Casino heist in Monte Carlo: SBM lodges a complaint over cyber incident

In August 2025, Monte-Carlo Société des Bains de Mer (SBM) found itself at the centre of cybersecurity investigations following claims by the hacking group D4rk4rmy of a breach.

SBM promptly acknowledged the potential threat on August 3rd and launched investigations into all possible sources. The company confirmed that the alleged incident involved access to a very limited number of employee/customer contacts, but no confirmed breach had yet been verified at the time.

No intrusion or anomaly has been detected in SBM’s IT infrastructure, and no operational disruption occurred. The company promptly notified relevant Monegasque authorities and filed a formal complaint, maintaining transparency and cooperation during the ongoing investigation.

The Monaco Cybersecurity Agency (AMSN), the Data Protection Authority (APDP), and the Public Safety Directorate have been informed about the alleged cyberattack. They are actively collaborating with SBM in their investigations, focusing on the authenticity and origin of any potentially compromised data.

D4rk4rmy claimed to have hacked SBM and posted information on the dark web, but SBM’s internal teams continue to verify the authenticity and impact of these claims. The Monaco authorities are working diligently to verify and analyze the alleged cyberattack, with all competent teams fully mobilized.

Monte-Carlo Société des Bains de Mer is committed to transparency and will provide updates as more information becomes available about the alleged cyberattack. The company is actively engaged with all relevant authorities in the Principality of Monaco regarding the alleged cyberattack and its potential implications.

At this stage, no factual evidence of a cyberattack has been detected. The investigations are ongoing to confirm this and ensure the security and integrity of SBM's data and operations. Monte-Carlo Société des Bains de Mer has filed a complaint with all relevant authorities in the Principality of Monaco, demonstrating their commitment to addressing any potential threats to their systems and the data they safeguard.
