The latest quarterly data breach report from the Office of the Australian Information Commissioner (OAIC) has revealed over 10 million individuals had their information compromised in one single incident. The current population of Australia is around 25.4 million.
The breach was disclosed to the OAIC under the Notifiable Data Breaches (NDB) scheme between January 1, 2019, and March 31, 2019 and reported in its Quarterly Statistics Report [PDF].
While the report did not detail the origin of the breach that affected over 10 million individuals, it did show that the most number of affected individuals from a single finance-related breach was less than 500,000 and the health sector’s three heaviest impacting breaches affected less than 5,000 individuals each.
In total, the OAIC received 215 data breach notifications, down from the 262 reported in the October to December 2018 period. 62 breaches were reported in January, 67 in February, and 86 in March.
