Capture Wi-Fi Traffic (Facebook)

[DanielPatrick]

Is it possible to capture Wi-Fi traffic, more specific Facebook traffic? I am working on a dissertation and doing some tests. I know that there are some tools such as FireSheep, WireShark and there might have been another one, but could they really work since most traffic is now passed over HTTPS rather than the old HTTP protocol. Please consider that I have access to this Wi-Fi point as it is mine.

Is there a way?

Sure you can capture WiFi traffic, as long as you are in range of the client and/or on the same WiFi network. The question is can you decipher the data. As you said, it's using SSL encryption, so you won't see clear text data going over the air. If you have access to the back end of the network, you can use deep packet inspection on your firewall to determine the destination of those encrypted packets, but you aren't going to be able to see things like passwords, what gets posted or shared, etc.
