Yakult Australia 'aware' of dark web data leak following cyber incident

The manufacturer of probiotic milk drink, Yakult, has become the latest company to fall victim to a significant cyberattack.

Both the company's Australian and New Zealand IT systems were subject to a "cyber incident" Yakult said in a statement published on its website.

Approximately 95GB of data was stolen during the hack in mid-December, which was later leaked on the dark web. The exact nature of the data or how much of it was posted online is unclear.

Director of Yakult Australia, David Whatley, told 9news.com.au, he became aware on Christmas Day "that the threat actor had published on their dark web forum at least some of the data they claim to have taken".

Whatley did not provide specific details on the data stolen but said the incident is currently under investigation.

"We are working with our cybersecurity experts to investigate the extent of the incident and what data has been accessed," he said.

"Our investigations are ongoing, and we cannot yet confirm the extent of the incident.

"We have reported the incident to law enforcement and will work with the relevant authorities in response to this incident.

"We are unable to provide any further comment at this time."

Yakult Australia has notified the Australian Cyber Security Centre, the New Zealand National Cyber Security Centre, the Office of the Australian Information Commissioner, and the Office of the Privacy Commissioner New Zealand following the incident.

The company confirmed its offices in Australia and New Zealand will remain open and continue to operate.

Yakult Australia is based in Dandenong in Victoria.
