This is a tutorial on how to crack WPA WPA2 with aircrack. WPA stands for Wifi Protected Access. It is an encryption system to secure WLAN networks. It eliminates all known vulnerabilites in WEP(Wired Equivalent Privacy).  WPA uses 128 bit key and  48 bit initialization vector while WEP uses 108 bit key with 24 bit initialization vector. WPA2 is the successor of WPA. Both WPA and WPA2 use temporal key integrity protocol(TKIP) for encryption and  pre-shared key(PSK) authentication.  The only difference between WPA and WPA2 is that they use Rivest Cipher(RC4) and Advanced Encryption Standard(AES) encryption algorithms respectively. Both can be configured to use counter cipher block chaining mode(CCM) though. They are by far consired  most secure for Wifi networks.

So, today we are going to see WPA/WPA2 password cracking with aircrack. For this howto, I am going to use Kali Linux. ( For this howto, if you are running Kali Linux in Vmware or Virtualbox you need to have a compatible wifi usb adapter). I am running Kali Linux in live USB mode(see how to make kali live usb) as my laptop has Atheros adapter. So let’s start.

Once you have booted into Kali Linux, open terminal and type command “iwconfig”. It lists your wireless interfaces just like ifocnfig shows wired interfaces.

We can see that we have a wireless interface wlan0. Now we are going to start monitor mode on our wireless interface. Monitor mode is same as promiscuous mode in wired sniffing. Type command “airmon-ng start wlan0″. We can see below that monitor mode has been enabled on “mon0″.

Now let’s see all the traffic collected by our wireless interface. Type command airodump-ng mon0.

Hit Enter. We can see all the wireless networks available as shown below.

We can see that all the wifi networks are configured with  WPA2 or WPA. We are going to hack the network “shunya”. We will collect the shunya’s network traffic into a file. Open a terminal and type command “airodump-ng –bssid <Mac address of wifi access point> -c 13 –write wpacrack mon0″.


–bssid stands for base station security identifier

<MAC address> is the Mac address of access point.

-c is used to specify the channel the wifi network is operating on.

–write to write to a file.

wpacrack  is the file name we are writing into.

mon0 is the interface

Hit Enter. We will see the result as below.

We can only hack a WPA/WPA2 protected wifi network by capturing it’s handshake process or association( when the client is trying to connect to the wifi network.).  So let’s try to disconnect all the clients connected to the wifi network “shunya” first. Open a new terminal and type the command “aireplay-ng  –deauth 100 -a <MAC> –ignore-negative-one mon0″.


–deauth are the deauthentication packets,

100 are the number of deauthentication packets we want to send.

-a stands for access point.

<MAC> is the MAC address of the wifi access point.

This command will send 100 deauthentication packets to the broadcast address of the wifi access point. This will make all the clients connected to the shunya get disconnected. As soon as this happens, all the clients will try to connect back to the wifi network once again. We can see that a WPA handshake has happened in the previous terminal.

Now let’s see where our capture file is located. Type “ls”. We will do dictionary password cracking here. So let’s find out where the dictionaries are.  Type command “locate wordlists”. This will show us a number of wordlists available by default in kali linux.

Our captured traffic is stored in .cap file. We will use the wordlist big.txt for cracking the password. Open a new terminal and type command “aircrack-ng wpacrack-01.cap -w /usr/share/dirb/wordlists/big.txt”.

Hit Enter. If our dictionary has the password, the result will be as below. If our dictionary doesn’t have the password, we have to use another dictionary.

Remember that the choice of dictionary will play a key role in WPA/WPA2 password cracking. So that is one way in which we crack wpa wpa2 password  with aircrack for you. Hope this was helpful. Learn how to crack wpa wpa2  with a graphical tool.

How to Hack WiFi (Wireless) Network

Wireless networks are accessible to anyone within the router’s transmission radius. This makes them vulnerable to attacks. Hotspots are available in public places such as airports, restaurants, parks, etc.

In this tutorial, we will introduce you to common techniques used to exploit weaknesses in wireless network security implementations. We will also look at some of the countermeasures you can put in place to protect against such attacks.

Topics covered in this tutorial


What is a wireless network?

A wireless network is a network that uses radio waves to link computers and other devices together. The implementation is done at the Layer 1 (physical layer) of the OSI model.

How to access a wireless network?

You will need a wireless network enabled device such as a laptop, tablet, smartphones, etc. You will also need to be within the transmission radius of a wireless network access point. Most devices (if the wireless network option is turned on) will provide you with a list of available networks. If the network is not password protected, then you just have to click on connect. If it is password protected, then you will need the password to gain access.

