Key Takeaways
- Over 80% of cyber‑alert activity in monitored maritime environments now originates inside crew network zones, driven by compromised credentials rather than technical exploits.
- Attackers frequently reuse passwords, exploit dormant vendor accounts, or leverage shared admin logins that cannot be traced to individuals.
- Ships traditionally exhibit poorer identity hygiene than onshore corporate networks—shared bridge accounts, generic vendor logins, lack of multi‑factor authentication (MFA), and absent central directories are common.
- The rollout of Low Earth Orbit (LEO) satellite connectivity has expanded the attack surface, making crew networks resemble hotel Wi‑Fi in bandwidth and threat profile.
- Regulatory frameworks (IMO guidance, IACS UR E26/E27, NIS2, USCG/MTSA) and cyber‑insurance markets now mandate strong identity governance, access control, segmentation, and continuous monitoring.
- Dualog’s maritime‑focused Digital Identity platform provides centralized identity‑and‑access management (IAM), MFA support, federation with existing providers, and offline capability when satellite links drop.
- By attributing every login to a real person, retiring shared accounts, and enabling automated deprovisioning, the solution delivers the visibility, control, and auditability required for modern cyber security at sea.
The Evolving Maritime Threat Landscape
Cyber threats targeting the shipping industry have undergone a fundamental shift. While malware and zero‑day exploits still appear in threat reports, the dominant attack vector today is the abuse of compromised identities. Threat intelligence gathered by Dualog across numerous monitored vessels shows that more than four‑fifths of all alert activity now springs from within crew network zones. Attackers are no longer relying on sophisticated code to breach perimeter defenses; instead, they steal, reuse, or poorly manage credentials to walk straight into vessel and company systems using legitimate‑looking access.
Credential‑Driven Attacks Dominate
Geir Inge Jensen, Chief Information Security Officer at Dualog and an ISO committee member for Ships and Marine Technology standardization, emphasizes that most incidents his team supports begin with valid credentials used by the wrong person. A typical scenario might involve a seafarer reusing a password from a personal account, a vendor account left active months after a contract ended, or a shared administrator login that no one can attribute to a specific individual. These weaknesses enable attackers to move laterally, exfiltrate data, or manipulate navigation and operational technology without triggering traditional malware‑based alerts.
Quantifying the Credential Problem
According to Dualog’s threat‑intelligence feeds, over 80% of alert activity in monitored maritime environments originates inside crew zones. This statistic underscores how credential misuse has eclipsed other threat types in frequency and impact. The data also reveals that many alerts involve anomalous login patterns—such as logins at odd hours, from unexpected geographic locations, or via devices not previously associated with a user—indicating that stolen credentials are being actively abused rather than merely tested.
Why Ships Lag Behind Ashore Networks
Historically, maritime identity hygiene has lagged behind that of onshore corporate networks. Bridge systems often rely on shared accounts for convenience, vendor logins remain generic and rarely rotated, multi‑factor authentication is seldom deployed, and there is frequently no central directory service to enforce uniform policies. These practices create a fertile ground for credential‑based attacks, as there is little to no mechanism to verify who is actually using a given set of credentials at any moment.
Impact of LEO Connectivity on Exposure
The recent proliferation of Low Earth Orbit (LEO) satellite constellations has dramatically increased bandwidth availability at sea, but it has also altered the threat profile of crew networks. With LEO links providing internet speeds comparable to hotel Wi‑Fi, seafarers now enjoy the same online conveniences—and the same risks—as passengers onshore. The expanded connectivity surface means that compromised credentials can be exploited from virtually anywhere, and the lack of mature security controls on these links amplifies the potential damage from a single stolen password.
Regulatory and Insurance Pressures Mount
Recognizing the growing credential threat, regulators and insurers have begun to tighten requirements. The International Maritime Organization (IMO) has issued guidance emphasizing identity governance, while the International Association of Classification Societies (IACS) Unified Requirements E26 and E27 mandate access control and segmentation for shipboard systems. The European Union’s NIS2 Directive and the United States Coast Guard’s Maritime Transportation Security Act (MTSA) oversight likewise impose strict monitoring and reporting obligations. Concurrently, cyber‑insurance premiums spiked in 2025, with policies increasingly excluding losses tied to poor access hygiene, thereby creating a financial incentive for shipping companies to strengthen their identity and access management practices.
The Strategic Shift Toward Identity Management
Given that traditional perimeter‑focused defenses are less effective against credential‑driven incursions, maritime operators must re‑prioritize identity management, access governance, and continuous visibility across both onboard and shoreside systems. Jensen argues that the appropriate response is not to blame crew members for lax password habits but to redesign systems so that secure behavior becomes the default. Centralized identity platforms that enforce least‑privilege principles, require multi‑factor authentication, and provide immutable audit trails are essential components of a modern maritime cyber‑security posture.
Introducing Dualog Digital Identity
To address these needs, Dualog has launched its maritime‑focused identity and access management solution, Digital Identity. The platform is purpose‑built for the unique connectivity realities of ships: it federates with existing identity providers (such as Azure AD, Okta, or LDAP), supports MFA even when satellite links are intermittent, and continues to enforce policies locally when the satcom connection drops. By offering a single pane of glass for managing who can access what across an entire fleet, Digital Identity eliminates the guesswork inherent in disparate, ad‑hoc credential practices.
Operational Benefits for Fleet IT Teams
From a practical standpoint, fleet IT teams experience immediate gains in visibility and control. Every login event is attributable to a real person, which facilitates rapid incident response and forensic analysis. Shared accounts—once a convenience but now a liability—can be identified and retired systematically. Vendor engagements can be deprovisioned centrally the moment a contract ends, reducing the window of exposure from dormant credentials. Audit trails are generated by default, satisfying regulatory reporting requirements and providing evidence for insurance underwriters. Collectively, these capabilities furnish shipping companies with the foundation needed for modern cyber security at sea: clear ownership of access, alignment with evolving regulatory expectations, and the confidence that every action across the fleet can be traced to a genuine individual.
Conclusion: Building Resilience Through Identity
The maritime sector’s threat landscape has undeniably shifted from exploitation of software vulnerabilities to exploitation of human and procedural weaknesses in identity management. As attackers increasingly rely on stolen or poorly managed credentials to infiltrate vessel and company systems, the industry must adapt by elevating identity governance to the same level of importance as network firewalls and endpoint protection. Dualog’s Digital Identity solution offers a concrete pathway to achieve that shift, delivering the centralized control, MFA enforcement, and offline resilience necessary to defend against today’s credential‑centric attacks while satisfying the stringent demands of regulators, insurers, and the seafarers who keep global trade moving. By embracing identity‑first security, shipping companies can not only reduce their risk profile but also foster a culture where secure access is routine, auditable, and inherently tied to the individuals who rely on those systems every day.
