'Game of Thrones' script leaked online after hackers invade HBO

HBO reported Monday its network was victimized by a cyber attack, with media accounts stating that the hack resulted in the leak of a script of the popular series Game of Thrones including content from other productions.

The Time Warner-owned TV group disclosed that a "cyber incident" resulted in "the compromise of proprietary information," and that the company had taken measures such as contacting law enforcement and outside cyber security firms.

The statement did not indicate what was compromised, but several media reports revealed that hackers obtained the script of a new episode of the award-winning fantasy series along with unaired episodes of two other programs, Ballers and Room 104.

"Any intrusion of this nature is obviously disruptive, unsettling and disturbing for all of us," HBO chief Richard Plepler said in a memo to staff.

"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."

Furthermore, some media journalists, including one from AFP, received emails from an unidentified address boasting of the breach and proposing to showcase unaired content from Game of Thrones.
