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?

Yous will need a wireless network enabled device such every bit a laptop, tablet, smartphones, etc. You will also demand to be within the transmission radius of a wireless network admission betoken. Nigh devices (if the wireless network option is turned on) volition provide yous with a list of available networks. If the network is not countersign protected, and so you lot just have to click on connect. If it is password protected, then you volition need the password to gain access.

Wireless Network Authentication

Since the network is easily attainable to everyone with a wireless network enabled device, most networks are password protected. Let'due south look at some of the most ordinarily used authentication techniques.

WEP

WEP is the acronym for Wired Equivalent Privacy. It was adult 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 go along information technology safety from eavesdropping.

WEP Authentication

Open System Authentication (OSA) – this methods grants access to station hallmark 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 and so responds. If the encrypted challenge matches the AP value, and then access is granted.

WEP Weakness

WEP has pregnant design flaws and vulnerabilities.

• The integrity of the packets is checked using Cyclic Back-up Bank check (CRC32). CRC32 integrity check can be compromised by capturing at least ii packets. The bits in the encrypted stream and the checksum can exist modified past the attacker so that the packet is accepted past the authentication organisation. This leads to unauthorized access to the network.
• WEP uses the RC4 encryption algorithm to create stream ciphers. The stream cipher input is fabricated upwardly of an initial value (Four) and a secret primal. The length of the initial value (Iv) is 24 $.25 long while the underground key can either be twoscore bits or 104 bits long. The total length of both the initial value and clandestine can either be 64 bits or 128 $.25 long.The lower possible value of the secret fundamental makes it easy to fissure information technology.
• 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 non provide a centralized key management system.
• The Initial values can be reused

Considering 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 constitute in WEP. It is used to encrypt data on 802.11 WLANs. It uses higher Initial Values 48 $.25 instead of the 24 bits that WEP uses. It uses temporal keys to encrypt packets.

WPA Weaknesses

• The standoff avoidance implementation can exist broken
• It is vulnerable to deprival of service attacks
• Pre-shares keys use passphrases. Weak passphrases are vulnerable to dictionary attacks.

How to Scissure WiFI (Wireless) Networks

WEP cracking

Dandy is the procedure of exploiting security weaknesses in wireless networks and gaining unauthorized access. WEP smashing refers to exploits on networks that use WEP to implement security controls. There are basically 2 types of cracks namely;

• Passive cracking– this type of cracking has no outcome on the network traffic until the WEP security has been cracked. Information technology is hard to notice.
• Agile cracking– this type of set on has an increased load consequence on the network traffic. It is easy to detect compared to passive cracking. It is more effective compared to passive swell.

WiFi Password Hacker (WEP Dandy) Tools

• Aircrack– network sniffer and WEP cracker. This WiFi countersign hacker tool can be downloaded from http://www.aircrack-ng.org/
• WEPCrack– this is an open source Wi-Fi hacker program for breaking 802.11 WEP secret keys. This WiFi hacker app for PC is an implementation of the FMS attack. http://wepcrack.sourceforge.internet/
• Kismet– this WiFi password hacker online detects wireless networks both visible and hidden, sniffer packets and observe intrusions. https://www.kismetwireless.net/
• WebDecrypt– this WiFi password hack tool uses active lexicon attacks to fissure the WEP keys. It has its own key generator and implements packet filters for hacking WiFi countersign. http://wepdecrypt.sourceforge.cyberspace/

WPA Bully

WPA uses a 256 pre-shared key or passphrase for authentications. Brusque passphrases are vulnerable to lexicon attacks and other attacks that can be used to scissure passwords. The following WiFi hacker online tools can exist used to crevice WPA keys.

• CowPatty– this WiFi countersign cracker tool is used to crack pre-shared keys (PSK) using fauna force attack. http://wirelessdefence.org/Contents/coWPAttyMain.htm
• Cain & Abel– this WiFi hacker for PC tool tin can be used to decode capture files from other sniffing programs such equally Wireshark. The capture files may contain WEP or WPA-PSK encoded frames. https://www.softpedia.com/get/Security/Decrypting-Decoding/Cain-and-Abel.shtml

Full general Set on types

• Sniffing– this involves intercepting packets every bit they are transmitted over a network. The captured data can so be decoded using tools such as Cain & Abel.
• Human in the Centre (MITM) Assault– this involves eavesdropping on a network and capturing sensitive information.
• Deprival of Service Attack– the chief intent of this attack is to deny legitimate users network resource. FataJack can be used to perform this type of attack. More on this in article

Groovy Wireless network WEP/WPA keys

It is possible to crack the WEP/WPA keys used to gain admission to a wireless network. Doing so requires software and hardware resource, 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.

Nosotros will provide you lot with bones information that tin help you go started. Backtrack is a Linux-based security operating organization. Information technology is developed on summit of Ubuntu. Backtrack comes with a number of security tools. Backtrack can exist used to get together information, assess vulnerabilities and perform exploits among other things.

Some of the popular tools that backtrack has includes;

• Metasploit
• Wireshark
• Aircrack-ng
• NMap

• Kali Operating Organisation. You can download information technology from here https://world wide web.kali.org/downloads/
• Be inside the target network's radius. If the users of the target network are actively using and connecting to it, then your chances of cracking information technology will be significantly improved.
• Sufficient knowledge of Linux based operating systems and working knowledge of Aircrack and its various scripts.
• Patience, dandy the keys may have a bit of sometime depending on a number of factors some of which may be across your command. Factors beyond your control include users of the target network using information technology actively as y'all sniff data packets.

How to Secure wireless networks

In minimizing wireless network attacks; an organisation tin adopt the following policies

• Changing default passwords that come with the hardware
• Enabling the authentication machinery
• Access to the network tin be restricted past allowing only registered MAC addresses.
• Utilise 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 animal force attacks.
• Firewall Software can too assistance reduce unauthorized admission.
