Porting AirPCap to C#

As part of my security work I often perform wireless audits of 802.11a/b/g/n networks and use a variety of tools to manage this. A couple of weeks ago I finally got myself a CACE Technologies Airpcap NX device. It's a small USB wireless adaptor with two external antenna connections. The NX model supports packet transmission or injection also.

I've written a few custom tools before using the SharpPcap library for DotNet and figured I would do a couple more to utilise the enhanced capabilities of the new hardware. Out of the box it works a treat, and is visible to SharpPcap (and any other winpcap applications I suspect), however the airpcap specific features are not exposed through these apps. The only applications which support the full functionality of the device are some custom versions of aircrack and kismet which use cygwin to run on windows.

So, this brings me to my first opensource project. I've decided I should extend the functionality of SharpPcap to support an additional device type and expose the full capabilities of the airpcap hardware.

More details to come...
