How to hack a wpa2 psk wifi username and password


Password cracking for WiFi networks is one of the hacking activities that most interest beginner researchers, cybersecurity experts and sporadic users alike and, although it is possible to find information about it online, sometimes this is unclear & may not be aimed at the right audience.

That is why the experts of the cybersecurity course of the International Institute of Cyber Security (IICS) how khổng lồ complete these tasks relatively easily and in just a few steps. To vày this, we will use the utility known as coWPAtty, which simplifies and accelerates conventional dictionary attacks.

Before continuing, we remind you as usual that this article was prepared for informational purposes only & should not be taken as a gọi to action. IICS is not responsible for the misuse that may occur to lớn the information contained herein.

Step 1: Find coWPAtty

The utility is included by mặc định in the Kali Linux software package, although it is not in the /pentest/wireless directory. According to lớn the experts of the cybersecurity course, the application resides in the /usr/local/bin folder, which we will mở cửa below.

Since the utility is in the /usr/local/bin directory, it can be launched from any thư mục on Kali Linux.

Step 2: Use the coWPAtty help screen

For a brief description of the available options, the cybersecurity course experts recommend only typing the following command:


Then, Kali Linux will display a small help screen. Remember that coWPAtty requires some data khổng lồ work properly:

Word listFile with password hashingAccess point SSID to hack

Step 3: Switch the wireless adapter khổng lồ monitor mode

Like other hacking tools, coWPAtty requires changing the WiFi adapter khổng lồ monitor mode lớn get the password, mention the experts of the cybersecurity course.

Let’s run the following code:


Step 4: Create a tệp tin to intercept

Next, we need to lớn create a file to store the password intercepted during the 4-way handshake. To vị this, we will use the following code:

The above command will dump the selected access point (00:25:9C:97:4F:48), the specified channel (-c 9) và save the hash in a file called cowcrack, say the experts of the cybersecurity course.

Step 5: Handshake Interception

Now we just have khổng lồ wait for someone khổng lồ connect to lớn the compromised access point, which will allow us khổng lồ intercept the hashing. Cybersecurity course experts recommend using Airodump-ng lớn receive a notification when someone connects to lớn the target network.

Step 6: Run the utility

After getting the password with hashing, we can use coWPAtty along with our word danh mục to get the decrypted key.

Let’s run the following code:


The screenshot above shows how coWPAtty generates a hash for each word in our menu with the SSID and compares it khổng lồ the intercepted hash. Once the hash matches, the utility will display the access point password on the screen.

Step 7: Create your own hash

Typically, coWPAtty uses a menu of words provided by the user and calculates the hash of each based on the specified SSID, although this task consumes a large amount of processor resources, mention the experts of the cybersecurity course.

Luckily, now the utility has support for working with a ready-to-use hash file, which makes WPA2-PSK password cracking more efficient by more than 1000%. These files are generated using 172,000 dictionary files và 1,000 of the most popular SSIDs. Remember that if your SSID is not included in this list, the feature will not help us. In this case, we must generate our own hash các mục from the SSID of the access point used.

Let’s use the following code:


Step 8: Using your own hash

After generating a các mục of hashes for a specific SSID, we can start cracking the password by running the following command:

Although not the only utility of its kind, coWPAtty is one of the best options for WiFi password cracking as it is easy lớn use & does not require advanced hacking knowledge.
