Health insurance company Medibank announced that the hacker responsible for the data breach that had affected the company in October 2022 released the data on the dark web. The company said that the data released contained personal information including names, home and email addresses, dates of birth, phone numbers, Medicare numbers for customers, in some cases passport numbers of international students, and some health claims data. While it is expected that the hacker will continue to release data on the dark web, the company is working with the Australian Cyber Security Centre and the Australian Federal Police to investigate the attack. Customers will be informed further about the data believed to be stolen and the steps they should take. For now, the company said that customers should be alert for phishing scams, verify communications, change passwords regularly, and refrain from opening text from suspicious numbers.
