martec.it Listed by tengu Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On February 25, 2026, the ransomware group tengu listed martec.it on its leak site. The entry states that internal files were exfiltrated in a ransomware attack against the company. No figure for the number of people affected has been released, and additional technical details remain undisclosed at this time.

The listing constitutes a claim by the group rather than a verified account from the victim organization. Public reporting has not yet confirmed the scope of any data access or the operational impact on martec.it systems.

Breaking down the breach

The only confirmed element is the February 25, 2026 listing itself. It references exfiltration of internal files during a ransomware incident. No information has been made public about the date of the intrusion, the volume of data taken, the encryption status of systems, or whether a ransom demand was issued or met. The number of records or individuals involved is also not stated.

Who is tengu?

Tengu is a ransomware operator that maintains a leak site to publish data it claims to have stolen from targeted organizations. Like other groups in this category, it typically combines file encryption on victim networks with the threat of data publication to pressure payment. The group has appeared in public reporting on multiple incidents involving commercial and industrial targets, though specific claims about any single victim require independent confirmation.

martec.it and its sector

Martec Marine forms part of an Italian privately owned group that has supplied damage-control and integrated safety systems since 1994. Its customers include naval vessels and large passenger ships. The company designs and installs hardware and software for fire detection, incident management, and damage-control functions on military and commercial maritime platforms.

Organizations operating in the maritime defense and safety sector routinely handle technical specifications, supplier information, and operational data related to vessel safety systems. A breach affecting such an entity therefore touches both commercial records and material that can carry regulatory or security implications.

What was likely exposed

The listing refers only to “internal files exfiltrated in ransomware attack.” No inventory of file types, categories, or record counts has been released. Companies of this kind commonly store engineering documents, customer and supplier correspondence, configuration data for installed systems, and internal administrative records. The precise contents of the exfiltrated material remain unconfirmed.

Why it matters

Exposure of internal files from a maritime safety supplier can create downstream risks for the vessels and operators that rely on its equipment. Even without confirmed personal data, the release of technical or operational documents may assist further targeting or complicate incident response for affected clients. For the company itself, the incident adds the tasks of forensic review, notification obligations, and potential remediation of any compromised systems.

If your data was in this claimed breach
