I'll leave you with some of your thoughts about today's developments:

When Medibank call you this morning to say you’re in the 2% of the entire data leak with details being viewed and accessed…It shook me to my core. - Marjorie

Good work! I am sure that our “white hats” are now working on strategies to disable the servers if these reprehensible cyber criminals. - Peter E

Aren’t we technically at war with Russia so why would Russian LE help the AFP? - Rick

Well what’s the AFP and the government doing about it? People need to see action not just words - Peter

Speaking earlier, Commissioner Reece Kershaw said the government does not condone ransoms, because any payments "small or large fuels a cybercrime business model".

The ABC's defence correspondent Andrew Greene says Medibank has made a clear declaration it will not pay.

Andrew: Medibank has been working closely with the AFP from the outset, as well as with cyber security authorities – the Australian Signals Directorate and the Australian Cyber Security Centre. 

Medibank has made a clear declaration it will not pay a ransom, unlike some other high-profile victims of cybercrimes.

The ABC's defence correspondent Andrew Greene says none of this is really a shock.

Andrew: No, before today it was widely believed that Russian hackers were responsible for this hack, and although the AFP won’t publicly identify the group responsible, sources have told the ABC it is REvil – which is based in Russia, but has affiliates and associates in other countries

As we heard a short time ago, the AFP will hold talks with Russian law enforcement about those they believe to be responsible.

He says the AFP is responsible for the Australian INTERPOL National Central Bureau, which has direct contact with National Central Bureau Moscow.

"INTERPOL National Central Bureaus cooperate on cross-border investigations, operations and arrests.

"To take investigations beyond national borders, they can seek cooperation from any other National Central Bureau.

"It is important to note that Russia benefits from the intelligence-sharing and data shared through INTERPOL, and with that comes responsibilities and accountability."

Thanks for writing in Dennis. Commissioner Reece Kershaw spoke about this one a little earlier, saying Australian government policy does not condone paying ransoms to cyber criminals.

The ABC's defence correspondent Andrew Greene says it's generally unusual for Australia to do attributions for cyberattacks at all.

Andrew: But given the severity of this attack and in the context of the current geo-political environment following Russia’s invasion of Ukraine a decision has been made by the government to call Russian criminals out as the culprits for this attack.

Thanks for writing in — it's a fair point.

We put this one to the ABC's defence correspondent Andrew Greene.

Andrew: Australia is unlikely to receive any cooperation from Russian authorities. Although REvil is not considered part of the Russian state, it operates with the protection of President Vladimir Putin. 

Before Russia’s invasion of Ukraine western nations were already furious at Moscow for harbouring cybercriminals. Australia’s strong support of Ukraine makes it certain that Russia will not want to cooperate.

The ABC's defence correspondent Andrew Greene has dropped in to answer a few questions about that update from the AFP and some of the main takeaways.

So what do we know about those responsible?

Andrew: Authorities suspect the perpetrators of the Medibank hack are members of the REvil group – a Russian based cyber-criminal gang. 

Russia is a member of Interpol – and AFP Commissioner Reece Kershaw says Australia will seek to discuss the crime with Russian authorities. 

If you missed the update from Commissioner Reece Kershaw a short time ago, the AFP has now released a full statement:

This cyber attack is an unacceptable attack on Australia and it deserves a response that matches the malicious and far-reaching consequences that this crime is causing.

The AFP is undertaking covert measures and working around the clock with our domestic agencies and our international networks, including INTERPOL.

Commissioner Kershaw says cyber crime is the "break and enter of the 21st century", adding that "personal information is being used as currency".

"Finally, I want to reiterate, the Australian government policy does not condone paying... ransoms to cyber criminals. 

"Any ransom payment, small or large, fuels a cybercrime business model, putting other Australians at risk."

That brings the press conference to a close.

Commissioner Kershaw is asking the media and those on social media to "do the right thing" and not aid "these criminals" by posting or publishing sensitive information.

"This is a time for all Australians, the community, business and law enforcement to stand together," he says.
