SingHealth

The breach compromised personal data of 1.5 million SingHealth patients.

The incident also compromised outpatient medical data of 160,000 patients that visited the healthcare provider's facilities, which included four public hospitals, nine polyclinics, and 42 clinical specialties.

The attackers used a publicly available hacking tool to breach an end-user workstation.

The workstation was running a version of Microsoft Outlook that was not updated with a patch to address the use of the hacking tool.
