• Country: Brazil
• Sector: Manufacturing
• Announcement date: January 16, 2025

The Brazilian manufacturing firm Solarium Revestimentos has been listed on the RansomHub ransomware group's leak site. This listing, appearing on January 16, 2025, serves as a public claim by the threat actors that they have successfully gained unauthorized access to the organization's internal network.

The claimed attack and event details

According to the announcement made by the RansomHub group, the threat actors claim to have targeted the entity on January 16, 2025. The group has published various documents on their leak site that are claimed to be part of the company's internal operations. This public listing is intended to support the group's claim of having successfully breached the organization's network infrastructure.

Ransomware groups often utilize leak sites as a tool for double extortion. In these scenarios, attackers do not merely encrypt an organization's data to disrupt operations; they also steal sensitive information to use as leverage. By threatening to release stolen data publicly, the attackers aim to pressure the victim into paying a ransom to prevent the exposure of confidential information. This tactic increases the pressure on the victim, as the reputational and legal consequences of a public data leak can be devastating.

Data allegedly involved in the leak

The threat actor has shared screenshots that purportedly contain sensitive information belonging to the organization. The content of these screenshots suggests that the breach involves various aspects of the company's business operations and administrative records. The specific types of data mentioned in the claim include:

• Supplier payment records
• Business partner contact information
• Product inventory data

While the specific volume of the data or the exact number of files stolen have not been disclosed by the group, the presence of these documents indicates a potential exposure of internal business processes and stakeholder information.

About Solarium Revestimentos

Solarium Revestimentos is a Brazil-based manufacturing company. The organization specializes in the production of high-quality concrete coverings and flooring solutions designed for various architectural projects.

Impact assessment and organizational risks

The exposure of this data may create negative impacts on the company's supply chain and its existing commercial relationships. Because the leaked information includes contact details for business partners and supplier payment records, there is an increased risk that these third parties may be targeted by subsequent phishing attacks or other forms of social engineering.

Furthermore, under Brazil's LGPD regulations, the company may be required to fulfill specific data breach notification obligations. Such regulatory requirements often follow incidents where personal or sensitive business data is compromised. Given the past activities of the RansomHub group, it is considered that this situation may lead to secondary extortion attempts, where attackers attempt to squeeze more money from the victim after the initial breach.

The long-term risks to the company's operational security and commercial reputation may be observed as a result of this incident. For organizations in the manufacturing sector, maintaining the integrity of supply chain data and inventory details is critical for operational continuity. To mitigate such risks, organizations typically focus on strengthening network security, implementing strict access controls, and conducting regular audits of their data handling processes to ensure compliance with regional data protection laws.
