Anyone who is inside the wireless network's transmission radius has access to it.
Thus they are prone to attacks. In areas such as airports, restaurants, etc hotspots are available. Here we will tell you about the common techniques that can be used to exploit weaknesses in the security implementations of WiFi networks. Also, we will talk about some measures to counter these breaches of WiFi access and protect your network from attacks.
How to Crack WiFI (Wireless) Networks
To access a wireless network, you will need a wireless network-enabled device like a laptop, tablet, smartphone, etc. Also, you need to stay within the radius of transmission or range of the wireless network access point.
If the WiFi option is turned on, most devices will give you the list of the available networks.
The networks which are not protected by a password can be accessed just by clicking. If the network has a password, then you have to find the password to access it. You can exploit the weaknesses in wireless networks and gain unallowed access to the network.
This is called cracking. WEP cracking is the exploitation of the WEP networks to implement security controls. Cracking wireless networks can be done, majorly, in two ways:. Passive cracking– This is quite difficult to detect.
It has no effect on the traffic of the network til the WEP security has been cracked. Active cracking– This increases the load on the traffic. Compared to passive cracking, this can be easily detected. It is also more effective than passive cracking.
How to Hack WiFi Password
Aircrack– This is a network sniffer and a WEP cracker. WEPCrack– This here is an open-source( unpaid ) WEP hacker who cracks the 802.11 WEP secret keys.

- FMS attack is implemented through this. Kismet- It detects the wireless networks which are visible as well as the hidden, sniffer packets and also detects intrusions.
- WebDecrypt– It uses active dictionary attacks to break the WEP keys. It has key generators of its own and it implements packet filters for hacking WiFi passwords.
- For authentications, WPA uses a 256 pre-shared key or passphrase. Mostly, if short passphrases are used, they become vulnerable to dictionary attacks.
- The mentioned Wifi hacker tools can be used to crack the WPA keys. CowPatty– This tool is mainly used while cracking pre-shared keys (PSK) using force.
Cracking Wireless network WEP/WPA keys
Cain & Abel– This tool is used to decode the capture files from different sniffing programs like Wireshark. The files that are captured might contain WEP or WPA-PSK encoded frames. Sniffing– Sniffing involves the intercepting of packets as they are transmitted over a network.
Then the captured data is decoded using tools such as Cain and Abel. Man in the Middle (MITM) Attack– In this, you basically eavesdrop on a network and absorb all the sensitive information. Denial of Service Attack– This attack is mainly to deny the legitimate users, network resources.
This type of attack can be performed using FataJack. Cracking Wireless network WEP/WPA keys.
You can crack the WEP/WPA keys and get access to the Wifi network. All you need are the hardware and software resources and some patience.
These attacks also depend on the activity of the users of the network to be cracked.
How to access a wireless network?
Backtrack is an operating system that is Linux-based and developed on top of Ubuntu. It comes with a number of security tools and can be used to gather information, trace the vulnerabilities and then exploit the network.
