Walt Disney CEO Bob Iger revealed Monday hackers stole one of the company's upcoming films and are demanding the studio pay a ransom to prevent the film from leaking online, the Hollywood Reporter reported.

Iger, who was speaking at a town hall meeting with ABC employees in New York City, said Disney would not submit to the demands and is currently working with federal investigators at the FBI.

The hackers demanded Disney pay a huge sum of money, provided in bitcoin. The hackers threatened to release parts of the film online in increments — first 5 minutes at a time, then 20-minute chunks — until the full film is published or their monetary demands are met.

Deadline reported the stolen film is Pirates of the Caribbean: Dead Men Tell No Tales, the fifth installment in the franchise fronted by Johnny Depp. The film is slated to open May 26. The franchise has grossed nearly $4 billion for Disney since the first film of the series was released in 2003. It is unclear how a leak may affect box office sales for the film.

The other prominent film set for release from Disney in the near future is Cars 3, which is due to hit theaters June 16.

The ransom comes shortly after a rumor began circulating that a workprint of the upcoming Star Wars: The Last Jedi — another Disney property — was stolen and being held for ransom. It was later learned the rumor was false.

The attack is reminiscent of a recent effort by hacking group TheDarkOverlord to extort a ransom from Netflix after it stole the fifth season of Orange is the New Black. The group leaked the full run of the unfinished season of the popular Netflix exclusive online via torrents. That leak happened at the end of April, ahead of the scheduled release of the show June 9.

The group claimed also to have access to content from FOX, IFC, National Geographic and ABC, believed to be acquired through audio production company Larson Studios, which works with all of the potentially affected studios.

In the press release accompanying the leaked episodes, the group warned studios: “You’re going to lose a lot more money in all of this than what our modest offer was. We're quite ashamed to breathe the same air as you. We figured a pragmatic business such as yourselves would see and understand the benefits of cooperating with a reasonable and merciful entity like ourselves. And to the others: There's still time to save yourselves. Our offer[s] are still on the table — for now."

The recent onslaught of attacks on movie and TV studios harken back to the 2014 hack of Sony Pictures, which led to the release of sensitive communications between studio executives and employees, and resulted in the leak of several unreleased films including the James Franco and Seth Rogen film, The Interview.

The ransom attempt against Disney comes just days after a massive ransomware attack called WannaCry hit thousands of computer systems around the world, including machines at hospitals and major corporations.
