An unaired 'Game of Thrones' episode has been reportedly leaked by a hacker

The INSIDER Summary:

• HBO was recently hacked in a cyber-security attack.
• Several episodes of TV shows were reportedly stolen.
• Now a full episode of "Game of Thrones" appears to have been leaked on Friday.
• The episode, "Spoils of War," is scheduled to premiere on Sunday.
• There is some indication that the episode leak wasn't related to the earlier HBO hack.

Early this week, HBO released a statement concerning a recent cyber-security hack. While initial reports indicated that full episodes of "Ballers" and "Insecure" had been stolen, it appears now as though a new "Game of Thrones" episode has leaked as well.

Tatiana Siegel of The Hollywood Reporter tweeted early Friday morning, saying "sources inside HBO say [the leak was] NOT related to hack." Instead, it may have been "lost by Indian distributor."

On Friday morning, a Reddit community called /r/FreeFolk reported that the full fourth episode of "Game of Thrones" season seven, "Spoils of War," was now available to download. "Free Folk" is a subreddit created by "Game of Thrones" fans who knew about leaks and spoilers as a place for discussion of said leaks.

Based on screenshots taken, the episode circulating is HBO's internal version of "Spoils of War." 

The "Free Folk" subreddit was also the hub of discussion in 2016 when descriptions of season six episodes were being leaked ahead of the series' air date. The apparent leak of a full season seven episode marks the third time in "Game of Thrones" history that full sections of upcoming seasons have been stolen and placed online. 

In 2015, four episodes were leaked ahead of the fifth season premiere. In 2016, as noted earlier, verbal descriptions of upcoming episodes were being shared ahead of their airing, and then a single episode ("The Door") was leaked online one day before its premiere on HBO.

The new 2017 hack, done by an anonymous person using the moniker "Little.Finger66," also included the theft of thousands of internal documents. One document already circulating was an early draft of the outline for episode four, "Spoils of War." Whether or not more content from the seventh season of "Game of Thrones" was stolen remains to be seen. HBO did not immediately respond to a request for comment.

"Spoils of War" is officially premiering Sunday at 9 p.m. on HBO.
