Introduction
I was recently presented with a packet capture file to perform some forensics on it as a challenge and see if I could find the hidden message. Naturally, it being a packet capture I fired up Wireshark only to be faced with a very bland single colour screen, quite different from the usual network captures most would be used to when using Wireshark (see Figure 1 below). There was none of the usual indication of different protocols broken down by colour. This was going to be a different type of challenge, and one I was going to learn a lot from, I knew I would enjoy it, and I sure did!
