MGM Resorts Refused to Pay Ransom to Attack That Cost It $100 Million

MGM Resorts International refused to pay a hackers’ ransom demand in a September cyberattack that threw its Las Vegas Strip resorts into chaos and crippled its properties and technology nationwide, according to a person familiar with the matter. Service disruptions from the attack and efforts to resolve the issue will cost the company more than $100 million in the third quarter, MGM said in a regulatory filing Thursday.
