In what is Singapore's worst cyber attack to date, hackers have stolen personal data of the equivalent of a quarter of the population. That's according to officials.

The Singaporean Prime Minister tweeted to confirm that even his own own personal records had been stolen and that the authorities would tighten up and defenses and processes.
Government officials did not say who might have been behind the attack, but a joint statement by the health and communications ministries suggested a high degree of sophistication. The cyber attack comes as the state has made cybersecurity a top priority for the ASEAN bloc and for itself.
