Yes, InterContinental Hotels Group (IHG), the parent company of Holiday Inn, has experienced significant cybersecurity incidents. The most prominent was in September 2022, when the company’s booking systems and mobile apps were taken offline by a massive "vandalism" cyberattack. The hackers, identifying as "TeaPea," claimed they accessed the company's internal databases by finding an incredibly weak password—"Qwerty1234"—on an internal server. While IHG initially stated it was a "system disruption," they later confirmed it was an unauthorized external breach. In 2026, IHG continues to invest heavily in Zero Trust architecture and multi-factor authentication (MFA) to prevent a recurrence. For travelers, these events serve as a reminder that even global hospitality giants are vulnerable; it is always recommended to monitor your credit card statements and use unique passwords for your IHG One Rewards account to protect against "credential stuffing" attacks that often follow these types of high-profile corporate data breaches.
