Hacker demands $10m to stop leaking Australians’ medical records

A cyber-extortionist has demanded almost $10 million to stop leaking the medical records of Australians caught up in one of the country’s worst cyberattacks.

In a message posted on the dark web early on Thursday morning, the hacker said it was demanding $1 from Medibank, Australia’s largest private health insurer, for each of the 9.7 million customers affected in an enormous data breach last month.
