Hacking like in the movies
Probably many of you have watched scenes from "Live Free or Die Hard" (Die Hard 4) where "terrorist hackers" manipulate traffic signals by just hitting Enter or typing a few keys. I wanted to do that! I started to look around, and while I couldn't exactly do the same thing (too Hollywood style!), I got pretty close. I found some interesting devices used by traffic control systems in important US cities, and I could hack them :) These devices are also
used in cities in the UK, France, Australia, China, etc., making them even more interesting.
After getting the devices, it wasn't difficult to find vulnerabilities (actually, it was more difficult to make them work properly, but that's another story).
