Pressure is mounting on the Tasmanian premier to explain how he is addressing a cyber security hack amid fears the personal data of school children has been released on the dark web.
Data from the state's education department was accessed after third-party file transfer service GoAnywhere MFT was hacked, it was revealed earlier this week.
Science and Technology Minister Madeleine Ogilvie said on Wednesday nothing had been released onto the dark web.
However, Tasmanian Labor said the names, addresses and dates of birth of school children were leaked on the dark web on Friday.

Labor leader Rebecca White said she has written to Premier Jeremy Rockliff requesting an urgent briefing on the government's response.
"Students and their parents are rightly concerned, and it is vital the premier starts to show the leadership that such a serious situation demands," she said.
"Jeremy Rockliff needs to tell Tasmanians what exactly has occurred, what his government is going to do to manage this extremely concerning data breach, what support is available to families who fear they have been affected, and how that support can be accessed."
Ms Ogilvie, who has not yet confirmed school children's data was released, is expected to give an update to media on Friday afternoon.
