Ransomware group Brain Cipher have taken responsibility for a cyberattack on dozens of French National Museums during the Olympic Games earlier this month. The group have said they will leak 300 GB of stolen data, but have revealed nothing about the nature of the information.

Institutions overseen by Réunion des Musées Nationaux – Grand Palais (RMN-GP) were targeted by an attack which allegedly stole data from the system used by the organization to ‘centralize financial data’.
