Carnival Cruise data breach leaks personal information of customers and employees

Carnival Corp. said Thursday that a data breach in March might have exposed personal information about customers and employees on Carnival Cruise Line, Holland America Line and Princess Cruises. The breach makes Carnival the latest in a string of large companies to be hit by hackers this year, including McDonald's, JBS meatpacking and Colonial Pipeline.

In a letter to customers, the company indicated that outsiders might have gained access to Social Security numbers, passport numbers, dates of birth, addresses and health information of people. The company declined to say how many people's information was exposed.
