Frequently Asked Questions


SingHealth’s IT system containing patient personal particulars and information on outpatient dispensed medicines has been the target of a major cyberattack. Forensic investigations have confirmed that this was a deliberate, targeted and well-planned cyberattack, and not the work of casual hackers or criminal gangs.

We have lodged a Police report on the incident, and the matter is currently under Police investigation.

We apologise for the anxiety caused. Please rest assured that additional cybersecurity measures have been implemented to safeguard patients' data.

SingHealth was alerted by our IT partner IHIS who runs the IT systems for the public healthcare institutions. They detected that there was unusual activities on one of our IT databases. They took immediate action to halt the activities and investigated the incident to ascertain the nature of these activities. They also put in place additional precautionary cybersecurity measures immediately. There was no further illegal data access thereafter.
