I am preparing for a little presentation on Wifi security / dangers of public networks to a non technical audience and wanted to do a demonstration to make things a little more visual. My idea is to use a tool I had years ago which would look for network packets containing image data and would compile them as they get transmitted. And with this tool active I would ask someone in the audience to navigate to a non https website and then see the images on my PC/projector. It’s a small crowd of elderly people, so the risk of catching something inappropriate should be small. :-)

But, I can’t remember what the tool was called and my search attempts didn’t reveal anything. Anyone got an idea?

Or maybe an idea for an even better demo?

      I herewith grant you the official title of a real hacker :-)

      That’s the tool I was looking for, thanks a lot!

        Turns out there are no more http websites out there, at least I couldn’t find any. Good for our security, bad for my demo :-)

    @thomas I think you’re looking for SNORT, which is a packet sniffer used in intrusion detection. It has been a long time since I used it but I suspect that there are plug-ins that will do exactly what you’re looking for.

      Wireshark is my backup plan for a text based demo. Unless I am missing something pictures in Wireshark will just be binary stuff across multiple packets which won’t work for a demo. The tool I am looking for managed to identify which packets contains image data and showed them in a grid
