The central data systems of Paris' Grand Palais and other museums in the Réunion des Musées Nationaux (RMN) network were targeted by a ransomware attack, according to the Paris prosecutor's office. Despite the attack, which was detected on Sunday and affected around 40 museums across France, there have been no disruptions to the Summer Olympics events hosted at some of these venues.

The Grand Palais-RMN network confirmed that no data extraction has been detected so far. Their technical teams are fully engaged in resolving the issue as efficiently as possible.

The Grand Palais is currently hosting fencing and taekwondo competitions, while the Château de Versailles, also part of the RMN network, is the venue for equestrian sports and the modern pentathlon.

The Paris prosecutor's office has tasked the Brigade for Combating Cybercrime with investigating the attack to identify its scope and perpetrators. Efforts are ongoing to secure and restore the compromised systems.
