I was lucky enough (or unlucky enough) to be given the job of spec’ing these laptops and my hunt was to include a decent GPU for hash cracking. I strived for an ATI chip but with budget in mind and with the… Continue reading
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
The tool we’re going to use here is hashcat. I’ll be testing this using a ATI 6950 2GB GPU running on Kubuntu 64bit using catalyst drivers 12.2. Your mileage might vary depending on what card you’re using. Hashcat (now known as oclhashcat-plus) comes with a few different binaries depending on what architecture you’ll be running it on.
