A hacker group released data on Monday that it claims to be have obtained from the HBO breach, including a synopsis of an upcoming “Game of Thrones” episode, along with contents from a network executive’s email inbox.

The hackers refer to this latest information dump as the “second wave” following last week’s release, which included episodes of “Ballers” and “Insecure” and a “Game of Thrones” script.

A file in the new release is a video containing what appear to be descriptions of scenes from the fifth episode of “GoT” Season 7, set to air on Sunday.

One file is labeled “Script GOT7 E- 05,” while another contains screen shots of information related to “Game of Thrones,” including details on marketing and castings.

Also included is the group’s purported first ransom notice to HBO, in which the hackers claim that it took them six months to breach the network’s system.

The letter demands money to prevent the release of data. The message also claims that HBO is the 17th target of the hackers, and that all but three of those paid the ransom.

“Our demand is clear and Non-Negotiable: we want [amount redacted] dollars to stop leaking your data,” the hackers allegedly told HBO.

HBO said in a statement that the network does not believe that hackers have full access to the network’s email system.

“HBO believed that further leaks might emerge from this cyber incident when we confirmed it last week,” the statement read. “As we said, the forensic review is ongoing. While it has been reported that a number of emails have been made public, the review to date has not given us a reason to believe that our e-mail system as a whole has been compromised.”

“We continue to work around the clock with outside cybersecurity firms and law enforcement to resolve the incident,” the network message continued. “Meanwhile, our dedicated employees continue to focus on delivering the high quality of entertainment and service for which we are known.”

Last weekend’s “Game of Thrones” episode was leaked to the internet several days prior to the episode airing, although this was determined to be unrelated to the hack.
