How to hack wlan network system

So, I am telling you the method to hack a secured WiFi network, crack its password and enjoy free internet using it. Before moving directly to the methods to hack WiFi networks lets first see what type of security and authentication methods are implemented in WiFi networks. If somebody is already connected to the network, you can check in his network properties to see what encryption-type is being using by the targeted WiFi network. But if you want to know encryption-type of WiFi network which is not connected to any device in your reach, you need Ubuntu operating system to do this.

In Ubuntu, you can use nmcli command in terminal which is command-line client for NetworkManager. It will show you security types of nearby Wi-Fi access points.

Enter the following command in terminal:. Using the above methods, you should have known the encryption-type of targeted WiFi network which you want to hack. My methods require KALI Linux which is especially designed Linux distrbution for penetration testing and ethical hacking. You can download it for free from its official site. You will also need Aircrack-ng which is a security suite to assess WiFi network security. It focuses on different area of WiFi security: monitoring, attacking, testing and cracking.

Another important requirement is to check if your wireless card is compatible with Aircrack-ng or not. When a user authenticates through the Access Point the user and the Access Point have to go through a 4-way Handshake in order to complete the authentication process.

In Wi-Fi hacking, we capture the 4-way handshake packet and look for the encrypted key in those packets. After getting the encrypted key we try a specific wordlist in order to crack the encrypted password. Though there are many other ways as well to crack a wifi password the one with wordlist is the easiest to use and is widely used by the attackers. Hacking Wi-Fi 1. List all the available network Interfaces. The airmon-ng tool is used to work with network interfaces.

Enter the following command to get the list of all the available network interfaces. Monitor the desired network interface. The next step is to monitor the wireless network interface, so that we may see all the traffic that passes through the interface. To do so we will use airodump-ng tool. As wireless networks communicate through radio waves, a hacker can easily sniff the network from a nearby location. Most attackers use network sniffing to find the SSID and hack a wireless network.

When our wireless cards are converted in sniffing modes, they are called monitor mode. Kismet is a powerful tool for wireless sniffing that is found in Kali distribution. First of all, open a terminal and type kismet. Start the Kismet Server and click Yes, as shown in the following screenshot. Now, Kismet will start to capture data. NetStumbler is another tool for wireless hacking that is primarily meant for Windows systems.

It is quite easy to use NetStumbler on your system. You just have to click the Scanning button and wait for the result, as shown in the following screenshot. It is important to note that your card should support monitoring mode, otherwise you will fail to monitor.

Here are some of the ways by which the wifi is a hack:. In this way, the wi-fi can easily be hacked using the command prompt. However, In advance case, unlike this info; The wi-fi network needs to be highly protected with a security key, if not, using just a Wi-Fi eavesdropper, hackers can grab the secure information hidden within your laptop or PC. That brings your businesses with a reputation in a loss. So always try to change a password within a week or if any irregularities like slowdown of wi-fi, auto camera open, mouse automatically moving, then be sure that you are in danger, so be protected either by turning off instantly or change the wifi username and password or even make hidden.
