The wireless LAN or wifi provides us an alternative way to connect to the Internet provided that your wireless device is in range of a wireless network. More people are utilizing this method to connect to the Internet since it is really easy to use. Wifi is so popular that not only Starbucks but coffee shops are providing wifi for their customer to use. But what most people are not aware of is the security wifi provides that would cause harm to their devices connected to the wifi or worst get charged for network criminal activities.
That is why it is important to encrypt their wireless routers with passwords. There are some wireless encryption standards that can be used which are WEP, WPA, WPA2. WEP has been shown to be easily breakable when correctly configured. WPA and WPA2 are much more stronger encryption than WEP. Most people would use WEP since most wireless routers default password encryption is WEP and they probably wouldn’t know the difference between those encryption standards anyway. WEP is so easy to break that some are using their neighbors wifi to connect to the Internet.
I wanted to know how to break the WEP encryption to see how easy it was. So I started googleing and I found that I don’t need to write actual codes to break it. There are programs on the Internet that helps you to do this. One that works is Aircrack-ng. It can be done on most operating systems but it works better on a Linux distribution. Here are few of the links that are useful:
I’m not encouraging to break into someone wifi and use their Internet access. Let’s put it this way, I want the world to know that WEP is not secure. So use WPA2 instead :)
(In the end I did not managed to crack the WEP encryption because my wireless adapter is Intel)
