You want to learn how to hack wifi password? Hello World, I'm zanidd. Dev, Hobby hacker and PenTesting Intern. And today I'm showing you how to hack a wifi n.
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
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
Ludacris theater of the mind rar. 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
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
- Aircrack– network sniffer and WEP cracker. Can be downloaded from http://www.aircrack-ng.org/
- WEPCrack– this is an open source program for breaking 802.11 WEP secret keys. It is an implementation of the FMS attack. http://wepcrack.sourceforge.net/
- Kismet- this can include detector wireless networks both visible and hidden, sniffer packets and detect intrusions. https://www.kismetwireless.net/
- WebDecrypt– this tool uses active dictionary attacks to crack the WEP keys. It has its own key generator and implements packet filters. http://wepdecrypt.sourceforge.net/
WPA Cracking
WPA uses a 256 pre-shared key or passphrase for authentications. Tomb raider 1 pc download. 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. Shadow blade 1 1 1.
- CowPatty– this tool is used to crack pre-shared keys (PSK) using brute force attack. http://wirelessdefence.org/Contents/coWPAttyMain.htm
- Cain & Abel– this tool can be used to decode capture files from other sniffing programs such as Wireshark. The capture files may contain WEP or WPA-PSK encoded frames. http://www.softpedia.com/get/Security/Decrypting-Decoding/Cain-and-Abel.shtml

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.

- 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.

How to Hack Wifi Password using CMD
The internet over the past few years has become an essential part of the average human. There stands no doubt that the internet has vastly reduced the required efforts we need to put on things by providing help on a number of aspects of life. The internet also helps us in connecting each other via mail, media transactions without having to actually visit the other party at their location.
The help internet connectivity provides us today is insurmountable and cannot be matched by anything else. However, some of us are unable to access the internet at times due to personal network issues and end up looking for free Wi-Fi connections available nearby and in the end, find none. All of this boils to an endless disappointment and boredom. However, after a little bit of research, we have come across some amazing Command Prompt tools which help hack Wi-Fi password using Command Prompt on Windows computers. We will discuss these hacks as we go through the article but first let us know what Command Prompt for Windows is and the network security protocols we can hack through it.
What is Command Prompt?
Command Prompt is an application/tool available on every Windows OS based computer. The tool helps the user interact with their operating system by entering Command Prompt commands to fix various system related issues faced by them.
Even though most of the people find Command Prompt rather useless due to its unattractive user interface and most of its command tasks being available as computer shortcuts now, it is still a very useful tool for Windows computers. Not only does Command Prompt help showing detailed information on computer files and software, it also helps people troubleshoot the problems related to them. Today, network related problems are Command Prompt’s main focus. Various commands like FlushDNS, IPConfig, etc are available for troubleshooting network related problems. Surprisingly, Command Prompt also contains a hidden tool which in generating WiFi password using Command Prompt.
Wi-Fi Network Security Protocols
Although hacking Wi-Fi using Command Prompt is available for all the network types, one must keep the network type of their targeted Wi-Fi network in their minds for an easier hacking experience. So let us learn about these Network types.
Wired Equivalency Privacy (WEP)
The creation of Wired Equivalency Privacy or WEP goes back to the 1990s. WEP came up with the idea of creating a safe platform for internet network user by avoiding hackers from snooping onto internet connections. But after a few years, researchers found out that WEP is rather unsafe to use because various methods had then been available to bypass the security strength of the 90s based network security type. However, WEP is still used in a lot of local Wi-Fi networks today but is the easiest of all network types to hack.
Wi-Fi Protected Access (WPA)
In 2003, an interim security program called the Wi-Fi Protected Access or WPA was released by the Wi-Fi Alliance team. WPA basically was an upgrade to the WEP as it added tighter protocols and more network transaction checks to network connections. It also came up with different security modes for personal and enterprise networks. However, despite the upgrades allotted with the WPA, some hackers could still get into the Wi-Fi networks after a while due to WPS, a feature that came along with the release of the WPA system which enabled an easy connection between network devices. Hence, generating Wi-Fi passwords using Command Prompt on WPA systems is not difficult either.
Wi-Fi Protected Access 2 (WPA2)
WPA was only a year old in 2004 and the Wi-Fi Alliance Team already came up with an upgraded Wi-Fi network protocol called the Wi-Fi Protected Access 2 (WPA2). WPA2 is the latest and the highest Wi-Fi security type available in the market right now, however, after applying the command we found out that it is very easy to hack WiFi password using Command Prompt on WPA2 networks as well.
Now that we have learned about the use of Command Prompt and the different types of Wi-Fi security types available today, let us find out how you can use Command Prompt to hack WiFi passwords on your Windows PC.
- Step 1: Open Run on your Windows computer by searching Run on your Windows Start search bar or by pressing the Windows + R keys together.
- Step 2: Type “cmd” on Run and press the Enter key.
- Step 3: Now, once Command Prompt is open, type the command “netsh wlan show network modes=bssid” on it and press Enter. This should now display the Wi-Fi networks available nearby.
- Step 4: Now, choose the Wi-Fi network you want to hack and remember its name properly.
- Step 5: On CMD, type the command: “netsh wlan connect name=<insert Wi-Fi network name here>”. For example: “netsh wlan connect name=dlink” will hack the Wi-Fi network named dlink
- Step 6: Now, you will be connected to the desired Wi-Fi network. To disconnect, type the command “netsh wlan disconnect” on Command Prompt.
Note: This Command Prompt hack does not work on all Wi-Fi networks especially the ones with high-security strength.
