The cyber threat to marine transportation – Canadian Centre for Cyber Security

Summary

The Canadian Centre for Cyber Security assesses the cyber threat environment for Canada’s marine transportation sector (MTS). The report, based on information to 31 August 2024, highlights that financially motivated cybercriminals represent the most likely and immediate threat — with ransomware as the primary disruptive risk. State-sponsored actors (notably from the PRC, Russia and Iran) are actively conducting espionage and pre-positioning for potential disruption, while non-state actors (hacktivists) continue to use DDoS and defacements to cause disruption tied to global events.

The assessment emphasises that digitalisation — increased sensors, connected operational technology (OT), and wider data sharing with third parties — is expanding the sector’s attack surface. Particular vulnerabilities include unencrypted position, navigation and timing (PNT) systems such as GPS and AIS, supply-chain and third-party remote access weaknesses, and Internet-exposed industrial systems.

Key Points

Cybercriminals are the most likely threat to the MTS; ransomware is almost certainly the primary disruptive cyber risk.
State-sponsored actors very likely target the MTS for espionage (logistics, intellectual property) and are pre-positioning disruptive capabilities that could be used in crises.
PNT systems (GPS, AIS) are vulnerable to jamming and spoofing, which can lead to navigational errors and safety risks.
Digitalisation and connected OT increase attack surfaces — remote access, third-party services and satellite links extend exposure, even in remote waters.
Non-state actors (hacktivists) very likely continue DDoS and website defacement campaigns linked to international events; these can still cause real disruption and reputational damage.
Supply-chain compromises and foreign ownership of service providers present additional routes for intrusion, data theft, or denial of service.
Top ransomware families affecting Canada in 2024 (notably many Ransomware-as-a-Service variants) increase the ease and impact of cybercrime affecting ports and service providers.
Mitigations exist: awareness, basic cyber-hygiene, network zoning, OT protections, and preparedness can reduce risk and impact.

Why should I read this?

Short version: if you run, work with, or rely on ports, shipping lines, terminals or marine IT/OT systems — this matters. The report tells you who’s attacking, how they’ll most likely hit you (ransomware, DDoS, PNT interference, supply‑chain compromise), and why digital upgrades actually mean more risk if not properly protected. We’ve read it so you don’t have to — and you should act on the key mitigations now.

Author note

Punchy and practical: This is a high‑priority briefing. The combination of high economic importance, growing digital complexity, and active state and criminal interest makes the MTS a prime target. If you’re responsible for resilience, security or continuity in the sector, treat the detailed guidance and mitigations as urgent.

Context and relevance

The MTS is critical to Canada’s economy and supply chains (over $8.3 billion GDP contribution in 2022; significant share of imports/exports). Cyber incidents can cause safety issues, long supply delays and large economic losses (Maersk/NotPetya example). As ports and vessels adopt sensors, automation and connected OT, adversaries gain more avenues to steal data, disrupt operations or pre-position destructive tools. The report ties into broader trends: rising ransomware-as-a-service, state-backed industrial reconnaissance (e.g. Volt Typhoon), and opportunistic hacktivist campaigns. For decision-makers, the report underscores immediate priorities: harden Internet-exposed systems, secure third-party access, protect PNT integrity, and prepare response/playbooks for ransomware and DDoS.
