First Optus, now Medibank; in less than two months we’ve experienced two of the largest personal data breaches in Australia’s history. In both cases the hackers attempted, and failed, to extort a ransom in exchange for not releasing personal data.
So far the Optus hackers have released only a small sample of data, and claim to have deleted the rest. On the other hand, the Medibank hackers have released the records of more than one million people – and have threatened to release more data on Friday.
