After cyberattack in Australia, hackers leak medical records

Hackers have announced that they will continue to release personal information.

Hackers began disclosing stolen sensitive medical records to a major Australian health insurance company on Wednesday that had previously refused to pay a ransom demand, the insurer said, expecting more leaks.

Mediabank, one of Australia's leading private health insurers, has told its investors and customers that a sample of data from its approximately 9.7 million customers had been posted on a hidden web forum.

Names, passport numbers, dates of birth, addresses and medical information were among the personal data posted anonymously on Wednesday morning.

The files appear to be a sample of the data whose we previously determined that they were accessed by the criminal, the company said in a statement to the Australian Securities Exchange.

We expect the criminal to continue posting files to the hidden web, she continued.

The leaked data was posted on a forum that cannot be found using common browsers.

We will continue to post partial data, hackers warned on the forum.

The company revealed on Monday that a cyberattack had allowed access to the names, birthdates, addresses, phone numbers and emails of its customer base.

An anonymous netizen claimed on a hacking blog on Tuesday that the data [would] be released within 24 hours, a message widely picked up by local media.

Medibank had then called on its customers to be vigilant in the face of this worrying threat, brandished a day after the insurer had ruled out paying a ransom.

Cybercrime experts believed that paying a ransom had only a limited chance of securing the return of stolen data, Medibank Chief Executive David Koczkar explained at the time, and that this could encourage direct extortion from its customers, he added.

The Medibank hack comes after a September attack on the country's second-largest cellphone operator, Optus, which leaked the personal details of some 9 million Australians, almost a third of the population. lation.
