Over half (56%) of Australian office workers have had their data compromised as part of a breach or hack, including nearly 3 in 10 (28%) more than once, according to a survey of office workers in Australia, the US, UK and Japan.

Four of Australia’s security firms have questioned whether enough is being done to defend businesses and organisations against security attacks by cybercriminals in the wake of a report by the Office of the Australian Information Commissioner (OAIC) revealing malicious or criminal attacks dominated data breaches over a three month period to the end of June.

Malicious or criminal attacks were the largest source of data breaches in Australia in the three months to the end of June this year, accounting for 62% of all data breaches, according to a new report from the Office of the Australian Information Commissioner (OAIC).
