Once as many IVs as required have been captured using the airodump packet capture utility the resultant [filename].cap file can be imported into aircrack to break the static WEP or WPA-PSK keys.

• Cracking: WEP and WPA PSK (WPA 1 and 2) All tools are command line which allows for heavy scripting. A lot of GUIs have taken advantage of this feature. It works primarily Linux but also Windows, OS X, FreeBSD, OpenBSD, NetBSD, as well as Solaris and even eComStation 2.
• Cracking WPA with oclHashcat. Now that we’ve created the password list and captured the WPA handshake we need to store both files in the oclHashcat folder. Next right click the oclHashcat folder and select “Open Command Prompt Here” to open a command line session. Use the following command to start oclHashcat.

How to Crack a Wpa2-Psk Password with Windows By Unknown on 04:49 It,s very common question on the internet to How to hack a Facebook account password and how to hack a WiFi password. Cracking WPA-PSK/WPA2-PSK with John the Ripper. John is able to crack WPA-PSK and WPA2-PSK passwords. Recent changes have improved performance when there are multiple hashes in the input file, that have the same SSID (the routers 'name' string). The input format is a printable hash, which can either be directly created with john's tool “wpapcap2john” (ships with jumbo) from a packet capture in pcap format as produced by tcpdump, wireshark or airodump-ng; or by doing an intermediate.

To view all available switches:

cd c:aircrack-ng-[version]

aircrack-ng.exe

Basic usage: aircrack -q -n [WEP key length] -b [BSSID] [filename].cap

Breaking WEP

As you can see the capture file in use below (capture1.ivs) was created with airodump capture option “Only capture WEP IVs (y/n)” set to “y” as the resultant file is in the .ivs format. If n had been selected the resultant file would be in the .cap format.

Whilst this will work, we can could have cut down the cracking options for Aircrack-ng by specifying the WEP key length (-n) or by specifying the target AP MAC address (-b) on the command line:

aircrack -a 1 -q -n 128 -b 11:11:11:11:11:11 capture1.ivs (Where 11:11:11:11:11:11 = Target AP’s MAC address)

As you can see aircrack found the WEP key for our 1008195 IV capture file (capture1.ivs) in only 4 seconds.

The capture file itself (capture1.ivs) is included here to test your own aircrack installs (note: the file is a 5.77mb download).

Breaking WPA

In order to be carry out the WPA dictionary attack using aircrack-ng we either have to:

1. Wait for a WPA client to associate to the network (This could take a while)
2. Force a WPA client off the network, forcing it to reassociate.

Either of these two method allows us to capture the WPA handshake, which is what we require to perform a dictionary attack.

The downside to using this Windows version of aircrack-ng is that there are not any freely available tools to perform this attack. So we have to either use a Linux tools (e.g. aireplay or void11) or wait for an association to occur.

Which ever way we gather the WPA handshake we still use the same tool; airodump.

Once we think we have captured the WPA handshake, we simply run the capture file through aircrack for confirmation:

If have confirmed we have the WPA handshake (as above) we can attempt the dictionary attack:

As you can see above aircrack found the WPA PSK of “passphrase”

The capture file itself (capture2.cap) is included here to test your own aircrack installs

In this hi-tech life, we always need a working internet connection to manage both our professional and personal life. The most comfortable way to access internet everywhere anytime is by buying mobile data recharges but they are very expensive. Another good way to connect to free WiFi if it’s luckily available at your workplace, college or home. But everyone is not that lucky.

Everybody might have many fast WiFi hotspots available in their smartphone’s range, but they don’t have access to those WiFi connections because they are password protected and you don’t have access to them so, you can’t use those WiFi hotspot to access internet in your smartphone or laptop. But, what if you can hack a WiFi?

Yes, I am not joking. What if you can hack any WiFi available in your range and crack it’s password to access free and unlimited internet? IMO, if you can learn a way to hack a WiFi network then you can access free internet everywhere. Right?

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.

WiFi Security & Encryption Methods

• Open – This is WiFi networks with no authentication. 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.
• WEP – Wired Equivalent Privacy (WEP) is a security protocol, specified in the IEEE Wireless Fidelity (Wi-Fi) standard, 802.11b, that is designed to provide a wireless local area network (WLAN) with a level of security and privacy comparable to what is usually expected of a wired LAN.
• WPA – WiFi Protected Access (WPA) is improved and more secured security protocol which arrived with lots of improvements in encryption and authentication methods of WEP.
• WPA2 PSK – It is short of Wi-Fi Protected Access 2 – Pre-Shared Key which is the latest and most powerful encryption method used in WiFi networks right now.

Hacking WiFi Networks with WEP, WPA and WPA2 PSK Security

As security features have been improved from WEP to WPA to WPA2 PSK WiFi authentication protocol, so obviously, WEP WiFi networks are very easy to hack compared to WPA and WPA2 PSK Security methods.

Almost every password-protected WiFi networks support both WPA/WPA2 PSK authentication. 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:

It will show you the output like this:

Using the above methods, you should have known the encryption-type of targeted WiFi network which you want to hack. So, I am gonna show you how to hack WiFi Network for each of WEP, WPA and WPA2 PSK secured WiFi networks.

Requirements for Hacking WiFi Netwoks

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. Download Kali Linux ISO from its website either install it as separate operating system in your system or you can use Virtual Machine/VMware to directly run KALI Linux inside Windows.

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. Because if it’s not compatible, you need to have an Aircrack-ng compatible card. Check it directly here: http://www.aircrack-ng.org/doku.php or run aireplay-ng -9 mon0 command inside terminal to view the percentage of injection your card can do.

