Medibank hackers say they’ve released all of the stolen data as investigations continue

The Russian Medibank hackers have dumped the single biggest amount of private information online.

The group says this is the entire lot of the stolen data.

November 30 is ‘International Cyber Security Day’ and the date chosen by the hackers to release this information.

In a post, the group, known as REvil, said ‘Happy Cyber Security Day’.

The file totals 6.5 gigabytes. Medibank is now working through it all to confirm it is in fact the information that was stolen from the company servers.

At this stage it does seem likely.

But the task has been made more difficult by the fact that the hackers have failed to match some of the information with the names of customers, as they did on previous occasions.

REvil were demanding $15 million in ransom for the stolen data.

At least 9.7 million Australians have been impacted by the breach, which all began back in early November.

There’s been a range of sensitive information released over the past few weeks, including mental health and drug addiction records.

Medibank customers are being told to be on the lookout for scams, particularly via phone and email.
