Breach Summary
In September 2023 MGM Resorts was breached by Scattered Spider, who used help-desk social engineering to gain access and disrupt operations. A circulating dataset of roughly 25 million guests included names, contact details, dates of birth and, for some, driver's license and passport numbers and SSNs.

About MGM Resorts
MGM Resorts International is a US-based hospitality and gaming company operating casino resorts and entertainment venues, primarily in Las Vegas and regional US markets, serving tens of millions of guests through its properties and loyalty program.
Why They Hold Your Data
A casino and hotel operator typically holds guest identity and contact details, dates of birth, loyalty-program records, and for a subset of guests government identifiers and payment information collected at booking and check-in.
Recent Developments
MGM continues to operate at scale. The September 2023 intrusion caused a multi-day operational outage across properties and became a defining example of help-desk social engineering; the company later disclosed regulatory and litigation costs.

Breach Impact
The incident forced a multi-day shutdown of hotel and casino systems, drew regulatory scrutiny and class litigation, and became a reference case for MFA-bypass and help-desk vishing across the industry.
Principal Risk Advisory
What this means for a principal
A travel or hospitality breach: itinerary, loyalty and contact data supports pattern-of-life inference and travel-themed phishing. For a high-profile principal this is targeting-grade, not merely identity-theft-grade: the combination lets an adversary locate, impersonate, or pressure the principal with little additional work.
What You Should Do
- Freeze credit at all three bureaus and monitor for new-account and tax-refund fraud.
- Treat the home address as exposed: review mail and package handling and physical-security routines, and brief household staff to verify unusual requests.
- Guard against SIM-swap and vishing: add a carrier port-out PIN and verify any 'support' calls independently.
- Do not use unofficial 'am I affected' lookups; several are themselves harvesting operations.
How ObscureIQ Can Help
- Corpus confirmation: determine whether and where the principal (plus household and staff) appear in this dataset and which specific fields are exposed for them.
- Exposure mapping and footprint neutralization: cross-reference against broker-available data and suppress still-removable elements, prioritizing address and phone, since this record re-seeds broker networks.
- ThreatWatch tuned to this incident's identifiers and misuse pattern (impersonation and targeting patterns, not generic credential monitoring).
