Disney plans to transition away from its use of Slack as a companywide workplace collaboration system, a move that comes after a hacking entity stole and leaked online more than a terabyte of company data.

Disney's CFO Hugh Johnston said most of the media and entertainment company's businesses would stop using the service later this year, the report said. Many teams have already started tranisitioning to streamlined enterprise-wide collaboration tools,

A 1.1 TB file, allegedly collated from Disney's internal Slack archive, was published by a group calling itself "Nullbulge" in July, apparently in protest over artist rights. According to Wired, the group had insider access and exposed data including messages, information about internal projects, and employees' personal details.
