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.
Brute force tools crack Wi-Fi security in hours, millions of wireless routers vulnerable. If you set WPA/WPA2 security protocol on your home or small business wireless router, and you think your Wi-Fi is secure, there two recently released brute force tools that attackers may use to bypass your encryption and burst your security bubble. Overview Wi-Fi Crack allows you to crack any wireless network with WEP security. Powered by AirCrack-NG, the popular, cross-platform, wireless security cracking command-line tool, Wi-Fi Crack you a takes you step-by-step through process of cracking the security of a WEP-based wireless network using a beautiful OS X graphical user interface.
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.
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.
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.
Open System Authentication (OSA) – this methods grants access to station authentication requested based on the configured access policy.
So, that we can play or use Android Apps on our Mac system. Probably Bluestacks is the best Android Emulator for Mac as and are not available for Mac.Bluestacks comes with Google Play Store pre-installed in it, right out of the box. If you ask anyone do you know anything about Android Emulator, that person first may tell about Bluestacks. Bluestacks for MacAs always, Bluestacks is one of the industry leaders in the Android Emulator industry. Because Bluestacks is famous as an Android App Player, Android Game Emulator and Android Developer love this software.
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 has significant design flaws and vulnerabilities.
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.
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;
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.
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;
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)
In minimizing wireless network attacks; an organization can adopt the following policies
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.
