In a series of recent cybersecurity incidents, venues for the 2024 Paris Olympics and numerous French museum shops have fallen victim to a hacking group. Allegedly, the hackers exploited data processing systems from around 40 tourist sites to successfully infiltrate and gather significant financial information. Affected venues include the famous Louvre Museum, with its daily operations and finances significantly impacted. In response to this threat, the hacking group has made it clear that unless the respective institutions pay a specific amount in cryptocurrency as ransom, they will either leak or destroy the obtained information, leading to broader economic loss and societal impact. French police have swiftly reacted by establishing a dedicated anti-cybercrime unit (BL2C) for investigation. Currently, the investigation is ongoing, aiming to track down the hackers' activities and take necessary measures to protect the safety of affected institutions. Meanwhile, experts advise the public to remain vigilant and strengthen their cybersecurity measures to prevent similar occurrences. This event underscores the severity of global cyber attacks and their potential threats to critical infrastructure.
