Carnival Corporation, the world's largest cruise company, confirmed that hackers accessed a portion of one brand's IT systems and downloaded data files during a ransomware attack.
The breach affected multiple brands under the Carnival umbrella and highlighted the complex cybersecurity challenges facing large organisations with distributed IT environments spanning vessels, ports, and corporate networks.
Robust endpoint detection, network segmentation, and tested recovery procedures are essential defences for organisations managing large interconnected systems across geographically dispersed operations.
