HBO hit with major cyber attack: 'Game of Thrones' data leaked online

HBO is the latest media company to fall victim to a massive cyber attack, the network confirmed in a statement on Monday.

Hackers have allegedly obtained 1.5 terabytes of data from the company, which include upcoming episodes of "Ballers" and "Room 104" as well as a script from next week's episode of "Game of Thrones."

"HBO recently experienced a cyber incident, which resulted in the compromise of proprietary information," the network confirmed in a statement on Monday morning. "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."

The network's chairman and CEO Richard Plepler sent an email to employees alerting them of the hack:

"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."

Reporters were notified of the hack in an eerie email on Sunday night:

"Hi to all mankind. 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."

Earlier this year, Netflix suffered a breach of its own when a hacker released episodes from season 5 of "Orange is the New Black" ahead of its summer premiere. Sony suffered the biggest hack to date back in 2014 when approximately 100 terabytes of data was uploaded online.
