last month that MGM Resorts is calling a cyberattack is expected to cost the casino giant more than $100 million, the Las Vegas-based company said.
The incident bore all the hallmarks of an extortionary ransomware attack, which MGM has not confirmed. If so, it could be the costliest ransomware attack on record, said Brett Callow of the cybersecurity firm Emsisoft. In 2019, the Norwegian aluminum manufacturer Norsk Hydro suffered $70 million in losses after refusing to pay ransomware criminals.
MGM has no evidence that the hackers and criminals have used the data to commit account fraud or identity theft, Hornbuckel said, noting the company will also reach out to impacted consumers via email and offer free identity protection and credit monitoring services.
MGM wasn't the only casino giant to get hit by hackers last month. Caesars Entertainment disclosed a Sept. 7 cyberattack. The Reno-based company said that its casino and online operations were not disrupted.
