Changhua Christian Hospital Listed by Crazyhunter Ransomware Group

On March 5, 2025, Taiwan’s Changhua Christian Hospital appeared on the leak site of the ransomware group known as crazyhunter. The listing indicates that internal files were exfiltrated during a ransomware attack, although the precise number of records and the full scope of exposed data remain unclear from public reporting.

Reported Details of the Incident

Public reporting indicates the hospital was listed on the crazyhunter leak portal hosted on the dark web. The entry states that attackers successfully exfiltrated internal files before encrypting systems. No specific patient count or detailed data inventory has been released by the hospital or independently verified. Available reporting describes the incident as a classic ransomware double-extortion case in which data is stolen and then threatened with publication unless a ransom is paid.

March 5, 2025 marks the date the hospital’s name was published on the group’s leak site. The exposed material is described only as “internal files,” leaving patients, staff, and their families uncertain about whether names, medical records, insurance details, or contact information were taken.

Why This Matters for You and Your Family

When a hospital’s internal systems are breached, the information at risk often includes the personal details of ordinary families who sought care. Medical records can contain addresses, phone numbers, dates of birth, Social Security or national ID numbers, and clinical history. Once stolen, these records can be sold, published, or used to launch further attacks against you or your relatives. Even if you were not treated at Changhua Christian Hospital, similar attacks happen regularly at healthcare providers worldwide, meaning your family’s health data could be next.
