An internet connection has become a basic necessity in our modern lives. Wireless hotspots (commonly known as Wi-Fi) can be found everywhere!
If you have a PC with a wireless network card, then you must have seen many networks around you. Most of these networks are secured with a network security key.
Have you ever wanted to use one of these networks? You must have desperately wanted to check your mail when you shifted to your new house. The hardest time in your life is when your internet connection is down.
hacking those Wi-Fi passwords is your answer to temporary internet access. In this post i’m sharing easily
hacking methods how to hack any wifi network and also sharing number of security tips to secure our wifi network from hackers.
Must Check : Wi-Fi Password Can Be Hacked with Smart Lightbulb
First we need to scan for available wireless networks.
Theres this great tool for windows to do this.. called
“NetStumbler” or “Kismet” for Windows and Linux and “KisMac” for Mac.
The two most common encryption types are:
1) WEP
2) WAP
WEP i.e Wire Equivalent Privacy is not consideres as safe as WAP
i.e Wireless Application Protocol.WEP have many flaws that allows
a hacker to crack a WEP key easily.. whereas WAP is currently the most secure and best option to secure a wi-fi network..It can’t be easily cracked as WEP because the only way to retreive a
WAP key is to use a brute-force attack or dictionary atack.
Here I’ll tell you how to Crack WEPTo crack WEP we will be using Live Linux distribution called BackTrack to crack WEP. BackTrack have lots of preinstalled softwares for this very purpose.
The tools we will be using on Backtrack are:
Kismet – a wireless network detector
airodump – captures packets from a wireless router
aireplay – forges ARP requests
aircrack – decrypts the WEP keys

Now we need to secure our wifi network from hackers, so i’m sharing most important security tips to secure our wifi network.
How to Secure Wifi Password :-
All of the steps below will require access to the router setup, and we also recommend configuring wireless security over a computer with a wired connection to the router if possible.
1 ) Change default password
Make sure the router password is not still set to the default password. If the password can be guessed this could give someone access to the router setup, which could allow them to change your router settings, including viewing any security keys.
2 ) If available use WPA WPA2, not WEP
Many routers today will offer two different security schemes: WEP and WPA WPA2. We recommend WPA security, since it is more secure than WEP. However, for compatibility with some older devices such as gaming consoles, TiVo, and other network devices may only be able to use WEP, and WEP is better than no security.
3 ) Disable Remote Administration
When enabled, remote administration allows anyone close enough to your router to view or change your router settings. If you never plan on remotely administrating your network, e.g. wireless connecting to the router, we recommend disabling remote administration. With routers that support this option, it is often disabled through the Administration section.
After disabled, the router settings can still be changed using any computer connected to the router using a network cable.
4 ) Change the default SSID name
The SSID is the name that identifies your wireless router. By default, many routers will use the name of the router as the default SSID, for example, Linksys routers use ‘Linksys’ as the SSID. This is a security risk since it identifies the brand of the router and would let any attacker immediately know what exploits to use.
Tip: When naming the router do not use your family or any other identifiable information. For example, if the SSID contains your families last name it can identify by any neighbor.
5 ) Enable router firewall
Many routers also have their own firewall that can be enabled. If available, we also suggest enabling this feature as it helps add an extra layer of security for your network.
6 ) Disable SSID broadcast
To help make finding your wireless network easier wireless routers broadcast your SSID, which means anyone looking for a wireless router could see your SSID. To help make it more difficult for someone to find your network when browsing for a wireless network you can disable the SSID broadcast feature. However, when disabling the SSID broadcast it will require that you manually enter your unique SSID when wanting to connect any new device to your network.
7 ) Enable wireless MAC filter
The Wireless MAC filter feature only allows a wireless device to connect to your router if the MAC Address has been entered into the filter list. This can make connecting new devices to your network more difficult, but improves the overall security of your wireless network.
A quick and easy to set this up is to connect any wireless device you want on your network to your router before enabling wireless MAC filter. After each device has successfully connected, open the DHCP client table, often found in the Status or Local Network section. Each device that has connected to your router thus far is seen and can be copied into a notepad and pasted into the Wireless MAC filter section of the router Security section.
