How to Install Pyrit in Kali Linux for Faster Password Cracking
Pyrit is a tool that allows you to create massive databases of pre-computed WPA/WPA2-PSK authentication phase in a space-time tradeoff. By using the computational power of multi-core CPUs and other platforms such as Nvidia-CUDA and OpenCL, Pyrit is one of the most powerful attacks against one of the most used security protocols in the world.
In this article, we will show you how to install Pyrit in Kali Linux, a popular distribution for ethical hacking and penetration testing. We will also show you how to use Pyrit to crack the password of a wireless network using a capture file.
Prerequisites
Before we start, you will need the following:
A computer with Kali Linux installed and updated.
A wireless adapter that supports monitor mode and packet injection.
A capture file of a WPA/WPA2 handshake or PMKID.
An internet connection to download Pyrit and its dependencies.
Step 1: Update System and Install Dependencies
The first step is to update your system and install the required dependencies for Pyrit. Open a terminal and run the following commands:
sudo apt update -y
sudo apt install git python2-dev libssl-dev libpcap-dev -y
This will update your system's package list and install Git, Python 2 development files, OpenSSL development files, and libpcap development files.
Step 2: Clone Pyrit from GitHub
The next step is to clone Pyrit from its GitHub repository. Run the following command in the terminal:
git clone https://github.com/JPaulMora/Pyrit.git --depth=1
This will clone the latest version of Pyrit into a folder named Pyrit in your current directory. You can also specify a different folder name if you want.
Step 3: Compile and Install Pyrit
The third step is to compile and install Pyrit on your system. To do this, change your directory to the Pyrit folder and run the following commands:
cd Pyrit
sed -i "s/COMPILE_AESNI/COMPILE_AESNIX/" cpyrit/_cpyrit_cpu.c
python2 setup.py clean
python2 setup.py build
sudo python2 setup.py install
The first command changes your directory to the Pyrit folder. The second command edits a file named _cpyrit_cpu.c and replaces COMPILE_AESNI with COMPILE_AESNIX. This is necessary to avoid an error when running Pyrit later. The third command cleans any previous build files. The fourth command builds Pyrit using Python 2. The fifth command installs Pyrit on your system using sudo privileges.
Step 4: Test Pyrit
The fourth step is to test if Pyrit is working properly on your system. To do this, run the following command in the terminal:
pyrit -h
This will display the help message of Pyrit, showing its usage and options. If you see something like this, then Pyrit is installed successfully:
Pyrit 0.5.1 (C) 2008-2011 Lukas Lueg - 2015 John Mora
https://github.com/JPaulMora/Pyrit
usage: pyrit [options] command
Options:
-h, --help show this help message and exit
-u URL, --url=URL URL of storage-system to use; default: 'file://'
-r FILENAME packet capture file in pcap-format
-o FILENAME output file for passwords or hashes
-i FILENAME input file for passwords or hashes
-e ESSID ESSID (name) of the network
-b BSSID BSSID
Step 5: Use Pyrit to Crack a Wireless Password
The fifth step is to use Pyrit to crack the password of a wireless network using a capture file. To do this, you will need a capture file that contains a WPA/WPA2 handshake or a PMKID. You can obtain such a file by using tools like airodump-ng, hcxdumptool, or hashcat.
Once you have a capture file, you can use Pyrit to analyze it and see the available networks and handshakes. Run the following command in the terminal, replacing capture_file with the name of your capture file:
pyrit -r capture_file analyze
This will display something like this:
Parsed 42 packets (42 802.11-packets), got 1 AP(s)
#1: AccessPoint 00:14:6c:7e:40:80 ('teddybear'):
#1: Station 00:0f:b5:fd:fb:c2, 1 handshake(s):
#1: HMAC_SHA1_AES, good, spread 1
This shows that the capture file contains one access point with the ESSID teddybear and the BSSID 00:14:6c:7e:40:80, and one station with the MAC address 00:0f:b5:fd:fb:c2, and one handshake of type HMAC_SHA1_AES.
To crack the password of this network, you will need to import some passwords into Pyrit's database. You can use any wordlist or dictionary file that contains possible passwords. For example, you can use the rockyou.txt wordlist that comes with Kali Linux. To import the passwords from a file into Pyrit's database, run the following command in the terminal, replacing password_file with the name of your password file:
pyrit -i password_file import_passwords
This will import the passwords from the file into Pyrit's database and display something like this:
Importing from password_file...
Processed all lines; 14344391 passwords imported.
This shows that Pyrit has imported 14344391 passwords from the file.
The next step is to compute the PMKs (Pairwise Master Keys) for each password and store them in Pyrit's database. This is the most time-consuming step, as it requires a lot of CPU and GPU power. To compute the PMKs for all passwords in Pyrit's database, run the following command in the terminal:
pyrit batch
This will start computing the PMKs for each password and display something like this:
Working on ESSID 'teddybear'
Processed all workunits for ESSID 'teddybear'; 14344391 PMKs calculated.
This shows that Pyrit has computed 14344391 PMKs for the ESSID teddybear.
The final step is to use Pyrit to attack the capture file and try to find the password that matches the handshake. To do this, run the following command in the terminal, replacing capture_file with the name of your capture file:
pyrit -r capture_file attack_db
This will start attacking the capture file using the PMKs stored in Pyrit's database and display something like this:
Attacking handshake with station 00:0f:b5:fd:fb:c2...
Tried 14344391 PMKs so far; 1000 PMKs per second.
The password is '12345678'.
This shows that Pyrit has found the password for the network teddybear. It is 12345678.
Conclusion
In this article, we have shown you how to install Pyrit in Kali Linux, a powerful tool for cracking WPA/WPA2 passwords using a space-time tradeoff. We have also shown you how to use Pyrit to analyze a capture file, import passwords, compute PMKs, and attack a handshake. Pyrit can leverage the computational power of multi-core CPUs and other platforms such as Nvidia-CUDA and OpenCL to speed up the cracking process. Pyrit is a useful tool for ethical hackers and penetration testers who want to test the security of wireless networks.
