In April 2026, the hacking group ShinyHunters claimed to have breached Carnival Corporation, exposing 8.7 million records, including 7.5 million unique email addresses tied to the Mariner Society loyalty program of Holland America Line. The leaked data contains personal information such as names, dates of birth, genders, and membership status. Carnival acknowledged a phishing attack that compromised a single user account but downplayed the incident's scope. ShinyHunters, known for extortion tactics, published the data after negotiations with Carnival reportedly failed. The breach raises concerns about potential phishing and fraud targeting affected individuals. The company is currently investigating the incident and has not confirmed the full extent of the data accessed. Security experts advise affected customers to be vigilant about their email security.
