Daily Blog #39: Web 2.0 Forensic Part 4

Hello Reader,
      I finally got fiddler installed, its windows only and available here http://fiddler2.com/get-fiddler, and it is much improved over the last time I used it! It even has a ajax and xml decoder built in now which is a pretty huge improvement. In this post we are going to focus on what network data is actually being transmitted between the web client and the web 2.0 web application so you can see the raw data that your browser will be parsing and storing in memory/pagefile/hiberfil. Note that if you want to do this time of testing at home you will need a SSL proxy like fiddler in order to capture the traffic, a network sniffer will just see encrypted traffic.

This is what the request for an inbox view looks like in gmail:

Tomorrow let's talk about whats contained in these fields and what a good regular expression to recover the data, heck maybe a foremost rule to automate the recovery for you. Or you can do what I do and get a copy of IEF rather than try to keep up with all the changes that are made to their data formats.
