A detailed view of wireless network and how to hack Wi-Fi

- Advertisement -

The wireless network is a type of network where radio waves are used to link computers, phones, and other devices together. This implementation is processed at the physical layer or layer 1 of the OSI model. Wireless networks can be accessed by anyone who is in the range of transmission radius of the router and this makes them get attacked vulnerably and also it becomes easy as there are many links that teach you how to hack Wi-Fi. Hotspots are available in many public places like parks, restaurants, airports, and so on.

For accessing the wireless networks, you need a device that is enabled for the wireless network such as smartphones, laptops, tablets, or some other device. You also have to be within the range of transmission radius access point of a wireless network and if the option of the wireless network is turned on, most of the devices will show you the list of available networks. If the wireless network is not protected by the password, then you can access it by just clicking on the connect option and if the wireless network is protected by the password, then you need the password for accessing it.

how to hack Wi-Fi

A wireless network can be easily accessed by everyone through using a device and it is enabled for the wireless networks. Many wireless networks will be protected by the password and you can get the password from the administer for access to the wireless networks. The following are some of the commonly used authentication techniques for WEP and WPA.

Wired equivalent privacy is abbreviated as WEP and it was created for IEEE 802.11 OF WLAN standards. The goal of WEP is to provide privacy that is equivalent to the privacy provided by the wired networks. Wired equivalent privacy is worked by encrypting the data that is transmitted through the network for keeping them safe from eavesdropping.

Authentication of the wired equivalent privacy is the open system authentication that is abbreviated as OSA and shared key authentication that is abbreviated as SKA. The open system authentication method grants access for the station authentication requested that is based on the policy of the configured access. The shared key authentication method was sent to an encrypted challenge of the station requesting access and the station will encrypt the challenge by using its key and then it will respond. If the encrypted challenge was matched to the AP value, then the access will be granted.

The wired equivalent privacy has some significant design vulnerabilities and flaws that provide a way for hack and they are as follows: The packet’s integrity will be checked by using CRC32 which is the acronym of cyclic redundancy check and this CRC32 integrity check will be compromised by capturing of minimum 2 packets. The bits in the checksum and the encrypted stream can be altered by the attracter and the authentication system accepts the packet and which leads way to the network’s unauthorized access.

For creating stream ciphers, wired equivalent privacy uses the encryption algorithm RC4. The input of the stream cipher is made of a secret key and an initial value Where is the initial is abbreviated as IV and its length is 24 bits long whereas the length of the secret key may be either 104 bits long or 40 bits long. The total length of both the secret key and the initial value may be either 128 bits long or 64 bits long. The possible lower value of the secret key will make it easy to crack.

Weak initial value combinations are not encrypted sufficiently and this makes to attack vulnerably. The implementation of the key management is poor so that the especially on large networks, changing keys are challenging as WEP does not have a key management system that is centralized and the initial value are reused in wired equivalent privacy.

As WEP has the above security flaws, the next generation is WPA.

Wi-Fi protected access is abbreviated as WPA which is a security protocol that was created by the Wi-Fi Alliance for the response to the flaws found in wired equivalent privacy. It is used for encrypting data on 802.11 WLANs and it uses a higher IV that is the higher initial value of 48 bits instead of the lower initial value of bits that are used by wired equivalent privacy. For encrypting the packets, Wi-Fi protected access uses the temporal keys.

Wi-Fi protected access has the following weakness that leads to Wi-Fi hack, the implementation of the collision avoidance can be broken, the denial of service attacks will be vulnerable, passphrases are used by pre-shares and to dictionary attacks weak passphrases are vulnerable.

How to hack Wi-Fi of wired equivalent privacy, Wi-Fi protected access, and the tools used for cracking WEP and WPA

Cracking is a method of utilizing security weakness in wireless networks and the process of gaining unauthorized access. Wired equivalent privacy cracking refers to utilize the networks that used wires equivalent privacy for implementing security controls. There are commonly two types of cracking in wired equivalent privacy such as passive cracking and active cracking.

Passive cracking is the type of cracking that has no result on the network traffic up to the WEP security was cracked and also it is very hard to detect. Dynamic cracking is a kind of attack or cracking that has a high load result on the network movement. It is very simple to detect when compared with passive cracking and also it is more effective when compared with passive cracking.

There are 4 commonly used cracking tools available for cracking wired equivalent privacy and they are as follows, WebDecrypt, kismet, WEPCrack, and Aircrack where Aircrack is the wired equivalent privacy and network sniffer, WEPCrack was an open-source program that is used for breaking secret keys of 802.11 WEP, Kismet is a cracker that includes detecting intrusions, sniffer packets, detector wireless networks of both hidden and visible and WebDecrypt is a tool that is used for active dictionary attraction for cracking the wired equivalent privacy keys. These tools implement the packet filters and use their own key generator.

Wi-Fi protected access is using 256 pre-shared passphrases or keys for authentications and here the short passphrases are vulnerable or the dictionary attacks and other attacks are used for cracking passwords. The following are the tools that are used for cracking the keys of Wi-Fi protected access CowPatty and Cain & Abel.

CowPatty is a tracking tool that is used for cracking pre-shared keys which we abbreviated as PSK and this is used for brute force attack. Cain & Abel is a cracking tool that is used for decoding capture files from some other sniffing program like Wireshark and these capture files may contain Wi-Fi protected access or wired equivalent privacy encoded frames.

The following are the general types of attacks that give a key for Wi-Fi hack such as a denial of service attack, MITM attack that is Man in the middle and sniffing where sniffing is a cracking method that is transmitted over a network as they involve intercepting packets and here then the captured data can be decoded by using the tools which include Cain & Abel.

Man in the middle which is abbreviated as a MITM attack is a cracking method that involves capturing sensitive information and eavesdropping on a network. Denial of service attack is a method of cracking which has the main intent of denying the network resources of the legitimate users and FataJack can be used for performing this type of attack.
