In this hi-tech life, we always need a working internet connection to manage both our professional and personal life. The most comfortable way to access internet everywhere anytime is by buying mobile data recharges but they are very expensive. Another good way to connect to free WiFi if it’s luckily available at your workplace, college or home. But everyone is not that lucky.

Everybody might have many fast WiFi hotspots available in their smartphone’s range, but they don’t have access to those WiFi connections because they are password protected and you don’t have access to them so, you can’t use those WiFi hotspot to access internet in your smartphone or laptop. But, what if you can hack a WiFi?

CloudCracker is an online password cracking tool to crack WPA keys of Wireless network. This tool can also be used to crack various other kind of password hashes. You only need to upload the handshake file and enter the network name to start the attack. With 3000 million words long dictionary, this tool is most likely to crack the password. If you are looking to learn Wi-Fi password hacking, this newly discovered flaw in WPA/WPA2 protocol will surely help you out. Wifi password hacking has become popular as people are always in search of the free internet. But due to the advancement of technology, hacking wifi, and cracking passwords have become a difficult task to do.

NetStumbler Best PC WiFi password cracker software NetStumbler, basically known as Network Stumbler, is a Windows tool that detects 802.11b, 802.11a, 802.11g wireless LANs.
When the Crack or WPA key is discovered it's very simple to use and take advantage of it.3. As the Software functions on WPS enabled routers, it doesn't give you a headaches to find it yourself. It detects it automatically.4.

Yes, I am not joking. What if you can hack any WiFi available in your range and crack it’s password to access free and unlimited internet? IMO, if you can learn a way to hack a WiFi network then you can access free internet everywhere. Right?

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.

WiFi Security & Encryption Methods

Open – This is WiFi networks with no authentication. Anyone in the WiFi range can connect his device to the network without any password in enjoy free internet. However, these networks are rarely available and also risky.
WEP – Wired Equivalent Privacy (WEP) is a security protocol, specified in the IEEE Wireless Fidelity (Wi-Fi) standard, 802.11b, that is designed to provide a wireless local area network (WLAN) with a level of security and privacy comparable to what is usually expected of a wired LAN.
WPA – WiFi Protected Access (WPA) is improved and more secured security protocol which arrived with lots of improvements in encryption and authentication methods of WEP.
WPA2 PSK – It is short of Wi-Fi Protected Access 2 – Pre-Shared Key which is the latest and most powerful encryption method used in WiFi networks right now.

Hacking WiFi Networks with WEP, WPA and WPA2 PSK Security

As security features have been improved from WEP to WPA to WPA2 PSK WiFi authentication protocol, so obviously, WEP WiFi networks are very easy to hack compared to WPA and WPA2 PSK Security methods.

Almost every password-protected WiFi networks support both WPA/WPA2 PSK authentication. 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:

It will show you the output like this:

Using the above methods, you should have known the encryption-type of targeted WiFi network which you want to hack. So, I am gonna show you how to hack WiFi Network for each of WEP, WPA and WPA2 PSK secured WiFi networks.

Requirements for Hacking WiFi Netwoks

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. Download Kali Linux ISO from its website either install it as separate operating system in your system or you can use Virtual Machine/VMware to directly run KALI Linux inside Windows.

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. Because if it’s not compatible, you need to have an Aircrack-ng compatible card. Check it directly here: http://www.aircrack-ng.org/doku.php or run aireplay-ng -9 mon0 command inside terminal to view the percentage of injection your card can do.

Install Aircrack-ng using the following command in KALI LINUX

sudo apt-cache search aircrack-ng (to seach aircrack-ng or any related repositories)
sudo apt-get install aircrack-ng (to install aircrack-ng repository)

Fulfill only these requirements and you are ready to hack any WiFi network, whether it is a WEP, WPA or WPA2 PSK Wi-Fi.

Steps to hack WiFi Networks

Starting below, I’ll be guiding you step-by-step in hacking a secured WiFi network. You can either scroll down to read each and every WiFi hacking method or can directly jump to the required section below using these links:

There are various methods to hack into WiFi network and crack its password for all the above security-types but I am showing only those methods with which I’ve had success in cracking password of desired WiFi network and hack secured WiFi Access points. So, if you follow these steps correctly, you’ll also be able to hack any WiFi hotspot available in your reach.

How To Hack WEP WiFi Network

In this method, we are going to hack WEP secured WiFi network using packet injection method inside KALI Linux operating system. So, start KALI Linux in your system. Now follow these below steps:

Step 1: Check Wireless Interface

Open terminal in Kali Linux and enter the command airmon-ng. It will show you what network interface are you using. In my system, I have only one network interface card wlan0, which is my wireless interface card.
Create a network interface which runs in monitor mode. To do this enter command airmon-ng start wlan0.Make sure to replace wlan0 in command with the interface name that your card have. Here, mon0 has been created.
Now, you might or might not get the warning appearing in the below screenshot which tells other processes using the network which can create the problem. So, you can kill them using the syntax: kill PID if you know those processes are not important for you at the moment.

Step 2: Scan available WEP WiFi networks
