Carnival Corporation, the world’s largest cruise line operator, disclosed that one of its brands suffered a ransomware attack involving unauthorized access and encryption of data.
According to an 8-K form submitted to the Securities and Exchange Commission (SEC), the attack took place on August 15, 2020.
“Carnival Corporation and Carnival plc detected a ransomware attack that accessed and encrypted a portion of one brand’s information technology systems,” the company said. “The unauthorized access also included the download of certain of our data files.”
Following the security incident, Carnival announced an internal investigation, and notified law enforcement. They also engaged the services of third-party cybersecurity professionals, and “implemented a series of containment and remediation measures to address this situation and reinforce the security of its information technology systems.”
“The Company is working with industry-leading cybersecurity firms to immediately respond to the threat, defend the Company’s information technology systems, and conduct remediation,” Carnival added.
Although its initial assessment revealed the incident affected just a portion of a brand’s network systems, the report lacked details regarding the type of compromised information and the extent of the incident. However, the company “does not believe the incident will have a material impact on its business, operations or financial results.”
Despite this preliminary report, Carnival expects claims from its guests, employees and shareholders, revealing that the attack may have included unauthorized access to personal data of customers and employees.
“Nonetheless, we expect that the security event included unauthorized access to personal data of guests and employees, which may result in potential claims from guests, employees, shareholders, or regulatory agencies,” the filing reads. “Although we believe that no other information technology systems of the other Company’s brands have been impacted by this incident based upon our investigation to date, there can be no assurance that other information technology systems of the other Company’s brands will not be adversely affected.”
The cruise operator gave no additional information, such as the name of the impacted brand or type of ransomware used to encrypt its network.
