Poor encryption is related to security keys used to protect the wireless network. WEP, or Wired Equivalent Privacy, is a deprecated security protocol that was introduced back in as a part of the original However, it was weak, and several serious weaknesses were found in the protocol.
Now, this can be cracked within minutes. A new Wi-Fi security protocol was introduced in To get unauthorized access to a network, one needs to crack these security protocols.
Many tools can crack Wi-Fi encryption. Wireless hacking tools are of two types. One can be used to sniff the network and monitor what is happening in the network.
These are the popular tools used for wireless password cracking and network troubleshooting. Aircrack-ng is one of the most popular wireless password cracking tools that you can use for Aircrack-ng uses the best algorithms to recover wireless passwords by capturing packets. Once enough packets have been gathered, it tries to recover the password.
To make the attack faster, it implements a standard FMS attack with some optimizations. The company behind the tool also offers an online tutorial where you can learn how to install and use this tool to crack wireless passwords. You can use any of these. It supports most of the wireless adapters and is almost guaranteed to work.
If you are using a Linux distribution, the only drawback of the tool is that it requires deeper knowledge of Linux. If you are not comfortable with Linux, you will find it hard to use this tool. Before you start using this too, confirm that the wireless card can inject packets.
Then start WEP cracking. Read the online tutorial on the website to know more about the tool. If you follow the steps properly, you should be able to successfully crack a Wi-Fi network protected with WEP. Wifite is a Python script designed to simplify wireless security auditing.
It runs existing wireless hacking tools for you, eliminating the need to memorize and correctly use the different tools with their various options. Wifite2 is a complete rewrite of the original Wifite tool. Before running Wifite, it is recommended to install their optional tools as they are essential for running some of the supported attacks. It passively collects packets being broadcast in its vicinity and analyzes them to detect even hidden Wi-Fi networks.
Kismet is supported on all operating systems using WSL on Windows and is actively supported. The last release significantly re-architected the system to improve performance and add new features. Wifiphisher is a tool designed to perform man-in-the-middle attacks by exploiting Wi-Fi association.
By convincing wireless users to connect to the rogue access point, Wifiphisher provides an attacker with the ability to intercept and monitor or modify their wireless traffic. Wifiphisher also enables an attacker to launch web phishing attacks. These can be used to collect user credentials for third-party sites or Wi-Fi network credentials. Additionally, Wifiphisher is designed to be modular, enabling advanced users to write custom code to expand its capabilities. Basic functionality is available for free, but certain features require a paid membership.
Wireshark is the network protocol analyzer. It lets you check what is happening in your network. You can capture packets live and inspect them at a high level or see the values of particular fields within a packet. Wireshark is designed to be user-friendly but has a great deal of functionality under the hood. It is most useful if you have a strong understanding of network protocols and can effectively interpret the traffic that you are seeing. It runs on Linux OS. This program has a command-line interface and runs on a word list that contains the password to use in the attack.
Using the tool is simple, but it is slow. Since each calculation of PBKDF takes time, this makes a brute force password guessing attack very slow. However, CoWPAtty does have a rainbow table designed to mitigate this issue.
If the target network is one of these, testing it against the precomputed dictionary is much faster. AirJack is a Wi-Fi This wireless cracking tool is very useful in injecting forged packets and taking a network down via a denial of service attack.
This tool can also be used for a man-in-the-middle attack on the network. Airgeddon is designed to be an all-in-one tool for security analysis of wireless networks.
To accomplish this, it integrates several existing tools and provides a single command-line interface for all of them. OmniPeek is another nice packet sniffer and network analyzer tool. This tool is commercial and supports only Windows operating systems. OmniPeek is included on this list despite being a commercial tool due to the extensive feature set. This tool is intended to be an all-in-one Wi-Fi network management solution and includes packet capture, protocol decoding, network diagnostics and troubleshooting and even playback and analysis of voice and video traffic for diagnostic purposes.
CommView for WiFi is another popular wireless monitor and packet analyzer tool. It comes with an easy-to-understand GUI. It works fine with It captures every packet and displays useful information as a list. You can get useful information like access points, stations, signal strength, network connections and protocol distribution.
This tool is basically for Wi-Fi network admins, security professionals, home users who want to monitor their Wi-Fi traffic and programmers working on software for wireless networks. This tool can also be used to crack different password hashes. Just upload the handshake file, enter the network name, and start the tool.
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;. WPA uses a pre-shared key or passphrase for authentications. Short passphrases are vulnerable to dictionary attacks and other attacks that can be used to crack passwords. Doing so requires software and hardware resources, and patience. The success of such WiFi password hacking attacks can also depend on how active and inactive the users of the target network are.
We will provide you with basic information that can help you get started. Backtrack is a Linux-based security operating system. It is developed on top of Ubuntu. Backtrack comes with a number of security tools. Backtrack can be used to gather information, assess vulnerabilities and perform exploits among other things. Cracking wireless network keys requires patience and resources mentioned above.
At a minimum, you will need the following tools. In this practical scenario, we are going to learn how to crack WiFi password. We will use Cain and Abel to decode the stored wireless network passwords in Windows. Skip to content. Guru99 is Sponsored by Netsparker. Netsparker, the developers of Proof Based Scanning technology, have sponsored the Guru99 project to help raise web application security awareness and allow more developers to learn about writing secure code.
