A cyberattack on InterContinental Hotels Group PLC disrupted business at franchisees this month, leaving a trail of angry customers, lost income and a class-action lawsuit. Hotel owners complain they received one email from IHG executives explaining that the attack would shut down online reservation systems. We remain focused on supporting our hotels and owners and throughout this period have communicated regular updates to owners and hotel teams,” an IHG Hotels & Resorts spokesperson said. Hotel owners said they dealt with angry customers whose reservations were lost due to the cyberattack. IHG franchisees pay monthly fees to use the company’s reservation technology, the lawsuit says.
