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.
The AIS receivers, many of them connected directly to the Internet via serial port servers, are carried aboard ships, buoys, and other navigation markers. The devices are installed at Coast Guard and other maritime facilities ashore to prevent collisions at sea within coastal waters and to let agencies to track the comings and goings of international shipping. Rapid7 security researcher Claudio Guarnieri wrote in a blog post on Rapid7's Security Street community site that he, Rapid7 Chief Research Officer H.D. Moore, and fellow researcher Mark Schloesser discovered about 160 AIS receivers still active and responding over the Internet. In 12 hours, the trio was able to log more than two gigabytes of data on ships' positions—including military and law enforcement vessels.
