Both the company's Australian and New Zealand IT systems have been affected.
Cybercrime actor DragonForce which claimed responsibility for the attack has also leaked 95 GB of data that it states, belongs to the company.
Invented in 1935 in Japan and now sold around the world, Yakult is a fermented and sweetened milk beverage with live bacteria, consumed to support digestion and the immune system.
In a statement to BleepingComputer, Yakult Australia confirmed it was investigating a cyber incident that occurred in mid-December.
The company is currently unable to confirm how exactly the incident occurred.
While the company's IT systems in Australia as well as New Zealand were hit, the offices in both regions remain open and operational.
A cybercrime actor that calls itself 'DragonForce' has taken responsibility for the incident and listed Yakult Australia to its onion leak site on December 20th, while publicly threatening to leak 95.19 GB of data, which the group has now done.
BleepingComputer analyzed a small portion of the leaked dump that appeared to contain several business documents, spreadsheets, credit applications made by Yakult Australia, employee records, and copies of identity documents such as passports.
Not much information is currently known about 'DragonForce', which has listed 20 victims on its leak site thus far.
The threat actor does not yet seem related to DragonForce Malaysia, a hacktivist group that has earlier targeted government agencies in the Middle East.
