Hacking US (and UK, Australia, France, etc.) traffic control systems
Cesar Cerrudo CTO, IOACTIVE LABS
Probably many of us have seen that scene from "Live Free or Die Hard" (Die Hard 4) were the "terrorist hackers" manipulate traffic signals by just hitting Enter key or typing a few keys, I wanted to do that! so I started to look around and of course I couldn't get to do the same, that's too Hollywood style! but I got pretty close. I found some interesting devices used by traffic control systems on important cities such as Washington DC, Seattle, New York, San Francisco, Los Angeles, etc. and I could hack them :) I also found that these devices are also used in cities from UK, France, Australia, China, etc. making them even more interesting. This presentation will tell the whole story from how the devices were acquired, the research, on site testing demos (at Seattle, New York and Washington DC), vulnerabilities found and how they can be exploited, and finally some possible NSA style attacks (or should I say cyberwar style attacks?) Oh, I almost forgot, after this presentation anyone will be able to hack these devices and mess traffic control systems since there is no patch available (sorry didn't want to say 0day ;)) I hope that after this I still be allowed to enter (or leave?) the US
