Hacker demands $10m to stop leaking Australians’ medical recordsCyber-extortionist posts medical information purporting to show details of abortions and treatments for addiction, HIV.Local media have linked the dark web forum used to post the hacked data to the crime group REvil, which Russian authorities said they shut down earlier this year at the request of the United States.Medibank CEO David Koczkar on Thursday condemned the hacker’s actions as “disgraceful” while reiterating an apology to customers.“The weaponisation of people’s private information in an effort to extort payment is malicious, and it is an attack on the most vulnerable members of our community.”Medibank has refused to pay the ransom, citing advice from cybercrime experts that doing so would not ensure the return of customers’ information and could put “more people in harm’s way by making Australia a bigger target”.The Australian Federal Police, which is investigating the cyberattack, has warned that downloading or even just accessing the data could be a criminal offence."
