You don’t have to undergo special training or be an IT expert to hack Wi-Fi security key. Instead you only have to comprehend the sequence of procedures and some knowledge about the key aspects and terminologies.
A protected wireless connection sends data as encrypted packages which contain network security keys.
WEP is the basic and standard form of encrypted data and WPA is the most difficult to crack and therefore, safest. WPA standard has a second version as well called WPA2. Out of these three WPA2 is most reliable and secure while WEP is the least secure.
For hacking a network’s security code, hackers usually find WEP easier because WPA hacking entails complicated programming and requires sophisticated material for hacking. WEP based networks are highly vulnerable whereas WPA can only be cracked through a brute-force attack.
You will need a compatible wireless adapter, which actually is the most important requirement. If your computer’s wireless card is not compatible the hacking effort will be fruitless. Similarly it is recommended download and install Wi-Fi password unlocking software called unlockers such as CommView. This will help you recognize a vulnerable wireless network for hacking. Unlockers capture the encrypted data packets and different software is used for performing actual cracking. For cracking you must download some reliable cracker software such as Aircrack-ng GUI.
The First step is to target a WEP encrypted network. This is done through spying which in hackers’ fraternity is called Sniffing. To perform sniffing, you have to survey the traffic after activating the password unlocker software. Once you choose simply click the Capture Tab. The software will automatically start capturing the encrypted data packets. A minimum of 100,00 data packets will be required if you want to capture decent Wi-Fi signals. After capturing export these packets to your computer while the unlocker software is enabled and save these packets in a folder after choosing an appropriate destination.
After capturing you need to crack the data packets so install and load the software and select WEP. Launch the previously saved data packets and enter the index number of your selected wireless network. Shortly after this you will be prompted with the security key. However, if the software gives the error of insufficient packets then you will have to capture more data packets. This is a time consuming task but very exciting as well.
Hackers often use a wordlist or dictionary comprising of common passwords for retrieving WiFi network passwords/security key. A hacker’s dictionary is a program which works on trial and error method. You will have to match every keyword/passphrase of the dictionary with the security code of your chosen network until your retrieve the exact password.
There is another method for accessing the security key of a WiFi network called Brute-force. In this kind of attack hacker has to try out all probably character combinations. If the password’s character list if more than eight then almost a week will be required to check all the combinations.
To perform unlocking through USB, you will require a bootable USB pen drive and appropriate software. If the USB drive is not bootable then download UNetbootin software to make it bootable. Now start your PC and boot from USB drive and run the unlocking software. It will start scanning your locality for vulnerable networks. Remember that you can only hack the network which has a client. Select a network of your choice from the retrieved list and click on Dictionary-Launch-attack for initiating the cracking procedure. The password will be automatically retrieved.
