The Las Vegas MGM Cyber Attack
The MGM Cyber Attack in Las Vegas was a significant cybersecurity incident that affected MGM Resorts International, a major gaming and entertainment conglomerate. The attack on MGM was reported on September 11, 2023, when the company disclosed a "cybersecurity issue" impacting some of its U.S. systems.
Scattered Spider, an affiliate of the ransomware-as-a-service group BlackCat (ALPHV), claimed responsibility for the breach. Using social engineering tactics, the group infiltrated MGM's computer systems, prompting a 10-day shutdown of affected systems to protect data. The incident disrupted operations at major MGM hotels, including the Bellagio, and resulted in the theft of approximately 6 terabytes of data.
The company estimates a negative impact of about $100 million on Adjusted Property EBITDAR for Las Vegas Strip Resorts and Regional Operations. An additional $10 million was lost due to risk remediation, legal fees, and incident response measures.
The MGM cyberattack compromised personal information, including names, contact details, driver's license numbers, Social Security numbers, and passport numbers for some customers who had transacted with MGM before March 2019, though no bank account or payment card information was accessed. MGM refused to pay the ransom and instead provided free credit monitoring services and loyalty rewards to affected customers.
By October 5, CEO Bill Hornbuckle announced that most MGM systems were back online and the attack was contained. The FBI is investigating the incident, which led to a more than 6% drop in MGM's share price and federal lawsuits against the company.
This incident highlights the vulnerability of large corporations to ransomware attacks and the importance of robust cybersecurity measures, especially against social engineering tactics.
