Wep windows cracking

If your network card is not supported under Windows, one can use a free Linux Live CD to boot the system. BackTrack is probably the most commonly used distribution, since it runs from a Live CD, and has aircrack-ng and a number of related security auduting tools already installed.

If you're using the BackTrack CD aircrack-ng is already installed, with my version of linux it was as simple as finding it with:. The ones we will be using are:. As mentioned above, to capture network traffic wihtout being associated with an access point, we need to set the wireless network card in monitor mode. To do that under linux, in a terminal window logged in as root , type:.

NIC should be stopped before chaning MAC address iwconfig wlan0 mode monitor to set the network card in monitor mode ifconfig wlan0 up to start the network card iwconfig - similar to ifconfig, but dedicated to the wireless interfaces. This step assumes you've already set your wireless network interface in monitor mode. It can be checked by executing the iwconfig command.

Next step is finding available wireless networks, and choosing your target:. To capture data into a file, we use the airodump-ng tool again, with some additional switches to target a specific AP and channel.

Most importantly, you should restrict monitoring to a single channel to speed up data collection, otherwise the wireless card has to alternate between all channels. Assuming our wireless card is mon0, and we want to capture packets on channel 6 into a text file called data:. Running airodump-ng on a single channel targeting a specific access point Notes: You typically need between 20, and 40, data packets to successfully recover a WEP key.

One can also use the "--ivs" switch with the airodump-ng command to capture only IVs, instead of whole packets, reducing the required disk space. However, this switch can only be used if targeting a WEP network, and renders some types of attacks useless. Increase Traffic aireplay-ng - optional step for WEP cracking. An active network can usually be penetrated within a few minutes. However, slow networks can take hours, even days to collect enough data for recovering the WEP key.

The aireplay-ng command should be executed in a separate terminal window, concurrent to airodump-ng. It requires a compatible network card and driver that allows for injection mode.

You may also want to read the information available -here-. To see all available replay attacks, type just: aireplay-ng. WEP cracking is a simple process, only requiring collection of enough data to then extract the key and connect to the network.

You can crack the WEP key while capturing data. In fact, aircrack-ng will re-attempt cracking the key after every packets. Usually, between 20k and 40k packets are needed to successfully crack a WEP key. It may sometimes work with as few as 10, packets with short keys. What this means is, you need to wait until a wireless client associates with the network or deassociate an already connected client so they automatically reconnect.

All that needs to be captured is the initial "four-way-handshake" association between the access point and a client. This can be obtained using the same technique as with WEP in step 3 above, using airodump-ng. You may also try to deauthenticate an associated client to speed up this process of capturing a handshake, using:. Note the last two numbers in brackets [ ACKs] show the number of acknowledgements received from the client NIC first number and the AP second number.

It is important to have some number greater than zero in both. If the first number is zero, that indicates that you're too far from the associated client to be able to send deauth packets to it, you may want to try adding a reflector to your antenna even a simple manilla folder with aluminum foil stapled to it works as a reflector to increase range and concentrate the signal significantly , or use a larger antenna.

Simple antenna reflector using aluminum foil stapled to a manilla folder can concentrate the signal and increase range significantly. For best results, you'll have to place the antenna exactly in the middle and change direction as necessary.

Of course there are better reflectors out there, a parabolic reflector would offer even higher gain, for example. See related links below for some wordlist links.

You can, then execute the following command in a linux terminal window assuming both the dictionary file and captured data file are in the same directory :. INR 6, First, we need to kill all the processes that might interfere with the aircrack-ng suite. It is strongly recommended that these processes be eliminated prior to using the aircrack-ng suite. By default, the wifi card will be set to managed mode so we have to enable monitor mode on the wifi card we are using for attacking.

Now we have to monitor all wireless networks, frequency hopping between all wireless channels. For that:. I am attacking Airtel It is my own network. Now open a new terminal window to disconnect the clients connected to the target network. We have to brute force the WPA handshake file with aircrack-ng we will be doing this brute force with the Rockyou. It by default comes with Kali Linux just needs to be extracted. These types of attacks take too long to crack the password and they are always not successful instead of these attacks you can also use evil twin or pixie dust attack which will take less time and going to give you better results.

Raspberry Pi 3. Raspberry Pi Raspberry Pi Pico. WiFi DDoS. The most comfortable way to access internet everywhere anytime is by buying mobile data recharges but they are very expensive. But everyone is not that lucky. But, what if you can hack a WiFi? Yes, I am not joking. IMO, if you can learn a way to hack a WiFi network then you can access free internet everywhere. 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. 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:. Using the above methods, you should have known the encryption-type of targeted WiFi network which you want to hack. CoWPAtty must calculate the hash for each password in its list before testing, which takes time. Reaver is an open-source password-cracking tool.

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. It uses dictionary attacks, distributed network attacks and other methods to guess WEP Keys. WepDecrypt requires installing some libraries and making the binaries executable.

For this reason, the tool may not be a good choice for novice users. CloudCracker leverages cloud-based resources to crack WPA keys and other types of password hashes. It takes the handshake file and the network name as input and performs the password cracking. CloudCracker has a massive password dictionary, giving it a high probability of cracking weak passwords. The price of cracking a hash depends on the desired priority. Pyrit is a tool for performing brute-force password guessing attacks against IEEE It supports the creation of massive pre-computed rainbow tables of passwords stored in databases.

It accomplishes this through a variety of different attacks including exploitation of vulnerable protocols, phishing attacks, brute-force and dictionary-based password guessing attacks. Fern is available for Windows, Linux and macOS platforms. It operated under a freemium model, where a license is necessary to gain access to the full suite of features. 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. Many Wi-Fi networks use secure encryption protocols, making them more difficult to attack. Tools like Wifiphisher attempt to steal user credentials via phishing attacks.
