Network Hacking

Despite the hackers, there are “occasional” hackers who are using the network hacking to crack wireless passwords because internet connections are a necessity in our lives but how is a wireless network secured? In case of secured wireless connections, encrypted packets represent internet data under another form.

Packets are encrypted with network security keys and basically if you want to have access to internet wireless connection then you should have the security key for that particular wireless connection. There are two types of encryptions in use WEP (Wired Equivalent Privacy) and WPA (Wi-Fi Protected Access), WEP is the fundamental encryption and a very small number of people use it because it’s very unsafe and it can be cracked very easy. WPA is the more secure option, WPA-2 is
the most secure encryption of all time and you can crack a Wi-Fi Protected Access network then you will need a wordlist with common passwords but it can be unbreakable if the administrator is using a complex password and because a lot of people are interested in breaking Wi-Fi protected connections, this book is going to show you how to do it. You will need a compatible wireless adapter, CommView for Wi-Fi, Aircrack-ng GUI and a big bag full of patience. This operation is
impossible without a compatible wireless adapter, your wireless card must be compatible with the software CommView, software used for capturing the packets from the network adapter, and you can download the software from their website.

Aircrack-ng GUI is practically doing the crack after capturing the packets. Don’t forget two main things before starting: select the network with the highest signal and remember that every network has its details in the right column, not in the left column. Set up CommView and choose your target network, select it and double click on “capture” with CommView and the software will start collecting  packets from the selected channel. If you want to capture packets only from the target network then right click on the target network and copy the MAC address, on the top change to Rules tab, on the left pick MAC addresses and enable them. Once you have done this, select the option capture and for ‘add record’ please select both and paste the copied addresses in the displayed box. Enable auto saving in the logging tab, set MDS (Maximum Directory Size) to 2000 and ALFS
(Average Log File Size) to 20. And you are at the point where you should use your patience and wait until at least 100,000 packets are captured and export them by going in the log tab and selecting concatenate logs and select everything that has been saved and don’t forget to keep CommView open, take a walk to the folder where you have saved the concatenated logs and open it and click on File- Export - Wire shark tcpdump format and chose any destination, after doing this logs will
be saved with .cap extension. Next, open Aircrack-ng and there you will find a zip file, extract it and open it and navigate to ‘bin’, now run the software and choose WEP. Remember the file you saved earlier .cap? Click ‘launch’ and in the command prompt write the parameter number of your desired network and wait for a few seconds. Enjoy the internet now!
