Executive Summary
In summer 2019, a cloud server holding MGM Resorts guest information was accessed, and about 10.6 million guest records (roughly 3.1 million unique email addresses) were later published on a hacker forum in February 2020. Exposed data included names, email and physical addresses, phone numbers, and dates of birth for former hotel guests.
ObscureIQ assessment: Severe risk of phishing, loyalty abuse, fraud, and physical-world targeting. Casino and resort data may also reveal travel patterns, spending behavior, and VIP status.
Breach Impact
The pairing of names, home addresses, phone numbers, and dates of birth supports identity fraud and targeted phishing; the guest context can also reveal travel patterns.
