What do you do if a hacker takes control of your ship? (2023)

Pop‑culture framing and tone

• Many comments riff on movies and TV (e.g., “Hackers”, “Battlestar Galactica”, “The Italian Job”, “Red Dwarf”) to illustrate cyber‑hijacking, air‑gapped ships, and “toaster”/robot threats.
• Humor is used to cope with the seriousness of cyber‑physical risks.

Drive‑by‑wire vehicles and broader cyber‑physical risk

• Several commenters see ship hacking as a warning for internet‑connected, drive‑by‑wire cars.
• Concerns:
  • Remote control of steering/brakes/engine for mass casualties, extortion, or covert assassinations.
  • Nation‑state use in a Taiwan/US conflict; terrorism; stock manipulation.
• Others argue:
  • Coordinated “all at once” attacks may be less tactically useful than long‑term subtle manipulation.
  • Old analog or early‑ECU cars are perceived as safer and easier to maintain but still hackable with local access.
  • Modern driver‑assist actuators are often torque‑limited, making full remote steering harder, though exceptions (e.g., full steer‑by‑wire) exist.

Manual control vs automation on ships

• Some advocate non‑networked backup GPS/radar and ways to manually control engines and rudder, plus regular drills.
• Others counter that “manual” control of giant rudders/engines is unrealistic; systems are huge, tightly integrated, and historically needed extensive automation.
• Clarifications:
  • Large ships often have emergency hydraulic steering in a dedicated compartment, with commands relayed by phone/radio.
  • Debate over regulations and whether redundant power units/circuits actually mitigate a cyber‑compromised control system.
  • “Manual” is interpreted as bypassing smart systems via simpler, local controls, not literally pushing the rudder.

Network architecture and industrial control security

• Proposed mitigations:
  • Separate operational ship systems from networked/IT systems with physically severable bridges.
  • Minimize or eliminate permanent writable memory on the “secure” side; boot from ROM, refuse remote updates.
  • Defense‑in‑depth, zero‑trust isolation, and strong change‑logging for critical software.
• Counterpoints:
  • Technicians can inadvertently re‑bridge networks (e.g., through laptops or ad‑hoc wireless links).
  • PLCs and general‑purpose controllers are extremely flexible but also highly hackable.
  • True air‑gapping and robust SCADA separation are expensive and operationally painful, especially for updates.

Baltimore bridge collision and real‑world scenarios

• Question raised whether the Baltimore bridge incident was a cyberattack; consensus in the thread is “no,” but its scale illustrates what a malicious event could look like.
• Discussion of whether manual/emergency steering could realistically have prevented that collision is inconclusive and seen as context‑dependent.

Motivations and threat models

• Suggested attacker types:
  • Nation‑states seeking economic and infrastructure disruption.
  • Terrorists aiming for high‑casualty or spectacular attacks.
  • Extortionists and ransomware groups preferring assets to remain usable.
  • Individuals “who just want to see the world burn” or unsophisticated actors.
• Some note that simple physical sabotage (e.g., blocking bridges with cars) might be easier than complex cyber‑scenarios.

Training, preparedness, and practical mitigations

• Thread notes a gap between highly technical threats and low‑technical crews; skepticism about the value of generic “don’t click phishing links” training on ships.
• Suggestions:
  • Ship‑specific incident playbooks, intensive simulations, and red‑/blue‑team exercises involving captains and pilots.
  • Rapid response/SOC for ships, treating serious compromise as an immediate emergency (EPO/Mayday).

Skepticism and risk perception

• Some commenters downplay ship‑hijack risk:
  • Few people live near coastlines, and ships can’t hit inland targets like the Pentagon.
  • Ransomware actors usually avoid destroying assets.
• Others counter:
  • Economic damage to ports, canals, and trade routes can be strategically devastating.
  • Past non‑cyber disruptions of major chokepoints show how “mostly economic” damage can have huge global impact.
• Several call for stronger one‑way data flows (e.g., data diodes) to allow monitoring without exposing control channels, though detailed feasibility is not resolved.
