Open IP ports let anyone track ships on Internet

While digging through the data unearthed in an unprecedented census of nearly the entire Internet, Researchers at Rapid7 Labs have discovered a lot of things they didn’t expect to find openly responding to port scans. One of the biggest surprises they discovered was the availability of data that allowed them to track the movements of more than 34,000 ships at sea. The data can pinpoint ships down to their precise geographic location through Automated Identification System receivers connected to the Internet.
