Disney to stop using Salesforce-owned Slack after hack exposed company data, WSJ reports

(Reuters) -Walt Disney plans to transition away from its use of Slack as a companywide workplace collaboration system, after a hacking entity leaked online more than a terabyte of company data, the Wall Street Journal reported on Thursday, citing a memo.

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, according to the report.

Disney and Salesforce's Slack did not immediately respond to Reuters requests for comment.

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

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

The company had said in August it was investigating an unauthorized release of over a terabyte of data from one of its communication systems.

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.
