I think people are having a hard time with the idea that someone could posit that there is a security vulnerability and then actively tamper with the IFE systems while in flight. I know he says he hasn't done that, but I'm not sure I believe that story. If he did in fact try to inject traffic into the network that would affect the flight management computers, then I think he's a fool and a criminal. Highlighting a vulnerability in this fashion is like setting fire to a home to prove it really is flammable. Claiming that you only want to improve fire safety is just a canard. We all know that there are vulnerabilities in every system we use today and it's good for us to RESPONSIBLY work towards improving them. I'm just saddened that this person didn't think anyone was taking him seriously enough that he had to take matters into his own hands.
