U.S. cable channel HBO said on Monday that hackers had stolen upcoming programming, and Entertainment Weekly reported that the theft included a script for an unaired episode of the hit fantasy show ¡°Game of Thrones.¡±

HBO, a unit of Time-Warner Inc, declined comment on the specific programming stolen in 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,¡± HBO Chairman Richard Plepler wrote in a message to employees, which the company shared with reporters.

The company declined comment on reports that unbroadcast episodes and scripts were among the data hacked, citing an ¡°ongoing investigation¡± by unspecified law enforcement officials.

Entertainment Weekly reported that hackers stole 1.5 terabytes of data and had already posted online unbroadcast episodes of ¡°Ballers¡± and ¡°Room 104,¡± along with ¡°a script or treatment¡± for next week¡¯s episode of ¡°Game of Thrones.¡±

Reuters also received an e-mail on Sunday from a person claiming to have stolen HBO data, including ¡°Game of Thrones.¡±

The show is now in its seventh season and due to wrap up next year.
