From Cybersecurity to the Era of Cyber Resilience
The question now isn't "how do we block it" — it's "how do we survive it."
On August 12, I attended the Maritime Cybersecurity Conference 2026 (co-hosted by CYTUR and SecurityNews, held concurrently with ISEC 2026) at the COEX ASEM Ballroom in Seoul. Listening to Hanwha Ocean's presentation, "AI-Era Vessels' New Challenges and Responses," I realized the industry's front line is wrestling with exactly the same questions. This article is a write-up of what that talk left me thinking about. Artificial intelligence (AI) is accelerating digital transformation across the shipbuilding and shipping industries. Smart ships, digital twins, remote maintenance, predictive maintenance, and autonomous navigation technologies have become core tools for improving vessel efficiency and safety. But technological progress brings new threats along with it. In cybersecurity, AI has recently begun to be used as an attack tool, fundamentally changing the security landscape. Hacking is no longer the domain of a few specialists — it is expanding into something anyone who can use AI can attempt.
Ⅰ. AI Has Changed the Paradigm of Hacking
In the past, cyberattacks demanded a high level of technical skill. An attacker had to understand a system's architecture, analyze its vulnerabilities, and write attack code by hand. This technical barrier to entry naturally limited attackers to specific nation-state organizations, criminal groups, and professional hacker crews.
But that changed dramatically with the arrival of generative AI. AI can now automatically carry out tasks like network reconnaissance, vulnerability analysis, exploit-code generation, and attack-path discovery. Work that once took months of study and experience is now achievable with natural-language instructions alone. An attacker can acquire a meaningful level of offensive capability simply by describing a goal to AI — without understanding the technical details underneath it.
Ⅱ. What the Shift in Who Attacks Actually Means
The biggest change in the AI era isn't the attack method — it's who is attacking.
In the past, an attacker's expertise determined the level of threat. Now, with AI performing a large share of the attack tradecraft itself, an environment is emerging where even people without much technical skill can attempt an attack. The core element of hacking is shifting from skill to intent.
This means an explosive increase in attempted attacks. Where a small number of specialized groups once targeted a limited set of objectives, going forward it's likely that a much broader, unspecified range of actors will attempt attacks against a much broader range of targets. It's not just the quality of attacks that rises — it's the sheer volume. Because AI can attack multiple targets simultaneously, mass, automated attacks are expected to increase more than narrowly targeted attacks against a specific company or a specific vessel.
An even more concerning point is that AI can now understand the specialized protocols used in the maritime domain. In the past, a lack of knowledge about shipboard communication systems and automation systems made this domain genuinely hard to access — but AI is now reaching a level where it can analyze these protocols and generate attack code from publicly available technical documentation alone.
Ⅲ. Why Hacking a Ship Is Dangerous
In a typical enterprise environment, a cyberattack often leads to data leakage, service disruption, or financial loss. That's serious enough on its own — but a ship is a different situation.
A ship's digital systems are directly connected to the operational technology (OT) environment that controls its physical equipment. Navigation systems, engine automation systems, power management systems, and cargo management systems are all connected over the network — and if any of these systems is attacked, it can turn into a physical accident.
For example, if a navigation system is manipulated, a ship could follow the wrong course or run aground. If an engine system is compromised, the vessel could lose propulsion and drift at sea. If a power system is disabled, the entire ship could lose electrical power. If a cargo management system is attacked, cargo damage or a stability problem could trigger a safety incident.
In the end, onshore you lose data — but on a ship, you can lose propulsion, steering, and power. That's a fundamentally different kind of risk. The defining feature of ship security is that a cyberattack can turn directly into a safety incident.
Ⅳ. Main Attack Paths That Target Ships
Most attacks against ships follow a fairly consistent process.
These outcomes can escalate into serious incidents such as collisions, groundings, or disruption to port operations.
Ⅴ. New Security Threats in the AI Era
As AI begins to be used in ship operations, new kinds of attacks are emerging as well.
- Prompt Injection — an attack technique that feeds malicious instructions to an AI system to make it bypass existing security policies. As AI becomes more deeply embedded in ship operations, this could become a very significant threat.
- Data Poisoning — a method where an attacker deliberately manipulates sensor or voyage data so that AI learns from corrupted information. If location or navigation-related data is poisoned, AI becomes far more likely to make a dangerous decision.
- Errors in AI-Generated Control Logic — as equipment manufacturers increasingly use AI to develop control software, there is a real possibility that unverified code ends up running actual ship operations. There is also a growing concern that multiple AI agents operating independently could create unauthorized data exchanges or hidden communication channels.
Ⅵ. From Cybersecurity to Cyber Resilience
In the AI era, a defense-only security strategy is no longer enough. Blocking attacks still matters, but the ability to keep operating safely and recover quickly once an attack has already happened is becoming just as important. This is what's known as Cyber Resilience.
Building cyber resilience requires the following, in parallel:
- Incorporating AI-driven attack scenarios into risk-analysis processes
- Defining AI agents themselves as managed assets and continuously monitoring them
- Building a Human-in-the-Loop framework that requires human approval for critical control commands
- Verifying the integrity of AI training data, building anomaly-based detection capability, and strengthening supply-chain security
Security needs to go beyond simply blocking outside intrusions — it has to be designed so a ship's core functions keep working even under attack.
Ⅶ. Conclusion
AI is a core technology that will determine the future competitiveness of the shipping industry. But at the same time, AI is becoming a new threat that lowers the barrier to hacking and expands the scale of attacks. Attackers are no longer only professional hackers — anyone who can use AI is a potential threat actor.
The shipping industry can no longer afford to think only about "how do we block an attack." It also has to think about "how do we keep operating safely even after an attack happens."
Going forward, competitiveness won't be decided by the company with the strongest shield — it will be decided by the company with the resilience to survive safely, no matter what kind of attack it faces.
