Booking.com says hackers accessed customer reservation data in a breach that may have exposed booking details, names, email addresses, phone numbers, addresses, and messages shared with accommodations. PCMag reports: On Sunday, users reported receiving emails from Booking.com, warning them that "unauthorized third parties may have been able to access certain booking information associated with your reservation." The email suggests the hackers have already exploited customer information. "We recently noticed suspicious activity affecting a number of reservations, and we immediately took action to contain the issue," Booking.com wrote. "Based on the findings of our investigation to date, accessed information could include booking details and name(s), emails, addresses, phone numbers associated with the booking, and anything that you may have shared with the accommodation." Amsterdam-based Booking.com has now generated new PINs for customer reservations to prevent hackers from accessing them.

The Australian Broadcasting Corporation and several Reddit users say they received scam messages from accounts posing as Booking.com.Read more of this story at Slashdot.
