The Black Basta ransomware group has listed the domain dupont-restauration.fr on its dedicated leak site. According to the group's announcement, they claim to have acquired a significant volume of data belonging to the organization, totaling 540 GB. This announcement, made on January 23, 2024, suggests a major security incident involving the French catering provider.

Details of the alleged attack and data theft

To support their claims, the group has released partial samples of the stolen data. These samples include structural examples of file directories, which provide a glimpse into the organization's internal file management.

The group asserts that the compromised information is not limited to a single category but spans several critical areas of the organization's operations. The data allegedly includes sensitive records that could impact both the company's financial standing and its internal administration.

About Dupont Restauration

Dupont Restauration is a France-based company specializing in the hospitality sector. The organization provides collective catering and food services, offering various dining solutions. Their services are directed toward a wide range of clients, including public institutions, schools, and private businesses.
