RansomHub ransomware group lists www.citebd.org on its leak site

• Ransomware group: RansomHub
• Country: France
• Sector: Professional Services
• Announcement date: August 30, 2024

The RansomHub ransomware group has listed the French cultural institution www.citebd.org on its dedicated leak site. According to the threat actor, the organization has been targeted in a data breach, with the group claiming to have obtained a significant volume of sensitive information belonging to the entity.

The claims made by RansomHub

The threat actor added the domain www.citebd.org to their leak portal on August 30, 2024. In the announcement, the group issued a threat, stating that if the organization does not contact them, they will proceed to publish the data they claim to possess. The group asserts that the volume of the stolen information totals 1.7 TB.

As part of this public announcement, the group has shared several sample files intended to demonstrate the nature of the breach. These samples are used by ransomware groups as a tactic in double extortion schemes, where attackers not only encrypt an organization's systems but also threaten to release stolen data to pressure the victim into paying a ransom. By publishing these samples, the group aims to prove the validity of their claims and increase the pressure on the target organization.

Details of the alleged data breach

While there is no definitive information regarding the full scope of the leaked data, the shared samples provide some insight into the potential contents of the breach. The file names visible in the screenshots provided by the group appear to be related to the institution's operational processes. Specifically, the samples suggest that the stolen information may include:

• Financial records
• Payment documents

The presence of these file names indicates that administrative and financial records of the institution may be at risk. While the exact total count of files has not been disclosed, the sheer volume of the claimed data suggests a broad impact on the organization's digital assets.

About La Cité Internationale de la Bande Dessinée et de l'Image

La Cité Internationale de la Bande Dessinée et de l'Image is a cultural institution located in Angoulême, France. The organization is dedicated to the promotion of comics and visual arts. It serves as a multifaceted hub for the community, hosting various exhibitions, workshops, and educational programs. Additionally, the institution features a museum, a library, and a cinema, making it a significant center for cultural engagement in the region.

Analysis and potential implications

Given that the institution functions as a cultural center, the leaked data may contain personal information belonging to employees or records related to visitors. This possibility introduces significant risks regarding data privacy. Since the organization is based in France, such a breach could lead to legal sanctions under the General Data Protection Regulation (GDPR), which is currently in effect in the country.

The shared samples indicate that financial data may be at risk, which could create secondary risks for the institution, such as fraud or identity theft. Furthermore, the publication of this data could create a basis for targeted phishing attacks against the organization or its stakeholders. RansomHub, the group responsible for this listing, is a Ransomware-as-a-Service (RaaS) group that emerged in early 2024 and is believed to have ties to ALPHV. It has been reported that their operations ceased in early 2025.

For organizations in the professional services and cultural sectors, such incidents highlight the importance of robust cybersecurity frameworks. To mitigate these risks, organizations typically focus on implementing strong access controls, maintaining regular offline backups, and conducting employee training to recognize phishing attempts. Protecting sensitive financial and personal data is essential to avoid the legal and reputational consequences that follow a public data leak.
