Babuk2 ransomware group lists sincorpe.org.br on its leak site

• Ransomware group: Babuk2
• Country: Brazil
• Sector: Professional Services
• Announcement date: January 27, 2025

The Babuk2 ransomware group has officially listed the Brazilian organization sincorpe.org.br on its leak site. According to the announcement made on January 27, 2025, the threat actors claim to have successfully exfiltrated a significant volume of data belonging to the entity.

Details of the alleged attack

The threat actor known as Babuk2 listed sincorpe.org.br on its dedicated leak site on January 27, 2025. In the announcement, the group alleges that it has obtained database dumps that cover a specific timeframe, specifically the period between July and December. To support their claims of a successful breach, the group has provided a 200 MB sample of the data within the announcement.

While the group has published this information, public information regarding the specific identity and technical capabilities of the Babuk2 group remains limited. This type of activity is characteristic of modern ransomware operations, where threat actors use leak sites to pressure victims through double extortion. In such scenarios, attackers not only encrypt an organization's systems but also threaten to release sensitive data to the public to maximize leverage during ransom negotiations.

Data involved in the leak

The announcement specifies that the alleged breach involves a total of 11 GB of data. The group claims that these database dumps contain various types of sensitive information. According to the details provided by the attackers, the stolen data includes:

• Full names
• Source code
• Category information
• Course data

The inclusion of source code in such leaks is particularly concerning for organizations, as it can provide a roadmap for future malicious activities. When attackers gain access to an organization's proprietary code, they can perform deep vulnerability analysis to identify weaknesses that can be exploited in subsequent, more targeted attacks.

About sincorpe.org.br

Sincorpe is an organization operating in Brazil. The entity provides services primarily in the fields of corporate services and professional consulting.

Impact and risk assessment

The allegedly leaked data may pose significant secondary risks to the institution's employees and members. Specifically, the exposure of full names and other details can lead to identity theft or be utilized in highly targeted phishing attacks. Furthermore, the leaked source code presents a long-term security risk, as it may be used by various actors to conduct vulnerability analysis for future attacks against the organization.

Because the institution is based in Brazil, this incident may lead to legal and administrative sanctions under the LGPD (General Data Protection Law). The organization may also face challenges regarding its operational continuity and reputation management due to the public nature of the leak. The provided 200 MB sample serves as a potential indicator of the authenticity of the leak.

For organizations in the professional services and consulting sectors, such incidents highlight the importance of robust data protection strategies. Common defensive steps include implementing strict access controls, maintaining regular offline backups, and conducting frequent security audits to detect unauthorized access early. Protecting the integrity of source code and ensuring compliance with regional data protection laws, such as the LGPD, are critical components of a modern cybersecurity posture to mitigate both legal and operational risks.
