While the countdown continues towards Game of Thrones Season 7 Episode 4, HBO has suffered from a widespread cyber-attack where hackers leaked what is alleged to be a script or a treatment for next week's episode online. While the actual episode itself hasn't leaked yet, the hackers did leak this coming week's episodes of Ballers and Room 104, with the hackers also threatening to release even more data. Here's what HBO had to say about the attack in a statement.

"HBO recently experienced a cyber incident, which resulted in the compromise of proprietary information. 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."

Entertainment Weekly reports that over 1.5 terabytes of data was stolen from HBO, although there was no clear motive given for the attack, what will be released next or when the next leak may happen. This comes just a few months after the Netflix hack, where a group released new episodes of Orange is the New Black early, while demanding a ransom be paid. Following the leak HBO chairman and CEO Richard Plepler sent out a company-wide email this morning, which you can read below.

"As most of you have probably heard by now, there has been a cyber incident directed at the company which has resulted in some stolen proprietary information, including some of our programming. Any intrusion of this nature is obviously disruptive, unsettling, and disturbing for all of us. I can assure you that senior leadership and our extraordinary technology team, along with outside experts, are working round the clock to protect our collective interests. The efforts across multiple departments have been nothing short of herculean. It is a textbook example of quintessential HBO teamwork. The problem before us is unfortunately all too familiar in the world we now find ourselves a part of. As has been the case with any challenge we have ever faced, I have absolutely no doubt that we will navigate our way through this successfully."

HBO and the hit series Game of Thrones is no stranger to leaks. The network stopped sending out Game of Thrones screeners to members of the press, after the first four episodes of Season 5 leaked before their debut. Despite these efforts, Game of Thrones has "won" the title of the most pirated show for the last five years. It remains to be seen if these hackers will release any of the upcoming Game of Thrones episodes or not, or if they will ultimately reveal why they're attacking the company.
