Grand Cercle, Poker Bowl

Grand Cercle and Poker Bowl operate as casino establishments in Aix-les-Bains, France, providing gaming and entertainment services to patrons. Their offerings include slot machines and other casino-related amenities, supported by backend server infrastructure critical to daily operations. The venues serve local and tourist markets within the Savoie region, functioning as leisure destinations with integrated digital systems for transactional and operational management. These facilities rely on uninterrupted technical functionality to maintain customer access to gaming platforms and ancillary services.

In July 2024, both casinos faced severe operational disruption following a ransomware attack that encrypted server data, forcing a full temporary closure. Management implemented immediate containment protocols to prevent lateral movement of the threat, enabling a partial reopening focused on reactivating slot machines while other services remained offline. The incident caused significant financial losses due to interrupted operations and recovery expenditures. Criminal proceedings were initiated through France’s Office de lutte contre la cybercriminalité (Ofac), with Paris prosecutors overseeing the investigation into the attack’s origins and perpetrators.

The establishments demonstrated incident response capabilities through containment actions and coordination with law enforcement, though the successful encryption of servers suggests vulnerabilities in their cybersecurity posture. No historical incidents or additional operational specialties beyond standard casino services are documented in available reports. Recovery efforts continued beyond the initial reopening phase to restore full functionality, reflecting persistent technical challenges stemming from the attack. Management publicly emphasized compliance with legal protocols through their criminal complaint while working to mitigate long-term reputational and operational impacts.
