Cruise operator Carnival Corp disclosed, it has launched an investigation into a ransomware attack on one of its brand’s computer network systems.

In a regulatory filing, Carnival, which operates AIDA, Carnival and Princess cruises among others, disclosed that through the attack hackers were able to gain access personal data of guests and employees.

Carnival Corp did not identify the brand that faced the cyber attack, and declined to provide more details, given that the investigation was at an early stage.

The cyberattack compounds headwinds facing the struggling company which is weighed down by COVID-19 induced suspension of cruises midst a global travel restriction.

Hackers had managed to downloaded certain data files during the attack, said Carnival and that there were no assurances that information technology systems of its other brands will not be adversely affected.

Ransomware is a kind of malicious program used by hackers to take over control of files in an infected system following which they demand hefty payments to recover them.

Carnival said, it believes the security incident will not materially impact its business, operations or financial results.
