Cracking is the process of exploiting security weaknesses in wireless networks and gaining unauthorized access. WEP cracking refers to exploits on networks that use WEP to implement security controls. There are basically two types of cracks namely;
WPA uses a 256 pre-shared key or passphrase for authentications. Short passphrases are vulnerable to dictionary attacks and other attacks that can be used to crack passwords. The following WiFi hacker online tools can be used to crack WPA keys.
It is possible to crack the WEP/WPA keys used to gain access to a wireless network. 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.
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. We will also provide useful information that can be used to crack the WEP and WPA keys of wireless networks.
This tutorial walks you through cracking WPA/WPA2 networks which use pre-shared keys. I recommend you do some background reading to better understand what WPA/WPA2 is. The Wiki links page has a WPA/WPA2 section. The best document describing WPA is Wi-Fi Security - WEP, WPA and WPA2. This is the link to download the PDF directly. The WPA Packet Capture Explained tutorial is a companion to this tutorial.
WPA/WPA2 supports many types of authentication beyond pre-shared keys. aircrack-ng can ONLY crack pre-shared keys. So make sure airodump-ng shows the network as having the authentication type of PSK, otherwise, don't bother trying to crack it.
There is another important difference between cracking WPA/WPA2 and WEP. This is the approach used to crack the WPA/WPA2 pre-shared key. Unlike WEP, where statistical methods can be used to speed up the cracking process, only plain brute force techniques can be used against WPA/WPA2. That is, because the key is not static, so collecting IVs like when cracking WEP encryption, does not speed up the attack. The only thing that does give the information to start an attack is the handshake between client and AP. Handshaking is done when the client connects to the network.Although not absolutely true, for the purposes of this tutorial, consider it true. Since the pre-shared key can be from 8 to 63 characters in length, it effectively becomes impossible to crack the pre-shared key.
The only time you can crack the pre-shared key is if it is a dictionary word or relatively short in length. Conversely, if you want to have an unbreakable wireless network at home, use WPA/WPA2 and a 63 character password composed of random characters including special symbols.
IMPORTANT This means that the passphrase must be contained in the dictionary you are using to break WPA/WPA2. If it is not in the dictionary then aircrack-ng will be unable to determine the key.
In the response above, you can see that ath0 is in monitor mode, on the 2.452GHz frequency which is channel 9 and the Access Point shows the MAC address of your wireless card. Only the madwifi-ng drivers show the card MAC address in the AP field, other drivers do not. So everything is good. It is important to confirm all this information prior to proceeding, otherwise the following steps will not work properly.
Here, mon0 is seen as being in monitor mode, on channel 9 (2.452GHz). Unlike madwifi-ng, the monitor interface has no Access Point field at all. Also notice that wlan0 is still present, and in managed mode - this is normal. Because both interfaces share a common radio, they must always be tuned to the same channel - changing the channel on one interface also changes channel on the other one.
The purpose of this step is to actually crack the WPA/WPA2 pre-shared key. To do this, you need a dictionary of words as input. Basically, aircrack-ng takes each word and tests to see if this is in fact the pre-shared key.
WEP and WPA are the two main security protocols used in Wi-Fi LAN. WEP, or Wired Equivalent Privacy, is a deprecated security protocol that was introduced back in 1997 as a part of the original 802.11 standards. However, it was weak, and several serious weaknesses were found in the protocol. Now, this can be cracked within minutes.
To get unauthorized access to a network, one needs to crack these security protocols. Many tools can crack Wi-Fi encryption. These tools can either take advantage of WEP weaknesses or use brute force password guessing attacks on WPA/WPA2/WPA3.
Wireless hacking tools are of two types. One can be used to sniff the network and monitor what is happening in the network. The other kind of tool is used to hack WEP/WPA keys. 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 802.11a/b/g WEP and WPA cracking. 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. It comes as Linux distribution, Live CD and VMware image options. 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. In this case, try Live CD or VMWare image. VMWare Image needs less knowledge, but it only works with a limited set of host OS, and only USB devices are supported.
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.
AirJack is a Wi-Fi 802.11 packet injection tool. 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.
CloudCracker is an online password cracking tool for cracking WPA-protected Wi-Fi 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. This tool has a huge dictionary of around 300 million words to perform attacks.
Wireless networks are common in enterprise environments, making them a prime target for penetration testers. Additionally, misconfigured wireless networks can be easily cracked, providing penetration testers with a great deal of valuable information about the network and its users. This article explores some of the most widely-used tools for different aspects of wireless network hacking.
KisMac, as its name suggests, is designed to be a Kismet clone available on macOS. Like Kismet, KisMac performs passive network monitoring and can attempt to crack WEP and WPA keys using brute force password guessing or exploiting known flaws in legacy protocols.
Wireless networks use encryption to protect the data they carry against eavesdropping and malicious modifications. However, legacy encryption protocols (like WEP) are vulnerable to attack, and even secure protocols can be cracked using brute-force and dictionary-based attacks. Several different tools exist for cracking the passwords securing Wi-Fi networks.
Aircrack-ng is a popular wireless password-cracking tool. It starts by capturing wireless network packets, then attempts to crack the network password by analyzing them. Aircrack-ng supports FMS, PTW, Korek and other attacks against WEP passwords. Aircrack-ng can also use dictionary attacks to guess passwords for WPA, WPA2 and WPA3 Wi-Fi networks.
For Wi-Fi networks with one of about 1,000 of the most common and default SSIDs, CoWPAtty offers a rainbow table of 172,000 password hashes. If a particular Wi-Fi network uses one of these SSIDs and has a password in the list, then CoWPAtty can crack it much more quickly.
Wifite is a tool designed to simplify the Wi-Fi auditing process. It runs existing tools for you to eliminate the need to memorize command-line switches and how to configure various tools. To learn more about using wifite, read the wifite walkthrough.
Fern Wifi Wireless Cracker is designed to crack WEP/WPA/WPA/WPA2 keys on Wi-Fi networks. It accomplishes this through a variety of different attacks including exploitation of vulnerable protocols, phishing attacks, brute-force and dictionary-based password guessing attacks.
Airgeddon is a script designed to run other network monitoring and cracking scripts. For example, Airgeddon requires Aircrack-ng to run. By configuring and executing these scripts for the user, Airgeddon can make Wi-Fi cracking easier to perform.
In 1999, the WEP (Wired Equivalent Privacy) was introduced. It was deprecated in 2004 after some researchers discovered flaws in the design of the protocol. Currently, it is really easy to crack a WEP password. With the right tools, it requires only a few minutes.
Most of these fields are important during the handshake, but we are specifically interested by the key nonce and key MIC fields in order to crack the pass-phrase. For more information about the EAPOL frame, see [3] and [4]
Several tools can be used to perform this attack. The suite of tools Aircrack-ng provides all elements necessary to crack a password (airodump-ng for capturing packets, aircrack-ng to perform a dictionary attack, airdecap-ng to decrypt packets).
Different tools are available to crack the handshake. It is possible to do that with aircrack-ng, Pyrit project or hashcat. We used hashcat [9] (a tool to recover many different types of hashes) because it is very well documented, very powerful, supports a lot of different hardware and uses multi-threads. 2b1af7f3a8
