Ransomware hackers attack health insurer

Australian health insurance company Medibank has faced a ransomware attack which is threatening to leak 9.7 million customers’ information. The company admitted that more than 500,000 health claims had been accessed and threatened to be sold on the dark web. Medibank has since refused to pay the ransom to known Russian ransomware group REvil. The group’s chief executive David Koczar said that paying the ransom would make Australia a “bigger target”.
