While the intrusion was detected on **March 19th**, the company assessed that the **likelihood of misuse of the stolen data was low**. This incident was part of a recurring pattern, as Carnival Corp. had endured **multiple ransomware attacks over a two-year period**, highlighting persistent vulnerabilities in its cybersecurity defenses.
