'Game of Thrones': Jon Snow and Daenerys Targaryen meet

Fox411: 'Game of Thrones' fans finally got a moment they were waiting for, The King in the North and Mother of Dragons came face to face, but things are getting dark for the Daenerys' forces as the Lannisters make their move

HBO can’t catch a break.

Just a few days after HBO was hacked, an entire episode of “Game of Thrones” Season 7 has leaked online before its Sunday premiere.

A spokesperson for Star India, one of HBO's international partners, confirmed to Fox News Friday that Episode 4 of Season 7, titled "The Spoils of War," has made the rounds online. They receive episodes in advance of air.

"We take this breach very seriously and have immediately initiated forensic investigations at our and the technology partner's end to swiftly determine the cause," added the rep. "This is a grave issue and we are taking appropriate legal remedial action."

The recent leak is not believed to be part of the hack that occurred earlier this week.

Variety reported Monday that hackers may have leaked unreleased episodes of several HBO shows, as well as a script for “Game of Thrones.”

Entertainment Weekly added the episode may have leaked from Star India, one of HBO’s international network partners. They receive episodes in advance of air. Star India could have been hacked by the same parties that infiltrated HBO.

This isn’t the first time HBO has faced a similar battle.

Back in 2015, the first four episodes of “Game of Thrones” leaked online before the premiere of Season 5 after review DVDs were sent to the press. Consequently, HBO halted the practice of sending any episodes in advance.

That same year, several clips also leaked ahead of time from overseas HBO distributors. Images of Jon Snow’s death were also found online before the finale aired.

And just a couple of weeks ago, a “Game of Thrones” trailer aimed to be screened at Comic-Con leaked onto YouTube in advanced of its highly anticipated release.
