A hacking group leaked a vast amount of internal Disney data, including information on unreleased projects, raw images, computer codes, and some logins. Known as Nullbulge, the group told CNN it published around 1.2 terabytes of information from Disney's Slack. In an email to CNN, Nullbulge explained they did so through a "man with Slack access who had cookies" and mentioned they are based in Russia.

Disney has acknowledged the intrusion and said it is looking into the matter. The hacking group's email explained that the user tried to kick them out of the system at first but was unable to block access, allowing Nullbulge to break back in.

Nullbulge explained that theirs had been an action motivated by demands for better artist rights and good compensation in relation to artificial intelligence. They criticized Disney for poor treatment of artist contracts, AI policies, and consumer relations.

The group had been teasing the massive leak on social media for weeks. In June, they posted what seemed to be visitor, booking, and revenue data from Disneyland Paris. Artificial intelligence has already been an immense sticking point in recent Screen Actors Guild and Writers Guild of America strikes, with writers and actors concerned that AI will replace their work.

The hackers claim that they chose leakage over any sort of negotiation with Disney simply because such a conversation would be futile. They pointed out past precedents, like the 2014 Sony Pictures hack that caused an international crisis and brought sensitive company information to light.
