Caesars Entertainment, a leading resort chain with ownership of more than 50 hotels and casinos worldwide, officially disclosed a cyberattack on their systems. The U.S. Securities and Exchange Commission received notification on Thursday, indicating that the company has experienced a substantial loss of sensitive customer data due to the breach. In a recent development, Caesars Entertainment detected unusual activity within their IT network. 

According to the filed Form 8-K, this incident stemmed from a social engineering attack targeting an external IT vendor employed by the prominent hotel chain. After conducting an extensive internal inquiry, it was revealed that on September 7th, the database housing sensitive information of members in the Caesars Entertainment loyalty program, including details such as social security numbers and driver's license numbers, had been compromised. 

The company stated in its notice that they are currently in the process of probing the full scope of any supplementary personal or otherwise sensitive data obtained by the unauthorized party. At present, there is no indication to suggest that any personal banking or payment details were also accessed. The cyberattack has not affected the operations of physical properties, online platforms, or mobile gaming. 

These aspects continue to function seamlessly without any disruption. Caesars Entertainment has refrained from specifying the exact count of affected loyalty members, only indicating a "significant amount." As per Caesars' Informational website, the company maintains constant vigilance over the web, yet has found no trace of the compromised data being disseminated, disclosed, or put to any illicit use. 

While Caesars Entertainment has taken measures to initiate the erasure of the pilfered data, they are unable to provide an absolute assurance that it has been completely expunged, as stated in the notice. Concurrently, the company remains vigilant in its web monitoring efforts to ascertain whether the compromised data has been divulged or subjected to illicit utilization. 

As an extra precautionary measure, all members of the loyalty program will be extended credit monitoring and identity theft protection services. Caesars Entertainment intends to personally inform those affected in the ensuing weeks.
