Cyberattack at Intercontinental Hotel Group (IHG) disrupts Franchisees, Customers and Supply Chains

March 24, 2023


Leading hospitality company InterContinental Hotels Group says its IT systems have been disrupted after its network was breached. Customers reported widespread problems with booking and check-in. "Booking channels and other applications have been significantly disrupted since yesterday," IHG said in an official notice lodged with the London Stock Exchange.

The attack disrupted business at franchisees during September, leaving a trail of angry customers, lost income and a class-action lawsuit. The hack on the hotel group highlights the potential ripple effects for franchisees, customers and supply chains, reports the WSJ.

The hotel chain giant was also the target of a three-month security breach in 2017—between September 29 to December 29—when more than 1,200 InterContinental franchised hotels in the United States were impacted. An IHG spokesperson denied commenting when contacted by BleepingComputer earlier today, saying that "outside of the statement, we don't have any more that we can say at the moment."
