- Booking.com is warning users about data breaches affecting booking details
- Exposed information includes names, e-mails, addresses and telephone numbers
- The company reset PINs, warning of phishing attacks targeting recent bookings
Booking.com is notifying some of its users of a data breach that may have leaked their personal information.
Platform users contacted TechRadar Pro to say they received warning emails from the platform, with one saying: “I was sent this email 12 hours ago from booking.com (twice – for 2 different bookings).”
In its email, the company said it recently noticed suspicious activity “affecting a number of reservations,” prompting an investigation. “Based on the results, the information available may include booking details, names, emails, addresses, phone numbers and anything else you may have shared with the property.”

“To keep your reservation secure, we have updated the PIN on your reservation,” it concluded, warning users of possible phishing attacks in the near future.
However, attacks seem to have already started happening, as one user told TechCrunch they received a message via WhatsApp which included “order details and personal information.”
The user later told TechRadar Pro that they received three emails from the platform, all for bookings made in the past week, and speculated that the information related to recent bookings rather than entire accounts.
They confirmed to be a “standard customer” booking accommodation via the web interface.
According to some sources, Booking is the most visited travel website in the world with more than 560 million visits per month globally. The platform offers accommodation listings in more than 220 countries and territories and provides access to millions of properties, including hotels, homes, apartments and other accommodation types.
Its popularity also makes it a major target for cybercriminals, who often manage to find their way inside. In mid-January 2026, for example, there was news of “hundreds of Dutch travelers” being defrauded when hackers managed to hijack their accounts.
