We need to capture the WPA 4 way handshake in order to perform an offline GPU attack. For this demo we’ll be using an Alfa AWUS036H wireless card under Backtrack 5 R2 64bit.

Now I could go in depth about capturing the WPA handshake manually using aircrack-ng but it has been covered in full in many places already, so instead im going to use a great python tool call… Continue reading

I have wrote an automated WEP cracking script ( Let me know if you have any improvements.

Run the following in the first terminal window to create an interface in monitor mode called mon0 of interface wlan0 The second command shows WEP encrypted networks nearby The third command starts capturing traffic from your target
