It went on to say that its operations have been disrupted since Monday, which has left people struggle to reserve rooms online, at least.

Firm officials reported in the statement they are putting its response plans in motion, notifying authorities about the intrusion, and working with its technology suppliers. In addition, experts from outside of IHG also are being brought in to help with the investigation:

IHG is working to fully restore all systems as soon as possible and to assess the nature, extent and impact of the incident.

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.
