As part of my series on hacking Wi-Fi, I want to demonstrate another excellent piece of hacking software for cracking WPA2-PSK passwords, coWPAtty. In this tutorial, we’ll use the piece of software developed by wireless security researcher Joshua Wright (often stylized as coWPAtty). This app simplifies and speeds up the dictionary/hybrid attack against WPA2 passwords. It is easier than you think, so let’s get to it!
Step 1: Find the Cowpatty
Major password-cracking tool, Hashcat, found a simpler way to hack your WPA/WPA2 enabled Wi-Fi networks. Here's what businesses need to know. 5 tips for keeping your data safe while traveling. So make sure you build out specific wordlists dependent on the WiFi AP you want to crack. There are many other tools that you can use for the capture of the handshake and the cracking of the handshake. I prefer wifite as its easy to use and great for beginners and aircrack-ng has easy to remember syntax for piping a handshake to a wordlist. Aircrack is one of the most popular wireless passwords cracking tools to help you crack 802.11a/b/g WEP and WPAs. The system uses the best algorithms to recover the password of any wireless network by capturing packets. Once it gathers enough packets, the software tries to recover the password. It took about 5 hours to crack 19 characters WPA2 password (vishnuvalentino.com) from my Kali virtualBox, but it depend with our hardware and wireless card. WPA and WPA2 security implemented without using the Wi-Fi Protected Setup (WPS) feature are unaffected.
Cowpatty is one of the hundreds of pieces of software that are included in the BackTrack [Download] and Kali [Download] OS’s. If you are using a different Distro, you can download and install coWPAtty Here. For this demo, I will be using BackTrack. For some reason in BackTrack, it was not placed in the /pentest/wireless directory, but instead was left in the /usr/local/bin directory, so let’s navigate there.
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. Take a note that cowpatty requires all of the following:
- a word list
- a file where the password hash has been captured
- the SSID of the target AP
Step 3: Find the AP
Just as in cracking with aircrack-ng, we need to put the wireless adapter into monitor mode.
airmon-ng start wlan0
Now, look at the available APs using the monitor interface and airodump:
airodump-ng mon0
leave this screen by hitting CTRL+C
Step 4: Start a Capture File
Next, we need to start a capture file where the hashed password will be stored when we capture the 4-way handshake.
airodump-ng –bssid 00:25:9C:97:4F:48 -c 9 -w cowcrack mon0
This will start a dump on the selected AP (00:25:9C:97:4F:48), on the selected channel (-c 9) and save the the hash in a file named cowcrack.
Step 5: Capture the Handshake
Now when someone connects to the AP, we’ll capture the hash and airdump-ng will show us it has been captured in the upper right-hand corner. Some people just wait for a computer to connect. Other people send DEAUTH packets to kick them off the wifi, and then they automatically connect again, at which time you will capture the handshake. I may cover this tomorrow or the next day.
Step 6: Run the Cowpatty
Now that we have the hash of the password, we can use it with cowpatty and our wordlist to crack the hash.
cowpatty -f /pentest/passwords/wordlists/darkc0de.lst -r /root/cowcrack-01.cap -s Mandela2
As you can see in the screenshot above, cowpatty is generating a hash of every word on our wordlist with the SSID as a seed and comparing it to the captured hash. When the hashes match, it dsplays the password of the AP.
Step 7: Make Your Own Hash
What Is A Wpa2 Password For Mac
Although running cowpatty can be rather simple, it can also be very slow. The password hash is hashed with SHA1 with a seed of the SSID. This means that the same password on different SSIDs will generate different hashes. This prevents us from simply using a rainbow table against all APs. Cowpatty must take the password list you provide and compute the hash with the SSID for each word. This is very CPU intensive and slow.
Cowpatty now supports using a pre-computed hash file rather than a plain-text word file, making the cracking of the WPA2-PSK password 1000x faster! Pre-computed hash files are available from the Church of WiFi [ Link ], and these pre-computed hash files are generated using 172,000 dictionary file and the 1,000 most popular SSIDs. As useful as this is, if your SSID is not in that 1,000, the hash list really doesn’t help us. Plus rainbow tables are Gargantuan to download!
In that case, we need to generate our own hashes for our target SSID. We can do this by using an application called genpmk. We can generate our hash file for the “darkcode” wordlist for the SSID “Mandela2” by typing:
genpmk -f /pentest/passwords/wordlists/darkc0de.lst -d hashes -s Mandela2
Step 8: Using Our Hash
Once we have generated our hashes for the particular SSIDs, we can then crack the password with cowpatty by typing:
cowpatty -d hashfile -r dumpfile -s ssid

Lately, a new pattern is discovered in WPA/WPA2 protocols to crack the WPA key passphrase which uses an alternative key to that of 4-way handshake. This new attack uses an identifier key named PMKID in place of MIC which is supplied in the first packet of 4-way handshake. So, this new technique made the WPA cracking more effective and easier than ever before.
The 4-way handshake is in itself dependent on it's 4 frames to compute the hashed key. So, in order to crack the WPA/WPA2 key, we require a complete WPA handshake to crack the password. But with this vulnerability discovered by Jen Steube we are no longer dependent on deauthentication frames, clients etc. Now, we are better able to crack the key by initiating an authentication process with the access point. Let's see.
Here's how the Pairwise Master Key ID (PMKID) is computed. Basically, it's the concatenation of PMK key, PMK secret key, MAC of AP and MAC of STA.
While in this case, the computing process is rather simple. The former method of cracking requires a valid handshake, comprised of at least the first two EAPOL messages to compute the MIC code which then has to be matched at second or fourth frame (relatively different concepts). Here's the python version of the previous method:
Prerequisities
Let's make it up. You would need a Kali Machine and wireless Card that supports packet injection and monitor mode. Tested with Alpha from TP-Link, worked fine. A vulnerable WPA2 router. Here's a picture of EAPOL from a vulnerable router:
STEP 1
Setup environment.
Put your wireless card in monitor mode:
Next thing is, we need some tools from github. The list is:
Change Wifi Password In Window 10
- hashcat >= 4.2.0
- hcxtools
- hcxdumptool
Installation:
Update the environment first and install the dependencies:
If you are on Kali, hastcat would already be in repository packages. You would need to first uninstall it and then install the latest version from github:
Then make sure, you have the version >= 4.2.0 by using the command:
Now, clone hcxtools from github and compile the binaries:
Then at last, clone hcxdumptool and compile the binaries:
STEP 2
Get the PMKID
This step is about collecting the PMKID. Compile a list of your targets. Scan your area with airodump:
Now, create a list of your targets by writing the MAC address of target to a file:
Then start hcxdumptool:
This will try to make the AP transmit the first EAPOL frame which then will be used to acquire the PMKID from the RSN element layer. Just keep it running until you get the message that PMKID is captured. Here's what it would look like:
STEP 3
Get the PMKID hash
As of now, we have the captured file. Now, we need to extract the PMKID hash from the capturefile.cap. Use hcxpcaptool for this:

Now, check the added hashes:

STEP 4
Crack the Code
We have the PMKID hash. All we need now is to crack it down using hashcat. Now, run the hashcat with the following syntax:
This would start cracking the password. A successful attack would go like this:

Conclusion
How To Crack Wifi Wpa2 Password Using Windows 10 Password
WPA key passphrase can be cracked using PMKID which is located in the first packet of 4-way handshake. The first packet of 4-way handshake is basically sent by the WiFi or Access Point which contains some random keys to encrypt data and also contains the required PMKID key. A user just have to initiate a connection with the Access Point which in turn will sent the first EAPOL message to the client and the client just have to sniff that and start the cracking process.
