This is very CPU intensive and slow.Ĭowpatty 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, and these pre-computed hash files are generated using 172,000 dictionary file and the 1,000 most popular SSIDs. Cowpatty must take the password list you provide and compute the hash with the SSID for each word. This prevents us from simply using a rainbow table against all APs. This means that the same password on different SSIDs will generate different hashes. The password hash is hashed with SHA1 with a seed of the SSID. When the hashes match, it dsplays the password of the AP.Īlthough running cowpatty can be rather simple, it can also be very slow. Now that we have the hash of the password, we can use it with cowpatty and our wordlist to crack the hash.Ĭowpatty -f /pentest/passwords/wordlists/darkc0de.lst -r /root/cowcrack-01.cap -s Mandela2Īs 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. 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. 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. Next, we need to start a capture file where the hashed password will be stored when we capture the 4-way handshake.Īirodump-ng -bssid 00:25:9C:97:4F:48 -c 9 -w cowpatty mon0 Just as in cracking with aircrack-ng, we need to put the wireless adapter into monitor mode. Step 3Place the Wireless Adapter in Monitor Mode Take a note that cowpatty requires all of the following.Ī file where the password hash has been captured
To get a brief rundown of the cowpatty options, simply type:īackTrack will provide you a brief help screen.
For some reason, it was not placed in the /pentest/wireless directory, but instead was left in the /usr/local/bin directory, so let's navigate there.īecause 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.
CRACK WPA2 KALI RAINBOW TABLES SOFTWARE
This app simplifies and speeds up the dictionary/hybrid attack against WPA2 passwords, so let's get to it!Ĭowpatty is one of the hundreds of pieces of software that are included in the BackTrack suite of software. In this tutorial, we'll use a piece of software developed by wireless security researcher Joshua Wright called cowpatty (often stylized as coWPAtty).
CRACK WPA2 KALI RAINBOW TABLES CRACKED
In my last post, we cracked WPA2 using aircrack-ng. As part of my series on hacking Wi-Fi, I want to demonstrate another excellent piece of hacking software for cracking WPA2-PSK passwords.
