Booking.com warned customers that unauthorized parties accessed personal information linked to some reservations, exposing data that may include booking details, names, email addresses, physical addresses, phone numbers, and information shared with accommodations. The company said it detected suspicious activity, contained the incident, changed reservation PINs, and notified affected guests, while stating that payment or other financial information was not accessed from its systems. Booking.com did not disclose how many customers were affected.
The breach was disclosed amid broader fraud and cybercrime pressure on the travel platform, including phishing and impersonation scams targeting Booking.com users. Reporting also highlighted rising consumer complaints and scam losses tied to travel-booking fraud, as well as scrutiny from an earlier Booking.com incident in which phishing against hotel staff exposed data from more than 4,000 people and later resulted in a €475,000 regulatory fine after delayed breach reporting in the Netherlands.
