Crack WiFi password + Secure Your WiFi Against Hackers

You might be surprised how easy it is to hack a Wi-Fi or home network these days. For very little money, a hacker can use a variety of methods and find your network password in minutes. In addition, if you have a weak password, your Wi-Fi password can be easily cracked. In the following, we will show you how hackers can hack your WiFi password and what should be done to prevent this from happening.

Type of Wifi hacks

WiFi hacking has many reasons, the most important reasons are as follows:

•  Simple encryption is used for WiFi passwords.
• Carelessness in changing the default password of the router and not changing the password  of the Wi-Fi network
• Saving passwords on devices that may be accessible to others
•  Using keylogger software to record typed phrases on devices connected to the desired network

Cracking WiFi at Scale

Wireless networks use different encryption structures to exchange information. In general, the most common communication protocols of these networks are (WEP, WPA, WPA2, WPA3). The weakest of them is WEP and the strongest is WPA3.

Please note, this training is provided only to check and test the security level of your personal Wi-Fi network, so that you know how you will be hacked if you do not comply with the stated items. The main creators of this program have provided it for penetration testing and network vulnerability.

Since most of today's modems use the WPA structure for encryption by default, in this tutorial, we will not discuss how to hack this type of encryption, so as not to tempt you to hack the neighbor's Wi-Fi.

But in order to better understand the effect of the encryption algorithm in wireless networks, we have provided you with an example of hacking a Wi-Fi network based on WEP encryption, so that when configuring the modem, you'll be aware of the vulnerability of this algorithm and never use this protocol. 

But be careful, all Wi-Fi networks can be hacked in the same way with more time. So, in the continuation of this article, read the ways to prevent WiFi hacking.

⚠️ Note: This article is only an educational article that is presented to check and test the  penetration of your Wi-Fi network.

Aircrack-ng is the most famous program for checking and testing penetration into Wi-Fi networks. which has a number of graphic formats, we have used the WEBCrack graphic format here. To check and test penetration into a network using this program, follow the steps.

Here we have deliberately changed our encryption structure to WEP so that you can see operationally how weak this type of encryption is.

 

First step - Penetration test

First, select the WEP option to view the networks that are active with this encryption, and then select the desired network and click on the Test Injection option, then wait for the test to be checked until the penetration test is done.

 

 

Second step - start monitoring

When the confirmation of the possibility of penetration with the word OPN is displayed, we select the word Start Monitor to start sending packets to the network.

 

 

Third Step  - start authentication

Go to the authentication tab and select the Start authentication button to start the process of sending access packets.

 

Wait until the network information is displayed on the screen and the green tick appears at the bottom of the program.

 

Fourth step - start attacking the network

Now we have to start the necessary attacks to get the response log sample from the desired network so that we can crack the network password according to it. For this, we refer to the tab and click on the Start Attack option.

 

We wait until the state of at least one of the two attack methods turns into a green tick.

 

Fifth step - crack and hack WiFi password

Well, now it's time to crack and decrypt the password, just go to the crack tab and select the Start Crack button.

 

As you can see, due to the weak encryption structure of the WEP protocol, the desired Wi-Fi network password was hacked in less than a few minutes. But you should not worry, we will continue to discuss how to increase the security of the Wi-Fi network and deal with this type of attack.

How To Secure Your Home Wi-Fi Network

WiFi hacking is often related to small mistakes by users when connecting devices to the network or setting up the router. To avoid the worst of these mistakes, there are a few simple precautions you can take to avoid becoming a victim of WiFi hacking.

 

Where Is the Best Place to Set Up Your Router?

It may come as a surprise, but the truth is that the location of your modem at home is important to prevent your WiFi from being hacked! If you place the modem in the middle of your home or workplace, you have greatly reduced the possibility of access and reception of signals for hackers and they will not be able to access the packets being exchanged in the network. This has other benefits, such as stronger connectivity throughout the workplace or home.

How to Change Your WiFi Name and Password?

Each device has its Wi-Fi name and password. Also, the default password to the modem settings section is the same for most devices.

On the other hand, the default name on your modem refers to the type of your device, and by understanding this, hackers can easily hack your Wi-Fi and find out its default password.

Some people think that choosing WiFi names like Can't hack this is a creative way to prevent WiFi hacking. But this issue can encourage hackers more.

Try not to use your own name to change the name of your modem, because if the hacker is familiar, he can easily guess your Wi-Fi password by choosing numbers from your mobile number, date of birth, etc.

How to choose a secure password?

As we have mentioned earlier, another way to increase the security of Wifi networks is to change their password encryption protocol.

To do this, enter the configuration page of your router as before and refer to the Wi-Fi settings section again. Then, in the "Authentication Mode" section, you can also change the encryption algorithm of the selected password.

 

 

Try to choose a new password for your modem, a combination of uppercase and lowercase letters, numbers and even symbols and around 20 characters. Avoid using common names and numbers such as phone numbers and date of birth. Paying attention to these tips makes hacking your WiFi network impossible to a large extent.

From the point of view of hackers, networks with WPS enabled are the easiest model of networks to hack. With one command, a hacker can scan the local area for networks that support WPS and find a good target to hack. Also, if in a company all employees use the same password for Wi-Fi, this password must be changed the next day.

How do I change the IP address on a modem?

Changing the modem IP makes it more difficult for WiFi hackers, so it is better to do this to increase the security level of your device.

How to create an isolated guest wifi?

A devastating mistake made by many small businesses is that, when they offer Wi-Fi to customers, not restricting guest users to their own private Wi-Fi leads to faster Wi-Fi hacks. Creating separate networks for guest users means that each client can only communicate with the router and is not free to scan other devices on the network or try to connect to open ports.

Additionally, the router should not have any ports available that host management or configuration pages from the guest network, as these pages often contain information that a hacker could use to exploit the router.

Without isolating the network used by the client, anyone on the network can see and interact with every other connected device. This means that security cameras, DVR systems, the router itself, and NAS or file servers on the network can be directly accessible to hackers from the moment they join the network, making it much easier to find the weakest network link.

How to update your router's firmware?

If your router system has automatic updates, you don't need to do anything special; But in some cases you have to manually update your Wi-Fi device. The importance of this issue is because hardware problems can sometimes make it easier for hackers to penetrate Wi-Fi, and the good news is that these bugs are fixed in system updates.

Download it according to the instructions in the support section of your device.Be careful when doing this, as it may damage your device.

Restrict Network Traffic by MAC Address

Each device's unique serial number is known as the Media Access Control Address. For more security, it is better to enable this feature in your modem so that access to unauthorized people is blocked, even if they have a password.

Find WiFi password in Windows

The process of finding the WiFi password with the help of auxiliary programs such as WiFi password revealer is not a difficult task. In the Windows operating system, just install this program and run it and easily view the Wi-Fi passwords stored on your computer or laptop.

 

 

How to View the Wifi Password on Android?

To find the password of WIFI networks in Android devices and mobile phones, you can also follow these steps:

1. Go to the settings of the mobile phone
2.  then go to the Network & internet or WIFI section.
3. tap on the connected network

By default, the QR code for connecting to the relevant network should be displayed for you. If you do not see the QR code, select the share option so that the QR code will be displayed to you. Now you can scan the QR code with another device so that the password of the Wi-Fi network you want will be displayed.

How to tell if someone hacked your router?

If the speed of your Wi-Fi has decreased or the volume of your Internet package is running out quickly, it may be that your Wi-Fi has been hacked, or that your traffic is being used by phone hacking tools or other malware. ! But don't worry, by observing the stated tips, your Wi-Fi security will reach the maximum possible level.
