Thousands of people have had their data exposed due to a cybersecurity breach of Nine newspapers.
Around 16,000 subscribers to the Sydney Morning Herald, The Age and The Financial Review have had their names, postal addresses and email addresses exposed online.
A spokesperson for Nine said that payment details and passwords were not affected.
The spokesperson said they became aware of the hack to a third-party supplier that accessed subscribers' details by a security researcher.
"We have been made aware by a security researcher that certain personal information held by a third party supplier was not protected to the level of Nine's strict internal data protocols after an unauthorised change," a spokesperson said.
The company made it clear that the data was no longer visible and that there was no breach of Nine’s international technology infrastructure.
“Nine treated this matter seriously and worked with the third party to resolve the issue," a spokesperson said.
Nine is working on contacting all affected subscribers but warned that the breach could put thousands of users at risk of cyber attacks.
It's the second major cyber breach to be reported in two days, after 9,000 sensitive court files were downloaded from the NSW Courts online registry last week.
