WPA passwords have between 8 and 63 Characters - The only known (as of Jan 2010) vulnerability to WPA is a Bruteforce attack. A Bruteforce Attack is simply to try password after password after password. Either precomputed or listed in a file.
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
Wpa Password Recovery
- 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: 826+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
- 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.

WPA/WPA2 cracking has been a focus point in the community since many years. And we have tools to aim that focus like aircrack and hashcat. Some new advancements have been made to aid that focus in the past couple of years.
So, Cracking WPA/WPA2 has been quite a topic now. In this tutorial, we are going to cover one of the infamous tools 'hashcat' for cracking WPA/WPA2.
Hashcat which is primarily built for brute forcing different kind of hashes using different kind of attack vectors, supports cracking for two of badly known WPA/WPA2 attacks. Well, for the list of available hashes, you can check the hash modes section in the manual:
In previous, you might have seen or even worked with aircrack to crack WPA/WPA2 by capturing a 4-way handshake. But that was not anywhere close to how perfect could this tool be for the purpose. Besides, hashcat is a GPU + CPU maintained tool which makes it a lot more faster.
In short, if you own a GPU, always go for hashcat or else you could use an online service or buy out some GPU based server on Internet.
We will cover up with two famous WPA/WPA attacks, precisely the cracking of MIC (4-way handshake) and PMKID (1st packet/handshake). So, let's begin.
Installation
Hashcat is built to work on Windows, Linux and as well as on Mac. You can go to hashcat.net and download the binaries and follow the instruction for your operating system. What we are going to do here is clone a fresh copy of hashcat from github and manually install it on a debain based linux. Pixel gun 3d 7.1 1 apk pc.
Preferably, you should use Kali Or Parrot but a similar distro like Ubuntu will work as well.
Update Your Repo's and install the following dependencies:
Clone hashcat from github and move to directory:
Finally, compile the binaries and we are all set with hashcat.
You may try printing the help manual for hashcat to check whether you have it installed perfectly or not.
Hcxtools:
Now, let's clone and compile hcxtools from github. It is basically a set of various files to convert and generate another version of the supplied input. We will use it to convert the captured traffic into a format understandable by hashcat.
First, clone the repo and move the hcxtools directory:
And finally, run the make command to compile binaries and make necessary changes in path.
After having the requirements installed, we move to the cracking part. Below this, i am dividing the tutorial into two parts, first we will crack the WPA/WPA2 using MIC aka 4-way handshake. While in second, i'll do cracking using PMKID.
PART A
Let's clear how the MIC cracking actually works. So, in this case, we need a valid 4-way handshake. The handshake consists of many keys that are interchanged during the authentication between the client and access point.
These independent keys are used to generate a common key named 'Message Integrity Code (MIC)'. This generated MIC is used to validate the given password by cracker.
The algorithm to compute MIC is quite long and tricky and i've have covered that up in another tutorial here. So, let the cracking begin.
STEP 1
Conversion to hccapx format
Supposing you already have a captured 4-way handshake using some tool like airodump, but you still need the proper format to supply it to hashcat. To convert it to a proper format (hccapx), you need another tool.
There are already some online services that you may use: https://hashcat.net/cap2hccapx/
But still in case you are wondering to do it locally, clone the hashcat-utils repo from github:
Finally, compile the binaries. After compiling, you will have the binaries under same directory. The binary file that we need is cap2hccapx.bin. To make sure, you have it correctly compiled, try to execute the file, it will throw you back the syntax:
So, after having it installed, use the below given syntax to convert the .cap file to .hccapx hashcat capture format.
So, this will generate a file by the name 'hashfile.hccapx', which is what we are going to use with hashcat. Now, you may move to whatever directory you want, since will be cracking the final format now.
STEP 2
Cracking WPA/WPA2 (handshake) with hashcat
With hashcat, there is a possibily of various attack vectors. We could do a straight dictionary attack, brute-force attack, combinator attack or even masks attack, i.e. making rules to find various possibilities of trying different characters at different positions.
Anyhow, let's study the actual cracking of WPA/WPA2 handshake with hashcat.
