More than a terabyte of data believed to have been obtained from Disney's internal messaging channels has been leaked online by a self-proclaimed "hacktivist group," including login credentials, code, images and information about unreleased projects.

An anonymous group calling itself Nullbulge has claimed responsibility for the leak, claiming it gained access to the company's Slack messaging data using a Disney employee's compromised computer. “We downloaded and packaged everything we could,” Group X said, claiming to have obtained “1.1 TiB of files and chats” from nearly 10,000 corporate Disney Slack channels. Disney has since confirmed to The Wall Street Journal that it is "investigating the matter."

Nullbulge said it was in possession of the stolen data on July 12, hours before Disney's Slack archive was leaked. WSJ reports that the file contains the internal dialogue on software development, recruitment, maintenance of the site and internal dialogue on employee programs dating back to "at least 2019." According to Eurogamer, the detailed information about the upcoming game collaboration and the unprecedented video game followers have also begun to emerge through leakage files.

Nullbulge said its goal is to protect the artist's rights and wages and tell WSJ that it aims at Disney, "how to handle the artist contract, the method of AI and the obvious ignores consumers."

The threat of the generated AI for creative professionals is one of the most significant awareness of stimulating the workers of the Union of Disney Animators and the 2023 case-night strike. Disney has also been criticized for using generative artificial intelligence to create end credits for Disney+ series, and has reportedly formed a task force to study how to apply artificial intelligence to its entertainment portfolio.
