Disney to Stop Using Slack After a Hack Leaks 1TB+ of Internal Data

From PC Mag: Disney plans to stop using Slack after a hack leaked 1TB+ of company data earlier this year, the WSJ reports, citing an internal memo from Disney CFO Hugh Johnston.

According to the memo, first reported by Oliver Darcy's Status newsletter, most businesses under Disney will move away from Slack by the end of this year, while "some complex" units will complete the transition by the second quarter of 2025. It's unclear which app Disney will use going forward.

"I would like to share that senior leadership has made the decision to transition away from Slack across the company," said Johnston in the memo. "Our technology teams are now managing the transition off Slack by the end of Q1 FY25 for most businesses."

Slack is a popular business messaging app that many companies use for internal communication. Earlier this year, an anonymous hacking group called "Nullbulge" hacked into thousands of Disney's Slack channels, reportedly via a software engineer's computer, and posted screenshots of the data on X in July.

The group also claimed to have obtained descriptions and plans of some upcoming Disney projects, along with booking and revenue data from Disneyland Paris.
