Sanctions imposed and security upgrades pursued after Medibank data breach
Australia's Medibank suffered a personal data breach in a 2022 cyber-attack. The regulator alleged that stolen credentials and a lack of multi-factor authentication enabled the intrusion and that the response was also delayed. Australia and other countries imposed sanctions on a Russian hacker involved, and Medibank decided to invest A$126 million in security improvements after the incident.
