The company said in a statement on its website that it was working with credit card companies, law enforcement and forensic experts as it investigates the matter. It also said that it had implemented "additional security measures" at all of its hotels.
The full statement is available here.
Oriental can confirm that the credit card systems in an isolated number of our hotels in the US and Europe have been accessed without authorization and in violation of both civil and criminal law. The Group has identified and removed malware and is coordinating with credit card agencies, law enforcement authorities and forensic specialists to ensure that all necessary steps are taken to fully protect our guests and our systems across our portfolio. We take the protection of customer information very seriously. Unfortunately incidents of this nature are increasingly becoming an industry-wide concern and we have therefore also alerted our technology peers in the hospitality industry.
