100+ European Hotels Hit by Reservation Data Breach

A data breach affecting reservation management software used by more than 100 hotels, primarily in the Netherlands and with reported incidents in Belgium and Ireland, has exposed the personal and booking information of thousands of guests. The compromised data, which includes names, contact details, and reservation specifics, is now fueling phishing campaigns that impersonate the hotels and demand payments from travelers. Public reporting indicates that hundreds of guests have already been targeted, resulting in confirmed financial losses.

According to available reporting, the breach stemmed from a vulnerability in the hotels’ reservation management platform rather than individual hotel networks. The exposed information enables attackers to craft convincing messages that reference specific booking details, increasing the credibility of fraudulent payment requests. Industry research from sources such as DoxxScan™ continuous monitoring indicates that hospitality-sector breaches frequently involve contact and itinerary data that retain value for months or years after the initial incident. The breach was disclosed on June 4, 2026, with the affected properties spanning independent hotels and small chains rather than major global brands.
