www.sanmarti.es Listed by kraken Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On 3 April 2025 the domain www.sanmarti.es, operated by Transportes Sanmarti SA, appeared on a leak site operated by the ransomware group known as kraken. The group claims that internal files were exfiltrated during a ransomware attack. Public reporting does not state how many people may be affected, nor does it confirm the precise contents of the material or the technical method used. The listing itself is an unverified claim by the actors.

For a transport and logistics firm the potential exposure of internal records can carry practical consequences for employees, partners and customers, even when the full scale remains undisclosed. What follows summarises only the facts that have been reported and the established public context around the actors and the sector.

What happened

According to the available record, www.sanmarti.es was listed by the kraken ransomware group on 3 April 2025. The reported summary identifies the organisation as Transportes Sanmarti SA and states that internal files were exfiltrated in a ransomware attack. No further operational details—such as the date of initial access, the encryption status of systems, the volume of data taken, or any ransom demand—have been made public. The number of individuals whose information may be involved is listed as unknown. The only concrete assertion is the group’s own claim, published via a Tor-hosted leak-site page, that exfiltration occurred.

Who is kraken?

Kraken is a ransomware operation that has been observed conducting double-extortion campaigns: encrypting victim systems while also copying data and threatening to publish it if payment is not made. Like other groups of this type, it maintains a dark-web leak site on which it posts victim names and, in some cases, sample files. Public reporting on kraken’s earlier activity describes the use of common initial-access methods such as phishing, exploitation of exposed remote services, and the deployment of commodity ransomware tooling. The group’s listing of any particular organisation should be treated as a claim until independently verified; the mere appearance of a name on a leak site does not by itself prove the full extent of compromise.

Who is www.sanmarti.es?

www.sanmarti.es is the public web presence of Transportes Sanmarti SA, a Spanish transport and logistics company. Firms in this sector typically manage vehicle fleets, shipment schedules, customer contracts, employee records and operational documentation. Because logistics companies sit at the intersection of physical goods movement and commercial data flows, a breach can affect both the organisation’s day-to-day operations and the personal or commercial information of people who interact with it. The public record does not indicate whether the company has issued its own statement confirming or denying the listing.

The information in question

The only data category named in the available facts is “internal files exfiltrated in ransomware attack.” No inventory of specific file types, databases or personal-data categories has been released. Organisations of this kind ordinarily hold employee personnel files, customer contact and billing details, shipment manifests, invoices and internal correspondence. Whether any of those categories were among the material claimed by kraken remains unconfirmed. Readers should therefore treat any assertion about exact contents as speculative until further evidence appears.

The real-world impact

If internal files containing personal identifiers, financial details or operational schedules were taken, affected individuals could face risks such as targeted phishing, identity fraud or unsolicited contact. For the company itself the consequences may include temporary disruption of logistics systems, contractual notification obligations under data-protection rules, and the need to rebuild trust with partners. Because the number of people affected is unknown and the precise data types are undisclosed, the scale of these risks cannot yet be quantified. The listing alone does not establish that systems remain encrypted or that data have been publicly released beyond the group’s claim.

Were you affected?

If you have worked with, been employed by, or otherwise shared personal information with Transportes Sanmarti SA, consider the following practical steps:

• Monitor bank and credit statements for unexpected activity and enable transaction alerts where available.
• Treat unsolicited emails or calls that reference the company or recent shipments with caution; verify any request through a known official channel.
• Change passwords on accounts that may have reused credentials linked to the organisation, and enable multi-factor authentication wherever possible.
• Request a free exposure scan of your email address against known breach data sets to see whether your details have already appeared in public dumps.

Public detail on this incident remains limited. Further confirmed information, if it emerges, will provide a clearer picture of who may need to take additional protective measures.
