What happened
The incident was first noted through the threeam group's listing on June 12, 2026. The available record indicates that a ransomware attack on ws.com.br resulted in the removal of internal files. No information has been provided on the date of the intrusion, the method used to gain access, or the quantity of data involved.
Who is threeam?
The threeam ransomware group is a threat actor that carries out operations involving system encryption and data exfiltration. Groups of this type commonly maintain sites where they list organizations they claim to have targeted. In the present case, the group claims to have obtained material from ws.com.br by listing the company on its site.
About ws.com.br
WS Group Brasil provides operations and business services in Brazil, with activities that include logistics, technical support, contract administration, and labor-intensive service delivery. The company works with a mix of government, institutional, and commercial clients, which means it routinely processes records connected to contracts, personnel, and operational activities across those sectors.
The information in question
The listing refers only to internal files that were allegedly exfiltrated. No specific data types or file categories have been identified publicly. While organizations engaged in logistics and contract administration typically maintain records such as employee details, client information, and operational documents, the exact contents of the material taken in this instance remain unconfirmed.
Why it matters
Any exposure of internal files could affect individuals whose information appears in those records, particularly if contract or personnel data is involved. The organization may also face questions from clients about the handling of shared information and the steps taken to limit further distribution of the material.
Were you affected?
People who have interacted with ws.com.br or its clients can review their accounts for unexpected activity and adopt basic account protections such as unique passwords and multi-factor authentication.

Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
