All Medibank customers – including those with ahm and international – have had their personal data exposed to hackers, the insurance giant has revealed.
Medibank revealed the update this morning as hackers continue to demand ransom for the data stolen last Tuesday.
“Our investigation has now established that the criminal had access to all ahm customers’ personal data and significant amounts of health claims data; all international student customers’ personal data and significant amounts of health claims data; all Medibank customers’ personal data and significant amounts of health claims data,” Medibank said in a statement.
“As a result, we expect that the number of affected customers could grow substantially.”
Medibank said its IT systems had not been encrypted by ransomware yet, and customers could continue to access health services.

“Australians who are struggling with mental health conditions, drug and alcohol addiction, with diseases that carry some shame or embarrassment, they are entitled to keep that information private and confidential,” she said.
“For a cybercriminal to hang this over the heads of Australians is a dog act. It is scum of the earth, lowest of the low territory.”
The AFP is continuing to investigate the incident.