Install Aircrack-ng using the following command in KALI LINUX

• sudo apt-cache search aircrack-ng (to seach aircrack-ng or any related repositories)
• sudo apt-get install aircrack-ng (to install aircrack-ng repository)

Fulfill only these requirements and you are ready to hack any WiFi network, whether it is a WEP, WPA or WPA2 PSK Wi-Fi.

Steps to hack WiFi Networks

Starting below, I’ll be guiding you step-by-step in hacking a secured WiFi network. 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:

There are various methods to hack into WiFi network and crack its password for all the above security-types but I am showing only those methods with which I’ve had success in cracking password of desired WiFi network and hack secured WiFi Access points. So, if you follow these steps correctly, you’ll also be able to hack any WiFi hotspot available in your reach.

How To Hack WEP WiFi Network

In this method, we are going to hack WEP secured WiFi network using packet injection method inside KALI Linux operating system. So, start KALI Linux in your system. Now follow these below steps:

Step 1: Check Wireless Interface

• Open terminal in Kali Linux and enter the command airmon-ng. 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.

Step 2: Scan available WEP WiFi networks

• Now, enter the command airodump-ng mon0 to scan & list down all the available WiFi networks using created monitor interface (mon0). It can take time to all the available WiFi networks in range.
• Once the process is done,all the available WiFi access points will appear with their important details: BSSID (WiFi Access Point MAC Address), PWR (Signal strength value; the lower, the better), CH (Channel for WiFi), ENC (Encryption type), AUTH, ESSID (Name of WiFi)
• Select the WiFi network with WEP Encryption (ENC) and lowest PWR value.

Step 3: Attack the selected WEP WiFi Network

• Open another terminal concurrently and enter command: aidodump-ng -c 1 -w bell –bssid 64:0F:28:6B:A9:B1 mon0. Here, -c 1 indicates channel number which is 1, -w bell is to write data in file “bell”, –bssid 64:0F:28:6B:A9:B1 is MAC address for my selected WiFi access point and mon0 is monitor interface that was created above. Hit Enter and it will start sending packets (visible in #Data) to the WiFi

• The speed of sending data is very slow but you need to escalate it by attacking the WEP WiFi network. First enter the command airplay-ng -1 0 -a 64:0F:28:6B:A9:B1 mon0 to perform fake authentication (-1 in command) to the network.
• Now we will perform ARP REPLAY Attack to the WiFi network to climb the data to the network at enormous rate. Useairplay-ng -3 -b 64:0F:28:6B:A9:B1 mon0, where -3 is for ARP REPLAY attack. 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.
• In below screenshot the bell-01.cap is the file where data is being stored that we will use to crack the password of this WEP WiFi network once we have enough data (recommended #Data value should be over 35,000).

• Once you have enough data in the file bell-01.cap, run the command aircrack-ng bell-01.cap. It will test all the data values available in key file and automatically show you the key it found by testing data in file.

• You can see in above screenshot that we have successfully cracked the password of targeted WEP WiFi network
• The key found will not be in those text or alphanumeric format that the WiFi owner has created. It will be in hex format but work just fine.
• Now, to use this key, firstly start the processes you have killed in Step 1 above using the command I have used below.

• Finally enter the cracked key 61:32:58:94:98 (without colon) as the password of targeted WEP WiFi Network and it will be connected.

Steps to Hack WPA/WPA2 Secured WiFi Network

Hacking into WPA/WPA2 WiFi Network is very tough, time & resource consuming. The technique used to crack WPA/WPA2 WiFi password is 4-way handshake for which there is a requirement to have at least one device connected to the network.

In WPA/WPA2 security method, the allowed password can have both large and small alphabets, numbers and symbols. And, allowed size of password is 64 characters. On a rough guess, if we consider password to be only 8 characters long and eliminate the use of symbols even then if you want to crack WPA or WPA2 WiFi password, using the brute force method the password combinations will be: 8^26+26+10=62 which is equals to:

• 98079714615416886934934209737619787751599303819750539264

So, even in fastest computer you can manage to use, it’s going to take hours.

Aircrack-ng have all the tools required to crack into WPA/WPA2 PSK WiFi network. It can perform 4-way handshake by disconnecting/connecting the connected device and capturing WPA handshake. It can perform brute-force attack but you can’t hope to crack the password if you have wordlist/dictionary for the password (which is already too big in size) with password inside it. I hate to tell you this but yes, doing it on your own can take forever.

However, there is a tricky way to crack WPA/WPA2 WiFi Password quickly which only requires you to be a bit lucky. The tool is fluxion. Fluxion use same 4-way handshake technique to crack secured WPA/WPA2 WiFi access points password but it doesn’t require you to have dictionary or perform brute force attack. So yes, it’s going to minimize your time to hack WPA or WPA2 WiFi networks password multiple folds.

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.

Steps to crack WPA/WPA2 WiFi Password using Fluxion

Crack Wpa Psk Sous Windows 7

• Scan the networks.
• Capture a handshake (can’t be used without a valid handshake, it’s necessary to verify the password)
• Use WEB Interface *
• Launch a FakeAP instance to imitate the original access point
• Spawns a MDK3 process, which deauthenticates all users connected to the target network, so they can be lured to connect to the FakeAP and enter the WPA password.
• A fake DNS server is launched in order to capture all DNS requests and redirect them to the host running the script
• A captive portal is launched in order to serve a page, which prompts the user to enter their WPA password
• Each submitted password is verified by the handshake captured earlier
• The attack will automatically terminate, as soon as a correct password is submitted

I can understand that not all readers will be able to implement the method after reading such summarized version on hacking WPA/WPA2 PSK WiFi Network. So, below is the video tutorial on cracking WPA2 WiFi Access Point password using Fluxion.
