SingHealth’s database containing patient personal particulars and outpatient dispensed medicines was recently the target of a major cyberattack.

SingHealth is contacting all patients who visited its outpatient clinics and polyclinics from 1 May 2015 to 4 July 2018. The patients will be informed if their data had been illegally exfiltrated.

Meanwhile, patients can check if their data had been compromised SingHealth's website, or the Health Buddy mobile app at sg.sg/healthbuddy. Patients can also e-mail SingHealth at check@singhealth.com.sg

Here are five precautionary measures you can take to protect yourself online.
