Hack wep using vista




















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. Now, you might or might not get the warning appearing in the below screenshot which tells other processes using the network which can create the problem.

So, you can kill them using the syntax: kill PID if you know those processes are not important for you at the moment.

It can take time to all the available WiFi networks in range. First enter the command airplay-ng -1 0 -a FB:A9:B1 mon0 to perform fake authentication -1 in command to the network.

Hit enter and the command will start doing attack to WEP WiFi Access point and you can see the Data value increasing at enormously fast rate.

J Jun, admin. Older Comments. I got stuck at step 3. Any suggestions? What is channel name where i can find that stuff in wepcracking? Hello subash. Thanks, Eg. Hi bad, Yes, the best place to ask questions is the forum. Thanks Eg.

You missed. 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. You can identify them using the "wash" Reaver command as follows:. Run Reaver it only requires two inputs: the interface to use, and the MAC address of the target.

There are a number of other parameters that one can explore to further tweak the attack that are usually not required, such as changing the delay between PIN attempts, setting the tool to pause when the access point stops responding, responding to the access point to clear out failed attempts, etc. The above example adds "-vv" to turn on full verbose mode, you can use "-v" instead for fewer messages. Reaver has a number of other switches check with --help , for example " -c11" will manually set it to use only channel 11, " --no-nacks" may help with some APs.

Spoof client MAC address if needed. Reaver supports MAC spoofing with the --mac option, however, for it to work you will have to change the MAC address of your card's physical interface wlan0 first, before you specify the reaver option to the virtual monitor interface usually mon0. To spoof the MAC address:. Note that some routers may lock you out for a few minutes if they detect excessive failed WPS PIN attempts, in such cases it may take over 24 hours. Common pins are , , , etc. Reaver attempts known default pins first.

Reaver comilation requires libpcap pcap-devel and sq3-devel sqlite3-dev installed, or you will get a "pcap library not found" error. Here are some points to consider:. Is your adapter properly set in monitor mode? Does the adapter driver support injection is aireplay-ng working?

Do you have a good signal to the AP? Do you see associated clients for WPA handshake capture? As demonstrated above, WEP cracking has become increasingly easier over the years, and what used to take hundreds of thousands packets and days of capturing data can be accomplished today within 15 minutes with a mere 20k data frames. Simply put, cracking WEP is trivial. However, weak passphrases are vulnerable to dictionary attacks. An extensive list of vulnerable devices is available here: google docs spreadsheet.

Username: Password: forgot password? Home » Articles » Security. Yes, the aircrack suite will work under Vista as well. All commands need to be ran under "elevated command prompt" admininstrator priviledges , or you need to have UAC User Account Control turned off. The only potential problem under Windows is that fewer network adapters have compatible drivers that support monitor mode.

Do I need to install any drivers? Or does it simply not work with my Laptop's Wirless Card. Greetings Timothy. Intel wireless cards don't play well with Linux.

Consider getting a D-Link card that uses an Atheros chipset or get any other Atheros based card. While it is true that Atheros-based NICs have the widest support, latest linux kernels have improved Intel-based support. I have had no problem running aircrack with my Intel agn wireless NIC as mentioned in the article.
