Casino operator MGM Resorts International (NYSE:MGM) expects to face a US$100 million hit from a cyberattack that shut down its computers for 10 days last month.
Las Vegas-based MGM updated on Thursday that the attack would incur the hefty hit to its third-quarter results, with a "minimal" impact on its fourth quarter.
As work continues on restoring the system in the wake of the attack, which saw the theft of private data of customers who used MGM’s services before March 2019, the company tipped this could be as much as US$100 million.
However, MGM added in a statement that “the full scope of the costs and related impacts of this issue has not been determined”.
“We also believe a more limited number of social security numbers and passport numbers were obtained,” the group said.
“We have no evidence that the criminal actors have used this data to commit identity theft or account fraud.”
It is unclear whether the hackers approached MGM for any ransom, with an FBI investigation into the attack underway.
According to MGM, “virtually all” of its systems are back up and running after images of error messages on slot machines in its Las Vegas hotels circulated last month.
