The Australian Federal Police (AFP) believes hackers in Russia are responsible for the cyberattack on Medibank.
AFP Commissioner Reece Kershaw said police believe they know who the individuals responsible are, but will not publicly reveal this information while the case is ongoing.
Last month, Medibank confirmed it had been the subject of a cyberattack.
Medibank believes the information of 9.7 million customers and former customers have been compromised in the breach.
On Monday, Medibank said it wouldn’t pay any ransom to the criminal behind the cyberattack, saying there was only a “limited chance” that paying this would stop the data being published.
Customer data has since been posted on the dark web by the hackers.
The hackers posted more customer data today, which is believed to be related to alcohol and mental health claims.
On Thursday, a document named ‘abortion’ was published on the dark web, appearing to list 303 Medibank customers.
In an update this morning, Medibank CEO David Koczkar said they expected the hackers to continue releasing customer data every day.
Prime Minister Anthony Albanese said today he was “disgusted” by the acts of the hackers, and called for them to be held accountable for the crimes.
Earlier this week, Cyber Security Minister Clare O’Neil called those responsible for the cyberattack “scumbags” and “disgraceful human beings”.
