MGM Resorts cyberattack to cost $100 million

MGM Resorts has admitted that the cyberattack it suffered in September will likely cost the company at least $100 million.

The effects of the attack are expected to make a substantial dent in the entertainment giant’s third-quarter earnings and still have a noticeable impact in its Q4 too, although this is predicted to be “minimal.”

According to an 8K filing with the Securities and Exchange Commission (SEC) on Thursday, MGM Resorts said less than $10 million has also been spent on “one-time expenses” such as legal and consultancy fees, and the cost of bringing in third-party experts to handle the incident response.

These are the current estimates for the total costs incurred by the attack, which took slot machines to the sword and borked MGM’s room-booking systems, among other things, but the company admitted the full scope of costs has yet to be determined.

The good news is that MGM expects its cyber insurance policy to cover the financial impact of the attack.

The company also expects to fill its rooms to near-normal levels starting this month. September’s occupancy levels took a hit – 88 percent full compared to 93 percent at the same time last year – but October’s occupancy is forecast to be down just 1 percent and November is poised to deliver record numbers thanks to the Las Vegas Formula 1 event.


MGM Resorts confirmed personal data belonging to customers had been stolen during the course of the intrusion. Those who became customers before March 2019 may be affected.

Stolen data includes social security numbers, driving license numbers, passport numbers, and contact details such as names, phone numbers, email addresses, postal addresses, as well as gender and dates of birth.

At this time, there is no evidence to suggest that financial information including bank numbers and cards were compromised, and passwords are also believed to be unaffected.


Adam Marrè, CISO at cybersecurity outfit Arctic Wolf, told The Register: “When looking at the total cost of a breach, such as the one which impacted MGM, many factors can be taken into account. This can include a combination of revenue lost for downtime, extra hours worked for remediation, tools that may have been purchased to deal with the issue, outside incident response help, setting up and operating a hotline for affected people, fixing affected equipment, purchasing credit monitoring, and sending physical letters to victims. Even hiring an outside PR firm to help with crisis messaging. When you add up everything, $100 million does not sounds like an unrealistic number for organization like MGM.
