A Star India spokesperson confirmed the leak to ET in a statement: "This confirms the compromise of episode four of Game of Thrones season seven, earlier this afternoon. 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. This is a grave issue and we are taking appropriate legal remedial action."
Earlier this week, HBO had a cyber security hack, resulting in a loss of some of its original programming, including material allegedly from Game of Thrones' upcoming fourth episode this season. However, the cable network confirmed to BuzzFeed News that the leaked episode "was not part of the recent hack."
