University of Hawaiʻi Cancer Center Ransomware Attack and Data Breach
A ransomware attack on the University of Hawaiʻi Cancer Center's Epidemiology Division compromised the personal information of approximately 1.2 million individuals. The stolen data includes names, Social Security numbers, driver's license information, voter registration records, and health-related information. The incident was discovered on August 31, 2025, and affected servers supporting research operations, though clinical operations, patient care, and student records were not impacted. The university engaged with the threat actors and paid a ransom to obtain decryption tools and assurances of data destruction. Notifications to affected individuals were delayed until early 2026.
