The entertainment company reportedly issued a memo to staff that a migration away from Slack’s collaboration application will conclude next year. The move follows a high-profile data breach that led to the publication of 44 million Slack messages and tens of thousands of documents by a hacking group.

The Walt Disney Company will discontinue its use of Slack for internal communication following a major data breach earlier this year. In a memo from CFO Hugh Johnston, employees were informed that most business units will transition to new collaboration tools by the end of the next fiscal quarter.

The company's Slack server was hacked in July, leading to more than a terabyte of company data being leaked to the public.
