With the advent of SDR, such attacks are becoming easier to accomplish and also come into the focus of IT (security) researches. There is already an OSS AIS decoder [1], and I suppose it will not be too hard to make an encoder. Still, we have seen similar attack vectors to GSM (you can DoS a multi-million city with a dozen of manipulated 20$ phones), but no real attacks. Transmitting on licensed frequencies without the proper permission is an offense in most countries, and I suppose you can be liable for the damage, provided the regulation authorities can triangulate you while you are sending out.
