Suggested- Best Hacking Tools For Windows 10. In this article, we provide a list of top 10 Wi-Fi hacking tools that can crack the networks to get access.

Hacking and its consequences: – Hacking is frowned upon and illegal in almost all the countries across the globe and should not be done for illegal purposes.

Note: This article is for educational purposes only and should be used to find and fix vulnerabilities in your own network. Under no circumstances, should you use these programs to gain illegal access to other wireless networks.

Hacking Wifi

Hacking anything starts with the simple process of finding vulnerabilities and then using them to gain access. Similarly, there are many types of vulnerabilities that you can find among Wifi protocols.

-> Poor Configuration

These are lapses and loopholes in the configuration of any wireless network. Any wireless network, when beinG setup, has its own default values and settings to ensure easy setup. Often users that are not familiar with this aspect tend to keep the same default values/settings, without any knowledge about it. This becomes a free gateway for any kind of attack as these default values are often known by attackers, or if not known, then are easily available by monitoring the network.

– > Poor Encryption

These are security lapses, and loopholes in the encryption of your passwords or data.


These can be because of the poor choice of passwords or simply because of the use of a weak security protocol. Weak security protocols are like invitations to wireless attacks and hence should be maintained regularly.

Wifi Security Protocols

– WEP and WPA

WEP stands for = Wired Equivalent Privacy

WPA stands for = Wi-fi Protected Access

WEP is an obsolete Wi-fi Lan security protocol, used back in the 1990s during the onset of Wireless technology. The protocol was found to be seriously vulnerable and weak. Soon hackers and other malicious users were able to take advantage of this and carry out unethical tasks. Hence soon WPA protocols were introduced in the beginning of 2000s to provide users with more protection when compared to the WEP protocol. This new protocol was available in two different versions, WPA 1 and 2. These protocols are the current security protocols used in wireless machines today, to ensure proper security of your network.

Hence To gain access to any Wifi network, you would either have to bypass WEP or WPA protocol, depending on the one that is active. To bypass or crack the security protocols you can either take advantage of WEP weakness or continuously attack WPA1 or WPA2 to ultimately gain access to the wi-fi network.

You can also use key loggers and other monitoring tools to gain access to the network, if you are unable to crack the WEP/WPA security protocols.

Below is the list of programs you can use to find vulnerabilities in your wireless network and gain unauthorized access.

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 How to Hack WiFi 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

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 WiFI (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.

  • WebDecrypt– this WiFi password hack tool uses active dictionary attacks to crack the WEP keys. It has its own key generator and implements packet filters for hacking WiFi password. http://wepdecrypt.sourceforge.net/

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 WiFi hacker online tools can be used to crack WPA keys.

  • CowPatty– this WiFi password cracker tool is used to crack pre-shared keys (PSK) using brute force attack. http://wirelessdefence.org/Contents/coWPAttyMain.htm
  • Cain & Abel– this WiFi hacker for PC 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. https://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 WiFi password hacking 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.
