After promising to release more data stolen from HBO, the hackers behind the data breach at the company made good on its threats Monday night. The group released a new trove of data that includes the personal contact information of Game of Thrones actors.

The latest release from the hacking group, which refers to itself as little.finger66, included technical data about HBO’s internal network, administrator passwords, draft scripts from a number of Game of Thrones episodes — including the episode set to air Sunday — and communications from HBO’s vice president for film programming, Leslie Cohen.

One of the documents contained in the leak including personal phone numbers, home addresses and email addresses for the season seven cast of Game of Thrones including actors Peter Dinklage, Lena Headey, and Emilia Clarke.

Despite the most recent release of data including emails, HBO has held that its email server was not breached. In a statement to Wired, HBO spokeperson Jeff Cusson said “the review to date has not given us a reason to believe that our email system as a whole has been compromised.”

Accompanying the latest leak was a letter from the hackers. In it, a spokesperson who identified himself as “Mr. Smith” provided some details about the group’s efforts to hack HBO and issued a demand for payment from HBO in order to stop further leaks of data.

In the letter, Mr. Smith claimed it took the hacking collective about six months to breach HBO’s network, calling the company “one of our difficult targets to deal with.” But once the group penetrated the content maker’s networks, they made off with a significant score of valuable information.

“By penetrating your internal network and other related platforms, we obtained your highly confidential documents,” Mr. Smith said. According to the note, the group stole and is prepared to leak contracts and “mutual agreements,” human resources documents, business and marketing strategies, IT infrastructure information, and other documents.

The group claims to have “very detail info” on how HBO produces its films and TV series, including documents that show detailed budgets and “confidential research.” The hackers also claim to have proof of HBO evading taxes.

The hackers admitted in the letter that HBO has carefully protected its Game of Thrones content, but warned they had collected enough to produce a “tiny mini-series” of season seven content that will “shock the entire world” and “put an end to fate of this season” as well as “corrupts your ideas and efforts” for season eight.

While the group claimed that its motivations aren’t political or financial and “money isn’t our main purpose,” the hackers did demand a sizable ransom from HBO in order to put an end to the ongoing leaks of internal information.

While the amount was redacted from the letter, the group asked for a “six-month salary” paid in bitcoin. The hackers claim to make about $12 to 15 million per year while spending an upwards of $500,000 on zero day exploits to carry out their attacks.

Still, the group called themselves “white hat hackers” and dismissed any comparison to theDarkOverlord who carried out the hack that resulted in episodes of Orange is the New Black being stolen and published online. “You will see in future steps in our operation that we fulfill any promises made and any given word,” the group wrote.
