Medibank cyber attack: Private health insurance detects cyberattack, takes several services offline as a precaution | 7NEWS
One of Australia’s largest private health insurers has revealed it was the target of a possible cyberattack.
Medibank Group on Thursday said it had detected “unusual activity” on its network a day earlier.
Specialised cybersecurity firms were called in as a result and preliminary investigations found there was no indication that sensitive data, including customers’ identifying information, had been compromised.

But as a precaution, Medibank Group said it had taken several services offline.
“As part of our response to this incident, Medibank will be isolating and removing access to some customer-facing systems to reduce the likelihood of damage to systems or data loss,” Medibank said in a statement.
“As a result our ahm and international student policy management systems have been taken offline. We expect these systems to be offline for most of the day.”
Medibank’s CEO David Koczkar said the news would be concerning in the “current environment”.
Last month, almost 10 million Optus customers’ had their information compromised in a cyberattack.
More than 10,000 of those customers’ data was leaked online before the so-called hacker withdrew a threat to release more.
“Our highest priority is resolving this matter as transparently and quickly as possible,” Koczkar said.
“We will continue to take decisive action to protect Medibank Group customers and our people.
“We recognise the significant responsibility we have to the people who rely on us to look after their health and wellbeing and whose data we hold.
“We are working around the clock to understand the full nature of the incident, and any additional impact this incident may have on our customers, our people and our broader ecosystem.”
Medibank said its investigation was ongoing and customers would be provided with regular updates.
According to its website, Medibank has 3.7 million members across Australia.
