Booking.com contacts customers on possible data breach

Irish-based customers of Booking.com are among those that have been contacted by the reservations website about a potential data breach.

In an email to customers, seen by RTÉ News, the company states that "unauthorised third parties may have been able to access certain booking information associated with your reservation".

Booking.com said it recently noticed suspicious activity affecting a number of reservations and it immediately took action to contain the issue.

It goes on to explain how updated PIN numbers have been issued to keep bookings secure.

"If you have received suspicious emails or phone calls, these could be from malicious actors pretending to represent the accommodation or Booking.com," according to the email.

"We'll never ask you to make a bank transfer that is different from the payment policy details in your booking confirmation," it added.

The email urges customers to remain vigilant before clicking on any links.
