Silicon reports that the identities of more than 50,000 customers of major Bahamas resort Atlantis have been exposed to possible identity fraud following the theft of personal information from the hotel, the owners said.
Information stolen included names, addresses, credit card details, Social Security numbers, driver's licence numbers and bank account data, the filing said.
The information appears to have gone missing from the hotel's computer database and was the work of either an insider or an outside hacker.
The Atlantis hotel management is notifying affected customers in writing so they can take steps to protect themselves from possible identify fraud.
Atlantis is one of the world's landmark resort destinations. Thousands of tourists - mainly Americans - flock there every week to enjoy its casino and beachfront attractions.
It employs more than 5,000 Bahamians and is a major player in the country's economy.
