Traffic gods

Some cities (not Buffalo, AFAIK) have devices on their stoplights that allow for emergency vehicles to change them remotely. The trafic signal crack has always been something of a Grail for hackers. Phrack ran an article recently on possible ways to get at a city-wide grid. But what if you could just buy your own remote. Clearly these must have some form of encryption, but just as clearly, this many devices lying around and the necessity to make them easy to use provides an opportunity for intrusion. As is often the case, physical security trumps encryption, especially when it comes to swarming attacks. (via Felton)
