The hospitality conglomerate, InterContinental Hotel Group (IHG) manages 17 hotel chains, including the Regent, Crowne Plaza, Holiday Inn, and Candlewood Suites. IHG operates 6,028 hotels in more than 100 different countries.

The company announced that the Holiday Inn Hotel subsidiary of IHG suffered a cyberattack, attackers has access to parts of the company’s technology systems.

The attack significantly disrupted IHG’s booking channels and other applicationsì, a circumstance that suggests that the company was the victim of a ransomware attack. The security breach also impacted the booking process through third-party sites such as Expedia and Booking.com, and the service was intermittently resumed during this week.

“InterContinental Hotels Group PLC (IHG or the Company) reports that parts of the Company’s technology systems have been subject to unauthorised activity.” reads a statement published by the company. “IHG has implemented its response plans, is notifying relevant regulatory authorities and is working closely with its technology suppliers. External specialists have also been engaged to investigate the incident.”

IHG is working to restore its operations and determine the extent and impact of the incident.

The Post reported that some franchisees told them that significant disruptions continued to make the system unavailable as of early Friday.

“Customers who are trying to book rooms can only log onto Holiday Inn’s site and make reservations about half the time, according to Vimal Patel, a franchisee who operates Holiday Inn Express hotels in LaPlace, La. and Donaldsville.” reported The Post.
