MGM Resorts International has filed financial disclosures asserting that the company has suffered approximately $100 million in lost revenue due to the extortion-based cyberattack launched against MGM last month.

The attack, which began on September 11, crippled operations at most MGM Resorts while affecting most major computerized systems. MGM took some systems offline voluntarily as it began investigating the extent of the attack and accompaning theft of customer data.

Most MGM venues experienced long wait lines as hotel-registration systems were forced offline. The affected and often interconnected systems ran the gamut of most venues' operations and services, including ATMs, computerized room keys, parking-ramp access, digitally-banked slots and other jackpot games, credit-card processing, and much more.

MGM properties offering poker suffered impacted services in that area as well, since reservation systems and loyalty-program connections were also forced online. A couple of venues shuttered their poker rooms briefly following the attack's onset.
