In 1995, when the fictitious Dade Murphy and his friends stopped oil tankers from being capsized by a virus in the movie “Hackers”, “digital piracy” was just a euphemism for copyright infringement and sharing music. Today digital piracy is anything but a euphemism or fiction. From breaches by pirates seeking cargo information, to denial of service (DOS) attacks on offshore oil platforms, there are very real threats to the maritime sector. This talk will provide an introduction to understanding ships as Industrial Control Systems (ICS) and lessons learned from vulnerability research on marine diesel engine controllers. We also hope to challenge our peers in the infosec community to apply their skills, red and blue, to protect our maritime critical infrastructure. A talk for anyone who likes computers and pirates. Arrgh!
