HBO didn't have much to say about the hack, only confirming that the incident is under investigation.
When will the eighth and final season of "Game of Thrones" air?
"This entire situation of a big corporate entity going back and forth with hackers is something you would see on an HBO show". They claim to be white hat; however, that is in dispute.
According to media reports, the episode, "Death is the enemy", was available for about an hour before it was taken down.
But an official subsidiary of HBO themselves leaking an episode is certainly new.
Game of Thrones's next episode has been pirated and shared online in the latest leak to hit the fantasy TV series.
HBO has been hacked. Season 7 began filming in August 2016 and production ran for about six months - the same time span as previous seasons, even though there are fewer episodes (seven vs. the usual 10).
"Hollywood companies in particular are beefing up their security systems way more than before the Sony hack in 2014", Belloni said.
New teaser pictures for the upcoming episode of Game of Thrones - titled "Beyond the Wall" - have been released.
Meanwhile, the representatives of HBO are yet to release an official statement about the recent cyber attack.
