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 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.
