Treasurer Stephen Mullighan told parliament on Wednesday a “forensic review” by PricewaterhouseCoopers (PwC) uncovered the additional people that had had their personal data stolen, in addition to the 80,000 employees announced by the former government last year.

The data, which included tax file numbers and bank account details, was stolen when the state government’s payroll provider, Frontier Software, was hacked in November.

“The attack was perpetrated by an overseas criminal organisation on Frontier’s network and this data, amongst others, was accessed,” Mr Mullighan said.

“After accessing this information, the perpetrators deployed ransomware to Frontier’s systems and posted some of the files to the dark web.”
