Game of Thrones' bummer-filled week continues. This Sunday's upcoming episode "The Spoils of War" has leaked online, the Verge reported Friday. This leak, however, is not related to the massive HBO hack, which also included various Game of Thrones-related material.

Instead, this episode leak stems from a security breach at HBO distribution partner Star India. "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," a Star India rep said Friday. "This is a grave issue and we are taking appropriate legal remedial action."

Though this most recent leak is unrelated to the 1.5 terabyte HBO hack, there were unconfirmed reports earlier this week that the same episode—in addition to last week's "The Queen's Justice"—had been compromised by those hackers. Multiple episodes of Ballers, Room 104, and Barry were also alleged to have been included. Additionally, Variety reported, hackers appeared to have leaked the personal information of a senior network executive.

In a company email obtained by Entertainment Weekly Monday, HBO CEO Richard Plepler assured employees that the initial "cyber incident" was being taken seriously. "Any intrusion of this nature is obviously disruptive, unsettling, and disturbing for all of us," Plepler said. "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."

Game of Thrones kicked off its season 7 madness July 16, drawing more than 10 million viewers for the premiere. Sunday's upcoming episode will put fans past the halfway point, as this season will consist of only seven episodes.
