RansomHub claims exfiltration of data from cda.be

The ransomware group known as RansomHub has announced that it has successfully exfiltrated a significant amount of data belonging to the Belgian organization cda.be. According to the group's announcement on its leak site, the breach involves a substantial volume of information, which the threat actors claim to have obtained during a process that allegedly took place on February 18, 2025. The announcement regarding this incident was made public on March 5, 2025.

Ransomware leak sites are frequently utilized by cybercriminal groups to exert maximum pressure on targeted organizations. By publishing claims of a successful breach and listing stolen data, these groups aim to damage the victim's reputation and coerce them into paying a ransom. This tactic is a hallmark of modern ransomware operations, where the threat of public exposure is used as a primary leverage tool.

Details of the claimed data theft

The RansomHub group has claimed that the total volume of data stolen from cda.be amounts to 170 GB. While the group has listed the stolen information on their platform to increase pressure on the organization, they have not provided information regarding the specific number of files involved or the specific amount of the ransom demand.

The announcement specifies that the exfiltrated data includes a variety of sensitive information types. The group claims to have obtained the following:

• IDs
• Insurance data
• Employee data
• Contracts
• Proposals
• Complaints
• Other sensitive information

The presence of such diverse data types suggests a broad compromise of the organization's internal documentation and personal records.

About cda.be

CDA is a logistics and transportation company based in Belgium. The company provides international shipping, warehousing, and supply chain management services. Given its role in the transportation sector, the organization manages complex logistical networks and significant amounts of sensitive client and operational data.

Potential risks and implications of the breach

The alleged exfiltration of this data poses several significant risks to both the organization and the individuals whose information was compromised. For the employees and customers of cda.be, the stolen data—which includes IDs and insurance information—could be used by malicious actors for identity theft or to conduct highly targeted phishing attacks. These types of attacks often use stolen personal details to gain trust and trick individuals into revealing more sensitive credentials.

Furthermore, because the organization is based in Belgium, this incident may lead to legal consequences under the EU General Data Protection Regulation (GDPR), which mandates strict protections for personal data and imposes heavy penalties for failures in data security. The organization may also face significant operational disruptions and long-term reputational damage resulting from the breach.

The nature of this attack suggests the use of double extortion tactics. In a double extortion scenario, attackers not only encrypt an organization's systems to disrupt operations but also steal sensitive data to threaten the victim with its public release. RansomHub has reportedly worked with ALPHV affiliates in the past, which is a factor in assessing the likelihood of such tactics being employed. It is worth noting that information regarding RansomHub is relatively limited; the group emerged in early 2024 and reportedly ceased operations in early 2025.

To defend against such threats, organizations in the logistics and transportation sector can implement various defensive measures. These include maintaining robust backup solutions, implementing multi-factor authentication (MFA) across all systems, and conducting regular security awareness training for employees to recognize phishing attempts. Additionally, continuous monitoring of network traffic and strict access controls can help mitigate the impact of unauthorized data exfiltration.