Wireless Network Authentication

Since the network is easily accessible to everyone with a wireless network enabled device, most networks are password protected. Let’s look at some of the most commonly used authentication techniques.


WEP is the acronym for Wired Equivalent Privacy. It was developed for IEEE 802.11 WLAN standards. Its goal was to provide the privacy equivalent to that provided by wired networks. WEP works by encrypting the data been transmitted over the network to keep it safe from eavesdropping. 

WEP Authentication

Open System Authentication (OSA) – this methods grants access to station authentication requested based on the configured access policy.

Shared Key Authentication (SKA) – This method sends to an encrypted challenge to the station requesting access. The station encrypts the challenge with its key then responds. If the encrypted challenge matches the AP value, then access is granted.

WEP Weakness

WEP has significant design flaws and vulnerabilities.

  • The integrity of the packets is checked using Cyclic Redundancy Check (CRC32). CRC32 integrity check can be compromised by capturing at least two packets. The bits in the encrypted stream and the checksum can be modified by the attacker so that the packet is accepted by the authentication system. This leads to unauthorized access to the network.
  • WEP uses the RC4 encryption algorithm to create stream ciphers. The stream cipher input is made up of an initial value (IV) and a secret key. The length of the initial value (IV) is 24 bits long while the secret key can either be 40 bits or 104 bits long. The total length of both the initial value and secret can either be 64 bits or 128 bits long.The lower possible value of the secret key makes it easy to crack it.
  • Weak Initial values combinations do not encrypt sufficiently. This makes them vulnerable to attacks.
  • WEP is based on passwords; this makes it vulnerable to dictionary attacks.
  • Keys management is poorly implemented. Changing keys especially on large networks is challenging. WEP does not provide a centralized key management system.
  • The Initial values can be reused

Because of these security flaws, WEP has been deprecated in favor of WPA


WPA is the acronym for Wi-Fi Protected Access. It is a security protocol developed by the Wi-Fi Alliance in response to the weaknesses found in WEP. It is used to encrypt data on 802.11 WLANs. It uses higher Initial Values 48 bits instead of the 24 bits that WEP uses.  It uses temporal keys to encrypt packets.

WPA Weaknesses

  • The collision avoidance implementation can be broken
  • It is vulnerable to denial of service attacks
  • Pre-shares keys use passphrases.  Weak passphrases are vulnerable to dictionary attacks.

How to Crack Wireless Networks

WEP cracking

Cracking is the process of exploiting security weaknesses in wireless networks and gaining unauthorized access. WEP cracking refers to exploits on networks that use WEP to implement security controls. There are basically two types of cracks namely;

  • Passive cracking– this type of cracking has no effect on the network traffic until the WEP security has been cracked. It is difficult to detect.
  • Active cracking– this type of attack has an increased load effect on the network traffic. It is easy to detect compared to passive cracking. It is more effective compared to passive cracking.

WEP Cracking Tools

WPA Cracking

WPA uses a 256 pre-shared key or passphrase for authentications. Short passphrases are vulnerable to dictionary attacks and other attacks that can be used to crack passwords. The following tools can be used to crack WPA keys.

General Attack types

  • Sniffing– this involves intercepting packets as they are transmitted over a network. The captured data can then be decoded using tools such as Cain & Abel.
  • Man in the Middle (MITM) Attack– this involves eavesdropping on a network and capturing sensitive information.
  • Denial of Service Attack– the main intent of this attack is to deny legitimate users network resources. FataJack can be used to perform this type of attack. More on this in article

Cracking Wireless network WEP/WPA keys

It is possible to crack the WEP/WPA keys used to gain access to a wireless network. Doing so requires software and hardware resources, and patience. The success of such attacks can also depend on how active and inactive the users of the target network are.

We will provide you with basic information that can help you get started. Backtrack is a Linux-based security operating system. It is developed on top of Ubuntu. Backtrack comes with a number of security tools. Backtrack can be used to gather information, assess vulnerabilities and perform exploits among other things.

Some of the popular tools that backtrack has includes;

  • Metasploit
  • Wireshark
  • Aircrack-ng
  • NMap
  • Ophcrack

Cracking wireless network keys requires patience and resources mentioned above. At a minimum, you will need the following tools

A wireless network adapter with the capability to inject packets (Hardware)

  • Kali Operating System. You can download it from here https://www.kali.org/downloads/
  • Be within the target network’s radius. If the users of the target network are actively using and connecting to it, then your chances of cracking it will be significantly improved.
  • Sufficient knowledge of Linux based operating systems and working knowledge of Aircrack and its various scripts.
  • Patience, cracking the keys may take a bit of sometime depending on a number of factors some of which may be beyond your control. Factors beyond your control include users of the target network using it actively as you sniff data packets.


