Kotliva targeted by fog ransomware group in alleged data breach

• Ransomware group: fog
• Country: Russia
• Sector: Technology

Fog ransomware group claims to have leaked Kotliva data

The threat actor group known as fog has claimed responsibility for a data breach involving the technology organization Kotliva. According to an announcement made on a leak site on March 6, 2025, the group alleges they have successfully exfiltrated and published a significant volume of information belonging to the firm. This incident follows an alleged attack date of March 5, 2025.

Ransomware groups often utilize leak sites to pressure victims into paying ransoms through a tactic known as double extortion. In such scenarios, attackers not only encrypt an organization's systems to disrupt operations but also steal sensitive data, threatening to release it publicly if their demands are not met. This method increases the leverage held by the threat actors, as the threat of data exposure can cause significant reputational and legal damage.

Details of the alleged exfiltration

The fog group has listed data allegedly belonging to Kotliva on their dedicated leak site. The announcement indicates that a substantial dataset has been made available for public access. While the group's identity and methods remain somewhat obscure, as information regarding this group is limited in the public domain, the scale of the claimed theft is notable.

The group claims that the stolen information was extracted from a specific part of the organization's development infrastructure. Specifically, the announcement mentions a 37 GB dataset allegedly extracted from the organization's GitLab infrastructure. The listing names no specific data types within the provided information.

The organization profile

Koltiva is a technology company that provides software solutions for agriculture and supply chain management, digitizing sustainable farming practices. Based in Indonesia, the firm develops data-driven platforms to increase farmers' productivity and ensure traceability.

Potential impact and security implications

This alleged data leak may lead to the exposure of the organization's source code or sensitive development data. Because the data is claimed to have originated from a GitLab infrastructure, the incident could pose significant risks to the organization's intellectual property. Furthermore, the exposure of such technical assets could potentially create security vulnerabilities for third-party integrations that rely on the organization's software ecosystem.

The publication of this data may impact the organization's operational continuity and could potentially serve as a basis for supply chain attacks. When development environments or source code repositories are compromised, attackers can use the information to find flaws in software used by many clients, potentially compromising the entire supply chain. Additionally, given the organization's location in Russia, legal proceedings under relevant local data protection regulations may be initiated following the breach.

To defend against such threats, organizations in the technology and software development sectors often implement several defensive measures. These include enforcing strict access controls and multi-factor authentication for all repository access, implementing continuous monitoring of development environments, and conducting regular audits of third-party integrations. Furthermore, robust backup strategies and incident response plans are essential for maintaining operational continuity in the event of a successful breach.
