Brain Cipher ransomware group claims responsibility for a cyberattack on French national museums during the Olympic Games. They threaten to leak 300 GB of data and have a history of targeting institutions. The group’s ransomware appears more advanced, utilizing code obfuscation techniques. Despite this, experts believe robust defenses may detect and quarantine their attacks.
The meeting notes highlighted a significant cyberattack on French national museums by the Brain Cipher ransomware group, resulting in a claimed theft of 300 GB of data. The attack targeted a system used to centralize financial data of roughly 40 institutions under Réunion des Musées Nationaux – Grand Palais (RMN-GP). Despite limited official information on the data nature and police probe, it is known that the affected institutions are recovering and that cybersecurity agencies were informed. The cybercriminal group evolved from the leaked LockBit 3.0 builder and uses advanced code obfuscation techniques, challenging analysis and detection. Their communication domain and tactics resemble those of other new groups such as Risen and SenSayQ, and their cyberfear[.]com domain serves as a platform for communication with victims.
