The Brain Cipher ransomware group claims they orchestrated a cyberattack on several French national museums, including the iconic Le Grand Palais, during the recent Olympic Games. They allege they have stolen 300GB of data and plan to leak it today. The attack targeted financial systems related to 40 institutions overseen by Réunion des Musées Nationaux – Grand Palais (RMN-GP). Despite these claims, no operational impact or confirmed data theft has been reported.
Brain Cipher, a new ransomware group, developed its malware using the leaked LockBit 3.0 builder, enhancing it with advanced code obfuscation techniques. These techniques complicate detection and analysis. French cybersecurity agencies have downplayed the impact on systems involved in the 2024 Olympic Games. The investigation continues, but details remain limited.
