Crack wireless network security key windows

Most default keys are not easy to remember and you only enter them once or twice a year. In this article, I will explain where you can find your network security key on your router, access point, or computer if you already have a connection and how you can change it.

The WEP security key is one of the older types of keys that are used for wireless networks. It uses a bit key for encrypting the data between your router and computer. The encryption can be cracked within a minutes, exposing your network to the hacker. Always use WPA2 to protect your home network. There are different scenarios when you are looking for the key for the wireless network.

If you have a device that is already connected to the wireless network then you can find the key in the network settings.

Each device that is connected to wireless network stores the key so it can reconnect automatically when the network comes into range.

If you have a new router or access point then the default wireless network key can most of the time be found on a label on the bottom or back of the device. Unfortunately, each manufacturer is using a different label for it, but look for a key that is labeled with one of the following similar phases:. You will find it close to the Wireless Network Name. Use this key phrase to connect to your wireless network. Follow these steps to recover the key.

If you have a Windows 10 device that is already connected to the wireless network, then you can relatively easily find the network security key in Windows 10 self. Your wireless network is broadcasted to everyone that is in range of your device, so a strong password is important. Now every router or access point is different.

But I will provide you with some of the first steps to log in to your router and give you a general direction. First, we need to know the IP Address of the router.

You can look it up in the manual or find it on your computer. You will see a couple of lines, we are looking for the line Default Gateway and the address behind it. If nothing works then you will have to reset the wireless network. To create a new wireless network, log in to your router or access point and go to the wireless network tab. Remove the old network and create a new one. Make sure you choose a strong password, I recommend using a password manager to keep your passwords safe.

The other option is to reset the whole router. Make sure you look up the default router login credentials and make sure you keep the internet settings at hand.

With some routers, you can create a backup of the configuration, if possible, do that before resetting the device. I hope this article helped to find your network security key. Always make sure you use a strong and unique password for you r wireless network. If you want to know more about setting up your home network, make sure you check this article. Thank you for your help. I had spent too much time hours trying to find it myself. With your help I was able to find it in just a minute or two.

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. Make sure to replace wlan0 in command with the interface name that your card have. Here, mon0 has been created. It has both Linux and Windows versions provided your network card is supported under Windows.

The aircrack-ng site has a comprehensive list of supported network cards available here: NIC chipset compatability list.

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 :.

After that, an offline dictionary attack on that handshake takes much longer, and will only succeed with weak passphrases and good dictionary files. My record time was less than a minute on an all-caps character passphrase using common words with less than 11, tested keys! A modern laptop can process over 10 Million possible keys in less than 3 hours.

This prevents the statistical key-grabbing techniques that broke WEP, and makes hash precomputation more dificult because the specific SSID needs to be added as salt for the hash. There are some tools like coWPAtty that can use precomputed hash files to speed up dictionary attacks. Those hash files can be very effective sicne they're much less CPU intensive and therefore faster , but quite big in size.

The external PIN exchange mechanism is susceptible to brute-force attacks that allow for bypassing wireless security in a relatively short time few hours. The only remedy is to turn off WPS, or use an updated firmware that specifically addresses this issue. To launch an attack:. Set your network adapter in monitor mode as described above, using:. Alternatively, you can put your network card in monitor mode using: airmon-ng start wlan0 this will produce an alternate adapter name for the virtual monitor mode adapter, usually mon0.

Before using Reaver to initiate a brute-force WPS attack, you may want to check which access points in the area have WPS enabled and are vulnerable to the attack.
