First i want to say one thing: don't use WEP encryption for your wireless router. It is too easy to crack. Try to use WPA/WPA2 encryption. It is not bulletproof but it is harder to crack. How easy you can crack a WEP encryption? Harder is to find a compatible wireless adapter :) There are many ways to crack WEP. But now i will tell how to do it on Windows. For that you will need a packet sniffing program (we will use Commview for WiFi) and a program called AirCrack. (adsbygoogle = window.adsbygoogle []).push();
Download and install Commview for WiFi. Commview will install also some drivers so you will have to accept the security warning. Go to Logging tab and set the Directory size to 50000 and the average log size to 100. After that push the Play button and choose from the next window Start Scanning. now we have to wait until the network we want to crack appears. Select the network and click on Capture. Wait until the packet reached 5000 or more click Stop and then go to the folder where the log is saved. Open the log file and export it as Wireshark format.

While the security behind WEP networks was broken in 2005, modern tools have made cracking them incredibly simple. In densely populated areas, WEP networks can be found in surprising and important places to this day, and they can be cracked in a matter of minutes. We'll show you how a hacker would do so and explain why they should be careful to avoid hacking into a honeypot.
Often one of the first wireless attacks a hacker will learn, WEP networks in your area can be tracked down with only a few software tools and cracked with a network adapter supporting packet injection. While WEP cracking has always been relatively straightforward, the simplicity with which it can be found and broken in 2018 brings it firmly into the abilities of even the most novice of hackers.
WEP is a stream cipher which relies on never using the same key twice to provide security. Unfortunately, as demonstrated in several published attacks, an attacker is easily able to force the same key to be used twice by replaying network traffic in a way that forces a tremendous amount of packets to be generated. This allows an attacker to collect the data needed to determine the encryption key and crack the network password outright. With good range and a powerful network adapter, anyone can expect to crack WEP networks in only a few minutes.
The power behind WEP hacking comes from two different parts of the attack: the ability to stimulate traffic even from a busy network and the ability to crack the network password when collecting a certain amount of that traffic. Remember that with WPA, hackers can't even capture a handshake from an empty network, but even an empty WEP network can be attacked with packet injection.
As I previously stated, WEP is extremely simple to crack. Just because it's easy doesn't mean it's legal, so make sure that you have permission to do this to any network you're practicing on before launching this kind of attack. While it's very likely the attack will succeed, and it's good to know this skill, the risk that the network you are attacking is a honeypot is much higher than the average encrypted network. WEP is fundamentally broken, so very few people will choose to use it.
Another thing you should consider is that you will very likely not be the first person to crack that WEP network. Depending on the intentions of the person who got there first, the network could be doing anything from stealing credentials to providing a VPN endpoint for very bad stuff. Because you don't know what could be going on, be very cautious about connecting to networks that could be used for nefarious purposes. If WEP is implemented in a business, cracking WEP is often the first line of attack for a pentester to quickly embarrass their client.s
To crack a WEP network, you'll need to be able to stimulate enough network traffic to cryptographically attack the key. The best way to do this is to use a wireless network adapter that's capable of packet injection. This means our adapter will be able to send forged packets to our target network, allowing us to replay anything that would cause the router to provide the amount of traffic we need.
To start attacking a WEP network, you'll need to find one first. To do so, you'll run a series of filters with Airodump-ng to help you locate only vulnerable networks nearby. Airodump-ng is included in the Aircrack-ng package, so be sure to install it with apt-get install aircrack-ng if you don't already.
While the attack proceeds, Besside-ng will log all of the data it collects in a .cap file for later retrieval. If you experience any problems with Besside-ng or get disconnected, don't worry! You can run Aircrack-ng on the .cap file as you add more data generated by Besside-ng, and all of your collected IVs (initialization vectors) will be there. This means you can come back to the same place at different times and gather more IVs to your .cap file until you can crack them to derive the password by running Aircrack-ng.
To try to crack the WEP network for the information you've gathered, you'll need to call Aircrack-ng with the location of the .cap file as the argument. This is pretty easy since Besside-ng usually stores WEP.cap in the root folder. That means running the command to try cracking the network is usually as seen below.
This will read the .cap file and allow you to select which network you want to crack from the ones Besside-ng has encountered. If you have saved up enough IVs, you can crack the password outright, or you can leave it running while Besside-ng runs, and the attack will be repeated automatically every 5,000 IVs until it succeeds.
There you have it, it only takes a few minutes to break into a WEP network using modern tools like Airodump-ng and Besside-ng in conjunction with an appropriate wireless network adapter. Since WEP cracking is a staple of Wi-Fi hacking, I wanted to be sure we covered it in our intro to Wi-Fi hacking series. Hopefully, you have an understanding of what WEP is, why it's vulnerable, and how to go about actually cracking it.
I hope you enjoyed this guide to hacking WEP Wi-Fi networks! If you have any questions about this tutorial or WEP cracking, feel free to leave a comment or reach me on Twitter @KodyKinzie. We'll be doing more in our Wi-Fi hacking series, so stay tuned.
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.
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. 2ff7e9595c
