How To Hack Wpa Wifi Passwords

How To Hack Wpa Wifi Passwords – Pyrit is one of the most powerful WPA/WPA2 cracking tools in the hacker’s arsenal, with the ability to measure a computer’s CPU speed, encrypt files for possible handshaking, and even disable GPU password cracking features. To show how fast it can hack WPA/WPA2 passwords, we use it to play a CTF hacking Wi-Fi game that anyone can do for under $10.

Wi-Fi is convenient but comes with inherent security issues that make it riskier to use than wired options. This is because anyone can access a WPA-encrypted Wi-Fi network if they know the password, giving attackers direct access to other devices on the network and to the internet in general. Choosing Wi-Fi passwords that are difficult to guess is important, because with a good password list and a program like Pyrit, a large list of passwords can be searched in minutes.

Although we don’t use GPU cracking today, Pyrit can use a suitable GPU to crack passwords faster. It depends on your computer hardware, and therefore the installation process will depend on the type of GPU you have and whether you choose to use OpenCL or CUDA. When it comes to GPU acceleration, Pyrit is one of the fastest WPA password cracking tools out there.

You might be lucky that your computer’s GPU is Pyrit compatible, but getting the GPU to run faster is a fun task that I leave to you with confidence. You can always try it by following Pyrit’s guide on GitHub for instructions, but I couldn’t get it to work properly on all the computers I tried it on, as of this writing.

Pyrit has many tools for hackers and pentesters besides cracking passwords, and today we’re going to use some of these tools to help us play the capture-the-flag Wi-Fi hacking game. A useful tool is the strip command, which strips a long capture file to include only relevant packets. Then there is a verification option that allows Pyrit to verify the results through calculations.

Pyrit has a feature that includes a list of passwords in a large database. To avoid duplicates, the import_unique_passwords command can remove passwords that appear repeatedly in the same file we are trying to import. After entering the password into the database, we can start cracking it using the attack_batch option.

In Kali Linux we can see the device description by clicking on the pyrite icon in the window.

Common Wifi Protocol Wpa2 Has Been Hacked

Without adding characters to the Pyrit file, the most common attack we can run with Pyrit is the attack_passthrough option, summarized by the manual definition.

Although we will improve this by uploading some words into the database first, the general form of passwords with Pyrit is easy to use.

To follow along, you need at least a Kali-compatible network adapter, a Wi-Fi network whose password you know, a device such as a smartphone that connects to the network to work with handshaking, and a computer running Kali Linux.

If you want to try our example easily, you can use an ultra-cheap ESP8266 microcontroller programmed in an Arduino to create a Wi-Fi network to hack and generate hands simultaneously. For those who want to practice with MCU, my friends and I have written a CTF hacking Wi-Fi game called ChickenManGame, which is the most popular (and only) CTF hacking Wi-Fi game based on ESP8266 in the world.

Cracking Your Wpa2 Wi Fi Password Just Became Easier

To play games, I recommend using a NodeMCU or D1 Mini microcontroller, both of which are based on the ESP8266 and cost between $2 and $5 per board. Load the ChickenManGame sketch on the Arduino, install the necessary libraries and copy the code to the ESP8266 according to the instructions in the GitHub repository. Once you’ve coded each microcontroller, connect a red, green, and blue LED to each one as shown in the instructions on GitHub.

Finally, connect each device to a Micro-USB power source and then connect a jumper cable from pin D7 to ground where it belongs. An ESP8266 without pin D7 connected to ground creates a Wi-Fi network called “Chicken Easy” with a number at the end. The second device with pin D7 connected to ground will connect to the Wi-Fi network created by the first device, creating a WPA phone that you can easily capture and hold.

In our game today, we will try to connect to a Wi-Fi access point encrypted with a WPA/WPA2 password that we do not know. We’ll do this in a few steps, using airodump-ng to capture the handshake and Pyrit to crack the password.

To install Pyrit on a Kali system, type apt install pyrit in the window. Pyrit is installed by default in the full Kali installation, but for the simplified version you may need to install it manually.

When the installation is complete, type pyrit -h to print the help menu and confirm that it is installed on our system.

For our attack, we will use the attack_batch option, and we need two details for the command to run.

First, we need to install the capture file where our WPA/WPA2 handshakes are stored. Next we need to add a list of passwords to Pyrit, we can do it with the import_unique_passwords command and the -i flag to show the list of passwords we want to add. We will use the WPA password list from the SecLists GitHub repository. Finally, we’ll use the -o flag to store the password in a file.

Before we can perform the attack, however, we need to capture the list of handshakes and passwords, so let’s capture those first.

For our password list, we downloaded the best WPA cracking dictionary available on GitHub’s SecList repository. To download it to our desktop, press this command in the window.

When we’re done, we should have a password list of the best 4,800 passwords available to start with downloaded to our desktop. To see how fast we can cut it, we need to compare our system with Pyrit. To do so, place a pyrite benchmark in the window and wait for it to complete.

Here we can see that my old Lenovo can test about 1,157.3 PMK per second, which means it takes about 4.1 seconds to test each password in . Compare that to the new Macbook Pro at 4,226 PMK per second and you’ll see the power of the CPU when it comes to breaking down.

Add our passwords to the database using the import_passwords command, adding -i and the path to the list of passwords we want to add. Type this command in your window, change the password list to match the one you saved.

To get started, we need to know one thing about our Wi-Fi network. First, let’s put our card in wireless mode so we can listen to files manually.

First, open a new window and type ifconfig to find the name of your wireless network adapter. If you are using an external USB adapter compatible with Kali, it will be called wlan1.

Next, we will put our card in wireless monitor mode with the airmon-ng start wlan1 command. Airmon-ng is installed in Kali by default. When we run ifconfig again, our card will now be called “wlan1mon.” Now let’s shake hands.

First, we’ll run a scan to see which channels our mobile network is on. To do so, run airodump-ng wlan1mon. Also, you must have airodump-ng.

We can see our target network on channel 3. Now that we know this, we can capture the handshake with the capture command airodump-ng wlan1mon -c 3 -w.

When you receive a handshake, you can confirm with Pyrite. After copying the location of your capture file, run the command pyrit -r pathtocapturefile analysis to verify your capture.

Now that we’ve captured the handshake and added the password to the database, we can run our attack_batch command we created earlier. Run the command pyrit -r pathtocapturefile -o savedpass attack_batch to test the handle we captured.

Good luck! If you play our CTF hack Wi-Fi game, you can enter the Wi-Fi access point, navigate to 192.168.4.1 and click on your team’s color to claim a share of the game for your company.

If you haven’t played our game, you’ve just cracked a WPA/WPA2 network password, if it’s listed. Otherwise, you might need a very large list of passwords, which means you’re trying to be malicious.

While we haven’t gone into everything Pyrite has to do today, there’s still a lot we haven’t covered. Of course, even though Pyrit is one of the strongest attacks out there, the strongest password will always win the attack. Pyrit can create dictionaries and attacks that are actually based on what your system can handle, so it’s safe
