Company said the system that it used was accessed without authorisation by a third party and determined that certain data, including personal information, may have been taken from the system.
NYK Line has disclosed a cybersecurity incident involving unauthorized access to one of its marine fuel procurement systems, resulting in the potential exfiltration of sensitive data, including personal information. The Japanese shipping major confirmed that the breach was identified on the afternoon of 24 March, raising concerns over the security of digital procurement infrastructure within the maritime industry.
According to the company, the affected system was immediately isolated from the network upon detection of the intrusion, and its usage was suspended to prevent further impact. NYK stated that while certain data may have been accessed and extracted by a third party, there is currently no evidence of data encryption or any ransom demands associated with the incident.
In response to the breach, NYK established an internal task force to investigate the scope and cause of the unauthorized access, as well as to implement necessary remediation measures. The company acted swiftly to contain the situation, restoring the compromised system by 27 March after initial safeguards were put in place.
On the same day as the system restoration, NYK submitted a preliminary report to Japan’s Personal Information Protection Commission, along with notifications to other relevant authorities in applicable jurisdictions. The company further escalated the matter by reporting the incident to law enforcement authorities on 31 March.
Despite the data breach, NYK noted that no secondary damage or misuse of the compromised information has been confirmed at this stage. The absence of financial extortion or ransomware activity suggests that the attack may have been focused on data extraction rather than disruption.
The incident highlights growing cybersecurity risks facing maritime and logistics companies, particularly as critical procurement systems become increasingly digitized and interconnected. These platforms often handle sensitive operational and personal data, making them attractive targets for threat actors.
NYK emphasized that it is treating the incident with the utmost seriousness and is committed to strengthening its cybersecurity posture. The company stated that it will enhance its security measures and management framework while continuing to closely monitor the situation.
As investigations continue, the breach serves as a reminder of the importance of robust cybersecurity defenses and rapid incident response strategies in protecting critical supply chain systems from evolving cyber threats.
