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. Sadly 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.
Cracking those Wi-Fi passwords is your answer to temporary internet access. This is a comprehensive guide which will teach even complete beginners how to crack WEP encrypted networks, easily.
In a secured wireless connection, internet data is sent in the form of encrypted packets. These packets are encrypted with network security keys. If you somehow manage to get hold of the key for a particular wireless network you virtually have access to the wireless internet connection.
Broadly speaking, there are two main types of encryptions used.
This is the most basic form of encryption. This has become an unsafe option as it is vulnerable and can be cracked with relative ease. Although this is the case many people still use this encryption.
This is the more secure alternative. Efficient cracking of the passphrase of such a network requires the use of a wordlist with the common passwords. In other words you use the old-fashioned method of trial and error to gain access. Variations include WPA-2 which is the most secure encryption alternative till date. Although this can also be cracked using a wordlist if the password is common, this is virtually uncrackable with a strong password. That is, unless the WPA PIN is still enabled (as is the default on many routers).
Hacking WEP passwords is relatively fast, so we'll focus on how to crack them for this guide. If the only networks around you use WPA passwords, you'll want to follow this guide on how to crack WPA Wi-Fi passwords instead.
This is by far the biggest requirement.The wireless card of your computer has to be compatible with the software CommVIew. This ensures that the wireless card can go into monitor mode which is essential for capturing packets. Click here to check if your wireless card is compatible
This software will be used to capture the packets from the desired network adapter. Click here to download the software from their website.
After capturing the packets this software does the actual cracking. Click here to download the software from their website.
Start scanning for wireless networks.
CommView now starts scanning for wireless networks channel by channel. After a few minutes you will have a long list of wireless networks with their security type and signal. Now it is time to choose your target network.
A few things to keep in mind before choosing the target wireless network:
Once you have chosen your target network, select it and click Capture to start capturing packets from the desired channel.
Now you might notice that packets are being captured from all the networks in the particular channel. To capture packets only from the desired network follow the given steps.
We need to capture only data packets for cracking. So, select D on the bar at the top of the window and deselect M (Management packets) and C (Control packets).
Now you have to save the packets so that they can be cracked later. To do this:
Now the boring part- WAITING!
NOTE: The amount of time taken to capture enough data packets depends on the signal and the networks usage. The minimum number of packets you should capture should be 100,000 for a decent signal.
After you think you have enough packets (at least 100,000 packets), you'll need to export them.
You may also receive a request to try with more packets. In this case wait until more packets have been captured and repeat the steps to be performed after capturing packets.
BEST OF LUCK!
