The company said it was in the process of reaching out to individuals whose personal data may have been compromised in a recent cybersecurity incident.
Carnival announced the breach in a news release dated May 27 and said it was sending notification letters to anyone impacted by the April 2026 incident.
The total number of people impacted by the attack is estimated at 5,995,277, according to a data breach notice on the Maine attorney general’s website.
The notice states that the breach occurred on April 10 and was discovered several days later, on April 14.
Carnival said the company’s IT security system identified what it called unauthorized activity involving an employee’s account. The company determined the account was compromised by social engineering, which is a method that involves a person being tricked into turning over security information or gaining account access.

Carnival said the hacker only gained access to a “limited portion” of the company’s IT system.
The company said its investigation was ongoing, but personal information that is believed to have been compromised includes the following:
- Name
- Address
- Email address
- Phone number
- Date of birth
- Government-issued ID numbers, such as a driver’s license or passport number
Carnival said it was offering individuals in the U.S. two years of complimentary credit monitoring through its preferred third-party vendor, TransUnion.
Carnival has pledged to take steps to “further safeguard its systems” and enhance its security and monitoring controls.
Individuals who may have been impacted are encouraged to enroll in the credit monitoring services, which will be provided at no charge, and to report to local police if they believe they were the victim of identity theft or fraud.
