- BWH Hotels confirmed a cyberattack on April 22, 2026, stealing customer names, emails, phone numbers, postal addresses, and reservation details
- Attackers exploited a flaw in a web app holding guest reservation data, but payment and bank details were not affected
- Company took the app offline, engaged external experts, and urged customers to stay vigilant against suspicious communications
BWH Hotels, a major global hospitality chain operating thousands of hotels around the world, has confirmed suffering a cyberattack and losing sensitive customer data.
In a data breach notification recently sent to affected individuals, the company’s Chief Technology Officer (CTO) Bill Ryan said the attack was spotted on April 22, 2026. The crooks stole sensitive data, including people’s names, email addresses, telephone numbers, and postal addresses, of a yet undetermined number of people.
Reservation details, including reservation numbers, dates of stay, and special requests, were also nabbed.
A warning to users
The data was generated between October 14, 2025, and April 22, 2026, but it was left unclear how long the crooks lurked within BWH Hotels’ systems.
The unnamed attackers apparently found a flaw in a web application that housed certain guest reservation data, but that information did not include payment or bank details.
“Upon discovering the incident, we immediately took the application offline and revoked the unauthorized access,” Ryan told The Register in a written statement.
“We have engaged leading external cybersecurity experts to support our incident response efforts and to assist with the further strengthening of existing safeguards.”
Ryan also urged its customers to be “extra vigilant” when viewing any unexpected or suspicious communications about hotel stays.
“If you receive a suspicious communication such as an unexpected email, text, WhatsApp message, or telephone call that asks for payment, codes, logins, or ‘verification,’ even if they reference a BWH Hotels property or an upcoming reservation, do not engage. Navigate to sites directly rather than clicking links,” he stressed.
BWH Hotels is a global hotel group that serves as the parent organization for Best Western Hotels & Resorts, WorldHotels, and SureStay Hotels. It operates roughly 4,300 hotels across more than 100 countries, and earns more than $8.5 billion annually.
