Sertrans Listed by thegentlemen Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On June 20, 2026, the ransomware group thegentlemen listed Sertrans on its site, claiming to have carried out an attack that resulted in the exfiltration of internal files. The number of individuals whose information may be involved is not known, and no further details about the scale or timing of the incident have been made public. This development matters because Sertrans operates in the logistics sector, where records often include details about shipments, business partners, and operational processes that can extend across multiple countries.

Breaking down the breach

The only confirmed information is the listing itself and the statement that internal files were taken during a ransomware operation. No figure has been released for the volume of data, the number of records, or the date when the intrusion occurred. It is not known whether any material has been published or whether negotiations took place.

The group behind it: thegentlemen

Thegentlemen is a ransomware operator that maintains a leak site to list organisations it claims to have targeted. The group follows the common pattern of encrypting systems and removing copies of data, then using the threat of publication to press for payment. Its listings are presented by the group as evidence of successful intrusions, though independent confirmation of each claim is not always available.

Sertrans and its sector

Sertrans is a Spanish company founded in 1987 that began as a family business and expanded into a larger provider of road haulage, parcel delivery, and international freight services. It maintains operations connecting Spain with other parts of Europe and with Morocco. Logistics firms of this type routinely manage records that document the movement of goods, customer contracts, and coordination with carriers and warehouses.

What data was at risk

The listing refers only to internal files. The precise contents of those files have not been disclosed. Organisations in this sector commonly hold shipment documentation, client contact information, carrier agreements, and operational schedules, but it is not confirmed whether any of these categories were present in the material removed.

Why it matters

Exposure of internal logistics records can reveal patterns of business activity and relationships between companies. For individuals, the main concern is the possible appearance of contact details or transaction references in data that later circulates. For the organisation, the incident adds to the operational disruption already associated with ransomware and raises questions about how similar records are protected across the supply chain.

If your data was in this claimed breach

Begin by watching for unusual activity in any accounts or services linked to the company. Use strong, unique passwords and enable multi-factor authentication where available.
