Ransomware group Brain Cipher takes responsibility for cyberattack on French National Museum

Ransomware group Brain Cipher has claimed responsibility for a cyberattack on dozens of French national museums during the Olympic Games earlier this month. The group has said it will leak 300GB of stolen data, but has not revealed the nature of the information.

Institutions overseen by Réunion des Musées Nationaux – Grand Palais (RMN-GP) were the target of an attack that reportedly saw data stolen from the system the organisation used to “centralise financial data”.
