Have I Been Pwned flagged 7.5 million email addresses from Holland America Line's Mariner Society loyalty program. ShinyHunters published the data after ransom talks failed, claiming to hold terabytes of corporate data. Carnival says a phishing attack affected a single user account, but the scope of the breach remains unclear. Exposed data includes names, birth dates, and membership details.