How to Secure wireless networks

In minimizing wireless network attacks; an organization can adopt the following policies

  • Changing default passwords that come with the hardware
  • Enabling the authentication mechanism
  • Access to the network can be restricted by allowing only registered MAC addresses.
  • Use of strong WEP and WPA-PSK keys, a combination of symbols, number and characters reduce the chance of the keys been cracking using dictionary and brute force attacks.
  • Firewall Software can also help reduce unauthorized access.

Hacking Activity: Crack Wireless Password

In this practical scenario, we are going touse Cain and Abel to decode the stored wireless network passwords in Windows. We will also provide useful information that can be used to crack the WEP and WPA keys of wireless networks.

Decoding Wireless network passwords stored in Windows

  • Download Cain & Abel from the link provided above.
  • Open Cain and Abel

  • Ensure that the Decoders tab is selected then click on Wireless Passwords from the navigation menu on the left-hand side
  • Click on the button with a plus sign

  • Assuming you have connected to a secured wireless network before, you will get results similar to the ones shown below


  • The decoder will show you the encryption type, SSID and the password that was used.



  • Wireless network transmission waves can be seen by outsiders, this possesses many security risks.
  • WEP is the acronym for Wired Equivalent Privacy. It has security flaws which make it easier to break compared to other security implementations.
  • WPA is the acronym for Wi-Fi Protected Access. It has  security compared to WEP
  • Intrusion Detection Systems can help detect unauthorized access
  • A good security policy can help protect a network.

WiFi / Wireless Hacking Tools

Content Written By Henry Dalziel, 2020

WiFi Hacker Tools That Work In 2020

WiFi (‘Wireless’) hacking is all the rage.

For reasons best known to psychologists, it seems that WiFi Hacking is the most popular ‘hacking related content’ on YouTube.

Some WiFi Hacking Videos on YouTube have literally millions of views. Perhaps Hacking WiFi is so popular because, firstly, it means that if you master the attacks you’ll be able to secure endless free WiFi, but, secondly, because it is something which appeals and a ‘rite of passage’ for any budding wanna-be Hacker or serious Cybersecurity Professional.

Needless to say, to Hack WiFi is an achievement (if it has been configured absolutely correctly using, for example, WPA2 Enterprise) and the skills required to defend against such attacks are highly in demand, so to satisfy your curiosity we’ve gone ahead and listed a bunch of WiFi Hacking Software Tools that the Interwebs seems to have fallen in love with!

One thing is for sure though when it comes to WiFi Hacking, if you want to become a Cybersecurity Professional, not least a SysAdmin or similar then you will absolutely have to know and understand Wireless technologies.

To understand it means to also hack it and penetrate the network. Once you understand how you’ve been able to hack into the network then, of course, you can patch it.


By far the most popular and best-known tool (actually it is a “suite” of tools) when it comes to hacking WiFi. In fact, this is an old-school tool that has been around for ages.

This Wireless Hacking Tool is actually a suite and has various different entities within the package. This tool actually ships with Kali Linux and for most Penetration Testers is considered as “the go-to” tool when it comes to testing clients’ WiFi networks.

Aircrack is a “must-learn” if you are serious about a career as a network engineer or Penetration Tester.


This tool is fantastic and being able to attack multiple WEP, WPA, and WPS encrypted networks in a row. It’s fast becoming the industry’s favorite WiFi Hacking Tool for Pentesters.

If you just need “one” tool to test your clients’ Wireless Network for security vulnerabilities. If you need a tool to get going and test your WiFi Hacking Skills, then I’d certainly recommend Wifite.


Probably one of the more exciting and recent WiFi Hacking Tools that we’ve listed within this resource. This software comes highly recommended.

Airgeddon is a multi-use bash script for Linux systems to audit wireless networks. This tool, like other WiFi hacking software in this resource, can switch your interface mode from “Monitor” to “Managed”.

But, this tool does a whole lot more. For example, a security engineer (Penetration Tester) you can execute a DoS attack over a wireless network using different methods (mdk3, mdk4 and by using another popular Wireless tool called aireplay-ng). The tool is also able to work as a MITM “Evil Twin” Wireless attack.

This tool offers full support for 2.4Ghz and 5Ghz bands and can easily capture WPA/WPA2 personal network handshakes as well as cleaning and optimizing the handshake captured files.

