctly captured a deep truth of password cracking here. Using iwconfig again, will now show that your interface is in Monitor Mode and has also been renamed from wlan0 to wlan0mon. Capture and Verify 4-way handshake: The communication that happens when a wireless device authenticates to a WPA-enabled access point is called a 4-way handshake.

Below is an example of an incomplete capture Message 1 of 4 is missing : Below is an example of a complete capture all 4 Messages are present :. Bill McCauley Aug 18, Jason Gillam May 16, Professionally Evil: This is NOT the Wireless Access Point You are Looking For I was recently conducting a wireless penetration test and was somewhat disappointed but happy for our client to find that they had a pretty well Jason Wood May 11, To capture a handshake, we'll need to listen in on one device connecting to our target Wi-Fi network.

First, let's put our card into wireless monitor mode so that we can listen in on handshake files. First, open a terminal window and type ifconfig to locate the name of your wireless network adapter.

If you're using an external USB adapter that's compatible with Kali, it will probably be named something like wlan1. Next, we'll put our card into wireless monitor mode with the command airmon-ng start wlan1. Airmon-ng is installed on Kali by default.

When we run ifconfig again, our card should now be called "wlan1mon. First, we'll run a scan to find what channel our target network is on. To do so, run airodump-ng wlan1mon. Again, you should already have airodump-ng. We can see our target network is on channel 3. Now that we know this, we can capture a handshake with the command airodump-ng wlan1mon -c 3 -w capture.

When you've captured a handshake, you can confirm it with Pyrit. After copying the location of your capture file, run the command pyrit -r pathtocapturefile analyze to confirm you have a valid capture. If it wasn't, you might need a more extensive password list, even to try brute-forcing it.

So IMHO, the dictionary attack in an ideal situation is the fastest. Of course it you won't have an ideal situation in real life. Because, as you said, getting the dictionary words to the GPU is a bottleneck, you can use rules to to have the otherwise [mostly] idle GPU create some variants of each dictionary word.

Obviously, not all rules are going to be equally effective, and picking the set that would give you the best result is both an art mixed with some luck.

They are useful, as not all passwords are based on a [mangled] dictionary word. Dictionaries can have numbers as words. The trickiest part is getting the good mask s. PACK has a nice mask generator, but that is based on what you've already cracked by other means, including other mask attacks. However, to be effective, PACK requires your cracked passwords be representative of all the passwords, so feeding it passwords cracked solely by masks isn't likely to give good results.

Or if you know the person who created the password doesn't believe 0 is a number, that can be used in a custom character set.
