Hack-A-Ship: Maritime Hacking CTF


Hack-A-Ship is a maritime focused CTF where teams get the opportunity to create cyber effects on real maritime electronics. We utilized Fathom5’s Grace Cyber Testbed to provide a suite of maritime electronics that are fully integrated as they would be on a luxury yacht or small workboat. Teams can earn points for creating effects such as spoofing vessel speed or location on the actual displays that a ship operator would be relying on. We’ve modified the competition to support a virtual competition so teams from anywhere in the world can connect to our testbed and launch their attacks against the system. We start the competition with a NMEA2000 Packet Capture challenge that gets teams familiar with the NMEA2000 protocol and the teams that score the highest on the Packet Capture challenge get first dibs to attack the live maritime electronics.
