Hunters ransomware group claims attack on Groupe Delcourt

The Hunters ransomware group has listed Groupe Delcourt on its dedicated leak site, claiming to have successfully exfiltrated sensitive data from the organization. This announcement marks a significant escalation in the threat landscape facing the retail sector, as the group asserts that it has not only stolen information but has also compromised the target's digital infrastructure through encryption.

Ransomware attacks of this nature typically involve a multi-stage process where attackers gain access to a network, escalate privileges, and move laterally to locate high-value assets. Once the data is identified, the attackers often employ a double extortion tactic. In this scenario, the threat actors attempt to extort the victim twice: first, by demanding a ransom to prevent the decryption of encrypted systems, and second, by threatening to publish the stolen data on a public leak site if the demands are not met. This method increases the pressure on organizations, as the threat of public exposure can lead to severe reputational and legal consequences.

Details of the alleged breach

According to the announcement made by the Hunters group on April 6, 2025, the attack involved both data exfiltration and system encryption. The group claims to have taken control of the organization's systems, rendering them inaccessible through encryption. This type of disruption can halt business operations, affecting everything from supply chain management to customer service and internal communications.

Regarding the specific volume of information involved in this incident, the group has provided the following claims:

• Total data volume of 3.7 TB
• Approximately 1,958,191 files

While the scale of the data theft is substantial, the group has not provided any specific details regarding the nature or content of the allegedly exfiltrated files. No information has been disclosed as to whether the data includes customer records, financial documents, or internal corporate communications. The listing remains limited to the total volume and file count.

Organization profile: Groupe Delcourt

Groupe Delcourt is a France-based retail company specializing in the distribution and sale of cleaning products, hygiene supplies, and industrial equipment. The company offers a wide range of products to both professional clients and individual consumers.

Potential implications and security considerations

The claims made by Hunters International could lead to significant disruptions in the operational processes of Groupe Delcourt. As the specific nature of the allegedly exfiltrated data remains unclarified, there is a heightened risk that sensitive information belonging to customers or employees could be exposed. In the event that personal data is compromised, the organization may face legal sanctions and administrative procedures under the General Data Protection Regulation (GDPR), given its operations are based in France.

Furthermore, it is important to note that the Hunters group is assessed to be derived from Hive code. This connection suggests that the group may employ secondary extortion tactics, which can complicate the incident response process. Organizations facing such threats should prioritize a thorough assessment of their data security protocols and consider notifying the relevant authorities regarding a potential breach.

For organizations operating within the retail and e-commerce sectors, such incidents underscore the necessity of robust cybersecurity frameworks. Defensive strategies often include implementing multi-factor authentication, maintaining offline backups, and conducting regular network segmentation to prevent lateral movement by attackers. Additionally, continuous monitoring and rapid incident response capabilities are essential to mitigate the impact of both encryption and data exfiltration events.
