How many

  • Patients 83,007 people

Who is affected

  • Patients

Cause

An internal hard drive removed from a testing device and awaiting disposal went missing from a locked storage room

Timeline

  1. Data on the drive spans December 15, 1998 to December 27, 2023
  2. Detected
  3. First disclosure

Response

  • Data deleted
  • Governance / committee

From now on, media containing personal data will be physically destroyed inside the hospital and disposed of only after several staff confirm the data can no longer be read

What you should do

  1. Health data can't be taken back. Don't answer blackmail; call the police (#9110) or the consumer hotline (188)
  2. Check the company's notice to see if you're affected

Lessons for companies

  1. Report to the PPC: preliminary in 3–5 days, final in 30 (60 if malicious)
  2. Run red teaming and AI-assisted hardening, and publish how much you invest
