Some IHG Hotel Tech Systems Appear to Have Been Hacked

IHG (InterContinental Hotels Group), one of the world's largest hotel companies, issued a statement on Tuesday that said it was investigating unauthorized access to parts of the company's technology systems.

The UK-based company, which manages brands such as Holiday Inn and Crowne Plaza, said its "booking channels and other applications" had been disrupted since yesterday. It uses many external vendors, including Amadeus, to help with accepting reservations from third parties and other processes.

"IHG is working to fully restore all systems as soon as possible," the company said. "We will be supporting hotel owners and operators as part of our response to the ongoing service disruption. IHG's hotels are still able to operate and to take reservations directly."

IHG didn't say there had been any loss of customer data. Europe has strict laws that hold companies responsible for allowing customer data to be stolen by bad actors.
