MGM Resorts International announced it was the victim of a ransomware attack last month that may have compromised the personal information of customers who visited its hotels and casinos before March 2019.
The company declined to pay the ransom demanded by hackers and has been working to restore affected systems across its properties. While MGM says financial data was not accessed, information including names, contact details, dates of birth, driver’s license numbers, and some passport numbers may have been stolen.
Limited Social Security Numbers Also Exposed
According to MGM, according to MGM, aa limited number of impacted customers also had social security numbers accessed by the attackers. The company has not clarified precisely how many guests were affected overall.
MGM Resorts operates significant hotel and casino properties in Las Vegas, Detroit, Mississippi, Maryland, Massachusetts, and other states. The company says its domestic operations have returned to normal, but work is still being done to restore some guest-facing systems fully.
Consulting, legal fees, and other advisor costs related to the cyber attack are estimated to total around $10 million. MGM expects the overall financial impact to reach approximately $100 million.
