If you’ve ever read a story about Defcon, the lede probably had something to do with The Wall of Sheep, the giant pojection of every plaintext username and password crossing the network. You may have even seen one of your favorite sites fall victim to it. One of my favorite people, Irongeek, decided to whip up a little PHP script so that anybody could set up their own Wall of Sheep style system. The backend is powered by the near-magical Ettercap and the script just parses the output into an easy to read format. I think this would be a great warning sign to place on your hotspot’s splash page.
