Qilin ransomware group lists compagnons-du-devoir.com on its leak site

• Ransomware group: Qilin
• Country: France
• Sector: Education
• Announcement date: May 16, 2025

The Qilin ransomware group has claimed responsibility for a data breach involving the Association ouvrière des Compagnons du Devoir et du Tour de France. The threat actor has listed the entity associated with the domain compagnons-du-devoir.com on its dedicated leak site, signaling a potential targeted attack against the French non-profit organization.

The details of the claim

According to the announcement made on May 16, 2025, the Qilin ransomware group has listed the entity associated with the domain compagnons-du-devoir.com on its leak site. The threat actor has stated that the organization's data will be available for download starting from May 25, 2025. This timeline suggests a calculated approach by the attackers to maximize the impact of their threat.

The group appears to be employing double extortion tactics. In such scenarios, ransomware actors do not merely encrypt an organization's systems to disrupt operations; they also exfiltrate sensitive data. By threatening to publish this stolen information on a public leak site, the attackers aim to increase the pressure on the organization to meet their demands. This method leverages the threat of public exposure to coerce the victim into paying a ransom.

Data involved in the alleged leak

While the specific volume and count of the files have not been disclosed, the group has provided visual evidence to support their claims. Screenshots provided by the threat actor display samples of various documents that have allegedly been stolen from the organization's systems. These samples indicate that the breach involves sensitive information that could be used for malicious purposes.

The types of data identified in the leaked samples include:

• Identity documents
• Official correspondence
• Personal data

The presence of such sensitive information highlights the potential severity of the breach for the individuals involved.

About the organization

The Association ouvrière des Compagnons du Devoir et du Tour de France is a non-profit organization located in France. The organization focuses on traditional craftsmanship and vocational training. It plays a significant role in supporting the professional development of young people by providing apprenticeship and master-level training across various trades.

Impact and organizational risks

This alleged leak may pose secondary risks such as identity theft and targeted phishing attacks for the organization's employees and members. When personal data and identity documents are exposed, malicious actors can use them to impersonate individuals or craft highly convincing social engineering campaigns. Such attacks can lead to further security compromises or financial fraud targeting the members of the association.

Given that the organization operates in France, the leaked data may fall under the scope of the European Union's General Data Protection Regulation (GDPR). This regulatory framework imposes strict requirements on how personal data is handled and protected. Consequently, the publication of this data could lead to reputational damage and potential legal sanctions for the organization.

The Qilin group is known for employing double extortion, and their actions may be an attempt to pressure the organization's operational continuity. For organizations in the education and vocational training sector, maintaining the integrity of member and student data is critical for trust and legal compliance. General defensive steps for organizations facing such threats often include implementing robust data encryption, maintaining offline backups, and conducting regular security awareness training to defend against phishing attempts.
