Incident Details

Nevada Restaurant Services (NRS), the parent company of slot machine parlor chain Dotty’s, disclosed a data breach in September 2021 after identifying the presence of malware on certain computer systems in its environment. The intrusion occurred on or before January 16, 2021, meaning attackers had access for months before discovery. NRS determined that an unauthorized actor was able to copy certain information from its systems during this window.

Dotty’s operates approximately 175 slot machine parlor locations primarily in Nevada, and maintains a loyalty player database of roughly 300,000 customers. NRS did not specify the exact number of individuals whose data was exfiltrated. The breadth of data categories exposed was extensive: names, dates of birth, Social Security numbers, driver’s license or state ID numbers, passport numbers, financial account and routing numbers, health insurance information, medical treatment records, biometric data, taxpayer identification numbers, and credit card numbers with expiration dates. The inclusion of biometric data was particularly notable given the sensitivity and irreversibility of that category.

The disclosure in September 2021 came roughly eight months after the estimated breach date, raising questions about detection capabilities. NRS stated it had security measures in place and has worked to add further technical safeguards. Affected individuals were offered 12 months of complimentary credit monitoring and identity theft protection services through IDX.

The breach generated significant class action litigation. A $6.49 million class action settlement was subsequently reached to resolve claims arising from the incident. The case highlighted the particular sensitivity of biometric data held by gaming and hospitality operators who use fingerprint or facial recognition systems for loyalty programs, age verification, and payment processing in gaming environments.

This incident was not a traditional supply-chain compromise of a third-party vendor; rather, it was a direct malware attack against NRS’s own systems. The BlackKite “supply-chain” classification appears to stem from the fact that Dotty’s is a brand/subsidiary of NRS rather than a true third-party vendor breach.
