Disney's CFO Hugh Johnston said most of the media and entertainment company's businesses would stop using the service later this year.

Many teams have already started transitioning to streamlined enterprise-wide collaboration tools.

The Wall Street Journal reported in July that hacking group NullBulge had published data from thousands of Slack channels at the entertainment giant, including computer code and details about unreleased projects.

WSJ reported earlier this month that the data spans more than 44 million messages from Disney's Slack workplace communications tool.

NullBulge compromises software supply chains by exploiting code on GitHub and Hugging Face, collaborative coding platforms, and tricks users into downloading malicious files, as per SentinelOne's threat intelligence and malware analysis team.