Dictionary Attack:
As named, you need a wordlist for it to work. Considering you have solid list of possible wifi passphrases, or if not, you can download the famous ones: https://www.wirelesshack.org/wpa-wpa2-word-list-dictionaries.html
Launch the following command for dictionary attack:
- -a: specifies cracking mode. In our case it's dictionary mode and '/path/to/dict.txt' is complete path to the wordlist.
- -m: hash mode. Specifies what type of hash we are dealing with.
In Case You Receive issues regarding Intel CPU or 'No devices found/left', use --force argument to force the usage of your device.
Wpa Password Cracker
Brute-Force Attack:
The Brute-force is different than the dictionary attack. Here, we try to replace every character at every possible position in a specified length from a given charset. For example, in a string of length 8, we can try every character from A-Z at every postion in this string.
That's how brute-forcing works and hence very time-consuming. Launch the following command to start your first attempt for brute-forcing:
- -a: specifies the cracking mode and here the value 3 indicates, we are running a brute-force attack.
- ?d?d?d?d?d?d?d?d: is the brute-forcing rule here. It specifies what kind of values to check, where to replace and also assumes how much time could it take to crack the key.
The above mask i.e. '?d?d?d?d?d?d?d?d' states to check a string of length 8 with a digit at every position. You can study about mask attack here: Hashcat Mask Attack.
PART B
Part A was about the handshake cracking. Whilst now, we are going to crack PMKID with hashcat. The PMKID is located in the 1st packet of 4-way handshake and hence it's kind of more useful because we don't need a complete handshake.
The algorithm to compute PMKID is given which is quite easier than that of MIC.
Let the cracking begin for PMKID.
STEP 1
Getting the PMKID hash
The first thing to proceed with PMKID cracking is the pmkid hash. To generate it we need the first packet of the 4-way handshake. Considering you already have that, we will extract the hash from the captured file.
If you are not aware of how to capture the first packet of 4-way handshake, follow this tutorial.
Let's do the conversion. Execute the below command
This will generate a file by the name pmkid.hash that we will use with hashcat to do the cracking.
STEP 2
Cracking WPA/WPA2 (PMKID) with hashcat
Just like previous part, we will apply the same rules here except for the hash mode argument. The hash mode value for PMKID cracking is 16800.
Dictionary Attack:
As per syntax we have back in the PART A section for dictionary attack, we will use that very same syntax except for the -m argument which defines what kind of hash we want to crack. We will be cracking pmkid (16800) this time.
While this would crack the key by looping through each line given in the wordlist.
Brute-Force Attack:
We will do same here as last section i.e. providing a mask to crack the hash. This time, just to show how powerful these masks could be, i'll use a different one. So, execute the command for brute-force attack:
The above mask will create combinations of string of length 8 with every alphabet at every possible position. And this sounds like a huge combination that may take a lot of time to complete. To make the attack more faster, we can use the GPU.
Recently, after successfully compiling the next generation x265 H.265/HEVC video encoder on Windows, Linux and FreeBSD, I decided to ask for guidance when it comes to compressing Anime (live action will follow at a later time) in the Doom9 forums,.Thing is, I didn't understand all of the knobs x265 has to offer, and some of the convenient presets of x264 didn't exist here (like -tune. X265 and x264 are two different video compression standards that are used to compress video in size but still maintain the quality of the video. X264 is an earlier codec and is used in a lot of videos nowdays and x265 is a newer standard. Now if you want a technical description then according to Wikipedia. X264 vs x265 1080p.
CPU/GPU
Now, getting into CPU/GPU thing, we just need to know that GPU is a lot more faster than CPU and hashcat have the ability to do cracking on your GPU. Hashcat has following three device modes which can be changed via -d argument:
- 1: CPU which is by default, selected.
- 2: GPU
- 3: DSP, Co-processor.
You can use one of these devices according to what's more suitable for you. For example,
To accomplish PMKID attack on GPU. That's it, i.e. cracking WPA/WPA2 via hashcat.
Conclusion
The conclusion that can be drawn out of all above is that hashcat is not just limited for a number of hashes, infact it's applicable to a wide range of hashes and other possibilities including mixes and concatenated strings. We learned to crack WPA/WPA2 using hashcat.
Besides, hashcat is known of it's power, stability and speed by operating on GPU. It also gives us the possibility of mask attack which let us play with possibilities of testing thousand of thousands strings against the hash.
