A hack on an Australian health insurer appears to be far larger than initially suspected, with the company saying it will refuse to pay a ransom for the theft of data.

The attack on Medibank Private Ltd. exposed the data of around 9.7 million current and former customers and some of their authorized representatives, the Melbourne-based company said in a statement Monday. Accessed data included the victim’s name, date of birth, address, phone number and email address. Initially, Medibank said the attack had exposed data on its almost 4 million customers.
