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. This follows a summer hack that exposed over a terabyte of sensitive company data, including financial records, computer codes, and details of unreleased projects. Salesforce CEO Marc Benioff emphasized the importance of strong security measures and noted that Disney still uses Salesforce for other functions.
