Health giant Medibank has confirmed its customers’ data may have been compromised in a cyber security breach last week.
While initially playing down the impact of the attack, on Wednesday the company confirmed it had been contacted by criminals claiming to have stolen 200GB of data.
“The criminal has provided a sample of records for 100 policies which we believe has come from our ahm and international student systems,” the company said in a statement.
Data accessed by the criminals includes first and last names, phone numbers, addresses, dates of birth, Medicare numbers, policy numbers and cases claims data.
The claims data includes sensitive medical information relating to conditions and procedures as well the location of where a customer received medical services.
“The criminal claims to have stolen other information, including data related to credit card security, which has not yet been verified by our investigations,” the company said.
Medibank said it was in the process of notifying individual customers if their information had been affected and informing them of what steps to take.
The company added that the number of affected customers is expected to grow as the incident continues to unfold.
“I unreservedly apologise for this crime which has been perpetrated against our customers, our people, and the broader community,” Medibank chief executive David Koczkar said.
“I know that many will be disappointed with Medibank and I acknowledge that disappointment.”
The breach is being investigated by the Australian Federal Police.
More to come.
