A forensic investigation is ongoing and HBO is still reviewing what data has been leaked.
Along with the emails were files marked "Confidential" and "Script GOT7" and a video of demands addressed to HBO CEO Richard Plepler.
Hackers behind the hack of HBO release what appears to be emails from an HBO executive's inbox.
The hackers released 3.4GB of files, which, in addition to the aforementioned draft scripts, include a month's worth of emails from HBO film programming VP Leslie Cohen, as well as internal network and administrator passwords.
The hackers who stole 1.5 terabytes of data from HBO have leaked a huge load of information on the network. The cable giant is still of the view that there's not enough evidence to suggest that its email system as a whole has been compromised.
Hackers of United States television network HBO have released personal phone numbers of Game of Thrones actors, emails and scripts in the latest dump of data stolen from the company, and are demanding a multimillion-dollar ransom to prevent the release of whole TV shows and further emails. Beyond those leaked scripts, the spill contains countless HBO internal documents, including emails, financial balance sheets, employment agreements, and marketing-strategy PDFs. To stop the leaks, the purported hackers demanded "our 6 month salary in bitcoin", which they implied is at least $6 million.
HBO, which previously acknowledged the theft of "proprietary information", said it is continuing to investigate and is working with police and cybersecurity experts.
HBO has provided few details about the hack.
An HBO spokesperson, in a statement to THR, responds: "HBO believed that further leaks might emerge from this cyber incident when we confirmed it last week". The report said it is not clear whether the link it received was also sent to other media outlets.
