Disney's Slack Hack Fallout

Disney is taking action to secure its systems after a hacking group said over the summer that it compromised the Magic Kingdom's internal messaging channels.

The Bob Iger-led company will discontinue its use of Slack, marking a major shift in how employees communicate across the organization, according to an internal email that I obtained.

“I would like to share that senior leadership has made the decision to transition away from Slack across the company,” Hugh Johnston, Disney's chief financial officer, said in the email to staffers on Wednesday. "Our technology teams are now managing the transition off Slack by the end of Q1 FY25 for most businesses.”

Johnston said that some "more complex use cases" will require extra time to transition off Slack, but that the entire migration from from the messaging application should be completed during the second quarter of 2025.

The move comes after hacking group Nullbulge said over the summer that it had successfully breached Disney's Slack channel. The Wall Street Journal reported in July that it saw leaked files from the company’s Slack. Those leaked documents showed Disney employees discussing a wide-range of topics, many of which were confidential.

At the time, Disney said it was "investigating this matter." A spokesperson for Disney did not respond to requests for comment on Wednesday night. A spokesperson for Slack also did not immediately respond to a request for comment.

It’s unclear how Disney employees will communicate internally after the company ceases using Slack. Johnston didn’t elaborate in his memo, simply saying that teams are “planning and overseeing key workstreams to support this transition, with a focus on reinforcing current TWDC policies for work-related collaboration.”
