Cyberattack Disrupts Online Reservations for Thousands of European Cultural Sites In early March, a ransomware attack targeting Irec SAS, the French subsidiary of online ticketing platform Vivaticket, disrupted online reservations for nearly 3,500 museums, monuments, and cultural sites across Europe. The RansomHouse ransomware operation claimed responsibility, listing Irec on its leak site and asserting that stolen data included full names, purchase histories, reservation details, email addresses, login timestamps, account metadata, and countries of residence. Among the affected sites were high-profile landmarks such as the Musée du Louvre, Musée d’Orsay, Arc de Triomphe, Eiffel Tower, and Notre-Dame de Paris. While Vivaticket confirmed no credit card or banking details were accessed, some ticketing services and organizational platforms remain unavailable. The French National Cyber Security Directorate (ANSSI) and law enforcement are investigating the breach alongside Vivaticket to assess its full scope. The French Ministry of Culture stated that impacted institutions are still evaluating the financial and operational toll of the attack. Customers have been notified of the breach as authorities work to contain the fallout.