What makes this tool different is that it can decrypt offline passwords that have been captured and then they can be brute-forced.

This is an excellent tool and one we’d certainly recommend you get to learn.


Wifiphisher is a WiFi hacking tool that can execute speedy automated phishing attacks against Wireless/WiFi networks with the intention of discovering user and password credentials The difference with this wireless tool (compared with the others) is that it launches a Social Engineering attack which is a completely different attack vector to take when attempting to breach WiFi networks.

Is Wifiphisher free?

Yes. This WiFi ‘cracking tool’, as it is often referred to – is completely free and available from GitHub.

Does Wifiphisher work on all Operating Systems, and what are the requirements?

  1. Kali Linux is the officially supported Linux distro, but according to the developers GitHub page some users have been able to get the framework to work on other platforms. To be safe though we’d always recommend trying it either on Kali and almost certainly Linux since that is where you’ll get the most support.
  2. You’ll also need a wireless network adapter that supports ‘Access Point’ (AP) mode, and your driver should also support Netlink.
  3. Wireless network adapters are required that can be placed in ‘Monitor Mode’ and that are able to perform injection attacks.

What are the Typical Uses for Wifiphisher?

Wifiphisher can be used to a crack WiFi password. This tool takes the following steps: Wifiphisher deauthenticates the user from their legitimate AP. The framework then allows the user to authenticate to the Evil Twin AP that must be set up for the attack to be successful. Wifiphisher will then offer an HTML webpage to the user on a proxy that will notify them that an upgrade on the firmware has taken place and will ask them to authenticate again. The wifi password is passed to the hacker while the user will continue browsing the web not knowing what happened.

How To Install Wifiphisher

This WiFi hacking tool should ship with Kali Linux, but if it doesn’t then you will need to take the following steps to install the software:

Fern WiFi Wireless Cracker

Fern Wifi Cracker is a Wireless attack software and security auditing tool that is written using the Python Qt GUI library and Python Programming Language. This tool can recover and crack WPA/WEP/WPS keys and can run other network-based attacked on ethernet or wireless-based networks.

Is Fern WiFi Wireless Cracker Free?

Yes Fern Wifi Cracker is free of charge.

Does Fern WiFi Wireless Cracker Work on all Operating Systems?

This works on Kali Linux operating systems.

What are the Typical Uses for Fern WiFi Wireless Cracker?

This tool helps in assisting with Network security by enabling the user to view and discover network traffic in real-time and therefore can identify the hosts and network data discovery. With the network server data features, it will help toughen your server and discover vulnerabilities before they are exploited.


inSSIDer is a Wi-Fi network scanner app for Microsoft Windows and OS X which has won a ton of awards. This tool has won many awards such as a 2008 Infoworld Bossie Award for “Best of Open Source Software in Networking”, but as of inSSIDer 3, it is no longer open-source. This tool has rave reviews when working alongside other wireless hacking tools.


KisMAC is a wireless network discovery tool for Mac OS X which is the mac version of Kismet. Although not as novice-friendly as similar applications this WiFi Hacking tool has a very popular following.


Kismet is a wireless network detector, packet sniffer, and intrusion detection system for 802.11 wireless LANs and other technologies. Kismet will work with any wireless card which supports raw monitoring mode and is able to sniff the packets on 802.11a, 802.11b, 802.11g, and 802.11n traffic. The program runs under Linux, FreeBSD, NetBSD, OpenBSD, and Mac OS X.

Popular WiFi Hacking FAQ

How Can I Hack WiFi Using My Android?

It is possible and of course, it totally depends on what WiFi technology you are trying to exploit. A simple way is to download and install the “WPA WPS Connect App” from the Google Play Store. Open the app and hit the “scan” button to start WiFi scanning. When you find a network you may find a bunch of networks that are vulnerable to the WPS vulnerability (the app uses a bunch of PIN codes according to the type of WiFi router).

What Android App Is Best For Hacking WiFi Network?

As mentioned in my Concise Courses Mobile Hacking FAQ, the most popular or best known for Penetration Testers is the “WPA WPS Tester Android App” which was developed with the purpose of being able to scan WiFi networks for vulnerabilities.

Is It Against The Law To Hack A WiFi Signal Or Network?

The instant and easy answer to this question are: yes it is illegal! 

The law will always view this as illegal. Always seek permission from the SysAdmin or owner of the network of course.

Penetration Testers hack into a WiFi network through a bunch of different ways, with the most popular being brute-force attacks.
