Download the necessary programs. You will need 2 programs to make this hack work: CommView (which will be used to look for vulnerabilities in the network you’re trying to access[4]) and AirCrackNG (which will break the security key itself)- Make sure your computer’s wireless adaptor is compatible with CommView.
2
Find a Network. Use CommView to scan for wireless networks. Choose a network with a WEP key and a decent signal.
3
Filter the search to that network. Right click on the network you want to access, select “Copy MAC address”, go to the Rules tab, then MAC Addresses, enable MAC address rules, then click Action→Capture→Add Record→Both. Paste in the MAC address.
4
View Data packets. Sort out the Management (M) and Control (C ) packets so that you are only viewing the Data (D) packets.
5
Save the packets. Go to the Logging tab and enable auto saving. You may need to change the settings on the Directory size and File size. Try 2000 and 20, respectively.
6
Press the “Play” button to begin collecting. Wait until you have at least 100,000 packets.
7
Click “Concatenate Logs” under the Log tab. Make sure all of the logs are selected.
8
Export the logs. Go to the folder where the logs were saved and open the log file. Click File→Export→WireShark/tcpdump format and save it where you can find it easily.
9
Open the newly created file with Aircrack. Start Aircrack and choose WEP. Open the file and click “Launch”.
10
Enter the index number. When the command prompt opens, you’ll need to enter the index number for the target network. It is probably 1. Hit enter and wait. If it works, the key will be shown.
