Researchers Expose Hack that Could Hand Attackers Full Control of Ship’s Engine, Navigation and Power

Why It Matters

The vulnerabilities demonstrate how a single cloud‑based maritime IoT platform can become a bridge from the internet to a ship’s engine room, underscoring the urgent need for technical verification of cyber‑resilience beyond regulatory checklists.

Key Takeaways

• Remote browser can control propulsion, navigation, power.
• Vulnerabilities stem from client‑side password reset tokens.
• Patch released after responsible disclosure, no known exploitation.
• Maritime cyber incidents rose 100% in 2025.
• E26/E27 standards demand technical verification beyond paperwork.

Pulse Analysis

The SmartShipWeb breach highlights a growing attack surface in maritime operations as vessels adopt cloud‑based IoT platforms for real‑time monitoring. By exploiting a weak password‑reset mechanism that generates tokens client‑side, attackers can intercept authentication data and gain unfettered access to the ship’s file system. Once inside, they mapped nearly 2,700 Modbus registers and hundreds of controllable points across propulsion, navigation and safety subsystems, enabling scenarios such as GPS spoofing or total loss of propulsion—all without any additional authentication. This chain of common web flaws illustrates how traditional cybersecurity oversights can translate into catastrophic operational risks when applied to critical maritime infrastructure.

Regulators are responding with stricter mandates, notably the IACS Unified Requirements E26 and E27 that obligate newbuilds to meet defined cyber‑resilience standards. However, Rudra’s advisory warns that compliance on paper is insufficient; technical validation of platform architectures is essential. The swift patch rollout by Smart Ship Hub, coordinated through Singapore’s Cyber Security Agency, demonstrates effective responsible disclosure but also reveals that many operators may still rely on legacy systems lacking such rigorous scrutiny. As the industry moves toward greater digital integration, verification processes must evolve to test for end‑to‑end attack vectors rather than isolated code reviews.

The broader trend is unmistakable: maritime cyber incidents surged by over 100 % in 2025, and similar vulnerabilities have emerged in other shipboard gateways like NAVTOR’s NavBox. This escalation signals that attackers are increasingly targeting the connective tissue between ship and shore. Operators should prioritize continuous monitoring, zero‑trust network segmentation, and regular penetration testing of IoT platforms. Investing in robust security architectures now can prevent the costly loss of control that could jeopardize crew safety, cargo integrity, and global supply chains.
