HBO is the latest entertainment company to be hacked.
Entertainment Weekly reports that hackers claim they took 1.5 terabytes of data from the pay-cable channel and that they put upcoming episodes of "Ballers" and "Room 104" online. But the big find would be a script from the fourth episode of "Game of Thrones," airing next week.
"HBO recently experienced a cyber incident, which resulted in the compromise of proprietary information," the network confirmed in a statement to EW. "We immediately began investigating the incident and are working with law enforcement and outside cybersecurity firms. Data protection is a top priority at HBO, and we take seriously our responsibility to protect the data we hold."
Many reporters received an anonymous email on Sunday announcing the hack, according to EW.
"Hi to all mankind," the email reads. "The greatest leak of cyber space era is happening. What's its name? Oh I forget to tell. Its HBO and Game of Thrones……!!!!!! You are lucky to be the first pioneers to witness and download the leak. Enjoy it & spread the words. Whoever spreads well, we will have an interview with him. HBO is falling."
It's unclear whether the hacker has possession of any completed episodes of "Game of Thrones." HBO would not say what might have been stolen.
Though the biggest hack within the entertainment industry is still that of Sony in 2014, there have been smaller ones recently. Netflix was hacked in April, and episodes from season five of "Orange is the New Black" were put online ahead of its summer launch. Then in May, a hacker claimed to have stolen Disney's "Pirates of the Caribbean: Dead Men Tell No Tales," but studio head Bob Iger later said it was a hoax.
