On Wednesday, a group known as BlackCat took credit for the attack, saying a 10-minute phone call was responsible for compromising the resort’s systems. MGM Resorts International is the largest casino operator — with 10 resorts — on the Las Vegas Strip.

The attack continues to impact the company’s website, reservation systems, and some gaming machines and has left guests frustrated.
