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. My methods require KALI Linux which is especially designed Linux distrbution for penetration testing and ethical hacking. You can download it for free from its official site.
You will also need Aircrack-ng which is a security suite to assess WiFi network security. 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. 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. To show me a wirless interface attached to your computer, you need to type: iwconfig. Good luck. When using backtrack 3 on my sony VGN-TZC which has the same network card chipset I got the "ERROR: Neither the sysfs interface links nor the iw command is available" when running airmon-ng start wlan0 it tells me to install iw but I found no easy way to install it. Then again i'm running backtrack 3 from my usb dongle, I did not nor know how to install the image to the USB so I beleive the installation is readonly.
Thanks for pointing me in the right direction. Thanks for the article Phillip, I was wondering does one need to install a Linux OS on the machine or can it be done from Virtual Box or similar software? Phillip, When I attempt to capture after entering the commands I get the following message: "airodump-ng --help" for help Nor is there a data file in my home folder, do you have any idea what I'm doing wrong?
Its possible crack the wires founded by my ap? I was getting the same error but made it work by typing airodump-ng --channel 6 --bssid F:CC:7D:5A -w data mon0 This should work. Very clear instructions. Does it work with Mac OS X? Greetings from London. When I do the aireplay --deauth command, is there any indication that would tell me if it worked or not? Speed guide? The lights are on. Is anybody really home?
You can hide, and have hidden, behind the letter of the law. Publishing this information is ethically criminal. Your disclaimer clearly indicates you understand people will use this information to do what ought not to be done. Namely hacking into networks not their own. Shame on you speed guide! Security by obscurity is not a sound principle in our book.
In other words, the notion that unknown security flaws are unlikely to be found by attackers is false. WEP, for example, has very well known exploits, and anyone serious about securing their network should be aware of the extent of such flaws.
The article above merely informs readers how this is accomplished, therefore allowing them to make more educated choices when choosing encryption methods. Phillip, You have only to look at all the other posts here, in order to clearly understand what is happening. Others posting here are helping each other hack private networks not protect themselves , whether you do or do not acknowledge this it doesn't change the truth of the matter.
Inormation can be used in different ways. The fact that there exists the possibility of it being used unethically does not justify hiding it, and does not make it "shameful". The best article I have read on using the aircrack suite. Thanks for posting, this information needs to be known.
Dear Writer, I am extremely thankful to you for this informative, clean, pin pointed and easy to understand tutorial. It worked for me as piece of cake.
