RansomHub claims to have stolen data from Eucatex

The RansomHub ransomware group has published a claim on its leak site involving the Brazil-based manufacturing company Eucatex. According to the group's announcement, approximately 150 GB of data allegedly belonging to the organization has been compromised. The threat actor group announced this development on May 14, 2024, claiming the attack occurred on the same day.

The group stated that their attempts to negotiate with Eucatex were unsuccessful. Following the failure of these negotiations, the attackers proceeded to list the company's data on their public leak site. In a direct challenge to the organization, RansomHub has disputed Eucatex's claims regarding the security of its data. The group asserts that the stolen information is not limited to general files but specifically includes sensitive records from the company's Enterprise Resource Planning (ERP) and Customer Relationship Management (CRM) systems.

Details of the alleged data leakage

The information currently available for sale on the RansomHub leak site is claimed to be substantial in volume. While the specific file count was not provided by the group, the total size of the alleged breach is reported to be 150 GB. The contents of this data set are described as being highly sensitive and operationally significant.

The alleged data leakage includes the following types of information:

• Client information
• Contractor data
• Financial documents
• Non-disclosure agreements (NDAs)
• Application source codes
• ERP database records
• CRM database records

The inclusion of application source codes and database records suggests a high level of access to the organization's internal technical infrastructure.

Analysis of the threat and potential impact

The actions taken by RansomHub represent a significant risk to Eucatex. By making this data available for sale, the group is employing double extortion tactics, a method where attackers not only encrypt an organization's systems but also threaten to release sensitive information to pressure the victim into paying a ransom. RansomHub, which emerged in early 2024 and is reported to have absorbed former affiliates of the ALPHV group, is known for utilizing this high-pressure tactic.

The exposure of this data could lead to several critical consequences for the organization. The leakage of ERP and CRM records poses secondary risks to the company's operational processes and its relationships with third parties. Furthermore, the theft of application source codes and financial documents could compromise the company's intellectual property and provide a foundation for highly targeted phishing attacks against employees or partners.

From a regulatory perspective, the company may face significant challenges under Brazil's LGPD (Lei Geral de Proteção de Dados) regulations. Such a breach may trigger mandatory data breach notification requirements and could potentially lead to administrative sanctions. The exposure of client and commercial data through these leaked files creates a broad surface for legal and reputational damage.

Defensive considerations for the manufacturing sector

For organizations operating in the manufacturing sector, incidents of this nature highlight the necessity of robust cybersecurity frameworks. Protecting sensitive ERP and CRM databases is critical to maintaining operational integrity and protecting trade secrets. Implementing strict access controls, multi-factor authentication, and continuous monitoring of database queries can help mitigate the risk of unauthorized data extraction.

Furthermore, because ransomware groups often target intellectual property, such as source code, organizations should prioritize the encryption of sensitive repositories and maintain offline, immutable backups to ensure business continuity. As seen in this case, the threat of data exposure necessitates a proactive approach to data governance and compliance with regional privacy laws to minimize the impact of potential regulatory scrutiny.
