On April 13, 2026, the lamashtu Ransomware Group listed ClientSolution EFO Service Srl Logitech Srl Safety on its leak site and claimed to have exfiltrated internal files during a ransomware attack. The number of individuals affected remains unknown, and no further details on the volume or contents of the material have been made public.

What happened

The listing appeared on April 13, 2026. The group states that internal files were taken from the listed entities during a ransomware operation. No information has been released about the timing of the intrusion, the method of initial access, the duration of access, or the quantity of data involved. The number of people whose information may be present in the exfiltrated material is also undisclosed.

Inside lamashtu

Lamashtu is a ransomware group that maintains a public leak site where it posts the names of organizations it claims to have targeted. Groups of this type commonly combine file encryption on victim systems with the threat of publishing stolen data if a ransom demand is not met. Public reporting on the group has documented similar listings against companies in multiple sectors, though independent verification of each claim is rarely available at the time of posting.

ClientSolution EFO Service Srl Logitech Srl Safety Listed by lamashtu Ransomware Group and its sector

The listed names correspond to organizations that provide facility management, technical and operational support, industrial automation solutions, and occupational health services. Entities in these sectors routinely maintain records on clients, employees, vendors, equipment, safety inspections, and operational procedures. A breach affecting such providers can expose information that underpins the daily functioning of the businesses they serve.

The information in question

The only detail released is that internal files were allegedly exfiltrated. The precise categories of data contained in those files have not been disclosed. Organizations of this type commonly hold employee records, client contracts, maintenance logs, safety documentation, and technical specifications, but it is not confirmed whether any of these categories are present in the material referenced by the group.

The real-world impact

Exposure of internal operational files can create follow-on risks for both the affected organizations and the people whose details appear in those files. Client and employee records may be used for targeted fraud or social-engineering attempts. For the companies themselves, the release of proprietary procedures or safety documentation could affect contractual relationships and regulatory compliance obligations. The absence of confirmed data volumes leaves the scale of these risks unquantified at present.

If your data was in this claimed breach

Monitor accounts for unusual activity and consider placing fraud alerts with credit agencies if personal identifiers were involved. Review any communications from the affected organizations for guidance on next steps. Individuals can run a free exposure scan of their email address against known breach data sets to check whether their information has appeared in previously published collections.
