Re: AIS "extremely vulnerable to hackers"

Wow, relax guys. Even accounting for the sarcasm you sound a little sensitive about this. You'd think someone called your kid ugly or something.

I don't read it as a reflection on the inherent value of AIS. Every system has room for improvement. All they've done here is identify a behavior of the system that might be a liability under extraordinary circumstances.

The rub will be if they decide to address it, and it results in existing hardware being incompatible with what everyone's already invested in.

The researchers attempted to notify several international marine and communication authorities, but only received a response from the International Telecommunications Union, a United Nations agency that deals with global communications policy. “They seem to be on board with changing the protocol,” says Wilhoit, “but it’s one of those foundational problems that will take time to fix.” AIS equipment has the protocol built in, so rolling out an improved form of AIS requires replacing existing equipment.
