What happened

Nine servers at Kamalnayan Bajaj Hospital were compromised in an overnight attack; data was encrypted (ransomware-style) and sensitive data was reportedly stolen.

Why it is dangerous: Patient records and hospital operations may be unavailable or leaked, putting patients' privacy and care at risk, and hospital staff are disrupted.

Are you affected?

You are affected if you are a patient, staff member, or partner whose data is held by Kamalnayan Bajaj Hospital.

Kamalnayan Bajaj Hospital systems: nine servers (details of software and versions unknown).

What to do

  1. Keep backups of current data isolated from the network, and do not pay or respond to ransom demands without expert and legal advice.
  2. Report the incident to your local cyber crime authority and the data protection regulator if your data may be involved.
  3. Watch for phishing or fraud messages that use stolen patient or staff details.
  4. Change passwords and enable multi-factor authentication on accounts that could be affected.
