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. 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:.
Now follow these below steps:. And, allowed size of password is 64 characters. I hate to tell you this but yes, doing it on your own can take forever. The tool is fluxion. Instead of doing this, it performs a little bit of phishing where the already connected user is asked to enter password of WiFi network again for security reason and when the user enter the password, first the handshake is checked with the earlier captured handshake of the device, if handshake is correct that means the password entered by user is correct.
Once it is successful, Fluxion returns the key required to authenticate the network. 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. 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.
It is also more effective than passive cracking. Aircrack — This is a network sniffer and a WEP cracker. FMS attack is implemented through this. Kismet - It detects the wireless networks which are visible as well as the hidden, sniffer packets and also detects intrusions.
It has key generators of its own and it implements packet filters for hacking WiFi passwords. For authentications, WPA uses a pre-shared key or passphrase. Mostly, if short passphrases are used, they become vulnerable to dictionary attacks. The mentioned Wifi hacker tools can be used to crack the WPA keys. Sniffing — Sniffing involves the intercepting of packets as they are transmitted over a network. Then the captured data is decoded using tools such as Cain and Abel.
Denial of Service Attack — This attack is mainly to deny the legitimate users, network resources. This type of attack can be performed using FataJack. All you need are the hardware and software resources and some patience. These attacks also depend on the activity of the users of the network to be cracked. Backtrack is an operating system that is Linux-based and developed on top of Ubuntu.
It comes with a number of security tools and can be used to gather information, trace the vulnerabilities and then exploit the network. If the users of the target network are very frequent and active on their network, then you will have considerably more chances to crack it. You have to have a basic knowledge of Linux-based operating systems and also a little bit of knowledge about Airrack and its different scripts.
You can restrict access to the network by allowing only the registered MAC addresses. Make sure your decoders tab is selected and then click the Wireless Passwords from the menu on the left side. If prior to this you have connected to a wireless network, then you will see results similar to the ones shown below. Then you will see the encryption type, SSID, and the password shown to you by the decoder.
Learn CSS. Learn JavaScript. C Language C Tutorial. C Compiler. Standard Template Library. Python Python Tutorial. Python Programs. Python How Tos. Numpy Module. Matplotlib Module. Tkinter Module. Network Programming with Python. The implementation is done at the Layer 1 physical layer of the OSI model. You will need a wireless network enabled device such as a laptop, tablet, smartphones, etc.
You will also need to be within the transmission radius of a wireless network access point. Most devices if the wireless network option is turned on will provide you with a list of available networks.
If the network is not password protected, then you just have to click on connect. If it is password protected, then you will need the password to gain access. Since the network is easily accessible to everyone with a wireless network enabled device, most networks are password protected. It was developed for IEEE Its goal was to provide the privacy equivalent to that provided by wired networks. WEP works by encrypting the data been transmitted over the network to keep it safe from eavesdropping.
Open System Authentication OSA — this methods grants access to station authentication requested based on the configured access policy. The station encrypts the challenge with its key then responds. If the encrypted challenge matches the AP value, then access is granted. It is used to encrypt data on It uses temporal keys to encrypt packets. Cracking is the process of exploiting security weaknesses in wireless networks and gaining unauthorized access.
There are basically two types of cracks namely;.
