Disney is set to discontinue the use of Slack as its primary workplace collaboration tool by the end of the first quarter of fiscal year 2025, following a major data breach that exposed over a terabyte of sensitive information. CFO Hugh Johnston informed employees in an internal memo that many teams had already begun transitioning to 'streamlined enterprise-wide collaboration tools'. The breach, attributed to the hacking group Nullbulge, resulted in the leak of 44 million messages and various documents, including financial data. Despite the incident, Disney stated it did not expect any material impact on its operations or financial performance. While Slack will be phased out, Disney will continue to utilize other Salesforce products in different areas of its business. Employees have expressed dissatisfaction about the switch, with some reports indicating a move towards Microsoft Teams as the alternative platform.
