Omni Hotels & Resorts has told customers that the recent disruptions have been caused by a cyberattack that forced it to shut down some systems.
The Texas-based Omni Hotels & Resorts runs 50 upscale hotels and resorts across North America, offering more than 23,000 rooms. According to its website, it has roughly 14,000 employees.
In a notice on its website, the company said it started responding to a cyberattack on March 29.
“Upon learning of this issue, Omni immediately took steps to shut down its systems to protect and contain its data,” the hotel chain said.
“We are currently working to determine the scope of the event, including impact to any data or information maintained on Omni systems. Our investigation into the incident remains ongoing and we are working with external specialists in this process,” it added.
The hotel said most of the systems that were taken offline in response to the attack have been brought back online. Its website is currently working and reservations can be made online.
Customers who had been staying at Omni hotels when the incident started reported check-ins being done on paper, room keys not working, and being unable to pay with credit cards.
The disruption may be the result of a ransomware attack, but no known cybercrime group appears to have taken credit for it.
SecurityWeek has reached out to Omni Hotels to find out whether this was a ransomware attack, but the company referred us to the notice on its website.
